Description

Segmental precast concrete ventilating slabs of structure and construction way in tunnel for rapid installation}

The present invention relates to a tunnel wind tunnel slab, which provides a wind tunnel of a transverse type and a semi-transverse ventilation type, which is a wind structure of a tunnel in which a ventilation duct slab for ventilation inside a tunnel is installed, but of a slab installed for duct formation. Detailed structure for weight reduction and durability and structural principle for preventing collapse and how to install it quickly and safely, and the use of slab containing refractory material that can reduce the degree of impact on concrete in case of fire in tunnel It is recommended to relate to the structure and construction method of a segmented wind tunnel that can be rapidly installed in a tunnel to facilitate durability and maintenance of the wind tunnel in the tunnel.

As one of the general ventilation and fire suppression methods adopted in tunnels, adopting a wind tunnel is becoming a trend these days, and the structure and installation method of a segmented wind tunnel that can be easily installed in a tunnel is patent 10- It is registered and posted as 1793063.

In the Republic of Korea Patent No. 10-1793063, "The structure and installation method of a segmented wind-proof slab for easy installation in a tunnel",

In order to supply and exhaust air to the inside of the tunnel structure, a windshield slab crossing the upper side of the spring line in the tunnel is provided, and by a partition wall vertically partitioning the tunnel lining crown from the windshield slab top surface and the center of the windshield slab, In installing the tunnel wind tunnel slab for ventilation in the tunnel,

A tunnel lining bracket that protrudes inside the tunnel lining,

Hoist and chain block facilities installed in the center or both sides of the crown part of the tunnel lining,

The windshield slab divided into two sides is formed so that a pressure jaw, which is a protruding part, is formed on the upper surface of the central part, and the windshield slab end portions, which create a plurality of cavities in the inner transverse direction, are fixed to each of the tunnel lining brackets and are fixed on the central part side. The pressure jaw, which is the protruding part, has a wind degree slab to form mutual butt between the flat slabs,

When the wind degree slab is mounted, one side of the one-sided slab is mounted on the glove, and then the other side of the one-sided slab is mounted on each other by a butt, and then the hydraulic jack of the glove is gradually lowered to introduce compression force due to the weight of the two-sided one-sided slab. Winding slab to be installed or to be installed by adjusting the angle formed by the two-sided slab by installing a hinge node at the center of the wind-slab divided into two sides,

The windshield slab is formed of a windshield slab provided with a binding root 1 and a binding root 2 inside the wind tunnel slab, which is formed of a binding hole 1 installed on a pressure jaw of the upper surface of the windshield slab and a binding hole 2 installed on an inner surface of the center of the slab. It is characterized in that it is equipped with facilities to prevent the falling of and to stabilize the slab.

However, in the case of the above patent, it is a structure that cannot support the compressive force of the segmented-type windshield slab because there is no anti-slip protection provided by contacting the tunnel lining to prevent the windshield slab from being pushed when the windshield slab is placed on the bracket,

Since there are two binding muscles that fix the pressure jaw, economic efficiency is not only low, but in the case of the binding muscle 2, when the installation angle is small, the length increases, which may adversely affect the construction cost and workability.

Since the side structure of the wind degree slab forms a shape in which "a" and "b" characters are combined, it is a structure that prevents a step difference between the slabs, but it is very difficult to replace the one-sided slab during maintenance.

It is composed of a structure that uses a hoist or a vent when installing, which causes difficulties in quick installation.

The pressure jaw is composed of a flat surface with no irregularities, so when facing each other, there is no deviation and it is very difficult to face accurately.

It is necessary to install a bulkhead when ventilating in a cross-flow method, and it is a problem that needs to be improved by installing a H-beam between the tunnel crown and the pressure jaw to form a structure that is never advantageous from the construction cost.

Therefore, the present invention has been devised to solve the above-mentioned problems, and in particular, a cross-section thickness of the wind-slab is provided by providing a segmental structure to allow ventilation in the tunnel by providing a wind-slab in the tunnel by adopting a transverse or semi-transverse ventilation method. It aims to minimize and to significantly reduce the cost of construction, etc., and to improve the structure so that deformation of the structure is not caused by external pressure applied to the tunnel over a long period of time.

In addition, the present invention, as a safety device against shock waves such as earthquakes, relatively long wind-slabs are hung from PC steel wires or cables to prevent falling and increase safety while preventing sagging due to long-span, and the appearance of the tunnel. There is a second purpose to improve the openness of vision without harming

If possible, the third purpose is to make a structure that can be used at the site near the site rather than at the factory.

The fourth purpose is to create a structure that can be installed regardless of the width and slope of the tunnel.

The fifth purpose is to improve the bracket and make a structure that can mount the wind degree slab without compromising it.

The sixth purpose is to create a structure in which the movement of the bulkhead caused by wind does not occur while the low weight bulkhead is installed.

The seventh purpose is to create a structure in which the membrane structure can smoothly achieve its purpose and be removed by reinforcing the ring that connects the membrane structure with a short length when forming a cavity in the pungdo slab.

The eighth purpose is to create a structure that installs a divided knitting slab to form a single wind degree slab and prevents the divided knitting slab from being pushed toward the tunnel lining when compression force is generated.

The ninth purpose is to create a structure that effectively improves the binding jaws that tie the slabs following the pressure jaws to reduce construction costs and facilitate construction.

The 10th purpose is to make the side structure of the Pungdo slab advantageous for lifting and to make it easy to replace during maintenance, and to make the concave structure like the side on the podium to maintain the robustness by pouring mortar.

The 11th purpose is to install a partition on the transverse beam of the bogie so that there is no deviation in the pressure jaws between the flat slabs when they are loaded.

In order to shorten the air when installing a wind slab, a structure of a segmented wind slab capable of rapid installation in a tunnel having more than 12 purposes, including the purpose of the twelfth, to create a bogie structure capable of loading large quantities of slab slabs and It is to achieve the construction method.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention, as seen in the accompanying Figure 1, crossing across the spring side of the spring line 90 inside the tunnel 80, discharges contaminated air inside the tunnel 80, and supplies fresh air outside While stably mounting the wind degree slab 110 adopted for the transverse and semi-transverse ventilation methods, the thickness is not prevented, of course, the fall is prevented, and is provided for ventilation.

The present invention for this purpose, the spring line 90 inside the tunnel 80 is traversed across the upper side to be mounted crossing the wind duct slab 110 and the air duct of the exhaust and supply vents on the upper surface of the wind duct slab 110 In order to create a partition wall 150 is installed, this wind tunnel slab 110 has a conventional structure with the tunnel lining 100 inside the tunnel 80, as shown in Figure 1, the wind tunnel slab 110 ) It is preferable that the brackets 104 are integrally formed to face each other on the inside of the tunnel lining 100 so that both ends 103 sides are seated.

Here, it is preferable to install the bracket 104 as a reinforcing bar as shown in FIG. 8 to form a form in which the upper rebars are buried inside the lower hole 136 at both ends of the pungdo slab 110, which is a pungdo slab 110 ) Is to secure the position of the in place so as not to move, as well as a way to maintain stability even in the shaking phenomenon when an earthquake wave comes, because this makes it easy to install the tunnel lining (100).

8, the hole 114 is formed in the horizontal and inclined directions in the tunnel lining 110 facility, and the knife block 139 and the threaded female screw are provided in the hole 114. 140), the first and second in the state that the exposed reinforcement bracket (113) is fixed by rotating and installing the remaining bracket reinforcement (124) in the state installed in the tunnel lining (100) by installing the threaded small steel pipe (135) When mounted on the bogie (200',200"), pass through the bracket rebar 124 of the exposed rebar bracket 113 to the line 132 installed at the podium 103 side of the two-sided slab (110', 110"). In the lifted state, the bending of the rubber packing 117 is attached to the upper end of the exposed rebar bracket 113 which can install the non-shrinking mortar 118 on the side of the single-slab slab 110', 110" end 103. After the steel plate 116 and the rubber pad 141 are installed, the wind groove slab 110 end 103 of the lower groove 115 is fitted to the iron part of the bending steel plate 116, and the end of the single slab end 103 ) Side and bolt nut (BN), the reinforcement bar 125 is provided on the exposed reinforcing bracket (113), it is a method to pour shotcrete for rust prevention.

As another method, as shown in FIG. 18, the bracket 104, which is light on the tunnel lining 100, is installed in an intermittent, rather than continuous, form of any length, and the exposed reinforcement bracket 113 between the intermittent brackets 104 is provided. Bracket reinforcement (124) of the exposed reinforcing bracket (113) to the line opening (132) installed on both sides of the podium (103) side of the pungdo slab (110) arranged at intervals in the bogie (200', 200") After passing through), the bogie 200 is moved in the direction of the tunnel 80 by the length of one intermittent bracket, and the two-sided slabs 110', 110" are mounted at intervals on the upper surface of the bracket 104, Subsequently, the rubber packing 117 is attached to the podium in a state where it is raised by passing through the plinth-side line openings 132 of the two-sided one-sided slabs 110', 110", which are placed at intervals on the bogie 200', 200". The bent steel sheet 116 and the rubber pad 141 are placed on the upper reinforcement of the exposed reinforcing bar bracket 113, and the wind groove slab 110 is mounted, but the lower groove 115 of the podium 103 is bending steel sheet 116 iron (凸) To be fitted to the bolt nut (BN) to be fitted to the part, and the installation of the reinforcing bar 125, the tunnel lining 100 and the end side end 103 of the wind tunnel slab 110, a non-shrinking mortar 118 ), and there is a method of combining the bracket 104 and the exposed reinforcing bracket 113 for pouring rust-prevention shotcrete.

On the other hand, as shown in Figure 14, when the windshield slab 110 is placed on the bracket 104 and the exposed reinforcement bracket 113, the withdrawal rebar 119 protruding from the podium contacts the tunnel lining 100, so the windshield slab (110) should be installed so that it serves to prevent the pushing.

To this end, the pull-out rebar 119 protruding from the podium 103 of the pungdo slab 110 comes into contact with the tunnel lining 100, but is manufactured by bending the end of the pull-out rebar 119 with an arc, and pungdo slab 110 podium A plurality of threaded female screws 140 are installed on the (103) side, and the pungdo slab 110 is connected to the pull-out reinforcing bar 119 shorter than the depth of the threaded female thread 140 into the threaded female screw 140 ( 103) Adjusted to fit the space between the side and the tunnel lining 100, and the tunnel lining 100 is installed so as not to damage the curved portion of the withdrawal rebar 119 so as to contact the tunnel lining 100.

Meanwhile, as illustrated in FIGS. 1, 5, and 9, the wind degree slab 110 is preferably installed in a hat shape in which the central portion rises upward. This is a structural measure to prevent the occurrence of sagging due to self-weight, and to prevent the wind slab 110 from falling off, and to create a structure that mechanically converts the vertical force in the downward direction to the compressive force in the oblique direction, so that the moment is reduced. This is because it is intended to improve safety by inducing it, and it is a measure to secure a wide field of view by increasing the feeling of openness to the driver.

As one of the principles of the above structural measures, as shown in FIG. 14, the withdrawal rebar 119 installed on the podium 103 side is not in contact with the tunnel lining 100 so that the podium 103 side of the pungdo slab 110 is not pushed. As the pressure jaws 101, which are the central protrusions of the two sides of the pungdo slab 110 that are inclined in a slant shape, gradually come into contact with each other, they mutually support each other, so that the pungdo slab 110 is no longer sagging downward. Since the vertical force by acts as a compressive force concentrated on the withdrawal rebars 119 on both ends 103 along the inclined pungdo slab 110, a principle of relatively stable feeling is used.

Therefore, a large horizontal force acts on the withdrawal rebar 119, and a small vertical force acts on the bracket 104, so that it can be converted into a safer structure.

However, when the span of the wind degree slab 110 is remarkably long, it is impossible to solve the increase in deflection and moment by butt support, but the clasp as shown in FIG. 6 is used as a reinforcement method in this case. It will be desirable to install (111) and install a resistance facility that is tied to the wire 112, such as a hook 109 and a pc stranded wire and turnbuckle or cable woven on each reinforcing bar of each of the flat slabs.

When explaining the configuration of such a wind degree slab 110, as shown in FIG. 12, a plurality of cavities 102, which are configured to be long in the horizontal direction of the wind degree slab 110, are formed, and concrete is formed on the lower surface and the upper surface of the cavity 102. In order to secure the toughness of the wire, a wire reinforcing bar and a wire mesh or a pc stranded wire 112 are selectively arranged to be manufactured. The reason for forming the cavity 102 is to lighten the self-weight of the wind tunnel slab 110.

As a method for forming the cavity 102, the present invention adopts the structure according to FIG.

In other words, to form the cavity 102, before pouring the concrete of the windshield slab 110, a formwork having a shape suitable for the cavity 102 must be formed, and the formwork is removed after curing the concrete of the windshield slab 110 Although it is absolutely necessary to manufacture a lightweight wind-proof slab 110, significant difficulties have arisen in removing the formwork.

The present invention is to solve this problem, as shown in Figure 9, a polyvinyl chloride-based air rod having the shape of a cavity 102 (hereinafter referred to as'membrane structure' in the specification of the present invention) and vinyl (122) ) Is provided in advance before pouring the wind degree slab 110, and then, in order to have the shape of the cavity 102, air is injected into the membrane structure 120 before pouring concrete to form a solid air rod, and the membrane structure 120 ) After applying water on the outer surface, apply the plastic 122 and fix it in a predetermined position so that the length of the cut slabs 110' and 110" protrudes outward.

However, since the membrane structure 120 is produced with a length of a short side, as a reinforcing material that connects the seams generated between the lengths of the air rods, the outer side of the air rod is cut by cutting the short-sided exterior 3 to 4 times in the longitudinal direction as shown in FIG. 12A. After you tie the band, wet it with water and cover it with vinyl (122).

In this state, the hole is made toward the cavity 102 from the upper surface of the concrete of the wind degree slab 110, and the air injected into the membrane structure 120 is crushed as the air is blown out through the hole to explode. When the worker pulls the membrane structure 120 protruding to the outside, the membrane structure 120 and the cut short-sided exterior 121 are recessed so that the membrane structure 120 can be easily removed together with the vinyl. (122) will remain attached to the main surface of the cavity 102 as it is, so that the weight of the vinyl 122 is light, so that it is possible to significantly reduce the weight in the wind degree slab 110.

As another method for forming a cavity, as shown in FIGS. 12A and 12B, the membrane structure 120 and the long side exterior 133 are incised 3 to 4 times in the longitudinal direction as the short side exterior 121, and in several places. Tied with a band, moistened with water, covered with vinyl (122), fixed in a predetermined position, and after remicon pouring and curing, making a hole toward the cavity (102) from the concrete top surface when manufacturing the slab slab (110',110") Through this, the band bundle may be disassembled to depress the incision surface, or a lubricant 134 may be applied to the surface of the long intestine exterior 133 that is not incised, and then a method of extracting and removing them may be used.

Here, the number and shape of the cavities 102 are not limited to the above-described examples, and it is needless to say that it may be implemented in various numbers, shapes and shapes.

Meanwhile, as shown in FIGS. 4 and 5, the wind degree slab 110 takes the form of a two-segmented dividing structure rather than a conventional tubular slab structure, and in that form, the two-segment slabs 110' and 110" The lower surface of the podium 103 side has a flat structure in accordance with the upper surface of the bracket 104, and is installed in the form of a hatchet structure, which is inclined from the podium 103 side to the central side and the central side rises upward. The leading end of the cutting slabs 110' and 110" is supported by the tunnel lining 100 so as not to be pushed, and consists of a pressure jaw 101 in the form of a structure protruding upward in the center side. ,110") to form one wind degree slab 110 by inclining to face each other.

Here, the role of the pressure jaw 101 shown in FIG. 5 is that when the left and right articulated slabs 110' and 110" face the pressure jaw 101, which is the central protrusion, mutually, the force is transmitted downwardly due to its own weight. As the horizontal force is transmitted to the withdrawal reinforcing bar 119 of both ends of the (110), a process of achieving stability occurs. At this time, the pressure jaw 101 is in close contact with the compressive force to prevent the sagging downward. It is composed.

On the other hand, the pressure jaw 101 is integrally formed with the central end 103 of the slab, and thus, a facility is required to tie both of the two-segment slabs 100', 100". (101) is placed at a regular interval at the bottom of the slab where the abutment is made, and the binding hole 107 is buried, and the reinforcing bar 108 of the curved reinforcing bar or pc strand is fitted, and from the binding jaw 127 to the filling nut 126 Since it is to be tightened, it is composed of a hinged joint, not a rigid joint.

However, in case a rigid bonding is required according to the site conditions, the rigid bonding is configured as shown in FIG. 15.

15A is a case where the pressure jaw 101 of concrete is integrally formed at the center end 103 of the two-sided slab (110', 110") as a reinforcing bar at the upper side binding hole 107 of the pressure jaw 101 The configured binding muscle 2 (108') is placed and placed at close intervals, and the binding muscle 108 composed of a reinforcing bar or a PC steel strand is fastened with a filling nut 126 to the binding opening 107 formed as a curved surface on the lower side of the slab. It consists of a rigid joint consisting of two points of fastening at the top and bottom.

15B is another method for constructing a rigid bond in the structure in which the binding muscle 108 is fastened to the binding hole 107 formed as a curved surface under the center edge 103 of the two-sided slab (110', 110") In place of the pressure jaw 101 of the concrete, the upper surface of the slab is made into a flat structure, and T-shaped steel 136 is disposed to fix the two sides of the slab (110',110") and anchor bolts (AN) for rigid bonding. It is advantageous to apply this method to the semi-transverse ventilation method.

In the case of 15b1, a structure in which two pairs of bore-shaped steels 137 having four-way rebars are fastened with a bolt nut (BN), and in the case of 15b2, H-beams 138 are arranged instead of the T-beams 136 Therefore, it is easy to install the partition wall 150 structure adopted in the cross-flow ventilation method by forming a flat structure.

In such a configuration that no further sagging occurs, it would be desirable to supplement this by additionally installing an external binding muscle 108 using the pressure jaw 101. This is because in case of safety in consideration of safety as a priority, in order to do this, first, when manufacturing the one-piece slab (110',110"), a hole is formed at the bottom of the position where the pressure jaw 101 comes into contact with the binding hole ( 107) is required to be buried in advance, which is to insert the binding muscle 108 into the binding opening 107 and fill it with the filling nut 126.

It is natural that the binding jaw 127 is pre-configured when manufacturing the one-piece slabs 110' and 110" in order to fasten and fix the binding muscle 108, and such binding muscle 108 is in the direction of the tunnel Arranged at regular intervals to act as a restraint so that the windstorm slab 110 itself does not shake even when an earthquake or other vibration occurs, and even if the pressure jaw 101 is destroyed, the windbreak slab 110 does not fall. In addition, a reinforcing bar, a PC steel wire, etc. can be selectively used as the material of the binding muscle 108, and the material is not limited to any one material.

As shown in FIG. 1, the shape of the wind duct slab 110 can be configured in a divided fixed form in which each of the two-segmented one-piece slabs 110' and 110" is separately manufactured and lifted with a crane or the like to be installed to be in contact with each other. .

As described above, the divided fixed configuration is a primitive method of manufacturing and installing each of the one-piece slabs 110' and 110" so that the pressure jaw 101 comes into contact manually by lifting of a crane, etc., which is relatively simple. It is made of a structure, and the manufacturing method is simple, and the shape of the circle in the center of the pressure jaw 101 is as shown in FIGS. 5 and 9b1 to reduce the inconvenience of the operator having to artificially fit the pressure jaw 101 and to ensure accuracy. Since the fitting device 131 of several uneven structures and the thin filler material 142, such as a rubber pad around it, are configured to fit in a positive and negative pressure jaw irregular surface so that they fit together, the binding hole 107 Both ends can be matched, and in order to achieve this, the section 128 is installed in the transverse beam 203 of the bogie 200 at the end-side end 103' and the center-side end 103" of the transverse slab 110' ,110") is placed in the correct position of the bogie 200 so that it is correctly mounted on the bracket 104 or the exposed reinforcing bar bracket 113.

On the other hand, in the airflow slab 1100 having a unit shape, a vent hole should be formed to allow air supply and exhaust at regular intervals, and the end 103 side of the vent hole is placed on the bracket 110 to be seated, and a wide vent hole is provided. It is preferable to construct such that the H-shaped steel is embedded in both sides of the formed wind degree slab 110 and the bracket 104, so that rigidity is maintained. This is because the connection with the Pungdo slab 110 may be difficult. In addition, if only one segment of the windshield slab 110 is not sufficient to secure a ventilation hole in the windworthiness, it is necessary to secure a ventilation area by opening the ventilation hole in another adjacent segment windshield slab 110.

In addition, as shown in FIG. 14, the withdrawal rebar 119 formed as a measure for preventing the knitting slabs 110', 110" from being pushed on the upper side of the bracket 104 of the tunnel lining 100 is described above. ,110") Install the one-piece slab (110',110") in such a way that it is connected to the tunnel lining (100) by combining it with a threaded female screw embedded on the end (103) side, preventing destruction by friction between concrete To do this, the rubber pad 141 is installed on the upper surface of the bracket, and at this time, a concave structure such as a side surface is formed on the side of the podium 103 to pour the non-constriction mortar 118 at a distance from the tunnel lining 100. In order to effectively block the flow, and to improve the bonding properties, in addition, the silicon (to block the flow of air also on the upper surface of the part where the pressure jaw 101, which is the center-side protrusion of the wind degree slab 110 is in contact with each other, 129).

On the other hand, the windshield slab 110 has a segment structure formed as one unit as described above, and is mounted on the bracket 104, so that the windshield slab 110 and the side surface of the other windshield slab 110 in contact with the side surface Bonds must be made.

That is, for this purpose, a side coupling structure is provided between the wind degree slabs 110 as shown in FIG. 13, and both side surfaces of the wind degree slabs 110 have a concave structure in a symmetrical shape to form a bonding end 130 and the bonding It is preferable to form the structure of the stage 130 firmly. This is to configure the jaws so that the mechanical lifter can bite to lift the single-piece slabs (110', 110"), and to fill so as not to generate a step due to the displacement difference between the respective wind degree slabs (110). And to facilitate maintenance, and to facilitate sealing to prevent air from leaking.

As the sealing material, silicon 129 is injected into the lower surface of the slab bonding end 130 and the non-shrinking mortar 118 is filled more than that, on the side surface between the wind degree slab 110 and the wind degree slab 110. The gap is filled to complete.

In addition, there are two methods of using the bogie 200 as a method for installing the above-described wind degree slab 110, the first bogie 200' for mounting the wind degree slab 110 that can be adjusted up, down, left, and right and up and down. It can be divided into a second bogie (200") for mounting the Pungdo slab (110), which can only be adjusted by Roman.

First, in the case of the former as shown in FIG. 9A, the main beam 201 of the water tank is arranged in two rows in the lateral direction, and the vertical beam 208 is installed at the upper and lower ends of the main beam 201, and the vertical beam 208 is adjusted on the lower vertical beam 208 of the lower main beam 201. This adjustable hydraulic jack 209 is installed, a 360° rotary rubber wheel 216 is installed under the vertical beam 208, and a horizontal beam 203 is installed at the upper vertical beam 208 of the main beam 201, but each vertical beam ( 208) while forming two segments of a relatively short shape fixed to each other, and placing c-beams 207 with fixed ends on both sides of the inner left and right sides so that the first bogie 200' can be adjusted to the left and right. There is, the transverse beam 203, the upper end side end (103') constitutes a cushioning material 210, and the central side end (103"), as shown in Figure 11, the support beam 211 or the low pressure jack 212 and the buffer material 210 ) To support the support beam 211 and the low pressure jack 212 to form a hatch and be inclined, and the low and high pressure jack 212 can be used to adjust the top and bottom of the flat slabs 110' and 110". To make.

On the other hand, when looking at the structure of the transverse beam 203, as shown in FIGS. 9A2, 9A3 and 10, the central portion of the transverse beam 203 is cut at a certain distance and spaced apart. 207) is embedded in advance, but one side transverse beam 203 is fixed to one right side c-beam 207 and arranged to move in connection with the left side web of the other side transverse beam 203, and the right side of the other side transverse beam 203 One c-beam (207) is fixed to the web and is arranged to move to the left web on one side of the transverse beam (203), so that the left and right sides of the first bogie (200') can be moved to narrow. ,

The transverse beam 203 may be arranged to be inclined so as to form the shape of the hatch by the vertical slab 211 or the low pressure jack 202 placed on the upper side of the central beam, and fixedly connected to it The cushioning material 210 is intended to prevent the damage that comes from the steel slabs 110', 110" and the first bogie 200' directly in contact with each other, and the low pressure jack 202 is a single slab 110', 110" ) Is in charge of the function of adjusting the up and down angle, and this function is also a measure that enables close access so that there is no error between the cut slabs 110' and 110".

Next, in the case of the latter as shown in Figure 9b, the main beam 201 of the water tank is arranged in two rows in the lateral direction, and a vertical beam 208 is installed at the bottom of the main beam 201, and the vertical beam 208 is adjusted on the lower vertical beam 208 of the lower main beam 201. This adjustable hydraulic jack 209 is installed, a rotary rubber wheel 216 is installed under the vertical beam 208, and a horizontal beam 203 is installed at the top of the main beam 201, but hinged by each main beam 201. It is arranged to face each other while forming two segments of the connected shape, and the angular hydraulic jack 204 is hinged to the main beam 201 as shown in FIG. 9B2 at the bottom of each transverse beam 203, and installed at the bottom of the center side of the transverse beam 203. By supporting one jaw L steel 212, the transverse beam 203 rotates to adjust the angle. In addition, the angle hydraulic jack 204 has a long length and a large weight, so the angle hydraulic jack 204 is tied with a wire connecting the connecting rod 213 connecting the upper ring below the lateral beam 203 and the main beam 201 under the hinge. ) To use the wire that can be automatically stretched according to the angle of

Since the lateral beam 203 supported by the angular hydraulic jack 204 is facing close, the second bogie 200" cannot be adjusted from side to side.

On the other hand, looking at the structure of the transverse beam 203, the transverse beam 203 is disposed between the two sets of main beams 201, but connected by a hinge, and the angular hydraulic jack 204 supports the chin L cavity 212. The lateral beam 203 is rotated by the angular hydraulic jack 204, or the elliptical groove 218 is moved around so that the lateral beam 203 is moved inward in the process of forming an upward angle by the angular hydraulic jack 204. ).

In addition, as shown in FIGS. 9B3 and 9B4, the two-segmented central portion of the transverse beam 203 is firstly arranged with a C-shaped steel 207 that can be moved back and forth by means of a fixing pin 217 on either side and on the other side, and the windshield slab ( After the work of putting 110) on the bracket 104 is finished, it is connected to both sides of the web in order to hold it so as not to be shaken when the horizontal beam 203 is leveled for movement to the manufacturing site and the yard, but it is either side horizontal beam. (203) One U-shaped steel 207 is disposed on the right web so that it is arranged to move in connection with the other side transverse beam 203, and one side U-shaped steel 207 is disposed on the right web. By arranging and arranged so as to be moved to move to the left web on either side of the transverse beam 203, it is configured to prevent the sagging of the transverse beam 203,

On the other hand, at the end of the c-beam 207 embedded in the transverse beam 203, a maguri plate 205 is installed in accordance with the inner specification of the H-beam 138 to prevent displacement, and the flat slab 110', 110" 9A and 9B, as shown in FIGS. 9A and 9B, the non-slip jaws 215 installed under the center and end side edges 103" and 103' and the center and end side edges 103" and 103' as shown in FIG. 203) The partition 128 arranged on the top is installed to prevent slipping due to inclination and to make the correct loading on the first and second bogies 200' and 200", and the bracing steel installed on the main beam 201 ( 214) to prevent internal and external shaking,

The first and second bogies (200',200") by these two methods have a plurality of first and second bogies (200',200") on top of each tank with a windpipe slab (110). Since it is configured to move in a line, it can be regarded as a great advantage that it can significantly shorten the air due to the high speed of unloading and installation. As shown in FIG. 9A1, the flat slab (110', 110") is lifted. The pressure jaws of the one-way slabs (110', 110") in the opposite direction because they are placed in the partitions (128) installed in the anti-skid jaws (215), which are determined at the top of the first and second bogies (200', 200") by the equipment. 101).

On the other hand, in the case of the cross-flow type ventilation system, a partition wall 150 capable of distinguishing air supply and exhaust air from the airflow created on the upper surface of the windbreak slab 110 should be installed. As shown in FIG. 1, tunnel lining 100 ) After the upper portion of the crown and the upper end of the windshield slab 110, the pressure jaw 101, a partition wall 150 in which mutual air flow is blocked is installed.

Since the partition wall 150 is a facility that induces a one-way flow of air, an upper partition wall as shown in FIGS. 3 and 5 is installed at the top of the crown portion and the top of the wind duct slab 110 pressure jaw 101 to fix the partition wall 150. The fixtures 151 and the lower partition wall fixtures 152 are respectively installed, and the partition walls 150 having relatively light materials are prevented from communicating between the left and right sides, and the partition walls 150 are light and intermediate. Since there is a seam, deformation by air may occur. If there is no fitting 154 in the product itself, it can be connected by a separate fitting 154. Since the deformation of the wave may be caused by pressure, the partition wall 150 is installed inside and outside at the upper and lower ends to prevent this, so that the partition wall 150 is not warped and maintains upright. .

Here, it is needless to say that silicon 129 is processed on the upper and lower surfaces of the partition wall 150 to prevent air from passing through.

In the detailed description of the present invention, the configuration of the wind degree slab 110 has been described so far. In the tunnel 90, fires due to various accidents such as a vehicle contact accident and an overturn accident may occur. As a countermeasure, there is a method of attaching the refractory material 123 to the windshield slab 110, but this may not be a fundamental countermeasure because special care must be taken for maintenance because there may be a possibility that the facility may escape as the aging of the facility progresses.

Therefore, as one of the methods for preventing damage to the structure of the windshield slab 110 due to heat generated by the fire, in the present invention, when manufacturing the windshield slab 110 as an example, the fireproof mortar or plastering the windshield slab 110 Installed on the bottom side, the wind-resistant slab 110 is constructed of a fire-resistant structure that can withstand heat, and a sprinkler is installed around the tunnel lining 100, bracket 104, and water or chemicals that extinguish the fire are sprayed. Therefore, it would be desirable to apply any one of the methods of extinguishing a fire.

To create a fire resistant structure to achieve this,

Must be produced as a fireproof structure when drying the windshield slab 110. To achieve a fire resistant structure, the windshield slab 110 is turned over, the concrete is first poured into the upper surface of the structure, cured to some extent, and then poured into the fire resistant material. Synthetic, so that the lower surface of the one-piece slab (110', 110") forms a fire-resistant structure, or the fire-resistant mortar or plaster separately produced before the structure in which the ready-mixed concrete constituting the wind-resistant slab 110 structure is cured is 110 ) A variety of methods can be applied to pour on the lower surface and cure or select any one of these materials to adhere to the surface by spraying and attaching to the windshield slab 110 structure where installation and assembly are completed. There will be.

First, first, in the case of the one-piece slab (110',110") synthesized by pouring a ready-mixed concrete on the upper surface of the one-piece slab (110',110") and placing a refractory admixture on the lower surface of the structure, a separate exterior material It is simple by pouring it to form an integral structure without attaching it, and it has an advantage of simple process because it is an integral wind-resistant slab 110 that makes fireproof. It is characterized by the fact that the method of poetry cannot be applied and the second method of spraying must be applied.

Secondly, a method of applying a surface may be applied since one of the respective materials is selected and poured one after the other, which is before pouring the ready-mixed concrete on the upper surface of the wind tunnel slab 110 structure and before complete curing is achieved. It has the disadvantage that the refractory material 123 may drop out during transport and installation in the field to form an integral structure by placing refractory mortar and plaster on the lower surface of the structure, but it is created only on the lower surface of the wind resistance slab 110 that requires fire resistance. It may be somewhat positive in construction cost.

Third, it is possible to apply a method of selecting any material of the refractory mortar and plaster to adhere to the surface by spraying it, which is constructed by drying and assembling all of the structures of the wind slab 110 to wind the slab 110 ) Since it is a method of spraying on the front surface of the structure, it may be somewhat positive in air and construction costs, but in this case, a high rate of repulsion is consumed, so proper adsorption technology should be incorporated.

Apart from the above methods, there is a method of adding a refractory tile or the like produced by selecting any one of the above materials to the structure, but the construction process is complicated and the life of the tile may not be permanent and the tile may be damaged. If there is a disadvantage that can not exhibit fire resistance,

Alternatively, when pouring the ready-mixed concrete, a method of mixing the refractory admixture with the pouring of the refractory admixture on the lower surface of the structure can be applied. The production cost will be determined, and since it is an integrated wind-resistant slab 110 that is fireproof, it has the advantage of being simple and requires no maintenance, while the production price can be increased and the rigidity of the body structure can be reduced. There is,

There is a method of attaching a refractory sheet paper to the structure, such as wallpaper, but this should be avoided because it is judged that the adhesive will weaken the adhesive force due to heat, and if it is maintained for a long time, dropping or lifting and deformation may occur.

On the other hand, there is a method to extinguish a fire by installing a sprinkler near the slope side of the tunnel lining 100 and the brackets 104 on both sides and spraying water or chemicals to extinguish the fire by diagonal lines, but there are also various types of oil in the fire. Different fire extinguishers according to fire, metal fire, etc. are different, so the method of extinguishing a fire using a sprinkler may not be very efficient, but it can be achieved for the purpose of extinguishing by selecting one type. It can be watered.

As other materials may adversely affect nearby vehicles, it is desirable to refrain from using them as much as possible. Since water use poses a danger of freezing in winter, it is considered that the facility should be installed after taking appropriate measures.

As described above, the characteristics of the various cases other than the above three methods are described according to the site conditions, and accordingly, an appropriate product and method should be selected according to the user's judgment.

The above-described wind-proof slab 110 may be compared with a conventional tubular structure product. Since the above-mentioned wind-proof slab 110 forms a two-segmented structure as described above, the conventional arched structure which is a tubular structure and Daldaegu Since the tank and its format are different, it can be seen that they are markedly differentiated in terms of structural principles, safety and constructability, economics and use.

That is, the arched wind-proof slab 110 may be applied in a case where the width of the tunnel is relatively small. In this case, since the span is short and the amount of deflection due to its own weight will be less, the applicability is high, but the width of the tunnel is wide and the span is If it is long, the amount of deflection caused by self-weight is large, so it is installed in a structure that is hung on the PC steel wire for prevention of dropping, or the thickness of the wind duct slab is greatly increased, and the PC steel wire is placed in the slab so that the rigidity can be maintained. It can be said that this is maintained.

This arch-type Pungdo slab 110 should be manufactured in a specialized PC factory equipped with production facilities because it is necessary to install a PC steel wire inside to introduce compression force by a pretension method. There is a problem such as an increase in transportation costs due to an expensive point and a distance from the site.

In addition, because the wind road slab 110 itself is large, it increases the self-weight and uses a large crane, which increases construction costs and is difficult to handle, so it is a burden that frequently occurs in construction accidents, which has severe disadvantages in terms of safety, constructability, and economy. ,

In the case of a moon-frame structure, the anchor portion of the tunnel lining (100) is a two-part structure that holds the steel plate structure that acts as a moon to hold the structure of the H-beam (133). ), it is necessary to prepare for the prevention of rust in the steel structure, and when the one-side slab (110',110") is fitted, there is a risk of shaking and falling due to eccentric loading, and one-sided to H-beam 133 It is very difficult to fit the slab (110', 110"), the construction performance is deteriorating, and the displacement can be large due to the large load on the flange of the H-shaped steel (133). There is no risk of falling due to the shaking caused by the seismic wave, measures are needed to reduce the self-weight of the windbreak slab 110, and when buckling of the steel plate for hanging occurs, a step between the windbreak slabs 110 occurs and air leaks On the other hand, when the fire occurs, the H-beam 133 is weakly vulnerable to heat, and it is a structure that can be rapidly burned, leading to a risk of damage.

The proposed method, the segmented wind duct slab 110, uses the pressure jaw even when the tunnel has a wide width, and the wind duct slab 110 can mutually support each other to suppress sagging due to its own weight and to prevent the falling of the PC stranded wire. This is unnecessary, and it is possible to introduce a PC stranded wire into the slab, but it is also possible to introduce a compressive force by a post-tension method, so it is possible to make a field production, not a factory production, and also reduce the number of locations. The slab can be made thinner, and can be installed in the field up to the common site, so that the weight of the lifting equipment can be reduced in size and rapid mass mounting, so it is equipped with conditions that are quite advantageous in terms of safety, constructability, economy, and air. It is improving the shortcomings of the arched pungdo slab (110) structure and the suspension structure.

Construction method of segmented wind-proof slab structure

In the construction method of the segmented wind duct slab crossing the upper side of the spring line 91 in the tunnel 90, the construction method
