Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a structure for supporting a work member such as a rope or a scaffolding stand on a slope having a slope covered with a mortar, concrete or the like.

[0002]

2. Description of the Related Art Generally, a steep slope formed by cutting a mountain or a cliff is formed by a mortar spraying method or a concrete laying method to prevent the surface from collapsing. Is done. In recent years, many of the coated slopes have become obsolete, and have been subjected to severe earthquakes or left uncovered slopes that do not satisfy construction standards. Such a slope has many cracks and partial peeling on its surface, and the slope and ground slope have been affected by disasters such as deformation due to earthquakes and runoff of sediment due to heavy rain. It is in a dangerous state where it has been left in a state where it has been lifted or a peeling gap has occurred between itself and the surface.

[0003] Conventionally, in the dismantling work of an old or poorly covered slope, a lifeline is attached and fixed to a tree planted on the topmost ground of the slope when the slope is steep and high, and the lifeline is relied on. Workers operate crushing machines such as mortar cutting cutter devices and mortar crushing device with chisel for crushing mortar. By making a cut in the vertical direction and, if necessary, the horizontal direction, and crushing this part locally, the covering slope is made to be a small crushed material and dropped downward to be sequentially dismantled.

[0004]

However, in the case of the above-described conventional dismantling of the coating slope, in the case of the coating slope by the mortar spraying method, a substantially uniform layer thickness (substantially uniform) is applied along the shape of the slope surface. 1
(Approximately 00 mm), and the work done using only a lifeline on a steep sloped slope requires a heavy scaffolding and slippery work, as well as a heavy cutter device and other work equipment. However, since the user must carry the device at all times and work in an unreasonable working posture, there are disadvantages such as requiring a high level of skill and skill in the work and easily dropping the object after letting it go.

[0005] Therefore, it has been attempted to install an auxiliary rope along the middle of the covering slope on the lifeline and install a scaffolding stand. However, these working members are fixedly supported by drilling holes in the covering slope. Since the opening is performed by a fixing means such as driving an anchor after opening, there are problems such as complicated work, a long time required, and difficulty in implementation. Also, when a construction inspector other than the worker intends to inspect the covering slope that has been completed by mortar spraying work, climb to a high place on the covering slope using the lifeline or auxiliary rope as described above. Since it is difficult to perform the process sufficiently, there is a problem that the discovery of the defective coating construction part is easily overlooked.

[0006]

An embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a slope 1 of a ground or the like.
FIG. 1 shows a coating slope obtained by coating a with a mortar spraying method to a predetermined spraying layer thickness. FIG. 1 shows a working method using a working member supporting method and a structure according to the first and second embodiments of the present invention. An appropriate rope 2 having flexibility as a support guide, which is one embodiment of the member, is stably supported along the vertical direction of the covering slope 1, so that the worker climbs uphill using the rope 2. It shows an operation mode in which various types of slope work such as transportation of articles and equipment or inspection and dismantling of the covering slope 1 can be performed efficiently and safely.

The covering slope 1 shown in FIG. 1 is constructed by, for example, a conventional mortar spraying method for protecting a slope 1a formed by cutting the ground. That is, in this mortar spraying work, a net (not shown) such as a rhombic wire mesh for reinforcing a mortar spraying layer is laid on the slope 1a by floating about 50 mm from the ground surface, and then a spring from the ground is formed. Drainage holes 10 with a diameter of about 40 to 50 mm for draining rainwater are buried and installed with a spacing of about one per 3 square meters or an interval of about 2 m between adjacent drainage holes 10. In this state, the coating slope 1 is formed by spraying a mortar to a design thickness of about 100 mm using compressed air while checking the spray layer thickness with a measuring pin.

The drain hole 10 in the illustrated example is formed by cutting a drain pipe 11 formed by cutting a PVC pipe to the above-mentioned design thickness or a length slightly protruding from the surface of the coating slope 1 with a downward inclination. Although it is installed by a general construction means for draining by supporting and burying with a mortar, in the practice of the present invention, the drain hole 10 is used without using the drain pipe 11.
May be directly formed.

First, with reference to FIGS. 1 to 5, a first embodiment relating to a method and structure for supporting a working member on a coating slope according to the present invention will be described. The method of supporting this working member is
An embodiment in which a rope 2 is used as a work guide extending along a vertical direction or a lateral direction of a covering slope 1, which is one embodiment of a work member, is shown. As shown in FIGS. 2 and 3, the fixing tool 3 inserted and fixed in the drain hole 10 and a structure in which a plurality of portions are connected by a support rope 5 for supporting the middle part of the rope, the structure of the rope 2 along the covering slope 1. The installation and support can be performed easily and accurately.

In the illustrated example, the rope 2 and the support rope 5
In order to perform the connection quickly and stably, the connection is performed by using a connecting tool 6 integrally having a rope supporting portion 60 for fixing the rope 2 and a supporting rope fixing portion 61 for fixing the supporting rope 5. At the same time, for example, a commercially available clip or shackle-type attachment 50 is provided on both sides of the support rope 5, and the connection 50 of the fixture 3 and the support rope fixing portion 61 of the connector 6 are provided by the attachment 50. And are detachably connected to each other.

The supporting rope 5 is provided with a fastening device 51 such as a loading device of an appropriate type in the middle of the supporting rope 5 so that the fixing device 3 and the connecting device 6 can be connected to each other by the supporting rope 5. It can be easily pulled and supported in the tightened state. Note that the rope 2 and the fixing device 3 can be used without using the connecting device 6 and the mounting device 50 or the tightening device 51.
May be directly connected to each other by connecting means such as a string knot by the support rope 5.

Next, the detailed structure of the support structure for the rope 2 will be described. First, the fixture 3 shown in FIGS.
A fixed cylinder 31 having substantially the same length as the outer diameter that can be inserted into the drain pipe 11 and a fixed shaft 32 for providing a fixing action to the fixed cylinder 31 and connecting the support rope 5. This fixture 3
A fixed shaft 32 on one side of a fixed cylinder 31 via a screw portion 33.
Is formed so as to be able to advance and retreat, and a plurality of slits 34 are formed in the other side in the axial direction to form a fixed movable piece 35, and the inner surface of the fixed movable piece 35 is increased in diameter toward the front end. Formed on the tapered surface 35a.
and a tapered surface 32a formed on the fixed shaft 32 is joined to the fixed movable piece 35 so as to be able to advance and retreat. 35b is formed.

The fixture 3 configured as described above is used for the drain pipe 11 in the non-fixed position shown in FIG.
When the fixed shaft 32 is rotated to be pulled out (in the direction of the arrow) as shown in FIG. 2 in this fitted state, the tapered surface 32a at the shaft end becomes a tapered surface. 35a, and a plurality of fixed movable pieces 35 are simultaneously pushed out in the diameter direction, so that the outer shape is expanded, and the engaging portion 35b presses the inner surface of the drainage pipe 11 to bite into it. Is fixed to the drainage hole 10 through the drainage pipe 11 in a state in which the fixture 3 is reliably prevented from being pulled out. Therefore, when the support rope 5 or the scaffolding stand 20 described later is provided on the connecting portion 30 provided on the fixture 3, these can be stably supported with a simple configuration and mounting work, and the fixed support is released. When the fixed shaft 32 is rotated in the reverse direction, the fixed movable piece 35 returns to the original non-fixed posture by its elastic force, so that the fixing tool 3 can be easily removed.

The fixing device 3 is not limited to the outer diameter expanding type as described above, but may have a structure as shown in FIG. 4, for example. That is, the fixture 3 in the same figure has an outer diameter that can be inserted into the drainage pipe 11 and has a connecting portion 30 similar to that described above. The engaging portion 36 and the engaging portion 37 which can bite and lock on the inner surface are formed so as to protrude, and the other end of the fixing tool 3 is elastically removably connectable to the other end in the drain pipe 11.
Is provided with a temporary holding piece 38 for preventing the sliding down. When the fixing tool 3 is inserted into the drain pipe 11 and pulled in a direction along the surface of the covering slope 1 by the tightening of the support rope 5 attached to the connecting portion 30, the engagement occurs. Since the portions 36 and 37 firmly bite into the inner surfaces of the drainage pipe 11 on the back side and the entrance side, respectively, it is possible to easily perform fixing with a simple and inexpensive configuration in which retaining is prevented.

The fixing device 3 configured as described above is used for supporting a rope 2 or a support guide such as a guide rail 2 described later.
For example, as shown in FIG. 1, as shown in FIG. 1, a scaffolding base 20 as an ascending and descending assisting tool when an operator performs a covering surface work or ascending and descending, or a covering as shown in FIG. Work supports (not shown) such as shelves and scaffold frames for temporarily supporting tools and dismantling work machines such as a covering slope work machine 7 to be described later can also be attached and supported on the slope 1. is there. Therefore, since the fixing tool 3 is fixed to the covering slope 1 by using the existing drainage hole 10, it does not rely on a driving fixing means such as punching a hole in the covering slope 1 and then driving an anchor. This can be omitted, and a scaffolding frame structure that moves along with the rope 2 or the like as a work guide, supports the body using the scaffolding stand 20 or the like, supports the equipment, or frames along the covering slope 1. There is an advantage that various coating slope work such as installation support can be performed efficiently and conveniently.

The fixing tool 3 which requires a large number of bolts in the work of the wide covering slope 1 is formed by using the drain holes 10 provided at substantially predetermined intervals with respect to the covering slope 1.
Since the size can be reduced to about the size of the drain pipe 11, the length of the auxiliary rope 5 as an auxiliary support member can be standardized to a predetermined size in advance. There are advantages such as that the configuration can be made simple, compact and easy to handle. The connecting portion 30 is not limited to the structure shown in the illustrated example, and if it is provided in a rotatable configuration on the outer periphery of the fixed shaft 32 or the fixed cylinder 31, the connecting portion 30 is fixed with the support rope 5 attached thereto. There are advantages such that the shaft 32 can be efficiently rotated using a transmission driver or the like.

Next, the connector 6 will be described with reference to FIGS. The connecting member 6 has a rope support portion 60 having a U-shaped shape through which the rope 2 can be inserted and having threaded portions 60 a formed at both ends thereof, and the threaded portion 60 a is inserted into the rope supporting portion 60 by a nut 62.
And a support rope fixing portion 61 formed in a ring portion to which the support rope 5 can be connected on both sides of the connection base 63. According to the connecting member 6, the attachment and detachment to the rope 2 and the adjustment of the mounting position can be easily performed by adjusting the tension of the nut 62 similarly to the conventional rope clip, and the supporting ropes are provided on both sides of the connecting base 63. Since the fixing portion 61 is integrally provided symmetrically,
The supporting rope 5 provided on the fixture 3 stably positions and installs the covering slope 1 in a state of being grounded, and can easily support the rope 2 along a desired state, and has a simple and compact structure. Therefore, there is a feature that the connecting tool 6 having high rigidity and easy handling can be obtained.

Next, an embodiment of a supporting method using the working member supporting structure according to this embodiment will be described with reference to FIG. 1. In the example shown in FIG. Rope 2 with multiple attachments
Is wrapped around a standing tree planted on the top of the slope 1a or, in the illustrated example, on a standing tree or fixed object 12 fixed to the ground, and then the other end side is covered with the covering slope 1. And dropped. Next, with the worker wearing the lifeline 13 so as to be able to be extended to the body, while connecting to the fixed object 12 as described above and descending the covering slope 1,
The drainage holes 10 existing in the vicinity of each connecting member 6 on the right and left sides of the rope 2 are selected, and the fixing member 3 is inserted and fixed in the draining hole 10, and then the fixing member 3 and the connecting member 6 are supported. The ropes 5 are connected by the above-described connecting means.

At this time, the position of the water draining hole 10 in the vicinity of the connection with the connecting member 6 is selected in accordance with the uneven shape of the surface of the covering slope 1 and the like, and the covering slope work can be easily performed via the support rope 5. In this case, the rope 2 can be supported, and at this time, if necessary, the rope supporting portion 60 of the connecting tool 6 is operated to adjust the positioning in the vertical direction, so that the rope 2 is positioned on the left and right sides as shown in FIG. When the rope 2 is supported from the plurality of drain holes 10 through the fixture 3 and the support rope 5 in a substantially uniform tightening state on the left and right sides, the rope 2 is brought into a substantially hanging posture with the rope 2 as close to the covering slope 1 as possible. The support can be stably provided along the side, and the work of the covering surface can be easily performed.

Further, the method of supporting the rope 2 by using the drain hole 10 located on the side in the middle of the rope 2 makes it possible to form a mortar spraying section, which is greatly protruded in the middle of the covering slope 1, that is, an over-mold. When the hang portion 1b or the like is present, the connecting tool 6 is positioned on, for example, a concave surface formed above and below the top of the overhanging portion 1b and supports the connecting tool 6. The right and left drain holes 10 to be pressed and contacted to the covering slope 1 side via the rope 5 are selected, and the fixing tool 3 is attached and fixed to the drain holes 10 to cover the rope 2 above and below the overhang portion 1b. Face 1
Since it can be installed close to the rope 2 without leaving a large distance from it, there is a feature that it is possible to eliminate the difficulty of work due to a large bending of the rope 2 or unstable swing.

Therefore, the rope 2 supported along the covering slope 1 in this manner is stable on the covering slope 1 when an operator grips the rope 2 and moves up and down (elevates). Since the rope 2 is closely fixed, the lifting and lowering operation using the rope 2 as a guide member can be performed easily and easily.
The support rope 5, which is stretched and fixed to the side of the rope 2 in a tension state, can be effectively used as a scaffold for grasping, ascending and descending, and for covering work. Further, a plurality of ladder-like scaffolding bases 20 serving as lifting aids at the time of elevating can be detachably attached to the rope 2 supported side by side as described above. There is an advantage that the lifting and lowering work and the covering surface work, etc., utilizing the method can be efficiently and safely performed.

Next, a method and structure for supporting a working member according to a second embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. The description of the same configuration and method as those of the above embodiment will be omitted. According to this supporting method, the rope 2 extending along the covering slope 1 is fixed to the drainage hole 10 and can be fixed in the above-described drainage hole 10. A connecting rope 6a for restricting and supporting deflection in the left-right direction is connected to the covering slope 1 by movably supporting the rope 2 movably along the length direction while movably supporting the rope 2 movably in the length direction. Like that.

FIG. 8 shows an embodiment of the connecting member 6a in this case.
With reference to FIG. 2, the connecting tool 6a
U-shaped attachments 67, 67 each having a support shaft 65 and a screw rod 66 separately provided on the left and right of the center thereof, and an inverted U-shaped attachment from above. The rope support portion 60 is rotatably supported on the support shaft 65 and can be opened and closed with the support rope fixing portion 61 by attaching and detaching the screw rod 66. Therefore, since the connecting tool 6a also has the rope supporting portion 60 provided at the center portion and the supporting rope fixing portion 61 is integrally formed symmetrically in the left-right direction.
The connector 6a can be used in any direction without restricting the orientation, and has a simple, inexpensive, and compact structure, and is easy to handle and has high reliability.

The connecting tool 6a constructed as described above is stably positioned and supported on the covering slope 1 by the support rope fixing portions 61 on both sides having the support rope 5 attached thereto. When the support part 60 is disengaged from the screw rod 66 and is opened around the support shaft 65, the inside of the fixture can be opened. After the rope 2 is installed from above in the open part, the rope support part 60 is closed and the screw is closed. Rod 66
When the rope 2 is closed and fixed, the rope 2 can flexibly support the middle part thereof so as to be freely movable in the length direction, and can perform the restricting support in which the rope 2 is prevented from swaying in the left-right direction, and also cover the plurality of connecting tools 6a in advance. In a state where the rope 2 is installed on the slope 1, there is an advantage that the rope 2 can be easily stretched and detached at any time.

In this embodiment, as shown in FIG. 1 and FIG. 7, the rope 2 is not wound around and supported by, for example, a pulley 15 fixed to a fixed object 12 on the upper side of the slope 1a.
One side of the folded back is connected to an elevating mechanism installed on the flat ground below the covering slope 1, that is, in the illustrated example, is windably connected to a winding drum 17 of an appropriate winch device 16 so as to be able to be fed out.
By connecting and supporting the other end to the covering slope working machine 7, the operation of the winch device 16 allows the covering slope working machine 7 to be raised and lowered. The winch device 16
It is preferable to provide a rope guide mechanism 8 for smoothly guiding the rope 2 to the winding drum 17 on the side covering slope 1. At this time, the rope 2 has a plurality of connecting tools 6a arranged at appropriate positions in the vertical movement position, and selects the draining holes 10 near the connecting tools 6a as in the case of the connecting tool 6 described above. From the fixed fixture 3 fixed, it is positioned and attached and supported by a plurality of support ropes 5.

In the method as described above, the covering slope working machine 7 is previously wound up to the uppermost position of the covering slope 1 by the winch device 16 and the rope 2 thereof.
When the rope 2 is sequentially drawn out and the slope work is performed while the covering slope working machine 7 as described later is lowered, the dismantling work and the like can be performed easily and efficiently in a good procedure. Then, in the covering slope 1 on which the slope has been worked with the progress of the work, when the folded two ropes 2 are taken out from the corresponding connecting parts 6a with the rope supporting portion 60 opened, the covering method is performed. When the surface work machine 7 can be moved without being hindered by the connecting tool 6a, and after passing through the covering slope work machine 7, the rope 2 is installed and the rope support 60 is closed again. The connecting tool 6a can appropriately regulate the run-out of the rope 2 and the covering slope working machine 7 while freely moving the rope 2 accompanying the operation of the winch device 16, and can facilitate a stable slope work. There are advantages.

Next, with reference to FIGS. 9 and 10, an embodiment of a covering slope working machine 7 for performing a cutting operation and a crushing operation will be described as one mode of the above-described slope operation. A covering slope working machine 7 shown in FIG. 9 shows a cutter apparatus for moving a rotating disk-shaped cutter 70 to cut the covering slope 1 to form a cut groove 1c. The cutter apparatus 7 has a hollow box shape. A plurality of wheels 72 capable of running smoothly across the connecting member 6a are provided on the machine frame 71, and a connecting member 71a for detachably connecting the rope 2 is provided before and after the connecting member 6a. A cutter support 74 that pivotally supports the drive transmission case 73 and a rope support 75 that inserts and supports one of the folded ropes 2 are mounted so as to be freely attachable, detachable and attachable. I have. Reference numeral 73a denotes an operation lever for driving and operating the cutter 70 as desired, and 73b denotes a drive motor for the cutter 70.

Further, as shown in FIG.
The other end of the rope 2 connected to the connecting tool 71a is wound up and connected to the winch device 16 so as to be able to be fed out, and an intermediate portion of the rope 2 is supported by the pulley 15 from above the slope 1a in a folded state, and the rope support portion is provided. The rope 2 is inserted through 75 from the winch device 16 side, and the airframe is pressed against the coating slope 1 side by the weight and tension of the rope 2 at this portion.
Accordingly, the slope operation by the cutter device 7 is performed by rotating the cutter 70 while sequentially pulling out and lowering the rope 2 from a state where the rope 2 has previously been wound up to the uppermost position of the covering slope 1, and When the drive transmission case 73 is rotated downward with the cutter support 74 as a fulcrum, the entire thickness of the covering slope 1 in the vertical direction along the ropes 2 is sequentially and continuously cut, and the cut groove 1c is easily and accurately formed. Can be formed.

In this cutting operation, the cutter device 7 maintains the cutting posture via the wheels 72 and the machine frame 71 without manually carrying and operating a heavy cutter device as in the conventional cutting operation method. At the same time, the rope 2 connected to the winch device 16 is movably supported while preventing the rope 2 from dropping, so that the operator can concentrate on the cutting operation of the cutter 70 and perform appropriate cutting of the covering slope 1. It can be performed easily and efficiently. In addition, since the cutter device 7 has a work method of pressing and supporting the machine body from below the covering slope 1 with the rope 2 stretched on the pulley 15, the recoil at the time of cutting can be suppressed by the rope 2. In addition, when the cutter device 7 is located in the concave portion of the overhang portion 1b, there is an advantage that separation of the cutter device 7 or large lifting can be suppressed by the pressing action of the rope 2.

The rope 2 has water drain holes 10 on both sides thereof.
Since the connecting tool 6a is supported from the plurality of fixing tools 3 fixed to the above via the supporting rope 5, and the connecting tool 6a flexibly supports the rope 2 so that the rope 2 can be inserted and removed and can be moved. In the cutting operation as described above, when the cutter device 7 reaches the connecting tool 6a due to the movement, the rope supporting portion 60 of the connecting tool 6a is opened as described above to release the support of the rope 2 installed therein. Then, the cutter device 7 can be freely moved, and after the cutter device 7 is moved and passed, the ropes 2 can be supported again in a flexible manner and stably supported by the connecting tool 6a. .

Next, the coated slope 1 shown in FIG.
An embodiment of the crushing machine 7 that is hit and destroyed by 6 will be described. The crusher 7 has a chisel 76 connected to a compressor (not shown) installed on the ground through a conduit 77a.
Is mounted and supported on a universal support frame 78 having wheels 72 so as to be able to move up and down and rotate. The free support frame 78 rotatably supports two divided wheels 72, 72 on a support shaft 79.
In a state where the rope 2 is interposed between the shafts 2 and 72 in a sandwiching manner on the support shaft 79, one of the wheels 72 is provided so as to be movable in the axial direction, so that the movement of the crushing working machine 7 which clamps and fixes the rope 2. Can be switched between a stop posture in which the rope 2 is fixed and a movable posture in which the rope 2 is not pinched.

Further, the universal support frame 78 forms a breaker guide 78a which mounts and supports the mounting portion 77b of the breaker 77 so as to be slidable in the vertical direction and rotatable. In this state, the crushing operation can be easily performed in a desired posture while stably supporting the breaker 77. Accordingly, the crushing machine 7 having the above configuration has a simple and compact configuration in which the breaker 77 is directly provided on the wheel 72 via the universal support frame 78, so that the weight of the aircraft can be reduced, and the coating method can be reduced. Even when the rope 2 is stretched on the surface 1 without moving, the crushing machine 7 can be easily moved and transported by using the rope 2 as a work guide, and the breaker 77 fixes and supports the machine body to the rope 2. In this state, it is supported so as to be vertically and pivotally operable, so that it can be operated with a suitable posture adapted to the situation of the covering slope 1, and the crushing operation can be performed efficiently and easily. Also in this case, when the crushing machine 7 is supported by the rope 2 as shown in the illustrated example, it is possible to easily perform the work in which the recoil during the crushing work is suppressed.

The covering slope working machine 7 capable of performing the covering slope working method supported on the rope 2 as described above is
Without limitation to the above, for example, a work machine that can perform work such as removal of a deteriorated portion of an existing structure, and that can perform cutting and cutting work by a water jet method, and may be a mortar and concrete The cracking and peeling of the structure can be similarly applied to a working machine that repairs and reinforces by injecting or applying the same member or synthetic resin. Further, the crushing work machine 7 may be a hitting device capable of switching between driving and vibration breaking by hydraulic pressure, and the above-described covering slope working machine 7 is provided with various sensors, and is operated by remote control operation or screen visual recognition.
