Description

High slope Revetment block integration structure using pipe}

Embankments or embankments are formed on beaches, riversides, and lakesides, and these embankments or embankments are naturally formed and artificially formed to prevent flooding of seawater or river water. One side or both sides of the embankment or embankment is formed as a slope, eroded by running water (sea water, river water, rainwater, etc.), the soil, sand, gravel, etc. may be lost, thereby weakening as a whole. In order to protect the banks and dams from erosion caused by running water, the workpieces installed on the slopes are called revetment facilities. A revetment block is installed on the slopes by paving the slopes continuously. It is the most representative lakeside facility.

The raft block may be seated on the slope by its own weight, but the raft block may be lost due to the erosion of a portion of the slope, and measures for the loss of the raft block have been taken. As a countermeasure against the loss of a raft block, a connecting ring is embedded in a chamfered edge of the raft block, and the link chain is tied to the link chain at a portion where the four raft blocks face each other. 1)), a method of totally integrating a plurality of revetment blocks by inter-locking (see [Ref. 2]), a method of using a connection chain and a method of interlocking between blocks ([Reference] 3), a method of integrating a plurality of raft block, such as a method of fastening the adjacent raft block with a fastener (not shown) is widely used.

[Reference Figure 1]

[Reference Figure 2]

[Reference Figure 3]

The above integration method between the revetment blocks has the effect on the individual loss of the revetment blocks, but it can not dispel the concern that the revetment blocks can slide down on the steep slope. 둔) It could not be expected that stabilization ground stabilization effect could be expected by just doing it.

Japanese Laid-Open Patent Publication No. 11-315526, which can be considered as an existing technique for solving this problem, relates to a method of connecting concrete blocks, and Japanese Patent Laid-Open No. 10-114928 discloses a plurality of concrete blocks for protecting a surface. The present invention relates to a method of connecting a concrete block for preventing corrosion of the connecting member together with strongly connecting the blocks by connecting the connected concrete blocks with simple brackets.

In the existing technology, while inserting a deformed reinforcing bar in the space between the blocks while tightening the connected blocks to prevent the sliding block of the overall relief. However, it is difficult to prevent the reinforcing block structure from weakening the shear reinforcement of the deformed rebar due to the cracking of the concrete or the ground weakening over time. Particularly, when the cracks in concrete are generated on steep slopes, the smaller the cross-sectional specific gravity of the deformed rebar, the weaker the bearing capacity, so that it cannot support the load of the entire revetment block. In particular, the integrated structure between the revetment block has been proposed in the existing technology, but the deformed rebar is inserted separately for shear resistance, so the integration of the deformed rebar may be problematic. Furthermore, due to the drawing of deformed reinforcing bars, there is a risk of the entire surface destruction caused by unification of the banks connected by integration. Therefore, it is necessary to develop a new structure for shear reinforcement of the banks.

1. Japanese Patent Laid-Open No. 11-315526 (1999.11.16) 2. Japanese Patent Laid-Open No. 10-114928 (1998.05.06)

In order to solve the above problems, in the present invention, while forming a connection structure between the revetment blocks in the steep slope, while reinforcing the shear to solve the problem of sliding of the relieving block as a whole, a certain thickness of the reinforcing bar to prevent surface destruction To provide a configuration to improve the bearing capacity by inserting a steel pipe having an inner diameter and an outer diameter of.

In particular, it is an object of the present invention to provide a connection structure for integrating a steel pipe with a revetment block installed on a steep slope so as not to be drawn out due to corrosion and concrete cracking over time.

The present invention is continuously arranged vertically and horizontally to cover the top surface of the steep slope of the slope slope 45 degrees or more and 73.3 degrees or less, each corner portion chamfering (chamfering) treated revetment block; A space portion formed by a combination of four corner portions of the adjacent shore bank; A steel pipe installed at the center of the space part, the lower part of which is inserted into the inclined ground, and the upper outer periphery is formed so that two through holes face each other; Connecting edges embedded in each corner portion of the revetment block are exposed to the space portion, the connecting chains being fastened in an annular shape by turning the inside of each of the connecting rings; A fastener of a length member penetrating both through holes of the steel pipe to connect the connection chain to the steel pipe; And concrete poured and cured in the space portion, wherein the rake block, the steel pipe, and the connection chain are cast and cured in a state in which the fastening block is integrated with the fastener so that the bearing strength is improved. Provide an integrated structure.

The present invention has the following effects.

1. Shear resistance is improved by installing steel pipes with wider cross-sectional area than deformed reinforcing bars in the space for shear reinforcement of revetment block structure, and improve the bearing capacity of revetment block as concrete is poured and cured into steel pipes. The stability of the revetment is improved because the revetment block slips and is not separated from the slope.

2. In particular, it is possible to reinforce the integrity between the revetment block and the steel pipe at the same time to form the unity between the revetment block by the link and the chain of the present invention. As a result, unlike conventional deformed reinforcing bars, the risk of drawing out steel pipes with weak surface friction is eliminated through the unique shape structure of the steel pipes and the connection components with the revetment block.

3. In addition, the steel pipes penetrated into the sloped ground function like grouted soil nails to strengthen the shear stress of the ground.

4. Meanwhile, in the structure integrated as a whole, the stability of the inclined ground can be strengthened by utilizing the self-weight of the revetment block as a force for pressing the inclined ground.

Provides a surface protection block integrated structure.

In another aspect, the present invention provides a steel pipe with a steep slope ophthalmic block integrated structure characterized in that the inner diameter is 10mm or more and 50mm or less, the outer diameter is 22mm or more and 60mm or less, the length is 0.4m or more and 1.5m or less.

1 is a cross-sectional view of a steep slope revetment block integrated structure according to the present invention. Hereinafter, with reference to [1] will be described in detail the features of the present invention according to the components of the present invention.

The present invention is configured so that the rake block 10 is arranged continuously and vertically covering the upper surface of the steep slope of the slope slope 45 degrees or more and 73.3 degrees or less. The slope inclination means the angle between the bottom surface and the slope surface, and when the bottom surface is a horizontal plane, the ratio of the horizontal plane to the vertical plane corresponds to 1: 1 to 0.3: 1.

The revetment block 10 is not particularly limited in shape and material, but each corner 11 is chamfered (chamfered) treatment. The revetment block 10 is inclined by the root of the vegetation (2) by forming a vegetation (2) vegetation inside the retreat block 10 by forming a hollow vegetation part in addition to the chamfered corner (11) The binding force on soil loss of the ground (1) can be strengthened.

In the case of continuously arranging the rake block 10 vertically and horizontally on a steep slope, a space portion 20 is formed by a combination of four edge portions 11 adjacent to the rake block 10. That is, the space portion 20 is formed at each point where four banks of the banks 10 arranged in succession on the inclined ground (1) gather.

The steel pipes 30 are installed in the center of the space portion 20 formed by the rake block 10, and then the concrete 40 is poured into the space portion 20 and cured to fix the steel pipe on the inclined slope. . Concrete 40 that is poured and cured in the space portion 20 may be selectively applied to concrete, concrete concrete for general concrete, as well as environmentally friendly ocher concrete, pore concrete capable of botanical plants.

In general, when the slope is less than 45 degrees, the shear strength received by the lowermost rake block corresponds to about 20% of the compressive strength, so that the shear resistance of the lowermost rake block is sufficient, so that it can be separated and removed without installing the steel pipe of the present invention. You can stop it. However, since the shear resistance is sharply lowered at steep slopes of 45 degrees or more, a reinforcement for reinforcing horizontal forces such as a nail nail or an anchor is required. In the present invention, as a reinforcing material to be used in a steep slope in the range of slope inclination of 45 degrees or more and 73.3 degrees or less, a steel pipe form is used instead of a deformed reinforcing bar.

The steel pipe has a wider cross-sectional area than a deformed steel bar. Since the cross-sectional area of the steel pipe is wider than the cross-sectional area of the deformed reinforcing bar, it is possible to improve the shear stress of the entire revetment block.

[Reference Figure 4]

[Reference Figure 4] is a real picture of the deformed reinforcing bars generally used. As described above, when the diameter of the deformed reinforcing bar is applied to the present invention to increase the cross-sectional area, the reinforcing material is much consumed, the cost burden is large, and the deformed reinforcing bar becomes heavy, and mobility and installation ease of inferiority. On the other hand, when installed as the steel pipe 30 can be manufactured to have a larger cross-sectional area than the general deformed reinforcement by increasing the diameter, it is possible to form a load similar to the deformed reinforcement while the interior is filled with concrete poured into the steel pipe.

In particular, the inner diameter of the steel pipe is 10mm or more and 50mm or less and the outer diameter is 22mm or more and 60mm or less to satisfy a predetermined thickness or more. That is, the thickness of the steel pipe may be 6mm to 25mm. Since the thickness forms a value similar to the diameter of the deformed steel bars (generally 6.35 mm, which is D6), it ensures a bearing force similar to that when the conventional deformed steel bars (D6) are installed in the thickness portion, so that a plurality of steel pipes can be installed in one steel pipe. It has the same effect as installing two deformed bars.

[Reference Figure 5]

In the case of installing a plurality of deformed bars as shown in [b] (b), the cost reduction is not only achieved by installing one deformed bar having the same cross-sectional area, but also the shear resistance is improved while the buckling strength becomes stronger. High efficiency The steel pipe may have an effect of installing a plurality of deformed steel bars as shown in (b) of (a) of FIG. 5.

In addition, the length of the steel pipe is preferably 0.4m or more and 1.5m or less, if the length of the steel pipe is less than 0.4m the length is inserted into the steep slope is 0.3m to 0.35m to be integrated with the revetment block integrated with the steel pipe This is because it is difficult to exert a tensile force to adhere to the inclined slope. On the other hand, when the length of the steel pipe is more than 1.5m, it is not easy to insert the inside of the steep slope. This is because the installation of the nail or anchor is essential to the installation of the drill, whereas when the retaining wall is installed on the steep slope, the drilling is easy and generally inserted in a type method. In particular, the buckling tends to occur in the insertion of the deformed reinforcing bar type, whereas the steel pipe 30 is stronger in the buckling than the deformed reinforcing bar.

In particular, the steel pipe 30 of the present invention, unlike the deformed rebar, the outer surface is smooth and the surface friction force is lower than the deformed rebar, there is a risk of drawing. This problem is solved through the connection structure of the connecting ring 12 and the connecting chain 50 or fastener 60 of the revetment block. FIG. 4 is a cross-sectional view of an embodiment of a steel pipe having a steep slope revetment block integrated structure according to the present invention. Referring to this, it can be seen two embodiments of the steel pipe presented in the present invention.

The first is a steel pipe form (first embodiment) formed at the center of the space portion, the lower portion of which is inserted into the inclined ground and the two outer holes 31 are opposed to the upper outer circumference. This is introduced in [Technology as Background of the Invention] in addition to the "steel pipe 30 inserted into the center of the space portion 20" and "concrete 40 filled in the space portion 20" which is a key component of the present invention. A synergistic effect is achieved by organically applying a "method of tying the linking ring to the linking chain at the site where the four revetment blocks face each other" (see reference 1). That is, since the connecting ring 12 is embedded in each corner 11 of the chamfering (chamfered) revetment block 10, four connecting rings 12 are exposed in the space 20. The linear connecting chain 50 is turned inside each of the four connecting rings 12 and the ends thereof are fastened to form an annular shape as a whole, and the steel pipe 30 and the connecting chain 50 are connected to each other. By connecting to the fastener 60 penetrating through the through-hole 31 of the steel pipe, it is to strengthen the integrity between the guard block 10 and the integrity between the guard block 10 and the steel pipe (30).

An embodiment (first embodiment) of such a structure is shown in FIG. The first embodiment of the present invention is applied to the steel pipe as a steel pipe 30, the fastener 60 is configured to pass through the through hole 31 of the steel pipe 30 and both ends thereof are fastened with the connecting chain 50 will be. In addition, it can be seen that the through-hole 31 through which the fastener 60 can penetrate the steel pipe is formed through the cross-sectional view of the steel pipe of FIG.

Looking at the second embodiment of the second form of the steel pipe 30 proposed in the present invention, the outer ring of the steel pipe is formed so that the connecting ring 70 is coupled to the linear connection line 70 in four directions It can be confirmed in (b) of FIG. The steel pipe 30 is a steep slope improved by improving the bearing strength by the concrete ring is placed and cured in a state in which the connection ring 12, the corresponding connection chain 70 and the connection ring 32 of the steel pipe is integrated one-to-one in the integrated block. It forms a surface relief block integrated structure.

The integrated structure of the raft block 10 is also intended to reinforce the integrity between the raft block 10 and the steel pipe 30, the embodiment of the structure (second embodiment) is shown in FIG. In the second embodiment of the present invention, it can be seen that the corresponding connection chain 70 is coupled to the connection rings 12 and 32 of the steel pipe 30 and the revetment block 10. In this case, the connection ring 32 is connected to the steel pipe 30 instead of the through hole, thereby implementing integration with the revetment block through the corresponding connection chain 70.

As described above, in the present invention, the concrete 40 is inserted into the space portion 20 in a state in which the steel pipe 30 is inserted into each space portion 20 (preferably, in a state in which the steel pipe is inserted perpendicular to the inclined ground). By filling the rake block 10 disposed on the inclined ground (1) as a whole integrally, so that the raft block 10 is embedded in the inclined ground (1) as shown in FIG. A fixed structure is achieved, and as a result, only the guard block 10 may be lost unless the slope ground 1 itself collapses. In addition, by installing a steel pipe (30) having a larger cross-sectional area than a conventional deformed reinforcing bar to improve the bearing capacity, while strengthening the shear resistance and at the same time to form a through-hole or connecting ring in the steel pipe to prevent the independent drawing of the integrated reinforcement block Form the structure will be able to stably fix the raft block 10 in the steep slope.

In particular, by injecting the steel pipe 30 deeply into the inclined ground (1) can play a role of a reinforcing material to strengthen the shear stress of the inclined ground (1), such as a nail (soil nail), on the other hand the present invention 30 may be interpreted as a structure that transmits the self-weight of the rake block 10 integrated entirely on the outer surface of the inclined ground 1 as a compressive force for stabilizing the inclined ground 1. This uses the inverse structure of the earth anchor structure, which transfers the tensile force applied to the undercarriage (fixed place) where the strand is settled on the ground as the stabilizing force on the inclined ground (1). The bearing capacity of the steel pipe contributes to the stabilization of the overall retaining wall block structure.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. Therefore, the claims of the present invention include modifications and variations that fall within the true scope of the invention.
