BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block constituting a retaining wall and a retaining wall planting block for strengthening the retaining wall in a retaining wall for preventing the collapse of the ground caused by the steep slope of the ground.

As there are many mountainous areas in Korea, there are many areas where the retaining wall should be installed, so there are many existing retaining blocks.

Regarding the conventional retaining wall construction block and its construction method, the "retaining wall planter block" registered on May 25, 2001 (hereinafter referred to as 'prior art 1', registered 20-0233310) and July 2004 2 "Building structure of block-type retaining wall and its construction method" (hereinafter referred to as "prior art 2", registered 10-0440091) registered in the work can be seen.

When constructing the retaining wall, it is essential to provide a drainage pipe to prevent the ground behind the retaining wall from collapsing by flooding.

However, in the conventional drainage method, it is common to discharge water to the outside by directly burying a drain pipe on the ground, which causes a problem of low efficiency of drainage. The prior art 1 improves the efficiency of drainage by connecting the drain pipe to the block, but this is for the purpose of providing water to the plant, and the drained water is trapped in the block, so that the area where the block comes into contact with the water is weakened. Can be imported.

The stacking form of the block is formed in the form of vertical stacking, stacking, stepped stacking, etc. Also, depending on the topography, it may be necessary to install retaining walls in a curved line. The construction of the retaining wall should strengthen the building capacity between the blocks to prevent misalignment and departure from the retaining wall. In addition, retaining wall construction needs to be easy.

Although the prior art 1 combines the support jaw, the reinforcement jaw, and the support pin between the upper and lower sides of the block to strengthen the construction force, it is disadvantageous that the retaining wall construction takes a lot of time because the upper and lower blocks must be connected with the support pin. In addition, in the prior art 1, retaining wall construction is possible in a curved area, but this is a combination of upper and lower blocks only when the vertical stacking or staggering type is used, and in the stair stacking, the upper and lower blocks are not combined, and thus, there is a weak building construction between blocks.

The prior art for the retaining wall construction method is a retaining wall when the means behind the retaining wall and the retaining wall are weakly bound, or the binding force is weak, so that the ground behind the retaining wall is thinned by rain water, or the ground behind the retaining wall has a large force applied to the retaining wall. There was this crashing or pushing issue.

In addition, in the related art 2, first, there is a problem in that the construction method is limited to the vertical stacking and the retaining wall construction is difficult in the curved area, and the drainage efficiency is lowered as described above. In addition to the block wall to form a separate shotcrete (shotcrete) layer to strengthen the bearing capacity of the block wall, but the disadvantages of the high cost and long construction period. On the other hand, the block wall and the shotcrete layer can be regarded as one retaining wall. In this case, the supporting reinforcement is formed to increase the binding force between the retaining wall and the ground behind the retaining wall, but the load of the ground is concentrated on the supporting reinforcement. Forming multiple support bars to disperse them is expensive and the construction period is long.

The present invention has been proposed to solve the problems of the conventional various retaining wall building blocks as described above and to build the retaining wall firmly,

It provides space for plants to grow on the retaining wall, enables the retaining wall to be constructed even in curved areas, not straight lines, and facilitates the retaining wall construction work, and improves the efficiency of drainage in the internal ground of the retaining wall, The purpose is to prevent the collapse and fall of the retaining wall by reinforcing the building capacity between blocks and strengthening the binding between the built retaining wall and the ground behind the retaining wall.

       Hollow part which is formed in the direction parallel to the direction of gravity in the constructed retaining wall to provide vegetation space, an installation hole penetrating from the front part exposed from the built retaining wall toward the rear part, and the gravity direction in the built retaining wall and the installation It characterized in that it comprises a main body including a concave indentation formed on both sides to be perpendicular to the ball forming direction, and a drain pipe inserted into the installation hole of the main body.

Retaining wall construction vegetation block according to the present invention is formed in a direction parallel to the direction of gravity in the retaining wall, the hollow portion to provide a vegetation space, the installation hole penetrating toward the rear portion from the front portion exposed from the built retaining wall, And a vegetation block formed at a predetermined height including a body including recesses formed on both sides of the retaining wall in a gravity direction and perpendicular to the installation hole forming direction, and a drain pipe inserted into the installation hole of the body. After that, the support rod is inserted into the hollow part of the main body, and the support rod is constructed by connecting the reinforcing member embedded in the retaining wall.

The body of the retaining wall construction vegetation block is generally made of concrete, but can be produced by loess or the like to fit the retaining wall installation site. As a preferred material, foamed concrete may be used. Foam concrete is a lightweight concrete that makes many bubbles in concrete without using fine aggregates. It has the advantages of excellent water absorption and dry shrinkage.

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

As shown in Fig. 1 and Fig. 2, the present invention relates to a block used in retaining wall construction, and includes a block body 10 and a drain pipe 20. The hollow portion 11 of the retaining wall building block body 10 according to the present invention is to allow the plant to naturally grow or artificially grow after the building of the retaining wall, and also as an insertion opening of the support rod 30 when the retaining wall is constructed. It is to be used. For reference, vegetation is also possible in portions formed by the recesses 13 of two adjacent blocks.

In the drawings, the hollow 11 has a rectangular shape, which is merely one example, and various shapes such as a circle, a triangle, a rhombus, and the like may be formed, and a plurality of the hollow parts 11 may be formed. By growing plants such as flowers or trees in the soil provided to the hollow body 11, not only can create aesthetic beauty, but also have a strong retaining wall due to the native plant roots.

As shown in FIGS. 1 and 2, the drain pipe 20 inserted into the installation hole 12 of the main body extends into the ground through which the hollow part 11, which is a vegetation space, is formed to form a retaining wall. Preferably, the drain pipe 20 configured as described above is intended to prevent the ground and the retaining wall from collapsing by applying an unusual force to the retaining wall by rainwater or the like submerging in the ground behind the retaining wall and diluting the ground. Although not shown in the figure, it would be desirable to add a filter net such as a wire mesh to the end of the drain pipe 20 buried in the ground so that soil, sand, gravel, etc. do not penetrate the drain pipe and hinder the flow of water.

The recessed part 13 formed on both sides of the main body facilitates the left and right movement of the front part 16a or the rear part 16b of the main body 10 when the retaining wall is not straight but curved, and the retaining wall construction of the operator is easy. It is for convenience of work. Since the front portion 16a of the main body is exposed to the outside, it is preferable to have a natural stone shape or a special shape.

A female coupling portion 14b or a male coupling portion 14a is formed in the bottom portion 17b and the top portion 17a of the main body, respectively, to prevent the block from being separated in the vertical direction with respect to the gravity direction in the constructed retaining wall. This prevents misalignment between the upper block and the lower block constructed by the coupling between them and prevents the block from leaving the retaining wall. Shapes of the coupling parts 14a and 14b may be various shapes such as protrusions, circular shapes, rectangular parallelepipeds, rectangular parallelepipeds, and female coupling parts 14b formed at symmetrical positions of the bottom face part 17b and the top face part 17a, The number of the water coupling portions 14a is one or more, and in general, four are suitable.

In the case of vertical stacking, the female coupling part 14b and the male coupling part 14a are coupled to each other by overlapping the upper surface part 17a and the bottom surface part 17b of the upper and lower blocks. In the case of stair stacking, the female coupling part 14b and the male coupling part 14a of the rear part 16b of the lower block and the front part 16a of the upper block are coupled. In the case of stacking, the female coupling part 14b or the male coupling part 14a in the upper surface part 17a of the lower left block and the lower right block is the female coupling part 14b or the male in the upper bottom part 17b. Coupling to the engaging portion 14a.

The cross-sectional area of the female coupling portion 14b should be somewhat larger than the cross-sectional area of the male coupling portion 14a, which is advantageous for various types of retaining wall construction.

 In addition, in order to prevent the stacking of blocks by the reinforcing member 40 from the bottom surface portion 17b or the upper surface portion 17a of the main body 10 by the reinforcing member 40, that is, the reinforcing member 40 The hollow part of the block body 10 so that the support rod 30 and the pillar member 50 are firmly connected by passing through the two main bodies 10 without being interfered by the two main bodies 10 stacked up and down. Reinforcing member grooves 15 are formed in the upper surface portion 17a or the lower surface portion 17b of the main body in the direction of the rear portion with the drainage pipe 20 in both of them, and the connection path of the reinforcing member 40 is made in (11). It is desirable to give.

When the installation area of the retaining wall is curved rather than a straight line, the retaining wall can be constructed by varying the widths of the front portion 16a and the rear portion 16b of the main body 10. If the curve is convex, the width of the front portion 16a should be widened. If the curve is concave, the width of the front portion 16a should be narrowed.

In order to build the retaining wall, the blocks are first stacked vertically with a certain height. After lamination, the supporting rod 30 is inserted into the hollow portion 11 of the main body 10. The support rod 30 is preferably embedded in the support base of the retaining wall. After insertion of the support rod 30, the reinforcing member 40 is embedded in the ground behind the retaining wall and the retaining wall by connecting the reinforcing member 40 to the supporting rod 30 to counteract the force applied to the retaining wall by the ground behind the retaining wall. The reinforcing member 40 is preferably a wire rope, but can be used in addition to a variety of rebars, ropes. In addition, the reinforcing member 40 may be formed with resistance protrusions 41 against the force acting perpendicular to the direction of gravity, that is, the collapse force of the ground behind the retaining wall acts on the retaining wall. The resistance protrusion 41 may have various shapes such as a barb shape, a V shape, and a rod shape.

In order to secure the retaining wall, the column member 50 is installed on the opposite side of the block, that is, on the ground behind the retaining wall, horizontally with respect to the direction of gravity, and the reinforcing member 40 is connected to the pillar member 50. Connect to At this time, the end of the reinforcing member 40 connected to the pillar member 50 and the support rod 30 is preferably finished by a clip or the like so as not to be released. In addition, one or more reinforcing members 40 are connected to the supporting rods 30 in the stacked blocks.

Retaining wall construction method is not only a vertical stacking method as described above, but also a stair stacking and stacking. However, the construction method by stacking step by step requires a pillar member 50 and the support rod 30 and the reinforcing member 40, and the construction method by stacking the support rod hollow portion 11 of the main body 10 And inserted through the concave inlet 13 are only different.

As described above, the retaining wall construction vegetation block of the present invention forms a hollow portion in the main body to allow plants to grow in the soil provided therein, thereby creating an aesthetic and beautiful effect, and the upper and lower surfaces of the block main body. The female coupling part and the male coupling part are formed in the part to facilitate the construction work between the upper and lower blocks by the mutual coupling thereof, and the retaining wall is firm by increasing the mutual building ability between the blocks.

In addition, the width of the front and rear parts of the block body is different so that the retaining wall can be installed even when the retaining wall is not a straight line, and the recesses on both sides of the main body are formed to allow the operator to handle the block when building the retaining wall. It is easy.                     

In addition, the water discharge in the ground behind the retaining wall by the drain pipe of the block is excellent, inserting a support rod in parallel to the direction of gravity in the block body hollow in the constructed retaining wall and connecting the reinforcing member formed with a resistance protrusion on the support rod By adopting the method, the construction method is simple, the construction cost is low and the work is easy, but the binding force between the retaining wall and the retaining wall is excellent so that the ground and retaining wall do not collapse, and the retaining wall is pushed by the force behind the retaining wall to the retaining wall. It is effective to prevent it.

In the above description of the present invention with reference to the accompanying drawings, the retaining wall for planting blocks having a specific shape and structure and the method for building the same, but the present invention can be variously modified and changed by those skilled in the art, such variations and Changes should be construed as falling within the protection scope of the present invention.
