f) The backfilling process is a process of backfilling with high quality soil between the back surface of the retaining wall and the cut slope. Typically, this process is to fill the sand and gravel, etc. In the present invention, the plants planted inside the vegetation block 150 is backfilled with high quality soil to provide an environment that can grow better. That is, the plant planted inside the vegetation block 150 may be rooted in a good quality earth and sand filled through a nail hole or a communication hole formed on the rear surface, or may consume more nutrients than a limited space.

And, g) the water supply pipe installation process, if you want to cultivate the plant using the vegetation block 150 constructed by the retaining wall, by installing a water supply pipe 172 to supply water evenly to the cultivated plant, f) It may be installed before the process or at the same time. As shown in FIG. 7, a U-shaped side opening 170 capable of inducing and discharging rainwater to both sides is installed at an upper rear surface of the installed retaining wall, and a water supply pipe 172 is installed at the rear of the retaining wall.

Meanwhile, as shown in FIG. 13, the U-shaped side opening 170 is installed to block a large amount of rainwater from being introduced into the earth and sand, but at the same time, one side is connected to the water supply pipe 172 to connect U. Rain water collected in the mold side opening 170 may be introduced into the water supply pipe 172 to supply water to the planted plant.

In any case, the water supply pipe 172 is arranged in a checkerboard shape at the rear of the retaining wall, and as shown in FIG. 10, the spray holes 174 are disposed at regular intervals in a portion located in the vegetation hole formed in the vegetation block 150. Formed to supply the water or nutrients supplied from the upper portion of the water supply pipe 172 to the planted plant has an advantage that can provide an environment that is beneficial to vegetation. At this time, the outer periphery of the water supply pipe 172 is provided with a geotextile 154 to prevent the blockage of the spray hole 174 due to the soil.

In addition, the lower end of the vertical pipe is also blocked to supply water into the vegetation block 150 installed at the lower portion of the water supply pipe 172, and both ends of the horizontal pipe are also blocked. And usually, the uppermost part of the water supply pipe is blocked by an unsigned cap.

Finally, h) the hole pipe installation process is a process to discharge the rainwater and ground water introduced into the backfilled soil during the process to implement the stabilization of the construction state, together with the backfilling process In parallel. In addition, as can be seen in Figures 7 to 9, the hole tube 180 is buried in the middle of the earth to be filled back, the hole tube 180, as shown in Figure 10, the nail is not inserted into the nail It is inserted through the nail hole 102 formed in the front of the block 100. At this time, the lower part where the hole tube 180 is installed is in a back-filled state, and after the hole tube 180 is installed, the back hole is filled as much as the height of the block or the block is stacked. Such, the perforated pipe 180 is already known, as can be seen in Figure 10 is formed with a plurality of inlet holes on the upper surface, the rainwater or groundwater introduced into the inlet hole is the front of the nail hole 102 of the nail block 100 Is discharged. In addition, the outer periphery of the perforated pipe 180 is provided with a geotextile 154 to prevent clogging of the inlet hole like the water supply pipe 172. On the other hand, the cap 177 is inserted into the nail hole 102 of the nail block 100 to improve the beauty by concealing the end of the inserted hole tube 180. Of course, although not shown in front of the cap 177, a plurality of small holes are formed to discharge the water.

At this time, the groove is formed at the bottom of the inner wall of the front of the block to be built on the upper end after fastening the bracket (B) by bolting in advance to the bolt hole formed in the upper end of the rear inner wall of the block built on the bottom before the block construction on the top The bolt bolt of the negative portion is bolted to match the position and the bracket (B) fastened to the bottom block.
Inside the stacked basic block 140 is filled with good quality soil and planting small trees in the interior space. The reason for laminating the block is to plant trees such as small trees in the empty space of the block.In the existing vegetation hall, plants such as vines can be planted, but trees are difficult to grow. This is to create an environment that grows in general benches by exposing to the outside of the interior space.

Then, the lower anchor block 10 and the nail block 100, the upper basic block 140 by connecting the back, and laminated. Of course, here, too, the anchor block 10 and the nail block 100 may be installed alternately to install the anchor 50 and the nail body 106, and only the nail block 100 or the anchor block 10 to install the nail body Of course, only 106 may be installed.

Thus, by planting the tree in the empty space of the basic block 140, the cap 177 or anchor head (anchor cap is covered) and the plate support that is exposed to the front of the retaining wall and the upper layer of the tree (such as branches and leaves) It is beautiful and is eco-friendly by aesthetic appearance.

      And, when forming the multi-stage by the rear-recession, if the pedestal 160 is installed on the rear of the lower block to stabilize the unstable support structure of the lower part, the bottom of the upper block is positioned above the pedestal 160, wherein the pedestal Since the block 160 is not fastened to the upper block 160 and the structure is placed on the pedestal 160, it is preferable to connect the rear inner wall of the block and the pedestal 160 by installing an L-shaped angle in order to connect more closely. 16 is an enlarged view of the bracket coupling portion, the U-shaped bolt is inserted into the mounting hole formed at the rear of the block, and the bolting hole formed in the pedestal 160 and the U-shaped bolt are connected and fixed with nuts. do. On the upper surface of the pedestal 160, in which the rear portion of the block is stacked, a hole for bolting is formed when the L-type angle is installed, and the bolt is coupled to the L-type angle.

In addition, when forming the multi-stage by the above-mentioned back stitching, as shown in Figure 16 during the filling can be fixed through the geogrid instead of fixing the block through a nail or an anchor. How to use this geogrid will be described below (Fig. 21).

On the other hand, it is preferable that the basic block is embossed and embossed on the front surface to eliminate boredom of the front, and at the same time maximize the beauty.

Referring to FIG. Laminated by as much as possible. This has the advantage of providing a new feeling retaining wall as well as eliminating the boredom because the front surface has a stepped shape. At this time, the stacked blocks are fixed through the geogrid 190 during the fill, as shown in Figure 22, as shown in Figure 23, can be fixed through the nail 106 and the anchor 50 in the cut surface.

      On the other hand, the stacking method of the blocks is the same as the general retaining wall, so a separate description will be omitted, but since the blocks stacked on the upper part is seized by a certain distance, as shown in some enlarged view, the coupling part of the inner surface of the block It can be seen that the formed recesses 24 do not have the same verticality with each other. That is, since the recess 24 of the block stacked on the upper side is moved backward than the recess 24 of the block on the lower side, the recess 24 may not maintain the same verticality, and thus the fastening using the bracket B may not be smooth. Therefore, the auxiliary bracket 200 is inserted into this gap to induce a smooth fastening of the bracket (B).
