  Since both the above-mentioned Patent Document 1 and the box-type retaining wall are filled with a large amount of crushed stone on the back surface, safety against earth pressure and earthquake is ensured, but water supply from the back surface is cut off. Replenishment due to rainfall and moisture in the air is not sufficient, and plants often die when the weather continues. It is widely known that moisture is the lifeline of living organisms, not to mention specific examples.

  In order to solve the above-described problems, the present application has a structure in which crushed stone is not used on the back surface. Moreover, safety against earth pressure and earthquakes was ensured. Due to the relationship between the planting soil that supports the growth of the plant and the soil on the back, the redistribution phenomenon of water in the soil is directly connected through the opening on the back of the concrete block without interposing a crushed stone layer between them (non-patent literature) 1)), water is supplied, and the roots of plants grow through this connected soil. To secure safety against earth pressure and earthquakes, in the case of high embankments, anchors were attached to concrete blocks and settled in the soil on the back. We dealt with earthquake motion in the direction perpendicular to the anchor. The method is based on earthquake-resistant connected concrete. Specifically, it is shown in the examples. In addition, there is a risk of subsidence because the concrete block is installed not on the crushed stone layer but on the backside earth and sand. Therefore, after excavating the earth and sand before installing the first-stage concrete block, it is squeezed well, put chestnut stone, and further squeezed. In the second and subsequent steps, the bottom of this block is placed on the rear end of the block in the lower step, and the latter is placed on the compacted back soil. The backside earth and sand should be of good quality and rolling should be done every 20-30cm.

  When installing concrete blocks in a staircase pattern as a method of greening the concrete wall, the structure does not use crushed stone on the back, and the relationship between the planting soil that supports the growth of plants and the soil on the back does not sandwich a crushed stone layer between them. In order to ensure that the planting soil in the block and the soil on the back are directly connected through the opening on the back of the concrete block and are redistributed by the water redistribution phenomenon, and to ensure safety against earth pressure and earthquakes. An anchor was attached to the ground and fixed in the soil on the back, creating a safe structure.

  Decide where to place the first-stage concrete block, excavate the earth and sand, roll well, add chestnut, and further roll. The planar shape of this block is a shape close to the T shape with a short flange on the one side of the H shape. FIG. 2 shows the drawing. Install a large number of first-stage concrete blocks. At this time, the long side of the flange is the front and the front is aligned. This is shown in FIG. Also, the thickness of the flange and web may be changed to be tapered.

  Next, planting soil S1 is thrown into the part surrounded by the flange and web of the two modified T-shaped blocks 1, and backside earth and sand G1 is thrown into the back of the modified T-shaped block 1. The thickness of the soil of S1 and G1 depends on the height of the block, but is about 10 cm when the block height is 25 cm, and 40 cm to 60 cm when the block height is 100 cm.

  Next, the front partition form 2 and the back partition form 3 are installed. This is shown in FIG. The earthquake-resistant connecting concrete 4 is placed to the upper end of the modified T-shaped block 1 in the space surrounded by the flanges and webs of the two partition molds and the modified T-shaped blocks 1 on both sides. The opening K is formed by placing the seismic joint concrete 4. This is shown as K in the CC cut view of FIG. The height of the concrete is about 15 when the height of the modified T-shaped block 1 is 25 cm, and is 60 cm to 40 cm when the height is 100 cm. Before placing this concrete, high-quality paper is laid on the bottom.

  Next, after the seismic joint concrete 4 is hardened, the front partition mold 2 and the back partition mold 3 are removed, and the backside earth and sand G2 is back-filled and rolled on the back of the modified T-shaped block 1 up to the upper end.

  Since the planting fence 5 is formed in the part surrounded by the front surface of the earthquake-resistant connecting concrete 4 and the flanges and webs of the two modified T-shaped blocks 1, the planting soil S <b> 2 is put in the planting fence 5 and the plant 6 is Plant. This is shown in FIG.

  Next, work on the second stage. On the modified T-shaped block 1, the second-shaped modified T-shaped block 1 is installed in a staircase pattern, shifted to the back side. This is shown in FIG. There are cases where a staggered pattern is used as shown in (a) of this plan view and webs are aligned as shown in (c). The front of the bottom surface of the second-stage modified T-shaped block 1 is placed on the rear end of the first-stage modified T-shaped block 1, and the latter is placed on the back-ground soil that has been compacted. The backside earth and sand should be of good quality and rolling should be done every 20-30cm. Next, as in the first stage, the planting soil S1 is introduced into the portion surrounded by the flange and web of the two modified T-shaped blocks 1, and the back soil G1 is introduced into the back of the modified T-shaped block 1. Subsequent operations are the same as in the first stage. The third and subsequent stages are the same as the second stage. Install the specified number of steps and finish the work.

  It is confirmed that water is supplied by the redistribution phenomenon of water in the soil described in the means for solving the problem and that it grows through the soil where the roots of the plants are connected. In FIG. 8, planting soil S <b> 2 in the planting basket 5 for growing the plant 6, planting soil S <b> 1 below this and the earthquake-resistant connecting concrete 4, backside earth and sand G <b> 1 and backside Four pieces of earth and sand G2 are integrally connected through the opening K on the back surface of the two modified T-shaped blocks 1. Rainwater U and spring water Y on the back penetrate into the backside soil G2 and backside soil G1, and are supplied to the planting soil S1 and the planting soil S2 by the redistribution phenomenon of the water in the soil. Grows for seeking.

  A case where the back soil on the back is a high embankment and the earth pressure is large is referred to as Example 2. After installing the back partition form 3 in the first line of the paragraph 11 of Example 1, before placing the earthquake-resistant connecting concrete 4, a hole is made in the back partition form 3, and a reinforcing bar or an anchor bolt with a hook and After inserting the anchor 7 made of a nut and attaching the nut, the seismic connection concrete 4 is placed. After the concrete is hardened, the front partition form 2 and the back partition form 3 are removed, and the back of the modified T-shaped block 1 Then, the backside earth and sand G2 is back-filled and rolled up to the upper end, and at this time, an anchor plate 8 and a nut are attached to the end on the back side of the anchor 7 and embedded and rolled and fixed in the backside earth and sand G2. This is shown in FIG. Others are the same as in the first embodiment. This is defined as claim 2.

  In some cases, the shorter flange of the deformed T-shaped block 1 may have only a portion where the earthquake-resistant connecting concrete 4 is provided and the other may not exist. This is shown in FIG. This applies to the first and second embodiments.

  In some cases, the odd-shaped T-shaped block 1 may have a T-shape without the shorter flange. In this case, the portion in contact with the earthquake-resistant connecting concrete 4 is chipped to improve the synthesis. The symbol for the chipping portion is T, and this is indicated by the hatched portion T in the side view of FIG. This applies to the first and second embodiments.

  FIG. 10 shows a box shape in which every two odd-shaped T-shaped blocks 1 are integrated. Since the opening K is manufactured at the factory, the number of the earthquake-resistant connecting concrete 4 to be cast in the field is halved, so that the work efficiency is improved. Correspondence to the curve is limited in a plane.
