The present invention relates to a front greening method of the reinforcement soil retaining wall and the construction method of the fill and cut section using artificial soil, and more specifically, using the soil arching effect of the soil filling backing soil And it is applied to the cut portion retaining wall relates to a method for ever-greening the retaining wall through environmentally friendly greening and its construction method.

In general, the front vegetation and greening method of reinforcement soil retaining wall is a potted vegetation method in which the retaining wall blocks are laminated with setback, and vegetation is carried out in the back biting space. Korea Utility Model Registration No. 0335073, Utility Model Registration No. 0297571 In addition, there is a Korean Utility Model Registration No. 0341395 and Utility Model Registration No. 0324831 as a method of planting by combining the potted form between the retaining wall block and the block. These two types of vegetation method can be planted somewhat in the waterside area where water is supplied throughout the year, but the block pot depth is shallow because the plant dries up due to the increase of the temperature of the block itself due to the sun's radiant heat and the roots fall sufficiently. There is a problem with being a permanent vegetation. In addition, as a vegetation method similar to this, there is a vegetation method in which plants are rooted in the space using a porous concrete block, and Korean Patent Registration No. 0322869, Patent Registration No. 0322868, Utility Model Registration No. 0304540, and the porous concrete ( Or blast furnace slag) blocks form blocks with porous granules, so that the compressive strength is lowered to 150 kg / cm 2 for 28 days, and it is difficult to build a retaining wall having a height of 2 m or more because a crack occurs in the block. In addition, since the roots of plants must pass through the porous grains, there are obstacles to vegetation, and a mixed material capable of neutralizing strong alkaline concrete (or blast furnace slag) should be added. On the other hand, since the vegetation method using the porous concrete block can be permanently vegetated only in the region where water is continuously supplied, there is a problem of vegetation that the plant dies in the region where the reinforcement soil retaining wall is generally applied except the lake. In addition, Korean Patent Registration No. 0408850, which allows vegetation through hollows of blocks, is similar to the method of letting the roots of plants fall between concrete grains, and is designed to continuously vegetate the soil on the back of the block. There is a problem that is not vegetation as it is. Similar to the above vegetation method, Korean Patent Registration No. 0377449, Patent Publication No. 1995-0011723 installs a mat (non-woven fabric) on the back of the wire mesh wall to record the front of the plant with soil suitable for plant growth. The mat (nonwoven) itself is a considerable obstacle because it is vegetated through the wire mesh, and it is difficult to actually vegetation, and due to the low stiffness of the wire mesh, the wire mesh is pushed toward the front of the retaining wall when the heavy equipment is compacted. In particular, it is difficult to align the retaining wall linearity due to the fact that there is a hungry phenomenon in the overlapped part of the top, bottom, left and right, so that it is difficult to construct the site by using the supporting equipment such as scaffold composed of steel pipe pipe. There is this. In addition, the Republic of Korea Patent Registration No. 0393515 is a technology designed to be a natural vegetation between the laminated spaces by stacking the concrete beams, this technology is actually difficult to supply moisture between the concrete beams due to the sloping slope of the concrete beams and slopes and concrete Since the backfill soil width between the beams is not deep, vegetation is difficult.

Regarding the application of cut retaining wall, Korean Patent Registration No. 0372821 and Patent Registration No. 062689 are designed to apply blocks and concrete panels to slopes, respectively. In addition to visual stability, it is not environmentally friendly.

An object of the present invention to provide a method and a construction method for recording the front surface of the reinforced soil retaining wall using the artificial soil in order to solve the problems of the reinforcement soil retaining wall front wall vegetation method as described above. will be.

The present invention for achieving the above object is to prevent the plant from dying due to the rise of the temperature of the block itself due to the sunlight in the air, and to remove the obstacles so that the plant can take root well, the greening to the front of the wall It is possible to provide a vegetation retaining wall front vegetation method and a method of constructing the reinforced soil retaining wall so that nutrients and moisture are sufficiently supplied so that the retaining wall is always greened.
