The present invention relates to a prefabricated reinforcement retaining wall for the greening using a metal front plate and a construction method of the retaining wall, and in detail, to produce a member of the front wall of the retaining wall with a metal front plate to allow vegetation, a separate inside the front plate It is possible to effectively prevent the outflow of earth and sand without installing mesh, non-woven fabric or vegetation mat, and it can be constructed as a straight or any type of curved vertical retaining wall according to the terrain of the retaining wall construction site. The present invention relates to a prefabricated reinforcement earth retaining wall for a greening using a metal front plate which is economical and has excellent workability and safety compared to the reinforced earth retaining wall.

In general, the prefabricated reinforced soil retaining wall has been developed and used, including a concrete panel method, a block building method, a method for building a metal front plate horizontally or vertically, a steel frame vegetation reinforced soil retaining wall method using a wire mesh. In the case of building retaining walls using existing concrete panels or blocks, each panel or block is interlocked and connected to each other in structural aspect, so that the whole retaining wall forms a rigid body. In case of local concentration, each panel or block is opened and soil is leaked out or cracks are generated. In extreme cases, the retaining wall is collapsed, and there is a problem of weathering according to the change of season and period after construction. There was a problem that the structural strength is lowered, there was a disadvantage that the concrete surface of the panel or block does not harmonize with the surrounding environment and gives a very visually depressed feeling.

In addition, when reinforcing earth retaining wall is made of concrete panels or blocks, the weight of the material is heavy, which required many people and equipment to be mobilized during the manufacture, transportation, and construction of retaining wall, which entails an increase in logistics costs, an increase in construction costs, and various difficulties in construction. It became.

On the other hand, in the steel frame vegetation reinforcement earth retaining wall method using the wire mesh or the method of building the metal front plate horizontally or vertically, the material is much lighter than the existing concrete panels or blocks, which improves the construction cost and improves the construction cost. Since the shape was simply arcuate, and the thickness of the metal plate had to be secured enough for the maintenance and corrosion of the form, the loss of material was heavy and heavy, and the vegetation was impossible because the entire surface was simply formed in the arcuate shape. There was a fatal disadvantage that it is not eco-friendly because it gives a dreary feeling that does not match the surrounding environment.

In addition, the steel wall vegetation reinforcement earth retaining wall method using the wire mesh allows the vegetation on the front of the retaining wall, but the front wall is constructed so that the soil, which is the foundation of the plant, is laid at an angle toward the rear to promote the rooting of the plant and the sticking of the stem Since the use of the site is less efficient, there is a problem of insufficient compaction on the front wall and earth and sand flowing down. This was heavy and had the disadvantage of additionally installing a separate mesh or nonwoven fabric or vegetation mat having a structure more dense than the front wall in order to prevent the outflow and displacement of the soil after the filling process and after filling.

When planting vertically, the roots of the plant can extend vertically toward the soil, so it grows smoothly. It has a larger vegetation area and absorbs a lot of light than the existing vegetation retaining wall, and the thermal conductivity of the front plate is low. In addition to minimizing the evaporation of moisture from the soil, which is the basis of plant growth, the plant itself It can be prevented from being dried and killed by it, and it can be constructed as a curved vertical retaining wall freely suited to the topography of the construction site, and it can be constructed in various local conditions such as roads, shifts (bridges), railways, urban centers, rivers, coasts It can be applied to retaining walls such as mountain retaining walls, and the vegetation area and surface area of the front wall are large, so that it can reduce environmental pollution including various noises generated around the front wall, and to install protection or soundproof walls on the retaining wall of the front wall. In this case, it is possible to construct a protective or soundproof wall continuously on top of the retaining wall without using any additional material and to use the same material as the retaining wall construction. It has a certain degree of elasticity in the direction to prevent lateral displacement and to prevent displacement from floating settlement. The face plate and reinforcing material are settled together to prevent displacement of the front wall, and even in the case of partial renovation and reconstruction, it is possible to replace the new front plate easily without digging any reinforcement soils. To provide a prefabricated reinforced retaining wall for the greening using the plate and the construction method of the retaining wall.

In order to achieve the above object, the present invention is to construct a retaining wall using a front plate which forms the front of the retaining wall and a reinforcing material connected to the front plate and embedded in the fill body to support the front plate by frictional resistance and supporting resistance.
