Hereinafter, with reference to the accompanying drawings, preferred embodiments that do not limit the present invention will be described in detail.

1 is a perspective view showing the front member of the prefabricated retaining soil retaining wall for greening according to the present invention, Figure 2 is a side view of the front member shown in Figure 1, Figures 3 and 4 of the prefabricated retaining soil retaining wall according to the present invention, respectively 5 and 5 are cross-sectional views showing the construction state of the prefabricated soil retaining wall according to the present invention.

As shown in FIG. 1 to FIG. 5B, the present invention is connected to the steel lattice frame 10 and the lattice frame 10 forming the front surface of the retaining wall and embedded in the fill body 30 by frictional resistance and passive resistance. In constructing a retaining wall capable of greening using a reinforcement 20 to support the grid 10 and the fill body 30, the steel grid 10 is a plurality of vertical members 12 connected up and down The horizontal flat steel 14 is installed in a lattice shape, but the horizontal flat steel 14 is assembled to be inclined upward toward the front of the vertical member 12 so that the soil of the fill part 30 is lattice frame ( 10) is not to be lost to the outside through the upper and lower ends of the vertical member 12 as a long hole for fixing to the base (D) and the coupling with the lower end of the vertical member of another grid frame connected thereon The upper and lower coupling portions 13 and 13 'are formed, and the left and right sides of the horizontal flat steel 14 The two sides, there are formed a number of flat steel (14) upon engagement of the lattice framework of a number of flat steel material is to fulfill a straight line bent in the upper and lower short sides form a coupling portion (15,15 ') adjacent each.

The upper and lower coupling parts 13 and 13 'are assembled by conventional bolts and nuts, and can be fixed by adjusting the horizontality of the lattice frame, and fastening the knots and nuts to allow the lattice to slide in the vertical direction. do.

In the present invention, since the side coupling portions 15 and 15 'are each formed to be bent up and down to form a step, the construction of a straight retaining wall as shown in FIGS. 1 to 5B as well as a curved shape as shown in FIG. Even when a retaining wall is to be constructed, the side joints 15 and 15 'are bent without a certain degree of interference between horizontal flat steels 14 between adjacent lattice frames 10 by a step difference. Since it is possible to assemble a furnace, it is possible to form a natural curved retaining wall surface suitable for the site state, and as shown in FIG. 7, side coupling portions 15 and 15 'between the lattice frames are vertically raised during uneven settlement of soil and ground. Since it is spaced apart in the stepped state and is coupled with a bolt and a nut, even if one side of the grid is settled, the other side grid is absorbed by the up and down sliding action of the side coupling portions 15 and 15 '.Do not and can prevent the deformation such as warpage or teuleojim of the retaining wall.

In the vertical member 12 forming the grid 10, a reinforcing member connecting hole 16 is drilled up and down long by a predetermined section, and a pair of the reinforcing member connecting hole 16 is shown in left and right as shown in FIG. The end of the connector 17 is fixed with a bolt and the connecting pin 18 is fitted to the rear end of the connector 17 to fix the end of the strip-shaped synthetic fiber reinforcement (20).

In addition, in the case of using the galvanized steel reinforcement, the connector 17 'as shown in FIG. 8 may be used, and the reinforcement used for the construction of the retaining wall for greening according to the present invention is the above-described galvanized steel reinforcement, band-shaped composite. Fiber reinforcements, geogrids, chains, and the like can be used in the construction of prefabricated reinforcement retaining wall, such as a variety of reinforcement can be used, in this case, it is possible to manufacture and use a connector for connecting the front end of each reinforcement to the grid.

On the other hand, since the reinforcement connecting hole 16 formed in the vertical member 12 has a long hole shape in the vertical direction, even if the reinforcing material 20 is lowered together with the reinforcement soil and ground subsidence, the connector 17, 17 'is also reinforcement material. As it descends along the connection hole 16, deformation of the grid frame does not occur even when the reinforcement soil is displaced and the ground subsides.

Grid frame 10 of the present invention is usually made of flat steel, it is preferable to extend the life by forming a galvanized or synthetic resin coating on the surface to prevent corrosion after construction.

Hang the reinforcement 20 by using the connector 17 in the reinforcement connecting hole 16 is located, pulled to a predetermined tensile force, and the earth is put on it again.

In this way, after the lower grid is erected, the basic grid is lifted between the lower grids and assembled with the lower B grid, which is built up first. If you set it up so that it does not fall down, and then repeat the installation work of reinforcement and compaction of soil, as in the lattice frame at the bottom, you can build the retaining wall to the designed height, and use the B type grid again at the upper part of the retaining wall. Thus, the retaining wall can be formed such that adjacent grids have the same height.
