FIG. 13 is a cross-sectional view illustrating a structure of mounting and restraining members of a prefabricated retaining wall according to a tenth embodiment of the present invention.

Referring to FIG. 13, the prefabricated retaining wall according to the present invention is formed of a hexahedron such that a plurality of uniform dogs are stacked, and a vegetation hole 912 penetrating from an upper surface to a lower surface of the hexahedron, a coupling protrusion 914 formed on the upper surface of the hexahedron, Between the block 910 and the block 910 provided with a coupling hole portion 916 penetrating from the top surface of the cube to the bottom, the coupling protrusion 914 is inserted, and the installation groove 918 formed on the upper surface of the cube. A reinforcing member 950 interposed therebetween to prevent the block 910 from collapsing due to the earth pressure of the rearing soil 920, and a catching member 970 wrapped by the reinforcing member 950 and seated in the installation groove 918. And the installation groove 918 includes a front inclined surface 918a that is inclined toward the front side of the block 910, and an inclined angle that is inclined toward the rear side of the block 910, compared to the front inclined surface 918a. Includes a rear inclined surface 918b formed small.

In this embodiment, the front inclined surface 918a and the rear inclined surface 918b of the installation groove 918 are formed in an asymmetrical shape, and the rear inclined surface 918b is formed to have a gentler slope.

Therefore, when the locking member 970 is interposed between the rear slope surface 918b and the bottom surface of the block 910, the locking member 970 is pressed by the bottom surface and the rear slope surface 918b of the block 910, so that no additional restraining member is provided. The reinforcement 950 can be prevented from being separated from the locking member 970.

In addition, the locking member 970 of the present embodiment may include a circular bar or a corner bar, and when the corner bar is used as the locking member, the corner part protrudes in a wedge shape, and is formed between the rear slope surface 918b and the bottom of the block 910. It can be installed to be in close contact with both sides.

As a result, since the restraining member that restrains the reinforcing material is inserted into the installation groove of the block, it is possible to provide a prefabricated retaining wall that prevents the reinforcing material from being separated from the block.
