As shown, the rear unit block 1200 has a front face 1210 and a rear face 1220, a left face 1230, and a right face 1240 facing the left face 1230. The rear unit block 1200 forms a compartment 1270 of an interior space defined by a front face 1210, a rear face 1220, a left face 1230, and a right face 1240, where the compartment 1270 is drained and downwards. In order to prevent the flow of the unit block 1200 has a through structure in which the top and bottom open to fill with crushed stone and / or soil.

In the present invention, the front surface 1210 of the rear unit block 1200 has semi-cylindrical front projections 1213 and 1214 extending lengthwise in both ends thereof. The front face 1210 of the rear unit block 1200 has one or more drain holes 1211 in its interior area, which drain water 1211 into the compartment 1270 in front of the lower row as shown in FIG. It serves to discharge to the front compartment 1170 of the front unit block 1100 disposed.

In construction, the semi-cylindrical front projection 1213 is inserted into the semi-cylindrical recess 1141, while the semi-cylindrical front projection 1214 is inserted into the semi-cylindrical recess 1113.

In addition, the rear surface 1220 has a coupling hole 1225 for fastening the vertical bar (1520) provided at one end of the coupler (1500). The coupling hole 1225 is formed in a shape corresponding to the cross-sectional shape of the vertical bar 1520, to facilitate the rotation of the vertical bar (1520) accommodated in the coupling hole 1225.

In addition, the front surface 1210 of the rear unit block 1200 should be formed to have a width and a length corresponding to the spaced space between adjacent front unit blocks 1100. The rear unit block 1200 supporting the front unit block 1100 is formed at the same height as the front unit block 1100.

In the retaining wall block assembly according to the first embodiment of the present invention, a process of assembling the front unit block 1100 and the rear unit block 1200 along the transverse direction and the longitudinal direction of the retaining wall will be described with reference to FIG. 5.

In the transverse assembly, the rear unit block 1200 is disposed in front of the fill body E (shown in FIG. 1), and each front unit block 1100 is disposed on both sides of the rear unit block 1200. The rear unit block 1200 inserts the coupler 1500 into the coupling hole 1225 so as not to be displaced from the front surface of the fill body. As shown in FIG. 1, the present invention may couple between the rear unit block 1200 and the fill body E by means of a coupler 1500.

The coupler 1500 is bent downward at the other end of the thin horizontal bar 1510, a vertical bar 1520 extending in a direction orthogonal to one end of the horizontal bar 1510, and the horizontal bar 1510. Consisting of the bent portion (1530).

The vertical bar 1520 is fitted into the coupling hole 1225 of the rear unit block 1200 and penetrates through the mesh-type geogrid as necessary to help position the coupler 1500 in the rear unit block 1200. For reference, the vertical bar 1520 is inserted between the coupling holes 1225 of the rear unit blocks 1200 stacked adjacent in the vertical direction as shown in order to fix the position between the rear unit blocks 1200 arranged vertically. Help. The horizontal bar 1510 extends longitudinally toward the fill body and the geograd orthogonally at the vertical bar 1520. The bent portion 1530 is bent downward as shown, it can be embedded in the interior of the body to prevent the displacement of the rear unit block 1200 from the body beforehand while maintaining the development of the geogradation.

The semi-cylindrical front projection 1213 of the rear unit block 1200 is disposed in the semi-cylindrical recess 1141 of the front unit block 1100, while the semi-cylindrical front projection 1214 is correspondingly the front unit. It arrange | positions to the semi-cylindrical recessed part 1131 of the block 1100. As a result, the adjacent unit blocks 1100 may be spaced apart from each other at predetermined intervals. In particular, the semi-cylindrical front projections 1213 and 1214 of the rear unit block 1200 are formed at both ends of the front surface, and these front projections 1213 and 1214 are formed on the side surfaces 1140 and 1130 of the front unit block 1100. The front unit block 1100 is inserted into the recesses 1141 and 1131 formed in the front portion, and protrudes to the front side than the rear unit block 1200.
