Can increase the strength.

On the other hand, blocks stacked in multiple stages to form the vertical wall is connected to or fixed to one end of the reinforcement on the back of the block using a separate connecting member such as a connecting pin or a ring, the earth and sand backfilled grid connected to the back of the block In addition, by laying together with the soil, the earth and sand of the block and the back were formed as an integral structure by the frictional force between the soil and soil so as to resist the soil pressure.

However, the process of constructing the reinforcement earth retaining wall with the conventional reinforcement involves the work of connecting the reinforcement to the back of the block at the construction site, so the work time is delayed during the connection process, and the soil is removed from the soil or the soil is removed. In case of dropping under pressure, not only the installation was difficult, but there was a problem in the structural stability of the retaining wall structure.
