According to the present invention, in a retaining wall constructed in a zigzag form in a number of lateral and longitudinal directions, a block using a reinforcing band which ensures fastening between blocks so that deformation does not occur in the retaining wall itself, and can withstand the load caused by the backfill material It is about a type of retaining wall.

In general, the retaining wall refers to a structure for preventing soil from falling down in response to earth pressure, and is defined as a wall that suppresses a material on one side of a wall to maintain an elevation difference. The surrounding slopes, roads, rail slopes, buildings, and stepped walls all represent potential loads on the retaining wall. Retaining walls are mainly divided into three types: gravity type, cantilever type and reinforced earth retaining wall. A "gravity retaining wall" is a form of retaining wall without reinforcement that withstands the load of soil confined by the weight of the blocks themselves. In the case of gravity retaining walls, each block is composed of concrete or stone blocks, which increases construction costs. Gravity retaining walls rely on the weight of the structure to withstand earth pressure.

Excavation of soil behind a retaining wall does not affect the structural strength of the retaining wall. Cantilevered retaining walls typically have a structure of slabs piled in the soil and derive their bearing capacity from the resistance to rotation of the slats under the supported soil. The cantilever retaining wall has a horizontal base section buried underneath the backfill, and the backfill soil has a stem section extending vertically and permanently connected to the base to form a wall. Cantilevered retaining walls rely on the weight of the backfill at the base to prevent the wall from tipping.
