CONSTITUTION: A plastic soil retaining plate comprises a soil retaining plate body(2) and a rotary coupler. The soil retaining plate is made of a plastic. The soil retaining plate body comprises a pair of panels(6) and ribs(8). The pair of panels are arranged at a predetermined interval to an even direction. The ribs are connected between the panels. The rotary coupler is formed in the soil retaining plate body and joined to the other soil retaining plate. The rotary coupler comprises a first assembly unit(4a) and second assembly unit(4b). The first assembly unit is formed in an end part of the soil retaining plate body. The second assembly unit is formed in the other end part and has a shape corresponding to the first assembly unit. |
