迅速化する所期の目的を莞全に達成するものである。The prefabricated box-type retaining wall of the present invention having the structure and function described above has extremely few types of component parts for forming the component units, so it is possible to standardize the component parts and facilitate factory production. Assembly tools are also simplified, making prefabricated construction easier.
In addition, because the structure is designed to connect the structural units and assemble and form the outer shell, it is possible to lay the ground according to the ground and topographical conditions, and therefore to perform efficient land leveling work, which is different from the conventional method described at the beginning. The intended purpose is to simplify and speed up the assembly and installation work at the construction site by omitting the transportation of heavy equipment necessary for constructing a retaining wall to the construction site, as in the case of concrete retaining walls. It is to be fully achieved.
