BLOCK OF BREAST WALL FOR ASSEMBLAGE AND BREAST WALL CONSTUCTING METHOD USING WHICH

摘要

A prefabricated retaining wall block is provided to construct a retaining wall quickly and strongly without restriction on a construction area, to shorten a period of construction by constructing a retaining wall using pre-manufactured retaining wall blocks and to couple with other blocks in the fitting type without using a separate binder. A prefabricated retaining wall block is formed by piling up support blocks(100) to engage crisscross, and connecting outer support blocks(100-1) forming the surface of a retaining wall with inner support blocks(100-2) abutting on the surface of a cutting area using binding blocks(200) to have a lattice structure inward, wherein the latticed inner part(S) formed by the binding blocks and the support blocks and the space between the inner support blocks and the surface of the cutting area are filled with filling materials. A construction method of a retaining wall using a prefabricated retaining wall block comprises the steps of: placing foundation concrete to be inclined downward toward the inside of a retaining wall to be installed; installing binding blocks on the foundation concrete; piling up support blocks and binding blocks repeatedly and filling up the inside and the outside with filling materials; and after piling up to the appointed height, finishing up the top of a retaining wall by placing crown concrete.
