PROBLEM TO BE SOLVED: To provide a retaining wall which has a simple structure and can be increased in bulk. SOLUTION: A precast retaining wall 1 is disposed on a bank 5, and is composed of minimum component units of a foundation precast panel 9 and a retaining wall precast panel 11 connected to the upper surface of the foundation precast panel 9. The precast retaining wall 1 also includes a bracing block 13 that is disposed to connect the foundation precast panel 9 to the retaining wall precast panel 11. A slot 17 is formed on the upper surface of the body 15 of the foundation precast panel 9, and a projection 27 is formed on an end face of the body 25 of the retaining wall precast panel 11. The projection 27 corresponds in shape to the slot 17 of the foundation precast panel 9. Hence the projection 27 of the retaining wall precast panel 11 is engaged with the slot 17 to construct the precast retaining wall 1. COPYRIGHT: (C)2008,JPO&INPIT
