PURPOSE: To improve constructing properties by a method wherein wall reinforcing bars are arranged in a landslide protection wall, PC poles are built in at appropriate intervals on this side of the wall reinforcing bars and fixed by building in PC wall boards between them and a beam type frame is assembled between the head parts of the poles. CONSTITUTION: Wall reinforcing bars 13 are arranged by building in mesh bar units along a landslide protection wall 12 and PC poles of which tape bars fastening main bars tightly are made to project from one side are built in at appropriate intervals. Between the poles 1, subsequently, a PC wall board 10 equipped with a reinforcing iron frame 17 in the direction of the length of one side is built in and fixed thereto and concrete is placed up to the top part of the wall board 10. Then, another wall board 10 fitted with the iron frame 17 in the same way as the above is hung up and built on the lower wall board 10, the upper wall board 10 is fixed to the poles l and the lower wall board 10, a beam type frame is assembled on the upper wall board 10 and concrete is placed. By forming an inner formwork by the poles l, the wall boards 10 and the beam type frame, an assembling process of the inner formwork is reduced sharply and thereby constructing properties can be improved.
