Zusammenfassung:	PURPOSE:To standardize assembling process of reinforcing bars and to reduce term of works to a great extent by installing a reinforcing bar basket assembled in advance to a space between an internal form made of segments and an external form made of precast boards, and by placing concrete to the space afterward. CONSTITUTION:A reinforcing bar basket 14 is made in advance by assembling internal reinforcements, external reinforcements, shear reinforcing bars and the like, which are all necessary for construction of a concrete side wall, into a basket shape. Then a hole in necessary size is dug to the ground and a bottom board 4 is formed in the bottom of the hole. To a place where the side wall is to be constructed, an internal form B made of segments 6 and 6 and an external form C made of precast boards 3 are installed, and concrete is cast after the reinforcing bar basket 14 is installed between both of the forms B and C.
