PURPOSE:To shorten a term of works, by a method wherein foundation blocks are aligned at given intervals on a foundation bed, and after reinforcing bars as well as main reinforcing bars are arranged, concrete is placed on the arranged reinforcing bars. CONSTITUTION:After cobble-stones 3 are laid in a trench 2, L-shaped foundation blocks 4 made of precast concrete are arranged at given intervals on the cobble- stones 3. Lateral main reinforcing bars 6 are extended through holes 5 on the blocks 4 for arrangement, and auxiliary reinforcing bars 7 are arranged orthogonally to the lateral main reinforcing bars 6 to form a reinforcing bar lattice. After forms 8 and 8a and concrete blocks 10 and 11 are installed, concrete 9 is placed in a reinforcing bar arrangement surrounded with the blocks 4 and the forms 8 and 8a to form a surface in conformity with the blocks 4. |
