PURPOSE:To simplify a foundation work and to shorten a term of works, by a method wherein one of the right and the left end surface of a block formed in a polygon in cross section having a horizontal bottom and a sloped upper surface is formed in a projection, and the other is formed in a recess being capable of engaging with the projection. CONSTITUTION:A block 1 for foundation concrete is formed in a shape in that the one corner part of a square column is notched obliquely, and has a horizontal bottom 2 and a slope upper surface 3. Meanwhile, a concave coupling part 4 is integrally formed in one end surface, and a convex coupling part 5, being capable of engaging with the concave part, is integrally formed in the other end surface. The adjoining surfaces of the plural concrete blocks 1 are filled with adhesive, and the adhesive is applied thereon. The concave coupling part 5 is engaged with the concave coupling part 4 for joint to form a foundation part. Slope reinforcing blocks are then piled up on the foundation concrete blocks 1. This eliminates forms in place, concreting, and curing, when a foundation part is formed, resulting in the possibility to immediately start a following work. |
