Abstract

PROBLEM TO BE SOLVED: To facilitate digging by digging the soil inside a cylindrical wall body which is installed on a surface of the ground, removing the soil, and applying its self-weight or load to sink it down to a predetermined depth so as to construct a basement in the wall body which is embedded. SOLUTION: A cylindrical wall body 1 is installed on a surface of the ground G, and the soil is digged by a digging blade 3 which rotates along an inner peripheral wall in a lower end part and is removed out of the wall body 1. The rotary shaft 31 of the digging blade 3 is rotated and driven by a motor. It is sunk due to self-weight of the wall body 1 and is embedded into the ground at a predetermined depth. It may be sunk by applying load. A basement is constructed in a space of the wall body 1. The wall body 1 is a cylindrical body made of reinforced concrete and is divided in the circumferential direction and in the direction of height for transportation. The wall body 1 is installed on an inner side of parallel foundations 2, 2 of a building, but a part thereof may be provided by sticking out to the outside. Consequently, the digging becomes easy, work man-hour can be reduced, and a wall thickness of the wall body 1 can be reduced to achieve the economical efficiency.
