PROBLEM TO BE SOLVED: To prevent a bottom base concrete from being moved by a lift pressure acting on the bottom base concrete caused by an underground water to prevent the underground water leakage from a boundary surface between the bottom base concrete and underground continuous wall. ;SOLUTION: Continuous walls 10 of an underground structure and a bottom base concrete 20 supporting the continuous walls 10 are constructed. When the continuous walls 10 are constructed, a recessed part is formed on a continuous wall 10 side of the boundary surface between the continuous walls 10 and the bottom base concrete 20 and, when the bottom base concrete 20 is constructed, the bottom base concrete 20 is deposited in the recessed part provided in the continuous walls 10.;COPYRIGHT: (C)2000,JPO
