Title: Underground continuous wall construction method
Inventor: SAKAMOTO MASAHIRO
IPC: E02D5/20
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent a core member from moving and let it remain at a predetermined position even if concrete is placed after constructing the core member in a digged channel and prevent the occurrence of a clearance in mud soil mortar such as placed concrete. SOLUTION: The digged channel 1 is formed, a spacer 21 is attached to a bottom part of the core member 3 of H steel, and an interval between the core members is held to construct the core member in the digged channel. A pouring pipe 43 is arranged between the core members 3. Since mud soil mortar is injected from a channel bottom part and is filled while adjusting so that a face of the mud soil mortar rising so as to prevent eccentric pressure from acting on the core member 3 becomes constant, the core member 3 is constructed in a predetermined position with high precision. Moreover, since the mud soil mortar is filled after the core member 3 is constructed, it is unnecessary to add hardening delay agent to the mud soil mortar to obtain an underground continuous wall having high quality.
