CONSTRUCTION METHOD FOR CONTINUOUS UNDERGROUND WALL USING STEEL PIPE PILE

摘要

PURPOSE: To construct a continuous underground wall producing little residual soil, being economical and excellent in the water stop property. ;CONSTITUTION: Rotary intrusion steel pipe piles 1 each provided with a friction cutter 14 at the tip section and spiral ribs 12, 13 on the inner and outer faces at the tip portion are placed at an interval along the planned excavation line. Positions in contact with adjacent steel pipe piles 1, 1 on the non-excavation side of the steel pipe pile train are cylindrically excavated, and a hardener is injected to form soil cement pillars 2.;COPYRIGHT: (C)1994,JPO&Japio
