GROUND CONSTRUCTION METHOD USING DISPLACEMENT-CONTROL PILE

PURPOSE: A construction method of an underground wall using a displacement control pile is provided to efficiently drain water on the rear surface of an underground wall and to control construction errors. CONSTITUTION: A construction method of an underground wall using a displacement control pile is as follows. Displacement control piles(100), in which displacement control tendons(110) are previously set on the rear surfaces, are manufactured. An underground wall is formed by consecutively installing the displacement control piles in the ground. Pre-stress is applied to the underground wall in an opposite direction of displacement by tensing and anchoring the displacement control tendons. The ground of the front part of the underground wall is excavated.
