PRE-FABRICATED EARTH RETAINING WALL STRUCTURE CONSTRUCTING METHOD USING PRESTRESSED TENDON

摘要

PURPOSE: A method for constructing prefabricated temporary retaining wall with tendons is provided to penetrate a fixing wedge pile in the lowest part of an H-beam pile, thereby preventing the sliding deformation of the lowest part of the H-beam pile in an excavation area side caused by soil pressure. CONSTITUTION: A method for constructing prefabricated temporary retaining wall with tendons is as follows. A prefabricated temporary retaining wall is installed in a trench excavation area. The prefabricated temporary retaining wall is penetrated into one-step excavation surface and a retaining panel(180a) is inserted in between H-beam piles(110a) and fixed. A fixing wedge pile(160a) is penetrated into and excavation bottom surface. Steel bars(150a) are tensed and mounted along a longitudinal direction of the H-beam pile. A bottom temporary strut(120b) being arranged in the excavation bottom surface is disassembled. An establishment is installed and constructed in the excavation bottom surface.
