METHOD FOR CONTINUOUSLY CONSTRUCTING INDEPENDENT WATERTIGHT RETAINING WALLS BY IMPROVING THE GROUND FOR HEAVING AND BOILING AND A COMPOSITE WALL CONSTRUCTION METHOD OF A STRUCTURE

摘要

PURPOSE: A method for continuously constructing independent watertight retaining walls with the ground improvement and a composite wall construction method of a structure are provided to improve the structural stability by combining the composite wall with the outer wall of the structure and stabilizing the excavation bottom. CONSTITUTION: In a method for constructing an independent composite watertight retaining wall including watertight holes, H-piles and iron meshes(3), a composite retaining wall(1) is constructed, and the soft ground around the excavation ground is improved without excavation. The plain independent underground wall body is formed by continuously and forcibly stirring high strength cement and soil to an appointed depth. The continuous composite retaining wall is manufactured by inserting H-beams or steel reinforcement meshes at regular intervals(about 2.5 ¯ 3.5 m) according to the ground condition. The composite wall integrally formed with the retaining wall is constructed in a structure(2).
