Recoverable semi-rigid connection underground diaphragm wall construction method
The invention discloses a recoverable semi-rigid connection underground diaphragm wall construction method, which adopts a semi-rigid joint form formed by combining a fore shaft pipe and reinforcing profile steel, not only increases the contact area of the connecting part of an underground diaphragm wall unit, but also improves the wall body strength and the waterproof and anti-seepage effects under the action of the reinforcing profile steel, and in addition, improves the construction efficiency of the underground diaphragm wall. And after the underground main body structure is constructed, the reinforcing profile steel is removed, and high-strength concrete is adopted for pouring to form a concrete consolidation body so as to form the underground diaphragm wall structure which is stable in structure, waterproof and seepage-proof. The problems that the joint of the underground diaphragm wall is insufficient in rigidity and prone to water seepage during construction of an existing underground diaphragm wall are solved.
本发明公开了一种可回收式半刚性连接的地下连续墙施工方法，采用锁口管与加固型钢的组合形成半刚性接头形式，既增加了地连墙单元的连接处的接触面积，又在加固型钢的作用下增加了墙体强度和防水防渗功效，此外，在地下主体结构施工后，拆除加固型钢并采用高强混凝土浇筑形成混凝土固结体以形成结构稳固、防水、防渗的地连墙结构。本发明解决了现有的地连墙施工时，地下连续墙的接头处刚度不足且易渗水的问题。
