Construction method based on shield launching underground diaphragm wall and supporting system
The invention discloses a construction method of an underground diaphragm wall and a support system based on shield launching. The construction method comprises the following steps: leveling a site to carry out guide wall construction and underground diaphragm wall construction, constructing a top beam and a concrete retaining wall after completion, erecting a first concrete support, and sequentially carrying out earth excavation and concrete support construction to a bottom plate position after completion; according to the ground sleeve valve pipe grouting method, on the premise that underground diaphragm wall reinforcing steel bars guarantee stress of an enclosure structure, grinding cutting and crushing of a cutter head of a shield tunneling machine are met, follow-up tunneling construction of the shield tunneling machine is facilitated, the working procedures such as tunnel portal chiseling are avoided, construction safety is guaranteed, the use requirement for underground diaphragm wall shield initial supporting and launching is met, and the construction cost is reduced. In the construction process, the reinforcement cage is machined, hoisted and pre-embedded parts are reserved according to related requirements, the requirement for shield initial supporting and launching is met, the construction period is shortened, unnecessary waste of building materials is avoided, high environmental protection and economic value is achieved, and popularization applicability is achieved.
本发明公开了一种基于盾构始发地下连续墙及支护体系施工方法，平整场地进行导墙施工、地下连续墙施工，完成后施工冠梁及混凝土挡墙、架设第一道混凝土支撑，完成后依次进行土方开挖及混凝土支撑施工至底板位置；通过地面袖阀管注浆法解决了地下连续墙钢筋在保证围护结构受力的前提下，满足盾构机刀盘的磨切和破碎，方便盾构机的后续掘进施工，避免了洞门凿除等工序，确保了施工安全，满足了地下连续墙盾构初支始发的使用要求，在施工过程中，结合相关要求对钢筋笼加工、吊装、预留预埋件设置，实现了盾构初支始发的要求，减少了施工工期，避免了不必要的建筑材料浪费，有较高的环保及经济价值，具有推广的适用性。
