Novel joint structure of large-diameter shield station foundation pit diaphragm wall and construction method
The invention relates to a novel joint structure of a large-diameter shield station foundation pit diaphragm wall and a construction method, the novel joint structure comprises a subway station diaphragm wall, a guide wall and a grouting structure, the guide wall surrounds the subway station diaphragm wall, the guide wall is formed by sequentially connecting a plurality of sections of standard knot guide walls, and female joints and male joints between the standard knot guide walls are in meshed connection; the underground diaphragm wall of the subway station comprises a plurality of sections of standard knot underground diaphragm walls, the two ends of each section of standard knot underground diaphragm wall are provided with an inner convex connector and an outer convex connector respectively, and the inner convex connectors and the outer convex connectors between the standard knots of the underground diaphragm wall are connected in an engaged mode. Comprising the steps of inner and outer guide wall construction, underground diaphragm wall grooving construction, underground diaphragm wall construction and joint treatment. The method has the beneficial effects that the leakage phenomenon at the joints of the underground diaphragm wall can be effectively relieved, the water leakage condition at the joints can be monitored, the quality and the construction efficiency of the underground diaphragm wall can be improved when a subway station foundation pit is subjected to enclosure, and the time cost is reduced.
本发明涉及一种大直径盾构车站基坑地连墙新型接缝结构及施工方法，包括：地铁车站地连墙、导墙和注浆结构，导墙围绕地铁车站地连墙，导墙由数段标准节导墙依次连接形成，标准节导墙之间的阴式接头和阳式接头相互咬合连接；地铁车站地连墙包括数段标准节地连墙，每段标准节地连墙两端分别设有内凸接头和外凸接头，地连墙标准节之间的内凸接头和外凸接头相互咬合连接；包括步骤：内外导墙施工、地连墙成槽施工、地连墙施工、接缝处理。本发明的有益效果是：具有能够有效减轻地下连续墙接缝处出现渗漏现象的效果，实现对接缝处渗漏水情况的监测，且能提高地铁车站基坑进行围护时地连墙的质量及施工效率，减少时间成本。
