Diaphragm wall construction method for diaphragm wall penetrating through stratum
The invention discloses a diaphragm wall construction method for a diaphragm wall penetrating through a stratum. The diaphragm wall construction method comprises the following steps: S1, surveying andsetting out; S2, constructing a guide wall; S3, preparing slurry, specifically, preparing bentonite, a CMC tackifier, barite and water according to a preset proportion to form the slurry; S4, excavating a groove section; S5, cleaning the bottom and brushing the wall; S6, hoisting and placing a reinforcement cage; and S7, pouring a continuous wall with concrete. According to the diaphragm wall construction method, the slurry in the sediment at the bottom of a tank is recycled, meanwhile, new slurry is supplemented in time according to the machining process, so that the high-performance stability of the slurry in the tank is guaranteed, the tank wall is supported continuously for a long time, the collapse phenomenon of the tank wall is greatly reduced, recycling of the slurry is also realized, and therefore, the construction cost is reduced.
本发明公开了一种连续墙穿透地层的地连墙施工方法，包括步骤：S1，测量放线；S2，导墙施工；S3，泥浆配制：将膨润土、CMC增粘剂、重晶石以及水按预设比例配制以形成泥浆；S4，槽段开挖；S5，清底刷壁；S6，钢筋笼吊放；S7，连续墙砼浇筑。本发明通过对槽底沉渣中的浆液进行回收再利用，同时，根据加工进程及时补入新的泥浆，不仅保证了槽内泥浆的高性能的稳定性，从而使得槽壁得以持续长久的支撑而大大降低其出现坍塌现象，还实现了泥浆的回收再利用，从而降低了施工成本。
