Construction method capable of reducing filling coefficient of continuous wall concrete pouring
The invention relates to the technical field of underground continuous wall construction, in particular to a construction method capable of reducing the filling coefficient of continuous wall concrete pouring, which comprises the following steps that guide walls are built on the two sides of the axis of a continuous wall to be poured, and the distance between the guide walls is matched with the width of the continuous wall; a groove section between the guide walls is excavated, specifically, in the excavation process, slurry with the specific gravity being 1.15-1.25 g/cm < 2 > is injected into a groove, and the slurry is used for preventing the continuous wall from collapsing; groove sections are cleaned and accepted; hoisting the groove section reinforcement cage into the groove section; and concrete is poured into the groove sections, and construction of the continuous wall is completed. By injecting the slurry with the specific gravity of 1.15-1.25 g/cm < 2 > when the corresponding groove section is excavated, the wall protection effect of the groove section is good, the groove section is not easy to collapse, the possibility of subsequent pouring of the wall protection is reduced as much as possible, the filling coefficient is reduced, and the existing problems that the filling coefficient of the continuous wall often exceeds standard data in the construction process, and the construction efficiency is low are solved. And the quality of the whole project is influenced.
本发明涉及地下连续墙施工的技术领域，特别涉及一种能够降低连续墙混凝土灌注的充盈系数的施工方法，包括如下步骤：在待浇筑的连续墙的轴线的两侧修筑导墙，导墙的间距适配于连续墙的宽度；开挖导墙之间的槽段：开挖的过程中向槽内注入比重为1.15～1.25g/cm2的泥浆，泥浆用于防止连续墙塌陷；清理并验收槽段；吊装槽段钢筋笼至槽段内部；灌注混凝土于槽段内部，完成连续墙的施工。通过在开挖对应槽段的时候注入比重为1.15～1.25g/cm2的泥浆，使得槽段的护壁效果良好，槽段不易垮塌，尽可能减少了后续再次浇筑护壁可能性，减少了充盈系数，解决了现有问题存在的在施工过程中经常会出现连续墙的充盈系数超过规范数据，影响了整个工程的质量的问题。
