Construction method for preventing slurry from overflowing in underground diaphragm wall pouring construction
A slurry overflow prevention construction method used in underground diaphragm wall pouring construction comprises the following steps that (1) before an underground diaphragm wall first-stage groove is excavated, the underground diaphragm wall first-stage groove and an adjacent non-excavated area are excavated to form a slurry buffer area; 2) laying a slurry discharge pipeline in the slurry buffer area, wherein the slurry discharge pipeline is connected to a slurry pump; (3) a first-stage groove of the diaphragm wall is excavated; (4) first sealing operation of a first-stage groove of the diaphragm wall is carried out; (4.1) a pouring frame is erected above the first-stage groove of the underground diaphragm wall, and concrete pouring is conducted; 4.2) continuously extracting the slurry overflowing into the slurry buffer area by a slurry pump; (5) after the first sealing operation is completed, concrete is continuously poured; by the adoption of the method, the problem that wall protecting slurry overflows and enters a guide wall in the underground diaphragm wall construction process is solved, the problems that site pollution is caused by the slurry and cost is increased due to the fact that the total using amount of the slurry is increased are solved, and the purposes of zero pollution and low cost of underground diaphragm wall construction are achieved.
一种用于地连墙浇筑施工中的泥浆防外溢施工方法，包括以下步骤：1）地连墙一期槽开挖前，对地连墙一期槽以及相邻未开挖区域开挖形成泥浆缓冲区；2）在泥浆缓冲区内铺设排浆管道，排浆管道连接至泥浆泵上；3）进行地连墙一期槽开挖；4）进行地连墙一期槽的首封作业；4.1）在地连墙一期槽上方搭设浇筑架，进行混凝土浇筑；4.2）泥浆泵持续对泥浆缓冲区内溢进泥浆进行抽取；5）完成首封作业后，继续浇筑混凝土；6）浇筑混凝土至冠梁设计底标高。本发明采用上述方法，在地连墙施工中解决了护壁泥浆溢出并进入导墙内的问题，避免了泥浆产生现场污染以及增加泥浆的总用量所导致的成本上升问题，实现地连墙施工的零污染、低成本目标。
