Construction method of underground diaphragm wall below important pipeline
The invention discloses a construction method for an underground diaphragm wall below an important pipeline, and relates to the technical field of underground diaphragm wall construction. The construction method comprises the following construction steps that S1, the underground diaphragm wall is subjected to framing; s2, earthwork is manually excavated downwards at the important pipeline until the important pipeline is exposed, and an enclosure structure is constructed on the peripheral side of the important pipeline; s3, underground diaphragm wall earth excavation is conducted through a grooving machine, and a groove to be poured is formed; s4, a reinforcement cage is put into the pouring groove, the reinforcement cage of the second diaphragm wall or the reinforcement cage of the third diaphragm wall is put down, then the reinforcement cage of the first diaphragm wall is put down, the reinforcement cage of the first diaphragm wall is horizontally moved to the position below the important pipeline, and finally the remaining reinforcement cage is put down; and S5, concrete of the underground diaphragm wall is poured, and the underground diaphragm wall is formed. According to the method, the influence on important pipelines during underground diaphragm wall construction can be reduced.
本申请公开了一种重要管线下方地下连续墙施工方法，涉及地连墙施工的技术领域，包括以下施工步骤：S1、对地下连续墙进行分幅；S2、在重要管线处人工向下开挖土方，直至露出重要管线，在重要管线周侧施工围护结构；S3、利用成槽机械进行地下连续墙土方开挖，形成待浇筑槽；S4、向浇筑槽内下放钢筋笼，先进行第二幅地连墙或第三幅地连墙钢筋笼的下放，再进行第一幅地连墙钢筋笼的下放，并将第一幅地连墙钢筋笼平移至重要管线下方，最后进行剩余一幅钢筋笼的下放；S5、浇筑地下连续墙的混凝土，形成地下连续墙。本申请能够降低地下连续墙施工时对重要管线的影响。
