Underground diaphragm wall grooving construction method
The invention relates to an underground diaphragm wall grooving construction method. The underground diaphragm wall grooving construction method comprises the following steps of surveying and setting out, guide wall construction, slurry preparation, groove excavation, bottom cleaning, reinforcement cage placement, underwater concrete pouring and wall toe grouting, wherein, the groove excavation is conducted, specifically, a double-wheel slot milling machine is adopted to complete unit groove sections through a jump hole excavation method; during the grooving, slurry is continuously injected into the groove, and the slurry surface is kept at a set height below the top surface of a guide wall and is higher than a set value of the underground water level; and meanwhile, a clay dispersing agent is added to the excavation face and a milling cutter.
本公开涉及一种地下连续墙成槽施工方法，包括测量放线、导墙施工、泥浆配置、沟槽开挖、清底、安放钢筋笼、灌注水下砼和墙趾注浆的步骤，其中沟槽开挖：采用双轮铣槽机以跳孔挖掘法完成单元槽段；挖槽时，不断向槽内注入泥浆，保持泥浆面在导墙顶面以下设定高度,且高出地下水位设定数值；同时，在开挖面和铣刀处加入黏土分散剂。
