Construction method of underground diaphragm wall in existing underground structure
The invention discloses a construction method of an underground diaphragm wall in an existing underground structure, and relates to the field of underground diaphragm walls, and the construction method comprises the following steps: S1, precipitation operation: reducing the underground water level of the peripheral side of an old underground structure below a bottom plate; s2, slope descending operation is conducted, specifically, a top plate of the old underground structure is dismantled, and a slope which is located from the terrace to a bottom plate and used for mechanical equipment to drive in is constructed; s3, grooving operation is conducted, specifically, according to the design position of the underground diaphragm wall, a local bottom plate is broken, and a continuous groove is dug; s4, a reinforcement cage is put down, and the reinforcement cage is put down into the continuous groove; and S5, pouring operation is conducted, concrete is poured into the continuous groove, and the underground continuous wall is formed after the concrete is solidified. The construction method has the effects that the situation that soil on the periphery of the enclosing wall collapses into a construction pit is reduced, and the safety of construction operation in the enclosing wall is improved.
本申请公开了一种既有地下结构内的地下连续墙施工方法，涉及地下连续墙的领域，其包括如下步骤，S1、降水作业，将老旧地下结构周侧地下水位降至底板以下；S2、降坡作业，拆除老旧地下结构的顶板，并施工自地坪下至底板且用于机械设备驶入的坡道；S3、成槽作业，根据地下连续墙设计位置，破除局部底板，并挖设连续槽；S4、下放钢筋笼，将钢筋笼下放至连续槽内；S5、浇筑作业，向连续槽内浇筑混凝土，混凝土凝固后即形成地下连续墙。本申请具有减少围墙周侧土壤向施工坑内塌陷的情况发生，并提升围墙内施工作业的安全性的效果。
