摘要
地下连续墙作为软土地区的一种深基坑围护结构,因其具有刚度大、整体性强、耐久性和防渗性好等优点,被广泛应用于深基坑中。为解决软土地区深基坑地下连续墙施工中容易造成的槽壁坍塌等工程事故,文中结合上海某工程在复杂地段地下连续墙施工,总结出深基坑地下连续墙在复杂地段关键施工技术,结果表明该工程地下连续墙施工的墙体垂直度、槽段接缝、槽壁稳定性和止水效果均符合设计要求,为今后类似地下连续墙的施工技术提供经验与借鉴。
As a kind of deep foundation pit retaining structure in soft soil area,diaphragm wall is widely used in deep foundation pit because for its strong rigidity,integrity,durability and impermeability.In order to solve the engineering accidents such as groove wall collapse in the construction of diaphragm wall of deep foundation pit in soft soil area,this paper summarizes the key construction technology of diaphragm wall of deep foundation pit in complex section based on the construction project of diaphragm wall of a certain project in Shanghai.The results show that the wall verticality,groove joint,groove wall stability and water stopping effectiveness in the construction of diaphragm wall of deep foundation pit.The results meet the design requirements,and provide experience and reference for similar underground diaphragm wall construction technology in the future.
