地下连续墙施工工艺

Construction Technology of Diaphragm Wall

地下连续墙的施工工艺较复杂,稍有不当会造成地下连续墙渗水、周围地表沉降等严重问题,造成严重的工程事故和财产损失,因此有必要对地下连续墙的施工工艺进行研究。通过工程经验和理论分析,建立了地下连续墙施工工艺体系,确定了地下连续墙相关技术参数,对地下连续墙施工工艺进行了研究,确定了其可行性;通过文献分析和现场实际情况,建殳了地下连续墙施工工艺体系,包括导墙施工工艺、地下管线及浅部障碍物处理、泥浆制配技术、成槽工艺、刷壁、清槽、吊装接头管技术、钢筋笼加工与吊放、混凝土浇筑、提升接头管;基于工程实际,总结了地下连续墙质量控制的要点,保证了工程顺利进行。

The construction technology of diaphragm wall is complex.If it is improper,it will cause serious problems such as water seepage and surface settlement around the diaphragm wall,which will cause serious engineering accidents and property losses.Therefore,it is necessary to study the construction technology of diaphragm wall.Through engineering experience and theoretical analysis,the paper establishes the construction technology system of diaphragm wall,and determines the relevant technical parameters of diaphragm wall,the construction technology of diaphragm wall is studied and its feasibility is determined;the construction technology system of diaphragm wall is established through literature analysis and field practice.The construction technology of diaphragm wall includes guide wall construction technology,underground pipeline and shallow obstacle treatment,slurry preparation technology,trenching technology,wall brushing,groove cleaning,joint pipe hoisting technology;based on the engineering practice,the key points of quality control of diaphragm wall are summarized,which ensure the smooth progress of the project.
