北京某论坛工程地下连续墙施工方法及应用研究

地下连续墙是一种具有截水、防渗、承重、挡水作用的地下连续钢筋混凝土墙体结构。该文结合具体工程案例进行支护方式的比选,针对优选的地下连续墙支护形式,相较传统的地下连续墙施工方法,提出地下连续墙的锁扣管连接方法及多种优化施工方法,同时对地下连续墙连接和管段的成槽进行质量监控,并就其在实际工程中所存在的问题进行详细剖析,提出相应的对策。针对地下连续墙支护体系施工对周边地铁的扰动进行影响分析,为工程的风险控制和安全保障提供切实可行的施工建议。

The underground diaphragm wall is a kind of underground continuous reinforced concrete wall structure with the functions of water interception,anti-seepage,load-bearing and water retaining.Based on the comparison and selection of support methods with specific engineering cases,this paper puts forward the locking pipe connection method of underground diaphragm wall and a variety of optimized construction methods according to the optimized support form of ground diaphragm wall and compared with the traditional construction method of ground diaphragm wall.At the same time,the quality of the connection of the diaphragm wall and the slotting of the pipe section is monitored,and the problems existing in the actual working process are analyzed in detail,and the corresponding countermeasures are put forward.This paper analyzes the influence of the construction of the ground diaphragm wall support system on the disturbance of the surrounding subway,and provides feasible construction suggestions for the risk control and safety guarantee of the project.
