摘　　要：为提高软土、中风化泥质粉砂岩和高地下水位地层的水工筒井式超深地下连续墙施工技术水平,通过对超深地下连续墙的重点如成槽、钢筋笼吊放及对接、混凝土绕流等3个关键环节进行技术把控,找到各环节的技术难点,根据施工中遇到的实际问题,分析原因并提出对应防控改进措施。通过实践证明这些措施操作简便、行之有效,可为类似超深地下连续墙项目提供指导和借鉴。In order to improve the technical level of hydraulic tube well type ultra-deep underground diaphragm wall construction in soft soil,medium weathered argillaceous siltstone and high groundwater level strata,three key technical links including groove formation,steel cage hoisting and docking,and concrete circulation in the construction of ultra-deep underground diaphragm wall are studied,and the technical difficulties of each link and the actual problems encountered in construction process are found.The reasons of these difficulties and problems are analyzed and the corresponding prevention and control improvement measures are proposed.The practice proves that these measures are simple and effective,which can provide guidance and references for similar ultra-deep underground diaphragm wall projects.
