摘　　要：为了解决一般地连墙施工方案不能满足深层地连墙开挖要求以及使用大型机械带来的不必要的浪费和新旧泥浆置换及清孔不彻底等问题,结合天津金钟河地铁站地下连续墙施工的项目提出了气举反循环地连墙施工工艺,详细阐述了其施工方法、原理和优点,为实际工程提供实践经验。In order to solve the problems that the general wall-connected construction scheme cannot meet the requirements of excavation of deep ground wall,the unnecessary waste caused by the use of large-scale machinery,and the replacement of old and new mud and incomplete cleaning,combined with the construction of diaphragm wall in Tianjin Jinzhonghe subway station,this paper proposes the construction technology of air-lift reverse circulation of diaphragm wall,elaborates its construction methods,principles and advantages,and provides practical experience for practical projects.
