摘　　要：地下连续墙往往有着刚度大、抗渗透功能强,以及耐压持久等优点,广泛应用到我国水利工程建筑施工中,但是地连墙施工因为需要较大场地和空间也对施工环境提出了要求。为解决穿土坝地下连续墙施工中面临的交通中断、临近旧建筑物狭小施工空间、岩石地质硬、溶洞发育等问题,我公司创新提出了架设贝雷桥、导墙加固技术、潜孔钻岩层预破碎技术、贝雷桥整体吊装等综合技术,解决了复杂条件下地下连续墙施工困难的问题,可在类似工程施工中推广应用。The underground diaphragm wall often has the advantages of high rigidity,strong anti-penetration function,and durable pressure resistance,and is widely used in the construction of water conservancy projects in China.However,the construction of the underground diaphragm wall also proposes requirements for the construction environment because it requires a large site and space.In order to solve the problems of traffic interruption,narrow construction space adjacent to old buildings,hard rock geology,and development of karst caves in the construction of underground diaphragm walls of earth-piercing dams,our company innovatively proposes the comprehensive technologies such as the erection of Bailey bridges,the reinforcement of guide walls,down-the-hole drilling rock stratum pre-crushing technology,and Bailey bridge overall hoisting,which have solved the difficult construction problem of underground diaphragm wall under complex conditions,and can be popularized and applied in similar engineering construction.
