摘　　要：文章介绍了在超深强透水地层防渗墙墙段间采用平接法连接的关键施工技术,即防渗墙槽孔垂直度、接头处理、混凝土浇筑质量的有效控制措施。通过工程实践,证明了该技术在超深、强透水地层混凝土防渗墙施工中应用的可行性,防渗墙防渗效果满足设计要求,较其他连接方式有很大优势,可为其他类似工程提供借鉴。In this paper,we introduced the key construction techniques of using the flush connection method to connect the sections of the impermeable wall of ultra-deep and strong permeable stratum,that is,the effective control measures of the verticality of the slot holes of the impermeable wall,joint treatment and the quality of concrete pouring.Through engineering practice,it is proved that this technology is feasible in the construction of impervious wall of concrete in ultra-deep and highly permeable stratum.The anti-seepage effect of the impervious wall meets the design requirements and has great advantages over other connection methods,which can provide reference for other similar projects.
