摘　　要：在基坑施工过程中,由于受到地下水的压力影响,常常会出现衬墙渗漏的问题。衬墙渗漏不仅会影响基坑稳定性,还会影响内衬墙的使用功能。为了解决衬墙渗漏问题,通过在内衬墙根部进行钻孔注入环氧树脂的方式达到堵漏效果。详细介绍了钻孔注入环氧树脂的堵漏方法,包括钻孔位置、孔径和深度的设定,环氧树脂的选用和注入方法等。通过该方法验证了钻孔注入环氧树脂堵漏的方式可行。In the process of foundation pit construction,due to the influence of groundwater pressure,the problem of lining wall leakage often occurs.The leakage of lining wall will not only affect the stability of foundation pit,but also affect the function of lining wall.In order to solve the leakage problem of lining wall,the plugging effect is achieved by drilling and injecting epoxy resin into the root of lining wall.This paper introduces in detail the plugging method of hole injection epoxy resin,including the setting of hole position,hole diameter and depth,the selection of epoxy resin and injection method.Through this experiment,it is proved that the method of drilling and injecting epoxy resin is feasible.
