| 摘 要： | 混凝土防渗墙技术是在松散透水地基或土石坝(堰)坝体中以泥浆固壁连续造孔成槽,在泥浆下浇筑混凝土,形成起防渗作用的地下连续墙,在我国已使用40余年,按成槽方法可将其分为钻挖成槽防渗墙、射水成槽防渗墙、链斗成槽防渗墙和锯槽防渗墙。本文通过射水法混凝土防渗墙在沙河水库坝基防渗处理中的成功应用,进一步证明了混凝土防渗墙是进行坝基防渗处理的一种有效方法。

| Abstract: | Concrete cutoff wall refers to the technology that constructed holes are connected into channel by mud solid wall in loose permeable ground or earth dam （weir） , then concrete is poured in mud, thereby forming underground continuous wall with seepage prevention effect. The technology has been used in China for more than 40 years, which is divided into drilled excavation channel cutoff wall, water spraying channel cutoff wall, bucket chain channel cutoff wall and saw channel cutoff wall. It is further proved that concrete cutoff wall is an effective method for dam foundation seepage prevention treatment by successful application of water spraying concrete cutoff wall in Shahe Reservoir Dam Foundation Seepage Prevention Treatment. |
