万家寨引黄工程总干线三级泵站原防渗方案用高喷防渗墙防渗 ,该方案起临时围堰和永久防渗作用 ,投资较大。随着工程进展 ,用复合土工膜替代高喷防渗墙较为合理。本文对各防渗方案的设计思路进行了论证。实际施工情况证明所推荐的替代方案是合理可行的 Wanjiazhai Yellow River Diversion Project main pumping station three anti-seepage program with high seepage cutoff seepage prevention, the program from the temporary cofferdam and permanent seepage, a larger investment. With the progress of the project, it is more reasonable to replace the high-jet cutoff wall with a composite geomembrane. This paper demonstrates the design ideas of various seepage control schemes. The actual construction proved that the proposed alternative is reasonable and feasible
