Design of Composite Geomembrane for Seepage Prevention of Plant Area of Third Stage Pumping Station,the General Main Line of the YRDP

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。

The design of composite geomembrane for seepage prevention of plant area of the third stage pumping station,the General Main Line of the YRDP is introduced in this paper.Two seepage prevention schemes,the composite geomembane scheme and the composite geomembrane plus seepage prevention wall scheme had been taken into account in their advantages,disadvantages and cost.The latter was recommended to be adopted as it is better than the former.In addition,some construction requirements for composite geomembrane and for seepage prevention wall are given.
