泰安抽水蓄能电站上水库采用复合土工膜防渗技术,这种防渗方案在国内已建和在建以及正在进行前期工作的抽水蓄能电站中尚无先例,研究其施工技术意义重大。复合土工膜施工程序为:施工准备,现场试验,碎石找平层施工,土工布铺设,粗砂下垫层施工,复合土工膜施工,粗砂上垫层施工,石渣保护层施工,竣工验收。 The use of composite geomembrane seepage control technology in the upper reservoir of Taian Pumped Storage Power Station has no precedent for this anti-seepage program in domestic pumped storage power stations under construction and ongoing work. It is of great significance to study its construction technology. The construction process of composite geomembrane: construction preparation, field test, gravel leveling construction, laying of geotextiles, construction of coarse sand underlay, construction of composite geomembrane, construction of coarse sand cushion, gravel protective layer construction, completion and acceptance.
