不良气候环境下快速铺设复合土工膜施工技术

On the Construction Technique of Rapidly Paving Composite Geomembrane under Bad Weather Environment Condition

复合土工膜作为新型土工防渗材料,目前国内较为成功的铺设施工案例,基本上都是一次铺设面积较小且气候环境多为常温无风条件。根据山西万家寨引黄耿庄水库工程实际情况,针对一次铺设面积大、气候环境恶劣等问题,经过施工技术人员对复合土工膜施工工艺进行研究和总结,最终形成了一套完整的针对不良气候环境下快速铺设复合土工膜的施工工艺,经过工程的实际应用证明,效果良好。

The composite geomembrane is a new kind of seepage control material. At present, the successful construction cases to pave it in our country usually are completed under such conditions that one-time paved area is not very large and the air temperature is common without wind. According to the actual situation of constructing the Gengzhuang Reservoir and in view of the issues that one-time paved area is larger and the climate environment is adverse, through study and summarization on the technique of paving composite geomembrane by construction workers, a set of overall rapid paving technique being aimed at adverse climate environment is generated. The practice of applying this technique indicates that its construction effect is good.
