山嘴站干渠渠道防渗施工设计方案比选分析

Analysis on Comparison and Selection of Anti-seepage Construction Design Schemes of Main Canal at Shanzui Station

辽宁山嘴站引水干渠,沿线地层均为粉土及细(粉)砂,针对渠道存在的问题进行防渗改建,对不同渠道衬砌方案比较分析,从结构性能、投资、施工三方面进行比较,提出采用"复合土工膜+双层砼板"的综合防渗方法进行改造。施工效果表明,防渗效果明显,提高了水资源的利用率。

In order to solve the problems existing in the channel, the paper analyzes the lining schemes of different channels and compares them from the aspects of structure performance, investment and construction, and puts forward the countermeasures to improve the construction quality of the channel. The use of ＂composite geomembrane ＋ double concrete plate,＂ the integrated anti-seepage methods to transform. Construction results show that seepage effect is obvious, improve the utilization of water resources.
