渠道防渗防冻胀衬砌技术研究——以杨陵渠灌农业高效用水模式试验区为例

Research on the Optimum Styles of Canal Lining for Seepage Control and Freezing Prevention

针对试验区水资源、土壤、气候的特点和工程建设条件 ,通过对防渗材料、伸缩缝填料和施工技术的筛选集成 ,选择预制安砌 U形槽 ,全 U形现浇、板膜复合等 5种渠道衬砌模式进行研究和示范 ,分析了各方案防渗效果和工程造价 ,提出 U型衬砌机现浇渠道为试验区的最佳防渗衬砌形式。

According to water resource, soil and climate in Yangling testing and demonstration area , five styles of canal lining were selected for study and extending. Through analysing the effect of seepage control and cost of all styles of canals in testing and demonstration ground, concrete U groove constructed by U shaped canal lining machine is considered to be the best style of canals in the prevention of seepage and freezing.
