毛细透排水带渗滤取水对比试验
|
摘要
通过环形毛细透排水带渗管、立式毛细透排水带渗管和普通PVC渗管的渗滤取水试验,对比了在不同反滤层环境下3种渗管的集水能力和滤净能力。结果表明,在单一均质反滤层条件下,立式毛细透排水带渗管能同时兼顾集水和滤净性能,取水效果达到最优。并首次提出新型毛细透排水带渗管可用于傍河取水的渗渠取水工程,研究成果对毛细透排水带在渗渠取水工程中的应用提供了理论依据和设计参考。
Through percolation and water intake tests of annular capillary drainage infiltration pipe,vertical capillary drainage infiltration pipe and common PVC infiltration pipe,water harvesting ability and filtration efficiency of the three kinds of infiltration pipes under different filter layers were compared. Results showed that under condition of single homogeneous filter layer,the vertical capillary drainage infiltration pipe could took both water collection and filtration performance,of which water intake achieved the best. Capillary drainage infiltration pipe could be used for infiltration gallery water intake project near river was proposed firstly. Study results could provide theoretical and design references for application of capillary drain belt in infiltration gallery water intake projects.
