摘　　要：针对田间灌溉蓄水池地下水位高,导致施工过程中机械开挖难度大、铺设复合土工膜困难和运行过程中蓄水池底浮托力大等问题,通过比选,最终选定集防渗、集水、排气、排水等技术特点为一体的单向排水复合土工膜技术为最优方案。通过降水井进行排水保证施工正常进行,采用单向排水复合土工膜防渗技术,在地下水位高时水流通过土工膜上设置的单向排水阀流入蓄水池内,地下水位低时单向排水阀自动关闭,防止逆向水流或渗漏,解决了地下水对土工膜的付托破坏作用,保证了蓄水池安全运行并保证了高效节水灌溉工程的高质量运行。In light of the considerable challenges posed by the high water table of field irrigation cisterns,including difficulties in the construction process of mechanical excavation,the laying of composite geomembranes,and the operation of the cistern bottom floatation force,among others,a set of optimal technical characteristics was ultimately selected.These included unidirectional drainage of the composite geomembrane technology and other features designed to control seepage,collect and drain water,and enhance overall performance.It is essential to ensure that drainage is conducted through the precipitation well to guarantee the normal construction process.The utilization of one-way drainage composite geomembrane seepage control technology is a crucial aspect of this process.In areas with high water tables,the geomembrane facilitates water flow through the one-way drainage valve into the cistern.This valve is designed to automatically close when the groundwater level reaches a certain point,preventing any reverse water flow or leakage.To prevent the reverse water flow or leakage,to solve the groundwater issue on the geomembrane,and to prevent the destructive effect of the cistern,it is essential to ensure the safe operation of the cistern and the high-efficiency water-saving irrigation project.
