摘　　要：永舒榆灌区原有的配套工程不完善,几乎没有防渗措施,田间节水工程滞后,水利用率低,影响灌区效益的发挥。详细介绍复合土工膜结合PP纤维混凝土防渗技术的原理及其在灌区节水灌溉续建工程中的施工工艺。实践证明,该技术具有良好的防渗效果。Yongshuyu Irrigation Project is not perfect in the original package,mainly with no anti-seepage measures.The field watersaving projects are lagging behind,resulting in irrigation water losses and low water productivity and high water consumption per unit area,affecting the efficiency of the irrigation facilities.This paper deals with the irrigation project of Yongshu-yu.The author expands on the principle and applications of complex geomembrane and PP fibre concrete used in the Seepage Prevention Project of Yongshuyu Irrigation System.Practice has shown that this technique can achieve good effect in seepage prevention.
