渠道输水在我国农田灌溉中一直扮演重要角色,传统的土渠渠道输水效果不是很好,渗漏严重,导致水利用系数大幅降低,有效灌溉面积不断减少,水资源严重浪费。利用防渗渠道输水可以很好的解决这个问题,效果极佳,近年来应用极广。本文主要讨论了开封市引黄灌区的灌溉防渗,根据黄河流域特有的水利特点进行深入讨论,并对主要的施工技术进行详细阐述。

Channel water transport has played an important role in farmland irrigation in our country. The effect of water delivery in traditional canal is not very good, and the seepage is serious. As a result, the coefficient of water utilization is greatly reduced, the area of ​​effective irrigation is decreasing, and the water resources are seriously wasted. The use of impervious channel water can be a good solution to this problem, the effect is excellent, extremely wide range of applications in recent years. This paper mainly discusses the irrigation seepage prevention in the Yellow River Diversion Irrigation Area in Kaifeng City. Based on the peculiar water features of the Yellow River Basin, the paper discusses in depth the main construction techniques.
