摘要
节水灌溉是干旱地区水利建设的重点 ,目前低压管灌在井灌区应用很多 ,但是在自流灌区还应用很少 ,而发展自压管道灌溉亦是自流灌区发展节水灌溉的一项重大革新 ,为研究解决自流灌区大面积推广管灌的技术问题 ,提出了在自流灌区的节水改造中发展自压管道灌溉。
This paper analyzes the existing problems in the gravity-flow irrigation district,illustrates the application of low-pressure pipeline water-conveyance irrigation technique in the design of water-saving improvement of the irrigation district, and summarizes the advantage of the technique by comparing it with the canal seepage-prevention technique. Yangwuhe irrigation district is taken as an example.
