谈到灌溉技术,传统的地面渠道灌溉系统为大家所熟识,干、支、斗、农、毛各级渠道以及渡槽、隧洞、水闸、桥涵等渠系建筑物更是耳熟能详,而管道输水灌溉技术在渠灌区的应用较少,还没有形成完整的理论体系。文章从基层工程实践中大胆探索,提出管道输水灌溉技术在渠灌区应用的新概念,总结了三种管道输水灌溉模式,为低压管道输水灌溉增添了新的内涵。 When it comes to irrigation technology, the traditional surface channel irrigation system is familiar to all. Channels at all levels such as stem, branch, bucket, agriculture and wool as well as aqueducts, tunnels, sluices, bridges and culverts and other canal structures are more familiar to you. Pipeline irrigation There are few applications of technology in the drainage irrigation area, and a complete theoretical system has not been formed yet. The article boldly explores from the grassroots engineering practice and puts forward the new concept of the application of pipe-conveying irrigation technology in the irrigation district. Three types of pipe-feeding irrigation modes are summarized, which adds new connotation to the transmission of low-pressure pipelines.
