本文首先分析了珠江三角洲河口网河区原有排灌条件,确定兴建电力排灌工程的必要性,并论述了电力灌溉可按照完全满足用水要求的高标准设计,而电力排涝则宜于采用较低标准。关于排灌站的布置,建议以划分小区分散建站为主要形式,并应注意排水与灌溉相结合,流动抽水机与固定站相结合,电力排灌与其他水利工程结合的必要性与可能性等。 This paper first analyzes the original irrigation and drainage conditions in the estuary of the Pearl River Delta and determines the necessity of constructing electric irrigation and drainage projects and discusses the high standard design of electric irrigation that meets the requirements of water use completely. . With regard to the layout of irrigation and drainage stations, it is suggested to disperse and build stations as the main form of division, and should pay attention to the combination of drainage and irrigation, the combination of mobile pumping stations and fixed stations, the necessity and possibility of combining electricity drainage and irrigation with other water projects.
