关于小型排灌泵站的建设,历来多从土建的总体布置设计上和加强配套建筑物的办法上,解决排灌两用的问题,如图1所示,所费工程量较大,投资较多。为减少配套建筑物,压缩投资,今提出用变更机组布置,从而改变水流方向可同样起到排、灌两种作用。现将其办法和初步意见分述如下: With regard to the construction of small irrigation and pumping stations, the problems of dual irrigation and drainage have always been solved from the overall layout design of civil works and the means of strengthening supporting structures. As shown in Figure 1, the project cost is large and the investment is more. In order to reduce the number of supporting buildings and compress investment, it is proposed to change the layout of the aircrew so as to change the direction of the water flow. The methods and preliminary opinions are as follows:
