灌区内闸门漏水现象是相当普遍的,由于严重的漏水而影响计划用水的正确实施,大量浪费的水量引起地下水升高使土壤恶化。河南人民胜利渠灌区的群众及管理人员几年来在工作中创造了一些低水头闸门防止漏水的措施,效果都很好。兹介绍于下,供备地灌区参考。(1)橡皮止水带防漏:一般安装在水头较高的大,中型闸门上,如渠首闸、总干节制闸等。最初是采用单层橡皮(图1),但由于单层橡皮与闸墙接触不够紧密.仍有漏水,后改为双层折叠式安装(图2),效果较前提高。
Water leakage from the gates in the irrigation area is quite common. Due to serious leakage, the correct implementation of planned water use resulted in a large amount of wasted water causing the groundwater to deteriorate to deteriorate the soil. Henan people Victory Canal irrigation areas of the masses and managers over the past few years at work to create some low head gate to prevent water leakage measures, the effect is very good. It is introduced below, for the preparation of irrigated area reference. (1) rubber water-stop leak-proof: Generally installed in the head of the high, medium-sized gate, such as the first gate, Gansu Governor gate. Initially, a single layer of rubber was used (Figure 1), but the single layer of rubber was not in close contact with the gate wall and there was still leaking water, which was later changed to double-layer folding installation (Figure 2).
