我们在抽水试验中利用了人力消防水泵及浮标水位计,消防水泵一般城市里都有,可以借用,解决了广大农村和山区缺乏动力设备,同时也解决了人力抽水水量不正常的困难,保证抽水试验工作的进行。这种方法的优点是简便、经济、效果良好(与有机械动力效果同),不用水龙头,适于较小孔径(在小孔径抽水孔旁设一测水管观测水位),现介绍于后,对抽水量要求不大的地方可参考。
In the pumping test, we used the manpower fire pump and buoy water level gauge. The fire pump is generally available in cities and can be used to solve the lack of power equipment in rural and mountain areas. It also solves the problem of abnormal pumping water and guarantees pumping. The conduct of the test work. The advantages of this method are simplicity, economy, and good results (the same as with mechanical power). Without taps, it is suitable for smaller apertures (a water pipe is placed next to the small aperture to observe the water level). The place where the amount of pumping water is not required can be referred to.
