在水文地质勘探中,当需要进行分层抽水时,止水是一项非常重要的工作。如果没有一种可靠的止水方法,不论是水量或水质都得不到正确的结果。关于黄豆止水的问题,我们曾按照1957年水文地质工程地质杂志第10期上张治平同志介绍的方法进行了几次的实验与分析研究。发现单纯的黄豆颗粒不能完全止住水,同时得出用干黄豆粉拌干粘土粉末止水的方法, In hydrogeological exploration, stopping water is a very important task when stratified pumping is required. Without a reliable method of stopping water, neither the amount of water nor the quality of the water will give correct results. Regarding the problem of water stoppage of soybeans, we conducted several experimental and analytical studies in accordance with the method introduced by Comrade Zhang Zhiping on the 10th issue of the Journal of Hydrogeology and Engineering Geology in 1957. It was found that pure soy bean particles could not completely stop the water, and at the same time, a method of using dry soy flour mixed with dry clay powder to stop water was found.
