选择和使用简单而有效的隔离止水方法,是水文钻孔施工中的重要环节之一。自一九六三年以来,我队遵照毛主席“独立自主、自力更生”的教导,组成了工人、干部、技术人员的三结合小组,对基岩深孔多含水层的隔离止水方法进行了研究,试制了胶塞隔水器。十几年来,先后在北票、平庄、南票、阜新以及沈阳等煤田勘探和工程地质勘探中广泛使用。实践证明,胶塞隔水器隔水性能良好,并可简化钻孔结构,节省套管、缩短工
The selection and use of a simple and effective method of isolated water stop is one of the most important aspects of hydrological drilling. Since 1963, in line with Chairman Mao’s “Independent and Self-reliance” teaching, our team has formed a three-in-a-small group of workers, cadres and technicians to study the isolation and sealing method for multi-aquifer aquifers in bedrock. , Trial production of rubber stopper. For more than a decade, it has been widely used in coal prospecting and engineering geological exploration in Beipiao, Pingzhuang, Nanpiao, Fuxin and Shenyang. Practice has proved that rubber stopper water separator good performance, and can simplify the drilling structure, saving casing, shortening the work
