摘要
简述大田县城西水厂供水井水源地寻找,及施工工艺和钻进方法,首先采用小口径探孔、再抽水试验、水质分析等,当各项指标均符合要求后,再进行大口径的供水井施工,达到预期水量、水质要求。该大水量供水井的找水及钻探方法,可降低风险,节约成本,提高效益。
The paper introduces the method of finding the wellhead, the construction techniques and the drilling method of the supply wells in the Chengxi Water Plant of Datian County. At first, to drill the prospecting holes by using a small-caliber drilling, and to make the pumping tests and the water quality analysis, if the indices are up to the mustard, it goes on drilling a widebore supply well, which can measure up to the proleptic water quantity and quality. The method of finding the groundwater and drilling the big-yield supply well is provided with such the advantages as risk reduction, saving cost and improving economic performance.
