通过在黄河滩地利用大口径水平辐射井取水试验 ,探讨了解决在黄河下游细颗粒含水层合理开发地下水难题的关键技术和方法。实验证明 ,大口径水平辐射井可以大幅度提高单井出水量 ,降低了以黄河水为供水水源的取水成本
The key technologies and methods to solve the problem of rational exploitation of groundwater in the fine-grained aquifer in the lower Yellow River are discussed through water intake experiments using the large-diameter horizontal radiation wells in the Yellow River beach. Experiments show that large-caliber horizontal well can significantly increase the single-well water discharge and reduce the cost of taking water from the Yellow River as the water supply source
