摘要
从北京市丰台地区第四系潜水含水层的地层岩性结构入手,分析了传统供水管井成井工艺存在的问题,详细研究介绍了孔壁坍塌填砾法成井工艺在实际水井工程项目中的成功应用,取得了较好的增加水井出水量的效果。
The article is based on the stratum lithology structure of the Quaternary phreatic aquifer in Fengtai district of Beijing city and analyzes the existing problems of the drilling technology of the traditional flow pipe wells,then makes a general introduction on successful application of the drilling technology of the method of gravel-filled in borehole collapse on practical well projects,which gets better effects of increasing water yield.
