摘要
波波里水电站坝基防渗工程拟采用GIN法灌浆,选取了单一水灰比的稳定性浆液,在工程区开展了试验研究,探讨了GIN法在西非地区工程应用的可行性。本文通过对GIN灌浆法试验的介绍,阐明了GIN值的确定、灌浆结束标准等技术关键点,研究成果可为非洲类似工程项目提供参考。
The GIN grouting method is proposed to be used for anti-seepage treatment in the dam foundation of Popoli hydropower station.Stable grout with single water cement ratio is selected to carry out experimental research in the project area,and the application feasibility of GIN method in West Africa region is discussed.Based on introduction of the experiment for GIN grouting method,this paper expounds the key technical points such as the determination of GIN value and grouting completion standard.The research results provide reference for similar projects in Africa.
