高聚物复合堵水浆材在岩溶地区深孔帷幕灌浆中的应用

Application of high polymer composite water blocking slurry in deep hole curtain grouting in the karst area

以云南省某水电站右岸抗力体涌水处理工程为背景,详细介绍了深孔帷幕灌浆遇到溶腔大流量高压高流速涌水的特殊情况后引进高聚物复合堵水浆材(C-GT堵水浆材)进行处理的技术特点及施工过程。为岩溶地区工程涌水处理提供了新的材料选择及处理方式,可对类似工程提供借鉴。

Based on the background of water surge treatment for the right bank support body of a hydropower station in Yunnan Province, this paper introduces treatment of the special conditions of high-volume, high-pressure and high-flow water inrush encountered during deep hole curtain grouting with high-polymer composite water-blocking slurry(C-GT water-blocking slurry), which provides new material selection and treatment methods for the gushing water treatment in the karst area, and also reference for similar projects.
