西溪河联补电站引水隧洞缺陷处理固结灌浆施工

摘要

结合西溪河联补水电站引水隧洞工程的地质条件，从灌浆强度指标设计、施工控制标准、工艺流程、质量检查四方面，阐述了水泥浆液固结灌浆施工技术，达到了封闭引水隧洞周边岩体渗水裂隙和通道、增强围岩抗渗性与稳定性的目的。%Combining with diversion tunnel engineering geology conditions of Xixi river Lianbu hydropower station,starting from four aspects of grouting strength index design,construction control criteria,technological procedures and quality examination,the paper describes cement slurry consolidation grouting technologies. As a result,it achieves the goals of closing diversion tunnel surrounding rock seepage cracks and channels and strengthening surrounding rock anti-seepage and stability performance as well.
