十三陵抽水蓄能电站地下工程断层节理发育 ,地质条件复杂 ,塌方频繁 .2 # 高压管道上斜段导井在穿越 f2 0 大破碎带时发生特大塌方 ,因塌穴位于高压管道斜井上 ,处理难度大 .经过多种处理方案的实践 ,证明“地表钻孔 ,下堵上灌 ,加压注浆”处理斜井塌方比较有效 ,工程处理是成功的
The underground section of the Shisanling Pumped Storage Power Station is developed with complicated geological conditions and complicated landslides, and the collapsed hole is located on the inclined shaft of the high-pressure pipeline when the upper section guide shaft of the No. 2 high-pressure pipeline crosses the f20 large crushing zone. It is very difficult to deal with it.After the practice of many treatment schemes, it is proved that “surface drilling, plugging and grouting under pressure”
