Construction Technology of Slope Reinforcement in Shilong Power Station of Songjianghe

摘要:

在松江河石龙电站边坡加固工程中，采用小直径抗滑桩加锚杆的桩锚联合支护体系，替代单纯的大直径抗滑桩，解决了陡峭边坡大型设备无法使用问题。采用潜孔锤跟管钻进工艺，解决了人工填石层钻孔坍塌及不能用水做循环介质的问题。介绍了该边坡治理方案及其施工技术，对陡峭边坡灾害治理工程有实用参考价值。

Abstract:

Combined pile-anchor supporting system with small diameter anti-slide pile and anchor rod was adopted for slope reinforcement in Shilong power station of Songjianghe, which replaced simple large diameter anti-slide pile and realized the application of large equipment in steep slope. Borehole collapsing and water as circulating medium in artificial backfilled stone layer were solved by DTH hammer drilling technology. The paper introduced the slope reinforcement scheme and construction technology in Shilong power station of Songjianghe.
