中文摘要:由于矩形抗滑桩自身抵抗弯矩最优的特殊性质,在岩土工程施工设计时被广泛采用。常规的矩形抗滑桩开挖只能采用人工开挖,效率低下,周期长,安全隐患大。在三星滴水岩滑坡路段恢复整治工程实践中,采用旋挖钻机来辅助开挖,极大地提高了开挖效率和缩短了人工井下作业周期,减少了安全隐患和风险,为以后类似项目安全和高效地施工提供了较好的参考价值。

The application of the rotary drilling rig in rectangular anti-slide piles in rock formation while manual dugging
Abstract:Rectangular anti-slide pile is widely used in geotechnical engineering construction design because of its special property of optimal bending moment resistance. Conventional rectangular anti-slide pile excavation can only be carried out by manual excavation, which has low efficiency, long period and great safety risks. In the practice of recovery and control engineering of Sanxing Dishui Rock landslide section, the author adopted rotary drilling machine to assist excavation, which greatly improved the excavation efficiency and shortened the manual underground operation cycle, reduced the hidden danger and risk, and provided a good reference value for the safe and efficient construction of similar projects in the future.
