摘要
在边坡治理工程中常采用预应力锚索,但传统的锚索钻机在钻掘硬岩时,进尺非常缓慢,而且根管难以拔出。通过采用高效的履带式双管双动跟管钻机在滑坡体上进行锚索成孔,大大提高了成孔效率和下锚质量,节约了锚索成孔时间,为滑坡治理赢得了宝贵的时间。同时,总结和分析了其与传统锚杆钻机的优缺点,为提高滑坡治理效率提供了新思路。
The author uses a high-efficiency crawler-type double-pipe double-action follow-pipe drilling rig to make holes for anchor cables on the landslide body,which greatly improves the hole-forming efficiency and the quality of anchoring.Summarized and analyzed its advantages and disadvantages compared with traditional bolt drilling rigs,and provided new ideas for improving the efficiency of landslide control.
