摘要
本文研发了一种新型完全可回收锚杆,内容包括完全可回收螺旋锚杆、阶梯钻杆、钻机、扭矩倍增器。井下试验表明:该锚杆不使用锚固剂,锚固强度及施工效率不低于当前普通锚杆,锚杆的复用率达90%以上。
In this paper,a new fully recyclable bolt is developed,including fully recyclable screw bolt,stepped drill pipe,drilling rig and torque multiplier.The underground test shows that the anchor does not use anchoring agent,the anchoring strength and construction efficiency are not lower than the current ordinary anchor,and the reuse rate of the anchor is more than 90%.
