一种多囊扩体锚杆的快速钻扩装置
By designing a rapid drilling and reaming device for multi-bladder reaming anchors, the problem of fixed number and spacing of bladders was solved, enabling flexible adjustment of the number of bladders and convenient replacement of drill bits. This improved the adaptability and construction efficiency of the anchoring structure and met the high-efficiency anchoring requirements under complex geological conditions.
