Resistance-increasing energy-absorbing anchor rod
A resistance-increasing and energy-absorbing anchor rod comprises a first-stage anchoring element, a second-stage anchoring element, a third-stage anchoring element, a resistance-increasing and energy-absorbing element, a rod body, a nut and a tray. The first-stage anchoring element, the second-stage anchoring element, the resistance-increasing energy-absorbing element and the third-stage anchoring element are sequentially installed at the drill hole inserting end of the rod body. The second-stage anchoring element is fixedly matched with the rod body through a nut; the third-stage anchoring element is in limiting fit with the rod body through a nut. The second-stage anchoring element and the third-stage anchoring element are matched with the resistance-increasing energy-absorbing element, so that the supporting requirements of various severe working conditions can be met; the resistance-increasing energy-absorbing element can greatly improve the deformation capacity of the anchor rod while ensuring high anchoring force so as to adapt to disasters such as high-stress rock mass large deformation and rockburst; the coupling effect between the anchoring agent and the rod body is relieved, the interfacial strength relation of the anchor rod is established, and the purposes of structural resistance increasing slippage and large deformation of a rod body material can be achieved at the same time; the device also has the characteristics of simple structure, convenience in use and low price.
一种增阻吸能锚杆，包括第一级锚固元件、第二级锚固元件、第三级锚固元件、增阻吸能元件、杆体、螺母及托盘；第一级锚固元件、第二级锚固元件、增阻吸能元件及第三级锚固元件顺序安装在杆体的钻孔插入端；第二级锚固元件通过螺母与杆体固定配合；第三级锚固元件通过螺母与杆体限位配合。本发明通过第二级和第三级锚固元件与增阻吸能元件配合，可适应多种恶劣工况条件支护需求；增阻吸能元件可在保证高锚固力的同时，大幅度提高锚杆变形能力，以适应高应力岩体大变形、岩爆等灾害；通过解除锚固剂与杆体间耦合作用、建立锚杆界面强度关系，可实现结构增阻滑移和杆体材料大变形兼具的目的；本发明还具有结构简单、使用方便、价格低廉的特点。
