Energy dissipation and seismic mitigation anchor rod and construction method thereof
The invention provides an energy dissipation and seismic mitigation anchor rod and a construction method thereof. The seismic mitigation anchor rod comprises an anchor rod system and an energy dissipation and seismic mitigation system, wherein the anchor rod comprises a rod body, an anchor and a base plate; the anchor and the base plate fix the front end of the rod body on a retaining structure and fix the rear end of the rod body in the stratum through slurry; the energy dissipation and seismic mitigation system comprises a hydraulic cylinder, a spring, a piston, top spreader bars, viscous liquid and an orifice; the hydraulic cylinder is full of the viscous liquid; the top spreader bars symmetrically distributed on the side walls of the front and rear ends of the hydraulic cylinder; the spring is sleeved on a piston rod; the piston is sleeved in the hydraulic cylinder; the piston rod is coaxially connected with the rod body through a sleeve; under the action of an earthquake, the anchor rod generates repeated pulling compressive deformation along with the earthquake reciprocating force, and energy loss is caused by the spring, resistance of the viscous liquid and attached anchoring force of the top spreader bar; and after the earthquake is finished, the anchor rod is automatically reset under the action of compression liquid and the spring. The anchor rod is simple in structure, feasible in technology and easy to construct, and has favorable damping performance, anchoring performance and long-term service performance.
本发明提供一种耗能减震锚杆及其施工方法，该减震锚杆包括锚杆系统和耗能减震系统；锚杆包括杆体、锚具和垫板；锚具和垫板将杆体前端锚固于挡土结构上，后端通过浆体锚固于地层中。耗能减震系统包括液压缸、弹簧、活塞、顶扩杆、粘滞液体和节流孔；缸内充满粘滞液体，顶扩杆在液压缸前后两端侧壁对称分布，弹簧套在活塞杆上，活塞套于液压缸内，活塞杆与杆体通过套筒同轴连接；地震作用下，锚杆随着地震往复力而产生反复的拉压变形，弹簧、粘滞液体阻力和顶扩杆附加锚固力会进行能量损耗；地震结束后，在压缩液体和弹簧作用下自动复位；本发明结构简单、技术可行、组装便捷、施工容易，具有良好的减震、锚固和长期服役性能。
