Anchor rod reinforcing structure for side slope and anchoring method
The invention relates to the technical field of electric power engineering structure design, in particular to a slope anchor rod reinforcing structure and anchoring method.The slope anchor rod reinforcing structure comprises a reinforcing mechanism which comprises an anchor rod, a cutting assembly arranged on the anchor rod and a tray arranged on the anchor rod in a sleeving mode; the cutting assembly comprises a drill bit and a spiral blade, the drill bit and the spiral blade are driven by rotation of the anchor rod to drill and broach a slope and form a stepped hole, the anchor rod generates the radial expansion characteristic and axial straightening deformation through relative sliding of the cone and the sleeve, and then large constant resistance is generated. By means of the negative Poisson's ratio structure effect, the double effects of annular expansion and radial extension of the sleeve are achieved, the requirement for large deformation can be met, the anchoring effect of the anchor rod can be greatly improved, the stability of the power transmission tower foundation is protected, and therefore various rock-soil body geological disasters of the power transmission tower foundation slope are prevented and controlled.
本发明涉及电力工程结构设计技术领域，尤其是一种边坡用锚杆加固结构及锚固方法，包括加固机构，其包括锚杆，设于所述锚杆上的切削组件，以及套设在所述锚杆上的托盘；所述切削组件包括钻头和螺旋刀片，通过锚杆转动带动钻头和螺旋刀片在边坡上的钻孔和扩孔，开成阶梯孔，锚杆通过锥体与套管的相对滑动，产生径向膨胀特性和轴向回直变形，进而产生有很大的恒阻力，通过负泊松比结构效应使得套管环向膨胀和径向伸长的双重作用，不仅可以满足大变形的要求，还可以大大地提高、锚杆的锚固作用，保护输电塔基础的稳定性，进而防治输电塔基础边坡各种岩土体地质灾害的发生。
