Superstructure grouting anchor rod device with auxetic self-reinforcing function
The invention discloses a super-structure grouting anchor rod device with an auxetic self-reinforcing function. The super-structure grouting anchor rod device comprises an auxetic super-structure shell, a sleeve, a conical head, a first connecting plate, a second connecting plate and a steel plate tray. The auxetic superstructure shell is formed by arranging unit cell elements with auxetic characteristics through space continuation, and the steel plate tray and the nut are arranged at the tail of the sleeve and are in threaded fit so that the steel plate tray can be tightly attached to the surrounding rock wall. The auxetic self-reinforcing grouting anchor rod device has the tensile expansion characteristic and expands towards the periphery when being stressed, so that the anchor rod expands in the radial direction, bond wrapping and nesting between the anchor rod and surrounding objects are enhanced, the cohesive force and friction force between the anchor rod and a grouting body are greatly improved, the pulling resistance of the structure is improved, the dead weight is light, the designability is high, and the construction cost is low. The problem that binding force and friction force disappear or are greatly reduced due to tension creep necking of the anchor rod is solved, materials are convenient to obtain, the manufacturing method is feasible, and the application prospects in the fields of civil engineering, machine manufacturing, safety protection and the like are very considerable.
本发明公开了一种具有拉胀自加固功能的超结构注浆锚杆装置，包括拉胀超结构壳体、套管、锥形头，以及第一连接板、第二连接板及钢板托盘。拉胀超结构壳体由具有拉胀特性的单胞元通过空间延拓布置形成，钢板托盘和螺母布置于套管的尾部，两者为螺纹配合使得钢板托盘紧贴于围岩壁。本拉胀自加固注浆锚杆装置具有拉伸膨胀特性，在受力时向外围膨胀，使得锚杆径向扩张，增强与周围物体的握裹与嵌套，大幅提升了锚杆与注浆体之间的粘结力和摩擦力，提高结构抗拔性能，自重轻，可设计性强，解决了锚杆由于受拉蠕变缩颈造成的粘结力与摩擦力消失或者大幅减小的问题，并且取材方便，制作方法可行，在土木工程、机械制造、安全防护等领域应用前景十分可观。
