Prestressed large-deformation anchor rod
The prestressed large-deformation anchor rod comprises a nut (1), a rod body diameter increasing section (3) and a rod body diameter conventional section (4), the diameter of the rod body diameter increasing section (3) is larger than that of the rod body diameter conventional section (4), and the nut (1) is arranged at the tail of the rod body diameter increasing section (3). The rod body diameter increasing section (3) and the rod body diameter conventional section (4) are both of a solid structure and are integrally formed. The surface of the rod body diameter increasing section (3) is smooth; and threads (5) are arranged on the surface of the rod body diameter conventional section (4). The prestressed large-deformation anchor rod is simple in structure and low in cost, generates large deformation under the condition that certain bearing capacity is kept, and cannot be damaged under large deformation of surrounding rock, so that the rock mass with large deformation can be continuously and effectively supported.
本发明公开了一种预应力大变形锚杆，包括螺母（1）、杆体直径增大段（3）、杆体直径常规段（4），所述杆体直径增大段（3）的直径大于杆体直径常规段（4）的直径，所述螺母（1）设置在杆体直径增大段（3）的尾部上，所述杆体直径增大段（3）、杆体直径常规段（4）均采用实心结构且一体成型；所述杆体直径增大段（3）的表面光滑；所述杆体直径常规段（4）的表面设置有螺纹（5）。本发明的预应力大变形锚杆结构简单、成本低，在保持一定承载力的情况下产生较大变形、不会在围岩大变形下发生破坏、从而可以继续有效支护已产生大变形的岩体。
