Prestress-adjustable anchor rod
The invention provides an anchor rod with adjustable prestress. The prestress-adjustable anchor rod is applied to supporting of surrounding rock, anchor holes are formed in the surrounding rock, and the prestress-adjustable anchor rod comprises an anchor rod body, an anchor rod nut, an anchor rod tray and an anchor rod spring. The anchor rod main body is arranged in the anchor hole and comprises an anchor rod free section and an anchor rod anchoring section, and the anchor rod free section is connected to one end of the anchor rod anchoring section; the anchor rod nut is arranged at the end, away from the anchor rod anchoring section, of the anchor rod free section. The anchor rod tray is connected to the anchor rod nut; the anchor rod body is sleeved with the anchor rod spring, one end of the anchor rod spring is connected with the anchor rod body, the other end of the anchor rod spring is connected with the anchor rod tray, and prestress of a certain value is applied to the anchor rod body through the anchor rod spring. According to the prestress-adjustable anchor rod, tension of a certain value is applied to the anchor rod spring, the stability of the prestress value of the anchor rod is guaranteed, and the construction quality is improved.
本发明提供了一种预应力可调式锚杆。该预应力可调式锚杆应用于围岩的支护，所述围岩开设有锚孔，所述预应力可调式锚杆包括锚杆主体、锚杆螺帽、锚杆托盘和锚杆弹簧；所述锚杆主体设置于所述锚孔内且包括锚杆自由段和锚杆锚固段，所述锚杆自由段连接于所述锚杆锚固段的一端；所述锚杆螺帽设置于所述锚杆自由段远离所述锚杆锚固段的一端；所述锚杆托盘连接于所述锚杆螺帽；所述锚杆弹簧套设于所述锚杆主体上且一端与所述锚杆主体连接，另一端与所述锚杆托盘连接，以通过所述锚杆弹簧对所述锚杆主体施加一定数值的预应力。该预应力可调式锚杆通过对锚杆弹簧施加一定数值的拉力，保证锚杆预应力数值稳定，提高施工质量。
