Rock cave temple top prestress tailless negative pressure filling grouting anchoring structure and anchoring method
The structure comprises an anchor rod hole and an anchor rod assembly, the anchor rod hole comprises a hole opening section and a hole body section which are communicated with each other, the hole diameter of the hole opening section is gradually reduced from bottom to top, and the anchor rod assembly comprises an anchor rod body, a wedge-shaped anchor head and a base plate. The anchor rod body is of a hollow structure, a wedge-shaped part is arranged at the anchoring end of the anchor rod body, and the wedge-shaped anchor head is matched with the wedge-shaped part; the base plate is fixed to the tail of the anchor rod body through a nut. The outer ring of the base plate is in close contact with the inner wall of the orifice section; the part, located above the base plate, in the anchor rod hole is filled with a grouting body, the part, located below the base plate, in the anchor rod hole is provided with an anchor sealing body, and the tail of the anchor rod body is completely embedded in the anchor sealing body. According to the rock cave temple anchor rod sealing device, the slurry leakage phenomenon during grouting can be prevented, the anchor rod hole is pumped to negative pressure through the vacuum pump in the grouting process so that smooth grouting can be guaranteed, the tail of the anchor rod body is completely embedded in the anchor sealing body, and the appearance of the surface of a rock cave temple cannot be changed.
本发明公开了一种石窟寺顶部预应力无尾负压填充注浆锚固结构及锚固方法，该结构包括锚杆孔和锚杆组件，锚杆孔包括相互连通的孔口段和孔身段，孔口段的孔径从下到上逐渐减小，锚杆组件包括锚杆杆体、楔形锚头和垫板，锚杆杆体为中空结构，锚杆杆体的锚固端设有楔形部分，楔形锚头与楔形部分配合；垫板通过螺母固定在锚杆杆体的尾部；垫板的外圈与孔口段的内壁紧密接触；锚杆孔内位于垫板上方的部分灌注有注浆体，锚杆孔内位于垫板下方的部分设有封锚体，锚杆杆体的尾部全部埋设于封锚体内。本发明可防止注浆时的漏浆现象，注浆过程中通过真空泵将锚杆孔抽至负压进而保证注浆顺利进行，锚杆杆体的尾部全部埋设于封锚体内，不会改变石窟寺表面外貌。
