Rock cave temple top prestress tailless back pressure filling grouting anchoring structure and anchoring method
The invention discloses a grotto temple top prestress tailless back pressure filling grouting anchoring structure and method. The structure comprises anchor rod holes and anchor rod assemblies. The anchor rod hole comprises an orifice section and a hole body section which are communicated with each other; the anchor rod assembly comprises an anchor rod body, a wedge-shaped anchor head, a base plate and an exhaust pipe, a wedge-shaped part is arranged at the anchoring end of the anchor rod body, 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 makes close contact with the inner wall of the orifice section, one end of the exhaust pipe is fixed to the anchoring end of the anchor rod body, and the other end of the exhaust pipe makes close contact with the orifice section. The other end of the exhaust pipe penetrates through the base plate; 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. The grout leakage phenomenon in the grouting process is prevented through tight contact between the base plate and the inner wall of the hole opening section, the tail of the anchor rod body is completely embedded in the anchor sealing body, and the appearance of the grotto temple surface cannot be changed.
本发明公开了一种石窟寺顶部预应力无尾反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；所述锚杆孔包括相互连通的孔口段和孔身段；所述的锚杆组件包括锚杆杆体、楔形锚头、垫板和排气管，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，排气管的一端固定在锚杆杆体的锚固端，排气管的另一端贯穿垫板；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。本发明通过垫板与孔口段的内壁紧密接触防止注浆过程的漏浆现象，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。
