Rock cave temple top prestress tailless hole wall notch groove hollow grouting anchoring assembly and anchoring method
The invention discloses a grotto temple top prestress tailless hole wall notch groove hollow grouting anchoring assembly and an anchoring method. The anchoring assembly comprises an anchor rod body, a base plate and a passive triggering cutter drill. After the anchor rod body is placed into the anchor rod hole, the tail of the anchor rod body is located in the anchor rod hole, and the anchor rod body is of a hollow structure and is used for grouting; the passive triggering cutter drill is arranged on the outer side of the anchor rod body, a triggering device is further arranged in the anchor rod body and used for triggering the passive triggering cutter drill to extend, the anchor rod body is rotated to cut the inner wall of an anchor rod hole, a cutting groove is formed, the passive triggering cutter drill is embedded into the cutting groove, and anchoring force is provided for the anchor rod body. The base plate is fixed to the tail of the anchor rod body through a nut, and the outer ring of the base plate makes close contact with the inner wall of the anchor rod hole and is used for preventing slurry leakage during grouting. The integrity and anchoring strength of the anchoring structure can be improved, the slurry leakage phenomenon during grouting is prevented, the tail of the anchor rod body is completely embedded in the anchor sealing body after construction, and the appearance of the surface of the grotto temple cannot be changed.
本发明公开了一种石窟寺顶部预应力无尾孔壁刻槽中空注浆锚固组件及锚固方法，该锚固组件包括锚杆杆体、垫板和被动触发刀钻；所述的锚杆杆体放入锚杆孔后锚杆杆体的尾部位于锚杆孔内，锚杆杆体为中空结构，用于注浆；所述的被动触发刀钻设置在锚杆杆体外侧，锚杆杆体内还设有触发装置，用于触发被动触发刀钻伸长，通过旋转锚杆杆体切割锚杆孔内壁并形成切槽，使被动触发刀钻嵌入切槽内，为锚杆杆体提供锚固力；所述的垫板通过螺母固定在锚杆杆体的尾部，垫板的外圈与锚杆孔内壁紧密接触，用于防止注浆时漏浆。本发明可提高锚固结构的整体性和锚固强度，防止注浆时的漏浆现象，施工后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。
