Side slope anchoring device for municipal engineering and construction method of side slope anchoring device
The invention relates to the technical field of anchor rod construction equipment, in particular to a side slope anchoring device for municipal engineering and a construction method thereof, the side slope anchoring device comprises an anchor pipe, a driving disc and a driving rod, the driving disc is rotatably mounted in the anchor pipe, a plurality of slotting pricking needles are hinged to the driving disc in the circumferential direction, and first through holes corresponding to the slotting pricking needles one to one are formed in the anchor pipe. In the initial state, the slotting pricking needle is contained in the anchor pipe, and one end of the slotting pricking needle is located in the first through hole. During use, an anchor pipe is placed in an anchor rod hole, and the driving disc is driven to rotate through the driving rod, so that the slotting pricking needles are driven to pierce outwards. When the slotting pricking needles pierce outwards, irregular fan-shaped grouting grooves are formed in rock soil nearby the interior of the anchor rod hole, so that mortar can be injected into the rock soil in the anchor rod hole during grouting, and the pulling resistance of the anchor pipe is enhanced. The technical scheme is mainly used for municipal engineering slope reinforcement, and the problem that mortar is difficult to enter rock soil nearby a drill hole during grouting of an existing full-length bonding type anchor rod is solved.
本发明涉及锚杆施工设备技术领域，具体涉及一种市政工程用边坡锚固装置及其施工方法，包括锚管、驱动盘、驱动杆，驱动盘转动安装在锚管内，驱动盘上沿圆周方向铰接有多个开槽刺针，锚管上开设有与开槽刺针一一对应的第一通孔。初始状态时开槽刺针收纳在锚管内，开槽刺针的一端位于第一通孔内。使用时将锚管放入锚杆孔内，通过驱动杆带动驱动盘转动，从而带动开槽刺针向外刺出。由于开槽刺针向外刺出时将锚杆孔内附近的岩土划出不规则扇形的注浆槽，从而使得注浆时，砂浆能够注入锚杆孔内的岩土内，增强了锚管的抗拔能力。该技术方案主要用于市政工程边坡加固，解决现有的全长粘接型锚杆注浆时，砂浆难以进入钻孔内附近的岩土内部的问题。
