Negative pressure drainage film bag grouting anchor rod and negative pressure drainage anchoring construction method
The invention discloses a negative pressure drainage film bag grouting anchor rod and a negative pressure anchoring construction method.The negative pressure drainage film bag grouting anchor rod comprises a middle negative pressure suction part, a head end drainage plugging part and a tail end drainage reinforcing part, and the middle negative pressure suction part comprises a middle negative pressure suction rod and a negative pressure suction drainage pipe; the negative pressure suction drainage pipe is communicated with an inner cavity of the middle negative pressure suction rod; the head end drainage plugging part comprises a head end sealing connector and a head end drainage body, and the head end drainage body directionally expels underground water through grouting expansion deformation; the tail end drainage reinforcing part comprises a tail end connecting assembly and a tail end drainage body, and the tail end drainage body is connected to the tail end connecting assembly and can directionally expel underground water through grouting expansion deformation. According to the negative-pressure anchoring construction method, the negative-pressure drainage film bag grouting anchor rods are adopted for negative-pressure drainage and anchoring, the drainage efficiency of the deep water-rich unconsolidated stratum can be improved, meanwhile, surrounding rock can be timely and effectively reinforced, the strength of the surrounding rock is maintained, and the stability of tunnel excavation is guaranteed.
本发明公开了一种负压排水膜袋注浆锚杆和负压锚固施工方法,负压排水膜袋注浆锚杆包括中部负压抽吸部、首端排水封堵部和尾端排水加固部，中部负压抽吸部包括中部负压抽吸杆和负压抽吸排水管，负压抽吸排水管与中部负压抽吸杆的内腔连通；首端排水封堵部包括首端密封连接头和首端排水体，首端排水体通过注浆膨胀变形定向驱离地下水；尾端排水加固部包括尾端连接组件和尾端排水体，尾端排水体连接在尾端连接组件上，并能通过注浆膨胀变形定向驱离地下水。负压锚固施工方法采用负压排水膜袋注浆锚杆进行负压排水和锚固，能提高深度富水松散地层的排水效率，同时能及时有效的对围岩进行加固，维持围岩的强度，保证隧洞开挖的稳定性。
