Air bag plugging device and plugging method for plugging shield tunnel
The invention belongs to the technical field of shield tunnel construction, and discloses an air bag plugging device for plugging a shield tunnel and a plugging method.The air bag plugging device comprises a tunnel segment and further comprises a shell, a roller set, an air bag, a plurality of first supporting mechanisms and two second supporting mechanisms; the air bag is inflated to be expanded and attached to the inner wall of the tunnel segment in a sealed mode, so that the shield tunnel is blocked. The first supporting mechanisms are arranged on one side of the downstream face of the contact end of the air bag and the shell and used for supporting and fixing the air bag, dislocation and sliding of the air bag are restrained, and the plugging efficiency is improved; one end of the second supporting mechanism abuts against the interior of a notch in the downstream face of the shell, and the other end of the second supporting mechanism abuts against the interior of a segment hand hole, so that the fixing effect is achieved, the device is prevented from retreating and sliding under water pressure, and the plugging effect and the anti-sliding performance are improved.
本发明属于盾构隧道施工技术领域，且公开了一种用于封堵盾构隧道的气囊封堵装置及封堵方法，所述气囊封堵装置包括隧道管片，还包括壳体、滚轮组、气囊、若干第一支撑机构以及两组第二支撑机构；通过向所述气囊内部充气使其扩张并与所述隧道管片内壁密封贴合，以实现封堵盾构隧道。本发明通过在气囊与壳体接触端背水面一侧设有若干第一支撑机构，用于抵撑气囊固定，抑制气囊的错位和滑动，提高封堵效率；第二支撑机构一端抵撑于壳体背水面的槽口内，另一端抵撑于管片手孔内，达到固定效果，防止装置在水压下产生后退滑移，提高封堵效果和抗滑移性能。
