在城市轨交建设中,区间隧道多采用盾构法施工,盾构始发、到达过程中,隧道洞门渗漏现象经常发生,处理不好会给工程造成很大的影响。由于造成洞门渗漏的原因众多、且难以直接控制等,往往很难达到预定效果,导致工程进度严重滞后,形成质量、安全隐患,造成巨大的投资浪费。因此,在洞门封堵 In the construction of rail transit in cities, the tunnels are mostly constructed by shield method. During the process of shield initiation and arrival, the leakage of tunnel gates often occurs, and the poor handling will greatly affect the project. Due to many reasons that cause the leakage of Dongmen, and it is difficult to directly control, it is often difficult to achieve the desired results, leading to serious delays in the progress of the project, the formation of quality and safety risks, resulting in huge investment waste. Therefore, blocking the door
