[0002] In the process of pipe jacking construction, in order to prevent groundwater or working mud from flowing along the pipe wall to the working well, the hole water stop device is usually arranged in the working well. Especially in the stratum rich in groundwater or underwater pipe jacking construction, the hole double water stop device is also arranged, which is used to improve the effect of hole water stop during construction period and ensure the dry operation condition of working well. However, in actual construction, due to the relatively large weight of pipe material, the center of pipe material may be offset downward during jacking, which leads to the increase of upper gap of hole and the decrease of lower gap of hole, thereby increasing the risk of upper water stop outturn failure. Or it may be possible that the pipe material floats up under the action of thixotropic mud and groundwater, which leads to the increase of lower gap of hole and the decrease of upper gap of hole, thereby increasing the risk of lower water stop outturn failure. Since the center of pipe material is offset, drilling and bolt fixing cannot be carried out, which finally leads to water leakage or slurry leakage in working well.
