[0002] At present, during the construction of power pipeline jacking, water leakage is prone to occur at the inlet and outlet holes of the jacking shaft. Further development of water leakage will lead to a series of serious consequences such as increased pipeline settlement and ground cracking. Therefore, it is very critical to seal and stop the inlet and outlet holes of the jacking shaft.
[0003] In the related art, the commonly used methods for sealing and water-stopping the inlet and outlet openings of existing jacking shafts include the following two methods: the first method is to install a rubber water-stop flange at the opening, and use a fan-shaped steel pressure plate and embedded bolts to fix the rubber water-stop flange. Although this treatment method can temporarily solve the water leakage at the opening during the installation and acceptance stage, the problem of water leakage will recur in the subsequent use stage. At the same time, the installation of the rubber water-stop flange is inconvenient, the accuracy is difficult to control at the construction site, the positioning requirements for the jacking pipe joints are high, and it is difficult to achieve a tight fit between the joints and the rubber water-stop flange on site; the second method is to embed steel plates in the wall of the jacking shaft, weld water-stop steel plates at the embedded steel plates after the jacking is completed, and fill with fine stone concrete to seal and water-stop the opening, but on-site welding is required between the steel plates, which is inconvenient for construction, and the filled fine stone concrete is prone to shrinkage after drying, resulting in small gaps at the connection between the filled concrete and the pipeline interface, causing water leakage, and unclean surface treatment during concrete filling can easily cause water leakage in the later use stage.
[0004] Therefore, it is necessary to design a new waterproof structure for pipe jacking wells to overcome the above problems. Utility Model Content
