Circular jacking pipes are also assembled, and their pipe sections must be prefabricated first. Prefabrication can be carried out in the factory on an assembly line. Concrete jacking pipe sections are produced through customized molds. After decades of development, the existing production molds have low production efficiency and low turnover efficiency, especially during the concrete pouring and vibration process, which requires a large number of construction personnel to cooperate. During the concrete pouring process, a large amount of construction vibration is required, and because the height of the mold is too high, the personnel need to set up a ladder during the construction process, and the ladder is easy to slip during use.
