Technical Field

[0001] The utility model relates to the technical field of water transport engineering, in particular to a prestressed pipe pile bottom sealing device for water transport engineering. Background Art

[0002] The pile core of the prestressed pipe pile is sealed to prevent groundwater and surface water from soaking the bearing layer at the pile end through the pile core hole, thereby avoiding a reduction in the bearing capacity of the pipe pile. The existing patent (Announcement No.: CN220099912U) discloses a pipe pile bottom sealing concrete pouring device. The utility model provides a buffer chute to buffer the concrete poured into the prestressed pipe pile and guide the flow direction of the concrete to avoid frequent collisions between the concrete and the inner wall of the pipe pile to cause segregation, thereby ensuring that the bearing capacity of the pipe pile is not affected and improving its corrosion resistance. However, in actual applications, since the length of the buffer conduit is fixed, it can only be applied to pipe piles of a certain length. The lengths of the pipe piles used for different projects are different, which makes it difficult for the buffer conduit in the above technical solution to adapt to different pipe piles, and the actual use is limited. To this end, we propose a prestressed pipe pile bottom sealing device for water transport projects. Utility Model Content
