Description

Technical Field

[0001] The invention belongs to the technical field of marine transportation of prefabricated bridge piers, and in particular relates to a pier body shipping jacking and fixing tool. Background Art

[0002] In the construction of cross-sea bridges, the prefabricated pier body adopts a standardized, modular, and factory-based operation mode. Compared with the traditional cast-in-place pier column construction method, it not only reduces construction costs and safety risks, but also improves project quality and shortens construction time. Therefore, the overall prefabrication method of the pier body is increasingly used in bridge construction. When the prefabricated pier body is transported by barge, in order to prevent overturning and relative movement, it is necessary to set a locking and limiting device between the pier body segment and the transport barge to fix the pier body and the hull as a whole to ensure transportation safety. In addition, the prefabricated concrete segment beam of the offshore pier is divided into three segments: upper, middle, and lower. The size of each segment is different, resulting in a set of transportation fastening tooling that cannot meet the transportation requirements of all segment pier bodies. Therefore, in order to save transportation costs and improve transportation efficiency, a pier body shipping top tightening and fixing tooling was invented by comprehensively considering the characteristics of the pier body and ship structure to meet the marine transportation requirements of pier bodies of different specifications.
