In the field of wharf engineering, an assembled structure is still in a starting stage, and most wharfs still use the traditional design and construction method of a cast-in-place crossbeam. The reason restricting the development of the fabricated wharf is that the steel bars are interfered when the prefabricated longitudinal and transverse beam is erected, and the error in the erecting and placing process is not easy to control. In an assembly type wharf structure, in order to ensure the continuity of stress, a certain extending length is reserved at a node of a prefabricated longitudinal beam of the wharf, so that binding or welding is performed; and a certain extending length also needs to be reserved for the prefabricated beam.
