As the berth of a small ship is not fully considered in the initial construction of part of deep water wharfs, the constructed wharfs need to meet the requirements of collecting, transporting and docking the small ship along with the improvement of the ratio of the rotation and the throughput in water, and the ratio of the large berth docking the small ship is higher. The large ships and the small ships arrive at the port and are loaded and unloaded on the deep water wharf, a large number of small-ton-level ships stop at the existing berths, on one hand, the utilization of the existing deep water berths is greatly wasted, on the other hand, the non-productive berthing time of the wharf is increased due to the fact that a large number of small ships approach and leave the port, the effective utilization rate of the berths of the wharf is reduced, and the large ships entering the port are influenced. Under the condition that the newly-built small wharf is immature, the rear edge of the wharf is improved, and the berth of the small ship is increased.

In the traditional transformation method, the pile foundation is generally added on the bank side of the wharf bent frame, and the node is newly poured on the upper part of the wharf bent frame to form a platform. However, the increase of pile foundations in projects along the Yangtze river leads to increase of choked flow, has influence on flood control, and has the advantages of complex approval procedures, multiple construction procedures, long construction period and higher project investment cost.

Therefore, it is a problem to be solved by those skilled in the art to provide a safe and reliable berthing structure with simple construction.
