It includes a type-one caisson 1, a type-two caisson 2, a supporting prefabricated block 3, a riprap foundation 4, a high foundation section 5, a low foundation section 6, and a transition section boundary line 7; the type-one caisson is arranged in the high foundation section, and the type-two caisson is arranged in the low foundation section, which are used to form the main structure of the wharf, the adjacent surfaces of the type-one caisson and the type-two caisson are the transition section boundary line, the supporting prefabricated block is arranged at the bottom of the type-one caisson on the left side of the transition section boundary line, and the riprap foundation is laid under the supporting prefabricated block.

[0024] Among them, the first type caisson is mainly used as a part of the base support structure, which is connected to the high base section, riprap base, supporting prefabricated blocks and other parts; the second type caisson is another part of the base support structure, which is connected to the low base section and the transition section boundary line. The supporting prefabricated blocks provide support for the first type caisson, enhancing the stability and bearing capacity of the overall structure. The high base section and the low base section are located on both sides of the transition section boundary line, forming base structures of different heights; the transition section boundary line is used to divide the boundary between the high base section and the low base section.

It connects the high base section, the riprap base, the supporting prefabricated blocks and other parts, providing a stable foundation for the entire supporting system. The riprap base is located below the high base section, which is used to disperse the load of the dock platform and protect the base structure to prevent the base from being damaged by the external environment. The supporting prefabricated blocks connect the type I caisson and the riprap base, which enhances the stability and bearing capacity of the overall structure. The front toe 8 and the rear toe 9 of the caisson are arranged at the front and rear of the type I caisson to reduce the resistance between the caisson and the water flow, guide the water flow, and protect the caisson and the supporting structure from damage.
