Problems solved by technology

[0003] With the large-scale development of ships, the conventional caisson gravity wharf structure is subject to more restrictions due to its own structural stress and structural stability.
The caisson gravity type wharf structure has high earth pressure, large section size, and large reinforcement, which lead to poor economic efficiency. It has no advantages in the comparison and selection of structural schemes. The conventional caisson gravity type structure is not suitable for large wharf structure selection.

Abstract

The invention discloses a caisson gravity type wharf structure. The caisson gravity type wharf structure comprises a caisson body, a breast wall and backfill. The breast wall is arranged at one end ofa top plate of the caisson body, and a bottom plate of the caisson body is arranged on a foundation bed. The interior of the caisson body and the position behind the caisson body are filled with thebackfill. The front wall of the caisson body is formed by connecting a plurality of U-shaped hook faces in an end-to-end manner. According to a combined structure, composed of a front wall and a partition plate, in the caisson gravity type wharf structure, the stress form is changed, the beneficial effects of large rigidity and high bending resisting capability are achieved, the foundation stressis effectively reduced, the caisson gravity type wharf structure is more applicable to hard soil, a dense sand layer and other foundations, the stress is reduced by 10% or above, and uneven settlementof the foundation is reduced. The caisson gravity type wharf structure has the beneficial effects that the structure is light, construction is simple, project materials are reduced, the project is economical, and the appearance is attractive; and the caisson gravity type wharf structure adapts to the large wharf project and particularly adapts to open sea large wharfs.

Description

technical field [0001] The invention relates to the technical field of wharf structures, in particular to a caisson gravity type wharf structure. Background technique [0002] A gravity wharf using a reinforced concrete caisson as the main structure is called a caisson gravity wharf. The caisson gravity wharf generally adopts the overall prefabrication method. The advantages of the prefabricated caisson wharf are that the structure is simple, the water can be installed at one time, the construction speed is fast, and it is widely used in various wharfs in China. [0003] With the development of large-scale ships, conventional caisson gravity wharf structures are subject to many limitations due to their own structural stress and structural stability. The caisson gravity type wharf structure has high earth pressure, large section size and large reinforcement, which lead to its poor economy. It has no advantages in the comparison and selection of structural schemes. The conve...
