Abstract

The invention provides an offshore wind power multi-pile bearing platform composite foundation. The offshore wind power multi-pile bearing platform composite foundation comprises a bucket foundation and multiple steel pipe piles. The bucket foundation comprises an upper-layer bucket body with an opening in the upper portion and a lower-layer bucket body with an opening in the lower portion. The upper-layer bucket body and the lower-layer bucket body are separated by a separation plate. Multiple connecting sleeve parts are arranged on the separation plate. Each steel pipe pile sequentially penetrates the corresponding connecting sleeve part and the separation plate to be inserted into a seabed. The steel pipe piles and the connecting sleeve parts are in grouting connection. Concrete is poured into the upper-layer bucket body. A tower tube connecting segment is further arranged in the upper-layer bucket body. The invention further provides a construction method based on the offshore wind power multi-pile bearing platform composite foundation. The offshore wind power multi-pile bearing platform composite foundation is simple in structure and novel in design and is provided with the upper-layer bucket body with the opening in the upper portion and the lower-layer bucket body with the opening in the lower portion. The concrete is arranged in the upper-layer bucket body to serve as a bearing platform, the lower-layer bucket body is sunk below the seabed, corners on the foundation soil face are reduced, and the horizontal bearing performance of the foundation is further improved.

Description

technical field [0001] The invention relates to an offshore wind power foundation, in particular to an offshore wind power multi-pile cap composite foundation and a construction method. Background technique [0002] Nowadays, the global energy crisis is getting more and more serious, especially coal and oil, which are the main energy sources, not only have limited and non-renewable resources, but also cause serious pollution to the environment. In recent years, the greenhouse effect and global warming have become global environmental crises. Therefore, clean and green energy must become a future trend, and wind energy is one of them. my country has a vast territory, long coastline, and abundant offshore wind energy resources. Offshore wind farms have the advantages of high wind speed, long effective power generation time, do not occupy land, and are close to the load center, etc., and have good prospects for development. [0003] The structural types of wind turbine founda...
