Offshore wind power single pile-bucket composite foundation and construction method thereof

Abstract

The invention provides an offshore wind power single pile-bucket composite foundation, which comprises a single steel pipe pile and a bucket, wherein a connecting sleeve part which is through along an axial direction, is arranged in the middle position of the bucket, a lower end of the single steel pipe pile passes through the connecting sleeve part and is inserted into a seabed, the single steel pipe pile is in grouting connection with the connecting sleeve part, an anti-sinking ring sleeves the single steel pipe pile, the anti-sinking ring is positioned under the bucket and the bucket abuts against the anti-sinking ring. The invention also provides a construction method of the offshore wind power single pile-bucket composite foundation. The offshore wind power single pile-bucket composite foundation has the advantages of simple structure and novel design. The single steel pipe pile and the bucket are arranged and the single steel pipe pile passes through the bucket and is inserted into the seabed. The composite foundation can increase the horizontal rigidity of a mud line and can be applied to a special geology with a thicker silt layer.

Description

technical field [0001] The invention relates to an offshore wind power foundation, in particular to an offshore wind power single pile bucket 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 fo...

AI Technical Summary

Problems solved by technology

The above-mentioned foundation adds a hollow gravity foundation to the position of the steel pipe pile close to the seabed, which increases the stiffness of the single pile foundation near the seabed, but cannot further improve the bearing capacity of the single pile foundation
