Prefabricated combined structure steel pipe pile wind power generation platform

Abstract

The invention discloses a prefabricated combined structure steel pipe pile wind power generation platform. The prefabricated combined structure steel pipe pile wind power generation platform comprises a steel pipe connection section, a platform, prefabricated piles and a foundation steel pile, wherein the steel pipe connection section is vertical to the platform; the lower surface of the platform is supported by the plurality of prefabricated piles which are arranged in parallel; the bottoms of the prefabricated piles are connected with the foundation steel pile; the connection parts of the platform and the prefabricated piles are subjected to grouting treatment; the elevations of the connection parts are located above the water level of the highest tide so that the connection strength is guaranteed. Grooves are formed in the connection positions of the lower surface of the platform and the prefabricated piles; and the tops of the prefabricated piles are clamped into the grooves; the bottoms of the prefabricated piles and the foundation steel pile are connected by bayonet structures; the foundation steel pile is knocked into a seabed force keeping layer by a piling machine; the elevation of the top end of the foundation steel pile exceeds the elevation of the top of a seabed. The corrosion problem caused by seawater is effectively solved.

Description

technical field [0001] The invention relates to an offshore wind power generation infrastructure, in particular to a prefabricated steel pipe pile wind power generation platform. Background technique [0002] Wind power is the fastest growing new energy source in the world. So far, my country has built a large number of onshore wind farms in Inner Mongolia, Xinjiang, Gansu, Northeast China and the eastern coastal areas. However, with the rapid development of the wind power industry, onshore wind resources have been exhausted, and offshore wind power is imperative. Moreover, my country has a long coastline and abundant offshore wind energy resources, and offshore wind power will be greatly developed. According to the data released by the National Energy Administration, 44 offshore wind power projects will be put into operation in the next two years, which shows that the offshore wind power market has a very bright prospect in the next few years. [0003] Generally, wind powe...

AI Technical Summary

Problems solved by technology

[0004] The pile foundation structure of the existing offshore wind power generation platform is basically steel piles. The corrosion phenomenon of steel in seawater has always been an important factor affecting the service life of the platform, and the platform requires a lot of on-site pouring operations, which requires a large amount of on-site work and inconvenient operation. low efficiency
