A kind of anti-scour structure for offshore wind power foundation and construction method thereof

Abstract

The invention discloses an anti-scouring structure of an offshore wind power foundation and a construction method thereof. The trumpet-shaped foundation transition section is reduced from bottom to top. The top of the foundation transition section is fixed with a tower through a flange, and short piles pressed into the seabed are arranged around the cylindrical foundation, and each short pile points to the cylindrical foundation. The intersection of the line connecting the center of the circle and the circumference of the cylindrical foundation is fixed with a second cable buckle; the top side of the short pile is fixed with a first cable buckle, and a ring is laid between the second cable buckle and the first cable buckle. shaped coating; the inner ring of the coating is fixedly connected to the second cable buckle, and the outer ring of the coating is tightened by the first cable provided on the first cable buckle; the other end of the first cable is fixedly connected to the tower . The invention aims to provide a fast, efficient and economical erosion protection method for the cylindrical foundation, and improve the overall safety performance of the cylindrical foundation.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to an anti-scouring structure for an offshore wind power foundation and a construction method thereof. Background technique [0002] my country's offshore wind power development is on the rise, and many offshore wind farms have been built one after another. Offshore wind power has the advantages of low turbulence, does not occupy cultivated land, and is close to developed coastal areas, and its installed capacity is increasing year by year. However, the offshore environment is complex, and factors such as wind, waves, and currents will affect the safety and stability of offshore wind power structure operation. Therefore, effective protection measures are the key link to ensure the long-term operation of offshore wind power. [0003] There are various forms of foundation structures for offshore wind power, including gravity foundations, single pile foundations, multi-pi...

AI Technical Summary

Problems solved by technology

However, due to the large diameter of the cylindrical foundation structure compared with the single pile, multi-pile, jacket, etc., it is easy to cause erosion in the environment with large ocean currents.

For the wide submersible offshore wind power infrastructure, excessive scour will undoubtedly seriously affect the safety and stability of the infrastructure
