Offshore wind power foundation anti-scouring structure and construction method thereof

Abstract

The invention discloses an offshore wind power foundation anti-scouring structure and a construction method thereof. The offshore wind power foundation anti-scouring structure comprises a cylindricalfoundation arranged on a seabed and aligned to the seabed level, and a horn-shaped foundation transition section with the cross section decreasing from bottom to top is arranged on the top surface ofthe cylindrical foundation, a tower tube is fixedly arranged at the top of the foundation transition section through a flange plate, short piles pressed into the seabed are arranged at the periphery of the cylindrical foundation in the circumferential direction, second buckles are fixedly arranged at the intersections of connecting lines of each short pile pointing to the center of the cylindricalfoundation and the periphery of the cylindrical foundation, first buckles are fixedly arranged on the top sides of the short piles, annular covering films are laid between the second buckles and thefirst buckles, inner rings of the covering films are fixedly connected with the second buckles, and outer rings of the covering films are tightened by first cables arranged on the first buckles; the other ends of the first cables are fixedly connected to the tower tube. The invention aims to provide a fast, efficient and economical erosion protection method for the cylindrical foundation, and theoverall safety performance of the cylindrical foundation is improved.

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
