Offshore wind power pile foundation of novel riprap collar protection structure

The invention discloses an offshore wind power pile foundation protection measure for reducing scouring, introduces a new collar design on the basis of riprap protection, and relates to the technical field of offshore pile foundations. The scour protection device comprises a riprap assembly and a collar assembly, and the riprap assembly surrounds the periphery of the pile within a certain range and partially exists in a groove of a collar. The shaft ring assembly is arranged on the outer side of the offshore wind power steel pipe pile and below the seabed surface based on the design of a balance scouring pit. According to the offshore wind power pile foundation, scouring within a certain range around the pile is reduced, horseshoe vortexes can be controlled to a certain degree, the offshore wind power steel pipe pile is protected, and the service life of the offshore wind power steel pipe pile is prolonged. 本发明公开了一种减少冲刷的海上风电桩基防护措施，在抛石防护的基础上引入了新的轴环设计，涉及海上桩基技术领域。该冲刷防护装置包括：抛石组件、轴环组件，所述抛石组件围绕在桩周一定范围内，并部分存在于轴环的凹槽之
