Pile foundation with anti-impact structure for offshore wind power and construction method thereof

A construction method of a pile foundation with an anti-impact structure for offshore wind power, the construction method comprising the following steps:

• step S100:
• designing a size of support shaft mechanisms, elastic absorbers, first sliding mechanisms and second sliding mechanisms of the anti-impact structure according to measurement information before construction, and completing prefabrication of the support shaft mechanisms, the elastic absorbers, the first sliding mechanisms and the second sliding mechanisms in a factory;
• step S200:
• after the prefabrication is completed, assembling the support shaft mechanisms, the elastic absorbers, the first sliding mechanisms and the second sliding mechanisms that are prefabricated in the factory, so as to form impact absorption rollers;
• step S300:
• assembling first hoop components, second hoop components and a plurality of the impact absorption rollers into anti-impact structure modules;
• and
• step S400:
• installing at least two fabricated anti-impact structure modules to the pile foundation, and performing end-to-end connection by bolts to form the anti-impact structure.
