Abstract

The invention discloses an offshore wind power single-pile foundation mechanism and a construction method thereof. The offshore wind power single-pile foundation mechanism and the construction methodthereof solve the technical problems that the construction period is long, the offshore operation difficulty is high, and the cost is high due to the fact that an existing offshore wind power ultra-large-diameter single-pile foundation is mainly constructed in an on-site pouring construction mode. The offshore wind power single-pile foundation mechanism comprises a middle column and N fan-shaped prisms, N first bolts and N second bolts, wherein N is larger than or equal to 2; at least one first stirrup is arranged in the circumferential region of the middle column; at least one second stirrupis arranged in an inner ring of the fan-shaped prisms; the first bolts perpendicularly penetrate through clamping rings of the first stirrups and clamping rings of the second stirrups, so that the middle column is fixedly connected to the fan-shaped annular prisms; at least one third stirrup is arranged on the two side surfaces of each fan-shaped prism; and the second bolts perpendicularly penetrate through clamping rings of the third stirrups so that every two fan-shaped prisms are fixedly connected.

Description

technical field [0001] The invention relates to the field of engineering transportation, in particular to an offshore wind power monopile foundation mechanism and a construction method thereof. Background technique [0002] Nowadays, offshore wind power energy development projects are constantly expanding in scale, and offshore wind power, as a clean energy source, has been welcomed all over the world. At present, my country's offshore wind power development is also rapidly spreading and getting better. There are currently 6 approved offshore wind power projects with a total of 1582MW; 8 projects have been started with a total of 1920MW. Offshore wind power is a highly technically complex field, and the complexity of the offshore wind power environment further increases its technical difficulty. In terms of its environment, the environmental impact factors of offshore wind power mainly refer to meteorological and hydrological conditions such as wind, waves, and currents. ...
