Embodiment 1
[0027] As attached to the manual figure 1 As shown, the present invention is a new type of pile foundation for offshore wind engineering, including steel pipe 1, steel pipe 1 inner wall composite concrete lining pipe 2, steel bar 3 and reinforced concrete pile core formed by concrete pouring, and the steel pipe is coated with fluorine resin for anticorrosion Layer 4 to improve its corrosion resistance. And the steel bar 3 lower end in the pile core is from the sharp cone of the steel pipe 1 lower end such as figure 2 The shown oblique through hole 6 passes through and expands to reach the bedrock 12 of the seabed. Outside the pointed cone, concrete wraps the pierced steel bar 3 and passes through the concrete extruded through hole 7 on the pointed cone below the through hole for passing through the steel bar. It is integrated with the reinforced concrete pile core in the pipe, the concrete is filled under the steel pipe 1 and the concrete solidifies itself, forming a large h...
