Embodiment 1
[0036] A method for preparing an offshore wind generator base, the wind generator base includes a tower lower end and a seabed foundation.
[0037] The lower end of the tower tube is hollow in the shape of a truncated cone, including a tube wall, an inner rod and a crossbeam. for connecting the barrel wall and the inner rod.
[0038] The seabed foundation includes a support part affixed to the circular platform at the lower end of the tower and a conical column embedded in the seabed. There are 8 conical columns, the upper ends of which are all affixed to the support part, and the lower end Wedge into the seabed, the tapered column is a hollow structure, the upper section is cylindrical, the lower section is conical, and filler injection ports are arranged on the top side.
[0039] The material of the tapered column is high-strength stainless steel, and the high-strength stainless steel is calculated by mass percentage: C: 0.03%, Si: 0.6~1.0%, Mn: 1.5%, Cr: 6.2%, Ni: 2.3%, N...
