Embodiment Construction
[0015] Such as figure 1 As shown, the single-pile wind turbine foundation in this embodiment has a steel pipe type foundation pile 1 . Different from the traditional wind turbine foundation structure, in this example, 4 stabilizer wings 2 made of steel plate (model Q345C) are welded on the foundation pile 1 at the elevation near the surface below the seabed mud surface. The four stabilizing wings 2 are radially arranged around the foundation pile 1, the length direction is parallel to the foundation pile axis, the width direction is perpendicular to the foundation pile axis, and the angle between two adjacent stabilizing wings is 90°.
[0016] Such as figure 2 As shown, in order to ensure the connection strength between the stabilizing wing 2 and the foundation pile 1, a support member 6 is also welded between the two. The specific structure of the stabilizer wing is as follows: image 3 As shown, its shape is approximately rectangular. Considering the pile driving resista...
