Embodiment 1
[0037] Such as figure 1 As shown, this embodiment provides a single pile foundation for a fan in an offshore wind farm, including steel pipe piles 1 and cast-in-situ piles 2, a wind turbine tower 4 is installed on the top surface of the steel pipe pile 1, and the steel pipe pile 1 passes through the seabed surface. And stand vertically on the top surface of the underwater bedrock, the inner lower end of the steel pipe pile is provided with a concrete connecting section 3, and the concrete connecting section 3 is extended downward with a cast-in-place pile 2, the lower end of the cast-in-place pile 2 is embedded in the bedrock, and the upper end is connected to the The concrete connecting section 3 is fixedly connected into one body. The lower end surface of the concrete connecting section 3 is flush with the lower end surface of the steel pipe pile 1, and the lower end surface of the concrete connecting section 3 is in close contact with the top surface of the underwater bedro...
Embodiment 2
[0046] to combine image 3 As shown, based on Example 1, the cast-in-place pile 2 is composed of a support pile. The cast-in-place pile 2 is square, and the axis of the square cast-in-place pile 2 coincides with the axis of the concrete connecting section 3 . Construction method see embodiment 1.
Embodiment 3
[0048]combine Figure 4 As shown, based on Example 1, the cast-in-situ pile 2 is composed of a supporting pile. Construction method see embodiment 1.
