Composite offshore wind power foundation and construction and installation method
The invention provides a composite type offshore wind power foundation and a construction and installation method. The composite type offshore wind power foundation comprises a single pile, a gravity type foundation, a suction type foundation and a floating body. A single pile is mounted on the upper surface of the gravity type foundation, a suction type foundation is mounted on the lower surface of the gravity type foundation, a plurality of floating bodies are mounted on the periphery of the gravity type foundation, the top of the single pile is used for mounting a fan unit, and the offshore wind power foundation is transported to a set position of a sea area and sinks by injecting water into the floating bodies. And after the suction pile foundation sinks to a designated position, the seawater in the suction pile foundation is pumped out for foundation penetration until the suction type foundation makes contact with a soil body, installation of the offshore wind power foundation is completed, the construction and manufacturing advantages of a single-pile foundation, the stability advantage of a gravity type foundation and the advantages that the suction type foundation does not need piling and rock socketed are fully utilized, and the construction period is shortened. And a series of problems of hole collapse risk, prolonged construction period, high construction cost, shortage of construction ship equipment resources and the like caused by pile type foundation rock-socketed construction can be effectively avoided.
本发明提供了一种复合型式的海上风电基础及施工安装方法，包括：单桩、重力式基础、吸力式基础和浮体；所述重力式基础上表面安装单桩，重力式基础下表面安装吸力式基础，所述重力式基础四周安装若干个浮体，单桩的顶部用于安装风机机组，将海上风电基础运输至海域的设定位置，通过向浮体注水使得海上风电基础下沉，下沉至指定位置后通过抽出吸力桩基础内海水进行基础沉贯，直至吸力式基础与土体接触，完成对海上风电基础的安装，充分利用单桩基础的施工和制造优势、重力式基础的稳定性优势以及吸力式基础无需打桩、嵌岩的优势，可有效避免桩式基础嵌岩施工引发的塌孔风险、施工工期延长、造价高和施工船机设备资源紧缺等一系列问题。
