Offshore wind power self-standing type polygonal cylinder type foundation
The invention relates to an offshore wind power self-standing type polygonal cylinder type foundation. The foundation comprises a transition section and a polygonal cylinder arranged at the lower endof the transition section; the upper end of the transition section is in butt joint with a tower cylinder; a polygonal bottom plate is arranged at the top of the polygonal cylinder; a bottom plate beam system is arranged on the polygonal bottom plate; and the lower end of the transition section is connected with the polygonal bottom plate through the bottom plate beam system. The defects that a steel cylinder wall of a traditional cylinder foundation is prone to buckling, formwork erecting cannot be realized due to the fact that the span of the bottom plate is too large, a jig frame needs to be arranged, and stability is poor during floating transportation are overcome; the foundation is suitable for ocean geological conditions with a thick soft clay layer and has the advantages of being large in bearing area, capable of negative-pressure sinking, capable of being installed in one step, good in-place stability and the like; the foundation further has the unique advantages that the cylinder wall cannot be bent, the span of the bottom plate is reduced, formwork erecting is convenient, the floating transportation gravity center of the foundation is low, the stability is good, the costof a jig frame is saved, formwork manufacturing is convenient, and the recycling rate is high; and the stability of foundation sinking construction is improved, and the comprehensive manufacturing cost can be reduced by 10%-25% compared with a conventional composite cylinder type foundation.
本发明涉及一种海上风电自立式多边形筒型基础，该基础包括过渡段和设置在过渡段下端的多边形筒，过渡段上端与塔筒对接，多边形筒顶部设有多边形底板，多边形底板上设有底板梁系；过渡段下端通过底板梁系与多边形底板连接。本发明解决传统筒型基础钢筒壁易屈曲、底板跨度过大无法支模、需要设置胎架、浮运时稳性不佳等弊端，适用于软弱黏土层较厚的海洋地质条件，不仅兼有承载面积大、可负压下沉、可一步式安装以及在位时稳定性佳等优点，且独有筒壁不会屈曲、减小底板跨度方便支模、基础浮运重心低、稳性佳、省去胎架费用、模板制作方便、重复利用率高等优势，提高了基础下沉施工的稳定性，相比于常规复合筒型基础可减少综合造价10％～25％。
