Cylindrical offshore wind generating set foundation structure and construction method thereof
The invention relates to the technical field of hydraulic structures, in particular to a cylindrical offshore wind generating set foundation structure and a construction method thereof. The cylindrical offshore wind generating set foundation structure comprises cylindrical foundations, tension legs are arranged on the upper side of the cylindrical foundations, steel pipe piles are arranged on theupper sides of bearing floating bodies, and a bearing cross rod is arranged on the inner walls of the upper sides of the steel pipe piles. Supporting rods are arranged at the position, located on theupper side of the bearing cross rod, in the steel pipe piles, a main barrel is arranged in the middle of the bearing cross rod, and a draught fan tower barrel is arranged on the upper side of the mainbarrel. Negative pressure construction is utilized through the cylindrical foundations, the construction time is greatly shortened, various expenses are correspondingly reduced, transportation is convenient and fast, and construction is flexible. The cylindrical foundations have the characteristic of towing, and can be towed to a use place by a barge in a shallow water area by utilizing the air floatation towing capability of the cylindrical foundations to finish subsequent construction; meanwhile, the offshore abnormal climate interval construction can be better carried out; and the cylindrical foundations are jacked up from the soil due to reusability and reverse pressurization, and can be dragged to a new place again to be continuously used.
本发明涉及水工建筑物技术领域，尤其为一种筒形海上风力发电机组基础结构及其施工方法，包括筒型基础，所述筒型基础的上侧设置有张力腿，所述承载浮体的上侧设置有钢管桩，钢管桩的上侧内壁设置有承载横杆，所述钢管桩的内部位于承载横杆的上侧设置有撑杆，所述承载横杆的中间处设置有主筒体，所述主筒体的上侧设置有风机塔筒，通过筒型基础利用负压施工，施工时间大幅缩短，各项费用也相应降低，运输便捷、施工灵活，筒型基础具有可拖航的特性，在浅水区，也可利用其气浮拖航的能力，用驳船拖至使用地点，完成后续施工；同时也可以更好的在海上异常气候间隔施工；重复利用性，反向加压使筒型基础从土中被顶起，便可重新拖至新地点继续使用。
