Jacket foundation structure of offshore wind turbine and construction method of jacket foundation structure
The invention provides a jacket foundation structure of an offshore wind turbine and a construction method of the jacket foundation structure, and relates to the field of offshore wind power foundations. The jacket foundation structure of the offshore wind turbine comprises an upper buoyancy tank, a jacket, a lower buoyancy tank and a plurality of suction cylinders which are arranged from top to bottom, wherein the jacket is fixedly connected between the lower buoyancy tank and the upper buoyancy tank; the multiple suction barrels are installed on the lower portion of the lower buoyancy tank, and a suction pump is installed in the lower buoyancy tank. A lower transition structure is arranged between the lower buoyancy tank and the suction cylinder, the lower transition structure comprises a plurality of reinforcing rib plates with narrow upper parts and wide lower parts, the plurality of reinforcing rib plates are circumferentially arranged around the axis of the suction cylinder at intervals, and the outer contours of the plurality of reinforcing rib plates protrude to the outer side of the edge of the suction cylinder; a bottom supporting structure is further arranged on the lower side of the lower buoyancy tank, and the bottom supporting structure and the lower transition structure are distributed in a staggered mode. The overall buoyancy is improved through the double-buoyancy-box design, horizontal floating hauling can be implemented, the transportation convenience is better, the bottom supporting structure is additionally arranged and matched with the suction barrel, and the stability is better after the whole foundation is installed.
本发明提供了一种海上风机的导管架基础结构及其施工方法，涉及海上风电基础领域。海上风机的导管架基础结构包括自上而下设置的上浮箱、导管架、下浮箱和多个吸力筒，导管架固定连接在下浮箱和上浮箱之间；多个吸力筒分别安装在下浮箱的下部，下浮箱中安装有抽吸泵；下浮箱与吸力筒之间设有下过渡结构，下过渡结构包括多个上窄下宽的加强肋板，多个加强肋板绕吸力筒的轴线呈周向间隔布置，多个加强肋板的外轮廓凸出至吸力筒的边缘外侧；下浮箱的下侧还设有底部支撑结构，底部支撑结构与下过渡结构错开分布。利用双浮箱设计提高了整体浮力，可实施卧式漂浮拖运，运输的便捷性更好，增加底部支撑结构并配合吸力筒，整个基础安装后的稳定性更好。
