Novel rock-socketed-preventing jacket pile foundation suitable for large megawatt fan
The invention relates to the technical field of offshore wind power, and discloses a novel rock-socketed-preventing jacket pile foundation suitable for a large megawatt fan, the novel rock-socketed-preventing jacket pile foundation comprises a pile foundation and a transition structure, and the transition structure comprises a main leg, an insertion leg and a connecting assembly; the connecting assembly comprises a backstop upper ring plate and a backstop lower ring plate; upper web plates are connected between the backstop upper ring plate and the main leg, cover plates are arranged on the upper web plates, a panel is connected between every two adjacent upper web plates, and an upper inner ring plate is arranged in the main leg; a backstop web plate is connected between the backstop upper ring plate and the backstop lower ring plate; and an inner toggle plate is connected between the inner wall of the insertion leg and the stop upper ring plate. The upper inner ring plate, the panel, the upper web and the cover plate form a stressed whole, so that the deformation and stress concentration of the main leg position can be reduced; the stop web and the inner toggle plate form a whole, so that deformation of the insertion leg in the radial direction can be reduced, the stress extreme value is further reduced, and accumulated fatigue damage is reduced; the backstop lower ring plate and the pile foundation are in backstop limiting, and sinking of the upper main body structure in the construction process is limited.
本发明涉及海上风电技术领域，公开了一种适用于大兆瓦风机的新型避免嵌岩导管架桩基础，包括桩基础和过渡结构，过渡结构包括主腿、插入腿和连接组件；连接组件包括止挡上环板、止挡下环板；止挡上环板与主腿之间连接有上腹板，上腹板上布置有盖板，相邻的两个上腹板之间连接有面板，主腿内设置有上内环板；止挡上环板与止挡下环板之间连接有止挡腹板；插入腿的内壁与止挡上环板之间连接有内肘板。上内环板、面板、上腹板、盖板形成一个受力整体，可减小主腿位置的变形和应力集中；止挡腹板、内肘板形成整体，可减小插入腿在径向上的变形，进而缩减应力极值，减小累积疲劳损伤；止挡下环板与桩基础止挡限位，限制上部主体结构在施工过程中下沉。
