Negative pressure barrel with transition section and underwater single pile combined offshore wind turbine foundation and installation method
The invention relates to a negative pressure barrel and underwater single pile combined offshore wind turbine foundation with a transition section. The negative pressure barrel and underwater single pile combined offshore wind turbine foundation comprises an upper structure and a lower structure connected with the upper structure. The upper structure comprises a transition section, more than two inclined supporting pieces and a negative pressure barrel piece, one ends of the more than two inclined supporting pieces are respectively connected with the transition section, and the other ends of the more than two inclined supporting pieces are respectively connected with the negative pressure barrel piece; a transition section connecting part is arranged at the lower part of the transition section; the lower structure is an underwater single pile connected to the seabed, and the upper portion of the underwater single pile is provided with a single pile connecting part connected with the transition section connecting part. The connecting mode of underwater grouting between the pile barrels is abandoned, the connecting scheme that the inclined supports are combined with the grouting transition section above the seabed surface is adopted, loads can be transmitted more effectively, the connecting reliability is high, and construction is convenient; a vertical structure is adopted, structural design is optimized, connection strength is improved, and offshore construction procedures are reduced.
本发明涉及一种带过渡段的负压桶与水下单桩组合的海上风机基础，其包括：上部结构和与上部结构相连接的下部结构；所述上部结构包括过渡段、两个以上的斜支撑件和负压桶件，两个以上的所述斜支撑件的一端分别与过渡段相连接，两个以上的斜支撑件的另一端分别连接有负压桶件；所述过渡段的下部设有过渡段连接部；所述下部结构为连接于海底上的水下单桩，所述水下单桩的上部设有与过渡段连接部相连接的单桩连接部；本发明摒弃了桩桶之间水下注浆的连接方式，采用斜支撑结合海床面以上灌浆过渡段的连接方案，可以更有效的传递荷载，连接可靠性高且便于施工；采用上下结构，优化结构设计，提高连接强度，减少海上施工工序。
