The invention discloses a fabricated offshore wind turbine floating foundation structure and a construction method thereof. The foundation structure comprises an upwind foundation arm assembly and a downwind foundation arm assembly. A guiding shear-resisting structure is arranged on the connecting face of the upwind-direction base arm assembly and the downwind-direction base arm assembly, and the upwind-direction base arm assembly and the downwind-direction base arm assembly can be installed in an aligned mode and resist shear force through the guiding shear-resisting structure. The upwind foundation arm assembly is respectively connected with the at least two downwind foundation arm assemblies through bolt components to form a Y-shaped floating foundation, and meanwhile, a waterproof sealing structure is arranged on the connecting surface of the upwind foundation arm assembly and the downwind foundation arm assemblies; according to the floating foundation structure, independent manufacturing of all the foundation arm assemblies is achieved, the requirement for a final assembly site is lowered, the construction difficulty is lowered, batched part manufacturing is achieved, and on-site splicing operation in shallow water and deep water sea areas is achieved.
本发明公开了一种装配式海上风机漂浮基础结构及其施工方法,基础结构包括上风向基础臂总成和下风向基础臂总成;所述上风向基础臂总成与下风向基础臂总成的连接面处设有导向抗剪结构,通过该导向抗剪结构使上风向基础臂总成与下风向基础臂总成能够对齐安装并抵抗剪切力,所述上风向基础臂总成通过螺栓组件分别与至少两个下风向基础臂总成形成连接,构成Y字形漂浮基础,同时所述上风向基础臂总成与下风向基础臂总成的连接面处设有防水密封结构;本发明的漂浮基础结构,实现对各基础臂总成的独立制作,降低了对总装场地的要求,降低了施工难度,实现了部件制造的批量化,实现浅水和深水海域的现场拼装作业。
