Offshore wind turbine double-shell single-pile foundation and mounting method thereof
The invention discloses anoffshore wind turbine double-shell single-pile foundation and a mounting method thereof. The foundation comprises an outer shell, an inner shell, annular ribs, longitudinal ribs, a pile top flange and blade type longitudinal ribs. The inner shell is arranged in the outer shell, a preset gap is kept between the inner shell and the outer shell to form a pile body, a pile cap used for containing a pile hammer is preset at the top end of the inner shell, the pile top flange is arranged at the top of the pile body, and the multiple annular ribs and the multiple longitudinal ribs are sequentially arranged in the gap at intervals from top to bottom. A plurality of watertight cabins used for being filled with concrete or seawater are formed, and the blade type longitudinal ribs are arranged at the bottom end of the pile body. The limitation of the ratio of the diameter to the wall thickness of a circular hollow section is broken through, and for a super-large-diameter single pile, a plate with smaller thickness can be used, so that the weight of the single pile is effectively reduced, and the economical efficiency is improved; and the friendliness of a manufacturing process and an offshore construction process is considered, so that the dependence on construction resources is reduced, and batch implementation is facilitated.
本发明公开了一种海上风机双壳单桩基础及其安装方法，该基础包括外壳体、内壳体、环肋、纵肋、桩顶法兰和刀片式纵肋；所述内壳体设置在外壳体的内部，且所述内壳体与外壳体之间保持预设的间隙，构成桩体，所述内壳体的顶端预设有用于放置打桩锤的桩帽，所述桩顶法兰设置在桩体的顶部，所述环肋和纵肋有多个从上至下依次间隔设置在间隙中，形成多个用于填充混凝土或海水的水密舱室，所述刀片式纵肋设置在桩体的底端；本发明突破了圆形中空截面的直径壁厚的比值的限制，对于超大直径的单桩，能够使用厚度更小的板材，有效降低了单桩的重量，提高经济性；考虑了制作工艺和海上施工工艺的友好性，减少了对施工资源的依赖，有利于批量化实施。
