Assembly type offshore wind power foundation anti-scouring energy dissipation structure and mounting method thereof
The invention discloses an assembly type offshore wind power foundation anti-scouring energy dissipation structure. The structure is provided with a center pile casing surrounding a single pile foundation and an annular spherical top plate buckled on the outer side of the center pile casing in a sleeve mode, wherein the sphere center of the annular spherical top plate is located below the structure, a protection pad is arranged on the inner side of the center pile casing, the annular spherical top plate is fixed on the upper end of the central pile casing, the lower ends of the annular spherical top plate and the central pile casing are connected through an annular bottom plate, a radial partition plate and a circumferential partition plate are arranged in an energy dissipation cavity formed by the annular spherical top plate, the central pile casing and the annular bottom plate, energy dissipation holes are formed in the circumferential partition plate, the radial partition plate andthe annular spherical top plate, energy dissipation blocks are fixed on the annular spherical top plate, the energy dissipation structure is formed by splicing at least two assembling units, each assembling unit is of a steel-concrete structure, the two sides of the assembling units are each provided with one radial partition plate, and the top spherical plate is connected to a lifting ring. The invention further discloses a mounting method of the above energy dissipation structure. The energy dissipation structure can effectively protect soil around an offshore wind power foundation, and is easy and convenient to mount and low in manufacturing cost.
本发明公开了一种装配式海上风电基础防冲刷消能结构，设有环绕在单桩基础周围的中心护筒以及扣套在中心护筒外侧的环形球面顶板，环形球面顶板的球心在结构下方，在中心护筒内侧设有护垫，环形球面顶板和中心护筒上端固定、下端通过环形底板连接，在由它们构成的消能腔室内设有径向隔板和周向隔板，在周向隔板、径向隔板和环形球面顶板上均设有消能孔，在环形球面顶板上固定有消能块；该消能结构是采用至少两瓣装配单元拼接而成的，装配单元采用钢混结构，两侧各设有一个径向隔板，顶部球面板上连接有吊环。本发明还公开了上述消能结构的安装方法。本发明的消能结构能够有效保护海上风电基础周围的土体，并且安装简便，造价低。
