Offshore wind power single pile foundation structure and construction method thereof
The invention relates to the technical field of offshore wind power, in particular to an offshore wind power single-pile foundation structure and a construction method of the offshore wind power single-pile foundation structure. The offshore wind power single-pile foundation structure comprises a pile foundation, a driving rod and a driven rod, the pile foundation is a hollow steel pipe pile, a grout outlet is formed in the side wall of the pile foundation, a sealing door used for sealing the grout outlet is hinged to the side wall of the pile foundation, the driving rod and the driven rod are both hollow steel pipes, one end of the driving rod is closed, and the other end of the driven rod is closed. The driving rod is coaxially arranged in the pile foundation, one end of the driven rod is communicated with and hinged to the driving rod, the other end of the driven rod is hinged to the sealing door, an opening is formed in the side wall, close to the sealing door, of the driven rod, and the diameter of the driven rod is smaller than that of the grout outlet. According to the offshore wind power single-pile foundation structure, the soil layer outside the pile foundation can be reinforced, the bearing condition of a soft soil layer is improved, the bearing capacity of a soil body is enhanced, and long-term safe operation of an offshore wind power unit is guaranteed.
本发明涉及海上风电技术领域，尤其涉及一种海上风电单桩基础结构和该海上风电单桩基础结构的施工方法。该海上风电单桩基础结构包括桩基础、主动杆和从动杆，桩基础为空心钢管桩，桩基础的侧壁上开设有出浆口，且桩基础的侧壁上铰接有用于封堵出浆口的封门，主动杆和从动杆均为空心钢管，且主动杆的一端封闭，主动杆同轴设置在桩基础内，从动杆的一端与主动杆连通并铰接，从动杆的另一端与封门铰接，从动杆在靠近封门位置的侧壁上开设有开口，从动杆的直径小于出浆口的直径。该海上风电单桩基础结构能够对桩基础外部的土层进行加固，改善了软弱土层的承载情况，加强了土体的承载力，有利于保证海上风电机组长期的安全运行。
