Offshore wind power anchoring type pile foundation structure and construction method
The invention discloses an offshore wind power anchoring type pile foundation structure and a construction method, and belongs to the technical field of offshore pile foundations. The offshore wind power anchoring type pile foundation structure comprises a steel pipe pile, an anchor plate bottom plate, an anchor plate vertical plate, a tower drum, universal wheels, an inhaul cable and a radial spring; the multiple anchor plate vertical plates are distributed around the circumference of the steel pipe pile and fixedly connected with the anchor plate bottom plate, the tower barrel is coaxially arranged over the steel pipe pile, the multiple universal wheels are installed between the tower barrel and the steel pipe pile, the multiple inhaul cables are distributed around the circumference of the steel pipe pile, the top ends of the inhaul cables are connected with the tower barrel, the bottom ends of the inhaul cables are connected with the anchor plate vertical plates, and the multiple radial springs are distributed around the circumference of the steel pipe pile. One end of the radial spring is connected with the tower, and the other end is connected with the steel pipe pile. The horizontal shearing force and the additional bending moment of the fan unit are transmitted to the pile body on the mud surface through tensioning stress transmission of the inhaul cable, the horizontal load bearing capacity of the pile body can be improved, and then the steel cost of the pile foundation is reduced.
本发明公开了海上桩基础技术领域的一种海上风电锚拉式桩基结构及施工方法，包括钢管桩、锚板底板、锚板立板、塔筒、万向轮、拉索和径向弹簧，锚板底板固定套设在钢管柱泥上段的底端，多个锚板立板绕钢管桩圆周分布并与锚板底板固定连接，塔筒同轴设置在钢管桩正上方，多个万向轮安装在塔筒和钢管桩之间，多个拉索绕钢管桩圆周分布，拉索的顶端与塔筒连接、底端与锚板立板连接，多个径向弹簧绕钢管桩圆周分布，径向弹簧的一端与塔筒连接、另一端与钢管桩连接。本发明通过拉索张紧受力传递，将风机机组的水平剪力及附加弯矩传递到泥面处桩身，可以提高桩身的水平荷载承受能力，进而降低桩基础的用钢成本。
