Offshore photovoltaic pile foundation structure and pile sinking method thereof
The offshore photovoltaic pile foundation structure comprises a plurality of herringbone wing plate structures which are distributed in the circumferential direction of a pile foundation and fixed to the surface of the pile foundation, each wing plate structure comprises a main plate and a supporting plate, the main plates are fixed to the surface of the pile foundation and incline towards one side, and the supporting plates are fixed between the surface of the pile foundation and the main plates. The inclination direction of the supporting plate is opposite to that of the main plate, a first wedge-shaped part is arranged at the end, away from the surface of the pile foundation, of the main plate, a second wedge-shaped part is arranged at the bottom end of the main plate, a third wedge-shaped part is arranged at the bottom end of the supporting plate, and the wing plate structure serves as extension of the thickness and the diameter of the pile foundation. The contact area with a seabed soil layer is increased, the pile side friction resistance is increased, the vertical bearing capacity is improved, and the first wedge-shaped part, the second wedge-shaped part and the third wedge-shaped part are prone to penetrating into seabed soil; the hydraulic clamp is matched with the vibratory hammer, hard seabed soil is forced to be liquefied, the cutting part can conveniently penetrate downwards, and pile sinking is completed.
本发明提供了海上光伏桩基结构及其沉桩方法，包括沿着桩基的周向分布且固定在桩基表面的人字形的若干翼板结构，翼板结构包括主板和支撑板，主板固定于桩基表面且向一侧倾斜，支撑板固定于桩基表面和主板之间，支撑板的倾斜方向与主板相反，主板远离桩基表面的一端设有第一楔形部，主板的底端设有第二楔形部，支撑板的底端设有第三楔形部，翼板结构作为桩基厚度和直径的延展，用钢量少，造价低，显著加强桩基的抗弯、抗压能力，增大与海底土层的接触面积，增大桩侧摩阻力，提高竖向承载能力，第一楔形部、第二楔形部、第三楔形部容易刺入海床土内；采用液压夹具和振动锤配合，迫使坚硬的海床土液化，方便切割部向下刺入，完成沉桩。
