Offshore wind power prestress UHPC large-diameter thin-wall single pile foundation
The invention discloses an offshore wind power prestress UHPC large-diameter thin-wall single pile foundation, and belongs to the technical field of wind power generation equipment. The single-pile foundation structure comprises a bottom steel pile shoe, a middle prefabricated UHPC pipe pile and a top flange plate. The steel pile shoe is connected with the prefabricated UHPC pipe pile through a prestressed steel strand, and the prefabricated UHPC pipe pile is connected with the flange plate through a prestressed anchor bolt. The prestressed UHPC pipe pile has the beneficial effects that the prestressed UHPC pipe pile is high in rigidity and bearing capacity, has excellent fatigue resistance, impact resistance and corrosion resistance and has remarkable advantages in the aspect of carbon emission. The problem of serious corrosion of current common steel piles and the problem of 1P resonance existing in deep water can be reduced, the later operation and maintenance cost of the structure is reduced, construction and installation are convenient, and high economic benefits and social benefits are achieved.
本申请公开了一种海上风电预应力UHPC大直径薄壁单桩基础，属于风力发电设备技术领域。该单桩基础结构包括底部钢桩靴，中部预制UHPC管桩及顶部法兰盘。所述钢桩靴与所述预制UHPC管桩通过预应力钢绞线连接，所述预制UHPC管桩与所述法兰盘通过预应力锚栓连接。本申请有益效果如下：预应力UHPC管桩刚度较大、承载力较高，同时具有优异的抗疲劳、抗冲击及防腐蚀性能，且在碳排放方面具有显著优势。本申请可减少目前常用钢桩的严重腐蚀问题及深水中存在的1P共振问题，降低结构后期运营维护成本，且便于施工与安装，具有较高的经济效益和社会效益。
