Bucket anchor combined offshore wind turbine foundation structure and construction method
The invention provides a barrel anchor combined offshore wind turbine foundation structure and a construction method. The barrel anchor combined offshore wind turbine foundation structure comprises a negative pressure barrel, anchor rods, a steel frame and a steel platform. The negative pressure cylinder is a cylinder body with a downward opening, and when vacuum negative pressure is formed in the cylinder through suction, the cylinder wall is cut into the seabed; the bottom of the steel frame is arranged on the top surface of the negative pressure cylinder, and the top of the steel frame is connected with the steel platform; the bottoms of the anchor rods incline outwards and are anchored into the seabed, and the tops of the anchor rods are fixed to the periphery of the steel platform. And the steel platform is arranged at the top of the steel frame, is used for mounting a fan and is positioned above the sea water surface. The negative pressure cylinder mainly bears vertical load, and is light in self weight, low in cost, convenient to hoist and convenient to construct and install; the tension anchor rods are arranged on the periphery of the platform, anti-overturning tension is provided, and the effect of keeping the stability of the foundation and the platform is good; in the tensioning process of the anchor rod, the negative pressure cylinder can be pressed downwards, so that the inner wall of the negative pressure cylinder is attached to the seabed more tightly, the bearing capacity is higher, and the foundation stability is higher.
本申请提出了一种桶锚组合的海上风机基础结构及施工方法，包括：负压筒、锚杆、钢架、钢平台；所述负压筒为开口向下的筒体，在筒内抽吸形成真空负压时，筒壁切入海床；所述钢架，其底部设置于负压筒顶面，其顶部与所述钢平台连接；所述锚杆有若干个，其底部向外倾斜锚入海床，其顶部固定于钢平台周边；所述钢平台设置于所述钢架顶部，用于安装风机，位于海水面以上。本申请由负压筒主要承受竖向荷载，自重轻，成本低，便于吊装，施工安装方便；将受拉锚杆布置在平台周边，提供抗倾覆拉力，保持基础及平台稳定效果较好；锚杆在张拉过程中，可以下压负压筒，使负压筒内壁与海床贴合更紧密，承载能力更强，基础稳定性更高。
