Scouring protection construction method for offshore wind power pile foundation
The invention discloses an offshore wind power pile foundation scouring protection construction method which comprises the following steps: after piling of a pile foundation is completed, two laying boats are driven to two sides of the pile foundation in parallel; laying a plurality of interlocking row units around the pile foundation on two row laying ships according to a preset shape, and splicing to form two interlocking rows; the two geotextile laying ships are close to each other, and the two interlocking rows are connected through the connection reinforcing row to form an integral interlocking row; and the two row laying ships slowly translate outwards at the same time, and the integral interlocking row sinks along the pile foundation and is flatly laid outwards underwater. According to the scour protection construction method for the offshore wind power pile foundation, rapid construction can be conducted after piling, and scour pits formed after piling can be reduced to the minimum extent; the soft mattress can adapt to the change of a seabed and can prevent the bottom from being emptied; the integral interlocking row can enter water integrally without using large hoisting tools and the like, so that the construction is quick and simple, and the cost is low.
本发明公开了一种海上风电桩基础冲刷防护施工方法，包括步骤：桩基础打桩完成后，两条铺排船平行开至桩基础两侧；在两条铺排船上根据预设形状将若干个联锁排单元围绕桩基础进行铺设、拼接形成两个联锁排；两条铺排船相互靠近，将两个联锁排通过连接加强排连接，形成整体式联锁排；两条铺排船同时向外缓慢平移，将整体式联锁排沿桩基础下沉，并在水下往外平铺开。上述海上风电桩基础冲刷防护施工方法，可以在打桩后快速施工，可最小限度降低打桩后冲刷坑的形成；软体排可适应海床的变化，可防止底部被掏空的现象发生；整体式联锁排可整体入水，无需使用大型吊装工具等，施工快速简单，成本低。
