Pile sinking method for offshore wind power pile foundation
The invention belongs to the field of large steel cylinder vibration sinking construction devices, and relates to a pile sinking method for an offshore wind power pile foundation. Lifting the platform to adjust the position and elevation of the platform; lowering an anchor falling system; primarily driving a 1 # pile by a pile driving barge; the platform tightly holds the 1 # pile; 2 # piles are hoisted and hit by the pile driving barge; moving the platform, and holding the 1 # pile and the 2 # pile; 3 # and 4 # piles are hoisted and driven; and the platform and the compound pile foundation are moved away to the elevation. The pile sinking method is realized on the basis of a suspended positioning platform, and the problems of complex construction process, low construction efficiency, high cost investment, low precision, high risk and large potential safety hazard of a traditional bottom-supported positioning platform for positioning and a crane ship for hoisting a pile foundation are solved.
本发明属于大型钢圆筒振沉施工装置领域，涉及一种海上风电桩基的沉桩方法，包括船舶驻位；吊放平台调整平台位置、高程；下放锚坠系统；打桩船初打1#桩；平台抱紧1#桩；打桩船吊打2#桩；平台移位、抱紧1#、2#桩；吊打3#、4#桩；移走平台以及复打桩基至标高。该沉桩方法基于悬浮式定位平台实现，解决传统采用坐底式定位平台定位、起重船吊打桩基施工工艺复杂、施工效率低、成本投入大、精度低、风险高、安全隐患大的问题。
