Offshore wind power single pile foundation installation method
The invention discloses an offshore wind power single pile foundation installation method which comprises the steps that S1, a wind generating set, a tower drum and a pile foundation in a retired wind power foundation are dismantled, and a jacket foundation in the wind power foundation is left in seawater; s2, the upper end face of the jacket foundation is cut according to the size of the replaced pile foundation, so that a construction hole penetrating through the upper end face of the jacket foundation is cut; s3, the replaced pile foundation is inserted into seawater through the construction hole, and the lower end of the replaced pile foundation is inserted into the sea level; s4, grouting is conducted on the lower end portion of the replaced pile foundation; and S5, the replaced pile foundation is welded to the inner circumferential face of the construction hole. The offshore wind power single pile foundation installation method has the advantages of being simple, low in cost and the like.
本发明公开了一种海上风电单桩基础安装方法，所述海上风电单桩基础安装方法包括S1：拆除退役后的风电基础中的风力发电机组、塔筒和桩基础，且风电基础中的导管架基础留在海水内；S2：根据替换的桩基础的尺寸对导管架基础的上端面切割，以便切割出贯穿导管架基础的上端面的施工孔；S3：将替换的桩基础通过施工孔插入海水内且替换的桩基础下端部插入海平面内；S4：对替换的桩基础的下端部进行注浆；S5：将替换的桩基础和施工孔的内周面焊接。本发明的海上风电单桩基础安装方法具有方法简单、成本低廉等优点。
