Connecting device of offshore wind power foundation, offshore wind power foundation and recycling method of offshore wind power foundation
The invention provides a connecting device of an offshore wind power foundation, the offshore wind power foundation and a recycling method of the offshore wind power foundation. The recycling method comprises the steps that equipment on an original single-pile foundation is dismantled, underwater cutting is conducted on the original single-pile foundation at the position 1-2 m below the mud surface, and an old single-pile foundation buried in soil is recycled; and the diad formed by the stand column and the connecting device is sequentially immersed in water and in soil, the top of the old single pile foundation is inserted into a cavity of the inner sleeve, and after the diad is immersed in place, grouting is conducted on the cavity, so that a gap between the inner sleeve and the old single pile foundation is filled with slurry. According to the method, the original single-pile foundation can be reutilized, the foundation in the soil is prevented from being dismantled, and the cost caused by dismantling and replacing all offshore wind power foundations can be reduced. In addition, the original old single pile foundation can increase the soil body strength at the position, and the bearing capacity of a new offshore wind power foundation can be improved.
本发明提出一种海上风电基础的连接装置、海上风电基础及其回用方法，其中回用方法包括：将原有单桩基础上的设备拆除，在泥面1‑2米以下的深度对原有单桩基础进行水下切割，埋在土中的旧单桩基础回用；将立柱与连接装置形成的二联体依次进行水下沉放和土中沉放，旧单桩基础的顶部插入内套筒的腔室内，二联体下沉到位后对腔室内进行注浆，使浆料填充于内套筒与旧单桩基础之间的间隙。本发明可将原有的单桩基础进行二次利用，避免土中基础的拆除，可降低由于拆除和更换全部海上风电基础所带来的成本。而且原有的旧单桩基础可增加该机位处的土体强度，有利于提高新的海上风电基础的承载力。
