Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing and processing of conductor frame foundations, and in particular to a tower support tooling used for closing an offshore wind power conductor frame foundation. Background Art

[0002] The jacket is a spatial truss structure, the upper part of which is used to support wind turbines, and the lower part is connected to small steel pipe piles. The jacket structure is fixed to the seabed through 3-4 small steel pipe piles. The connection between the jacket and the small steel pipe piles is achieved by grouting. This type of jacket foundation is mostly used for wind turbine foundations or booster station foundations in deep water areas.

[0003] The fabrication and closure of the jacket is usually done in a straight or lying manner, depending on the fabrication capacity and shipping method of the construction plant. The truss structure in the closure process usually uses various supports or bases to fix the sheet structure or the main branch pipes, etc. After the structure is fixed, the closure welding is performed. If the tooling uses one or two steel pipes for temporary support, it will cause the jacket structure to shrink and deform greatly after welding, resulting in failure of the dimensional inspection. If the support tooling is too simple, it will cause the jacket to overturn or move in sections when the jacket is closed, causing damage to the jacket structure or injuries to personnel, which will pose a major safety problem.
