Embodiment

[0023] A levelable tripod-type offshore foundation structure for offshore wind turbine equipment, including a main body of the foundation, a leveling device and a dry tank grouting device, the main body of the foundation includes a steel pipe system tripod 1, and three piling guide pipes 2 With three pile pipes 3, the bottom of the tripod 1 is an equilateral triangle, and the three equal-length steel pipes are used to fix the central tube at the top of the tripod 1 from the three corners of the triangle. The top of the central tube is fixed with a tool connecting plate 4, three The piling guide pipe 2 is vertically fixed to the three corners at the bottom of the tripod 1, and the three steel core-filling pile pipes 3 are respectively guided by the three piling guide pipes 2 for piling operation; the leveling device is three closed cylinders with the same structure 5. The cylindrical body 5 is sealed and fixed with the pipe wall at the lower end of the piling guide pipe 2 throug...

Abstract

The invention discloses a tripod type leveling offshore foundation structure which comprises a foundation main body part, a leveling device and a dry type cabin grouting device, wherein the foundation main body part comprises a steel pipe type tripod and a pile body, the leveling device comprises three closed cylinder bodies, and the dry type cabin grouting device comprises three closed dry type cabins. A construction method comprises the steps of: positioning a tripod through a hoisting device and piling through a piling guide pipe, leveling through the leveling device, installing an offshore tool, measuring the levelness of a foundation structure for secondary leveling, connecting cabin covers of the dry type cabins in a sealing manner, injecting gas in the dry type cabins for discharging a water body and grouting, and solidifying a pile tube and the piling guide pipe into a whole. The invention has the advantages of capability of realizing leveling and grouting operations of a foundation structure system by adopting a leveling structure system and a dry type cabin grouting structure system, simpleness and rapidness in construction, less quantity of required construction devices, avoidance of an expensive underwater grouting construction device, low construction cost and low comprehensive cost.

Description

technical field [0001] The invention relates to an offshore foundation structure and a construction method thereof, in particular to an adjustable tripod type offshore foundation structure and a construction method thereof. Background technique [0002] At present, in offshore wind power projects, the foundation structure forms usually include: Mono-pile, Tripod, Jacket, Gravity based, Suction Bucket and Floating platform structure (Floating type), etc. These foundations usually require additional design and leveling means and methods. For foundations with piles, operations such as underwater grouting and connection are required at the pile head. These processes are very expensive for construction in sea areas. Contents of the invention [0003] In view of the above existing problems, the present invention provides a levelable tripod-type offshore foundation structure and construction method, the foundation structure and construction method can significantly reduce the co...
