Embodiment Construction

[0041] In order to further understand the content, characteristics and effects of the present invention, the following embodiments are exemplified and described in detail with the accompanying drawings as follows:

[0042] like Figure 1 to Figure 3 As shown, the present invention provides an eccentric multi-tube jacket foundation and a construction method for the complete wind power machine. The eccentric multi-tube jacket foundation 2 can be self-floating and towed. Compared with traditional dry tow transportation, it does not require large transport ships, and at the same time saves large-scale hoisting equipment, ensures transportation and installation stability, and reduces transportation and installation costs.

[0043] like Figure 4 and Figure 5 As shown, the eccentric multi-cylinder jacket foundation 2 generally includes three to four suction cylinders 21, and the plurality of suction cylinders 21 are connected to the jacket 22 through the top reinforcement section...

Abstract

The invention belongs to the technical field of offshore wind power foundations, and discloses an eccentric multi-tube jacket foundation and a construction method for a complete wind power machine. The rest of the uprights are inclined from bottom to top in the direction of the vertical uprights, so that the center of gravity of the eccentric multi-tube jacket foundation is inclined to one side; It is assembled on both sides of the towing vessel; the tugboat is provided with a mounting frame, which is connected to the jacket hoop device and the tower righting device, and a winch is installed on the top of the mounting frame, and the winch is used to control the length of the hoisting cable. The eccentric multi-tube jacket foundation of the present invention has lower requirements on the construction vessel, and has stronger stability during construction; and the construction method of the wind power complete machine can ensure the levelness, sinking speed and stability, and reduce the construction cost. Simple to operate and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power foundation, and in particular relates to an eccentric multi-tube jacket foundation and a construction method for a complete wind power machine. Background technique [0002] With the development and utilization of offshore wind energy resources, the foundation design of megawatt-class offshore wind turbines has become a difficult problem. In order to withstand the wave impact at sea, strong wind loads, seawater corrosion, construction and transportation loads, etc., the foundation of offshore wind turbines is compared with onshore wind turbines. The structure is complex, the technical difficulty is high, and the construction cost is high. [0003] The current offshore wind power projects mostly adopt the split installation process, which mainly includes foundation construction, wind turbine tower hoisting, wind turbine hoisting, and whole machine commissioning. Split installations lim...
