Embodiment Construction

[0013] refer to figure 1 , figure 2 , a four-pile foundation on the water for offshore wind turbines, including four pipe piles 1 and a support platform, the upper center of the support platform is provided with a connecting pipe pile 2 for connecting the wind tower, and the lower part is provided with the four pipe piles. The intubation head 3 corresponding to the pile 1, in this embodiment, the support platform is square, and four pipe piles 1 are located at the four corners of the support platform.

[0014] The support platform is composed of multi-layer horizontal plates 4 and longitudinal support plates 5 welded between the multi-layer horizontal plates 4, and a reinforcing rib 6 is welded between the longitudinal support plates 5 and the horizontal plates 4 , simple structure and strong stability.

[0015] During construction, first drive the four pipe piles into the seabed, then insert the pipe head 3 on the support platform into the upper ends of the four pipe piles...

Abstract

The invention discloses an offshore wind power generator set waterborne four-pile foundation, which comprises four pipe piles and a support platform, wherein the center of the upper part of the support platform is provided with a connecting pipe pile, the lower part of the support platform is provided with pipe inserting heads corresponding to the four pipe piles, after the assembly, the pipe inserting heads are inserted into the upper ends of the pile pipes, in addition, concrete is poured in the pipe piles, the manufacturing of the pipe piles, the support platform and the like is completed in factories, only simple works such as piling and welding are needed in the construction site, the underwater operation is converted into the waterborne operation, the offshore construction period is reduced, the pipe inserting heads and the pipe piles adopt insertion connection modes, the leveling is easy, the construction difficulty is reduced, the structure is light and ingenious, the cost is low, the transportation is convenient, the transportation cost is reduced, and the dismounting is convenient after the service life period.

Description

technical field [0001] The invention relates to offshore wind power equipment, in particular to a basic platform for offshore wind power. Background technique [0002] With the rapid development of domestic offshore wind power generation, especially high-power wind turbines and deep-water offshore wind farms, the geological conditions in different sea areas vary greatly, and the foundation of offshore wind turbines must be able to adapt to a variety of complex geology. Therefore, for complex marine geological conditions , it is especially important to fix large wind turbines and their supporting structures on the seabed. [0003] Due to the high cost and long construction period of the high-pile cap foundation used in existing domestic offshore wind power projects, offshore operators spend a long time at sea, posing safety hazards and correspondingly increasing the investment cost of wind farms. Contents of the invention [0004] In order to overcome the deficiencies of t...
