Example Embodiment

[0060] Below in conjunction with accompanying drawing, the present invention will be further described, and the maximum diameter of the tower tube of this embodiment reaches 12m, and the total height of the tower tube is 98m.

[0061] like figure 1 , figure 2 As shown, the tower tube 1 includes the bottom tube section P1, the middle tube section 3, and the top tube section 4. The tower tube 1 is sequentially welded by the above three parts, and the middle tube section 3 is composed of nine identical middle tube sections P2 -P10 is welded in sequence, and the top cylinder section 4 is formed by sequentially connecting four identical top cylinder sections P11-P14;

[0062] like image 3 As shown, the construction method of tower tube 1 comprises the following steps:

[0063] 1) Steel plate surface pretreatment: firstly, conduct quality investigation on the steel plate used for manufacturing, determine the degree of corrosion on the steel plate surface, and then pass shot bla...

Abstract

The invention discloses a method for establishing a large floating type wind power station tower drum. The tower drum comprises a bottom drum joint, a middle drum joint and a top drum joint and is formed by welding the three parts in sequence. The middle drum joint is formed by welding a plurality of same middle barrel joint annular sections in sequence. The top drum joint is formed by connecting a plurality of same top barrel joint annular sections in sequence. By means of the method, the establishing period can be greatly shortened, the establishing difficulty is obviously lowered, the establishing precision is obviously improved, and economical benefits and social benefits are very impressive.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method of a tower of a large-scale floating wind power station, and belongs to the technical field of electric power equipment. Background technique [0002] Non-renewable energy sources such as coal, natural gas, oil, and nuclear energy are the main forms of energy supply in the world at present, but the environmental pollution (air pollution, nuclear residue radiation pollution, etc.) they bring is not optimistic. As a clean and renewable green energy, wind energy has high development efficiency, good economy, large-scale development conditions and commercialization prospects, and it has attracted more and more attention from all over the world. With the development of the global economy, the wind energy market has also developed rapidly. In recent years, the world wind energy market has been growing at a rate of 40% every year. It is estimated that in the next 20-25 ye...
