Single-wall and double-wall combined tower drum structure

The invention relates to a single-wall and double-wall combined tower drum structure, and belongs to the technical field of high tower design and construction. The tower barrel double-wall section and the tower barrel single-wall section which form the tower barrel structure are respectively formed by connecting a plurality of barrel sections; k-shaped flanges are arranged between the shell rings; and a K-shaped flange is arranged between the tower drum double-wall section and the tower drum single-wall section. According to the invention, the equivalent radius-thickness ratio of the single-wall tower drum is greatly reduced, so that the allowable critical buckling stress level of the drum wall is improved, the material strength margin and the buckling capacity of the high tower drum wall are balanced to a greater extent, the material consumption is reduced, the construction cost is saved, and the application range of the all-steel flexible tower drum is expanded. The K-shaped flange is adopted for connection
