Abstract

The invention discloses a tower piece body, a tower section, a tower and a manufacturing method of the tower piece body. The manufacturing method of the tower piece body includes the following steps that the tubular tower section is provided, and the tower section comprises a longitudinally extending through hole and a tower wall surrounding the through hole; cutting is carried out sequentially along two or more pre-cutting lines of the tower section, a seam which extends in the axial direction and penetrates through the wall thickness of the tower is formed at each cut position, and a first cutting surface and a second cutting surface are formed in the tower wall and correspond to the seams; and connecting pieces are arranged, specifically, after the seam is formed after each time of cutting, the first connecting piece and the second connecting piece are arranged on the first cutting surface and the second cutting surface correspondingly, so that the first connecting piece and the second connecting piece are made to be at least partially opposite to each other, and the opposite parts are positioned on the inner side or the outer side of the tower wall.

Description

technical field [0001] The invention belongs to the technical field of tower tube manufacturing technology, and in particular relates to a tower tube sheet body, a tower tube section, a tower tube and a manufacturing method thereof. Background technique [0002] The tower of the wind power generation unit is composed of multiple tower sections axially superimposed and connected. The diameter and height of each tower section are huge, and transportation is difficult. In order to solve the problem of difficult transportation, a combined tower section has emerged, that is, each tower section is composed of multiple tower pieces. During construction, the tower body can be transported to the wind field, and the tower section can be assembled in the wind field, which avoids the problem of inconvenient transportation of the tower section. Connecting parts need to be provided at the connecting parts between the tower tube pieces, so that the tower tube pieces are assembled into tow...
