METHOD FOR MANUFACTURING TOWER BARREL SECTION, TOWER BARREL SECTION AND WIND POWER GENERATOR UNIT

摘要

Provided are a method for manufacturing tower tube section, a tower tube section and a wind turbine generator system. The method includes: forming a first tubular section (10) and a second tubular section (20); joining the first tubular section (10) and the second tubular section (20); forming a first notch (11) on the first tubular section (10) and a second notch (21) on the second tubular section (20), where an opening (30) is formed by the first tubular section (10) and second tubular section (20), and a height of the first notch (11) is less than a height of the first tubular section (10), and a height of the second notch (21) is less than a height of the second tubular section (20); forming a door frame (40), where the door frame (40) is embedded in the opening (30) and is welded to the first tubular section (10) and the second tubular section (20), and a door opening (43) is provided to the door frame (40).
