| Zusammenfassung: | The invention belongs to the technical field of wind power prestress towers, and particularly relates to a prefabricated concrete draught fan tower barrel, tower barrel components and a connecting method. The connection of the prefabricated concrete draught fan tower barrel is completed through the six steps of connecting the sections of the two sides of a plurality of single prefabricated concrete components with reserved ducts to form the annular tower barrel components, connecting the multi-stage annular tower barrel components through prestress steel strands, splicing and hoisting the first-stage annular tower barrel component, splicing and hoisting the multi-stage annular tower barrel components, installing an anchoring device, stretching and drawing the prestress steel strands and sealing the surface. The prefabricated concrete draught fan tower barrel is not only convenient to transport, but also accelerates the splicing progress of the prefabricated components and is easy to construct and safe in stru |
