Manufacturing method of circular cross-section concrete supporting structure of prefabricated wind turbine

The utility model discloses a circular cross-section concrete support structure of an assembled wind turbine, which comprises at least one structural unit. The structural unit includes a concrete tower section, longitudinal steel bars in the tower section, an upper flange, a lower flange, and an upper prestressed steel Stranded wires, lower prestressed steel strands, high-strength bolts, the longitudinal steel bars of the tower section are integrally cast with the upper and lower flanges to form an integral frame, and the concrete is poured between the upper and lower flanges, and the longitudinal steel bars of the tower section Wrapped inside, the upper and lower prestressed steel strands are pre-tensioned to connect multiple structural units circumferentially, and the upper and lower flanges are vertically connected by high-strength bolts to form multiple structural units. Round truncated cone-shaped whole. The utility model can effectively improve the integrity and installation efficiency of the concrete tower while meeting the requirements of factory segmented prefabrication and on-site overall assembly.
