Problems solved by technology
[0004] However, when a single tube section is set as a structure composed of multiple arc-shaped components, the strength of the tube section itself is likely to be reduced, thereby reducing the overall strength of the tower. Therefore, it is necessary to provide a tube that is easy to transport and has good overall strength. Festival

The invention discloses a prefabricated concrete barrel section, a manufacturing method of the prefabricated concrete barrel section and a wind generating set tower barrel, relates to the wind power generation technology, and provides a barrel section which is convenient to transport and meanwhile guarantees that overall strength is good. The prefabricated concrete barrel section comprises at least two arc-shaped member which are connected in a matched mode; a plurality of closed-ring steel bars are arranged in each arc-shaped member at intervals; each closed-ring steel bar comprises an extending end located outside the corresponding arc-shaped member; a groove is formed in the end face of each arc-shaped member and is of the structure that the top end is through and the bottom end is closed; an adhering structure is arranged at the position, around the corresponding groove, of the end face of each arc-shaped member; when the adjacent arc-shaped members are connected in the matched mode, the extending ends of the closed-ring steel bars of the opposite surfaces of the corresponding arc-shaped members are arranged in a mutually staggered mode, and the corresponding adhering structures are used for adhering to the adjacent arc-shaped members and meanwhile sealing the opposite grooves; after the adjacent arc-shaped members are connected in the matched mode, a containing cavity of which the top end is open and the periphery is closed is formed by the opposite grooves and used for being filled with grouting materials. The prefabricated concrete barrel section and the manufacturing method thereof are mainly used in production of the wind generating set tower barrel.
Description
technical field [0001] The invention relates to wind power generation technology, in particular to a prefabricated concrete cylinder section, a manufacturing method thereof and a tower cylinder of a wind power generating set. Background technique [0002] A wind turbine (referred to as a fan) is a device that converts wind energy into electrical energy, including a tower and a wind turbine cabin fixed on the tower, which is connected to the blades of the fan. Among them, the tower as a support needs to ensure good stability, thereby ensuring the safety of the fan operation. [0003] In the prior art, due to the large structural size and overall height of the tower, the existing manufacturing process cannot meet the overall processing requirements. Therefore, the tower usually includes multiple tube sections, and then stacking and fixedly connecting multiple tube sections to form a tower. In practical applications, usually after the barrel section is manufactured, it is nec...
