Prestressed concrete wind power tower system and construction method thereof
The invention discloses a prestressed concrete wind power tower system and a construction method thereof. The prestressed concrete wind power tower system is characterized in that the upper end of a tower main body is connected to a wind driven generator; the tower main body is formed by sleeve connection of a concrete tower drum located at the lower part and a steel tower section located at the lower part; the tower main body is tied by prestressed cables for fixation; the prestressed cables comprise vertical prestressed tendons arranged inside the concrete tower drum at the lower part and slant prestressed cables arranged outside the concrete tower drum at the lower part; the upper ends of both the vertical prestressed tendons and the slant prestressed cables are anchored on a flange at the bottom of the steel tower section at the upper part; and the lower ends of the slant prestressed cables are fixedly connected to an anti-pulling foundation, and the lower ends of the vertical prestressed tendons are in anchor connection with a pedestal of the concrete tower drum. The wind power tower system has the beneficial effects that template engineering can be simplified to the maximum extent, the template cost of the tower structure is reduced, the prefabrication work in a factory prefabrication stage can be substantially simplified, and the efficiency of factory prefabrication is improved.
