Embodiment Construction

[0035] Such as figure 1 As shown, in this prestressed concrete wind power tower system, the upper end of the tower main body is connected to the wind power generator 7, which is characterized in that the tower main body consists of a concrete tower tube 2 at the lower part and a steel tower section 4 at the upper part The main body of the tower is fixed by a prestressed cable tie; the prestressed cable has a vertical prestressed bundle 3 arranged inside the lower concrete tower 2 and a vertical prestressed beam 3 arranged outside the lower concrete tower 2. The oblique prestressed cable 1; the upper end of the vertical prestressed beam 3 and the oblique prestressed cable 1 are anchored on the bottom flange 6 of the upper steel tower section, and the lower end of the oblique prestressed cable 1 is connected to the pullout The foundation 5 is fixedly connected, and the lower end of the vertical prestressed beam 3 is anchored to the base of the concrete tower 2 .

Abstract

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.

Description

technical field [0001] The invention relates to a wind power tower system, in particular to a prestressed concrete wind power tower system and a construction method thereof. Background technique [0002] The wind power tower belongs to the tower-mast structure. The tower structure itself has a large aspect ratio, and the cross-section of the structure is controlled by the bending capacity. The higher the tower, the greater the bending moment at the bottom of the tower, and the larger the tower cross-section. When wind power generation equipment is used in low wind speed areas, in order to obtain stable and reliable wind resources, a taller tower structure is required. The current steel towers are not suitable for wind power tower structures over 100m due to cost and rigidity issues. For such taller tower structures, a hybrid tower structure with a steel structure and a prestressed concrete lower part is currently used, or The entire wind power tower is made of prestressed c...
