Description

[0001] The present invention relates to the technical field related to wind towers, and in particular to a wind tower with high stability. Background Art

[0002] The wind tower combines steel and concrete. The lower reinforced concrete tower section is generally about 100m high and is equipped with a prestressed steel cable system. The overall structural rigidity is large, and the natural frequency and the unit operating frequency maintain a safe distance, which is not prone to resonance. It has obvious advantages in high shear wind speed areas and low wind speed high tower scenarios. The bottom of the truss tower is based on the truss, with high structural rigidity and high bearing capacity, which can effectively avoid resonance; the bottom frame structure material is reasonably distributed, which can reduce transportation volume and weight.

Due to different environmental geology, the wind tower sinks year by year, and the wind tower shows a micro-tilt, which affects the overall stability of the wind tower and causes resonance of the wind tower. When the wind tower tilts, it is difficult to perform secondary steel cable fixation on the outside. Summary of the Invention
