混凝土电杆的防风固定张拉装置
By installing clamps and diagonal bracing structures at the bottom of the pole body, combined with the annular composite plate and the concrete in the foundation pit, a triangular stable system is formed, which solves the problem of concrete poles tilting or falling under strong winds and improves the pole's wind resistance and bending moment resistance.

AI Technical Summary
Existing concrete utility poles are prone to tilting or collapsing under strong winds, indicating insufficient foundation stability and an inability to effectively distribute wind loads, resulting in bending moments exceeding the design range.
Lower, middle, and upper clamps are installed at the bottom of the pole body, and connected to the horizontal plate by diagonal tie rods. Combined with the ring composite plate and the embedded rods, a triangular stable system is formed with the concrete in the foundation pit to enhance the pull-out resistance.
It improves the wind resistance of the poles, enhances the stability of the foundation, effectively disperses wind loads, and improves the bending moment resistance of the poles.
