Safety Analysis and Reinforcement Measures of Transmission Tower

Abstract

After the investigation of the transmission tower, some common conditions were found: the inverted tower phenomenon occurred in recent years when there were short-term heavy rainfall, thunderstorm, strong wind and other strong convective weather. The area where the inverted tower phenomenon occurs and the surrounding environment have the same or similar conditions; The rod types with inverted tower are mainly 7722 (zs3) and 7727 (zgu2) (both of which are typical tower types designed in the 1970s). Therefore, the goal of reinforcement of transmission towers is proposed: the reinforcement scheme of ZS and zgu2 towers is reasonably proposed to achieve the requirements of reliable technology, simple construction, good reinforcement effect, small impact on the use function, economic rationality and neat appearance. According to the preliminary reinforcement measures and schemes of existing experience, we propose two solutions.
