Abstract: With the maturity of China's ultra-high voltage technology system, a large number of transmission lines have been constructed one after another. Many of these routes are located in mountainous areas, facing difficulties in transportation, low lifting efficiency, high safety risks in high-altitude operations, and difficulties in construction during the rainy season. By analyzing the risks and difficulties faced by a certain project's two tower foundation construction and assembly tower construction process, including difficulties in transportation on mountainous roads and rainy seasons, narrow construction work surfaces, high risk factors for high-altitude operations, lightning and mechanical injuries, and hidden dangers of electric shock, a special construction safety plan for ultra-high towers was proposed. Targeted safety protection measures were proposed from personnel protection, mechanical protection, foundation construction protection, on-site protection, and environmental protection, effectively ensuring the safety of operators.
