Abstract

The foundation construction of overhead transmission lines in mountainous areas is the key and difficult point of the whole process of mechanized construction. Digging pile foundation is one of the most commonly foundation types. The economic benefit analysis of mechanical digging pile foundation is an important prerequisite for mechanized construction. Based on the characteristics of typical transmission lines in Fujian Province, this paper discusses the changing cost of mechanical digging pile foundation, and uses the single variable method to analyze the impact of human transport distance, road width, engineering quantity and geological conditions on the economic benefits of mechanized construction. The results show that the changes of engineering quantity and human transport distance have a great impact on the cost of mechanized construction. When the human transport distance of 110kV transmission line is less than 39m, and distance of 220kV transmission line is less than 39m, and distance of 500kV project is less than 214m, The mechanized construction is more economic than that of manual construction; The width of road construction has little impact on the cost of mechanized construction, and the impact of geological conditions on economic benefits increases with the increase of voltage level.
