Mechanized Construction Technology and Economic Analysis of Digging Pile Foundation for UHV Transmission Line in Mountainous and Hilly Area
The foundation is an important part of the transmission line,and the formulation and implementation of the foundation plan has an important influence on the engineering cost,construction period,labor safety and environmental protection requirements.In mountainous and hilly areas,mechanized construction of line foundation has always been a difficult problem.This paper combines 48 foundation digging pile mechanized construction in mountainous and hilly areas in a UHV AC line project(Hubei section)to conduct technical and economic comparison with conventional manual digging pile construction,aiming to provide reference for the promotion and application of digging pile mechanized construction in UHV transmission lines in mountainous and hilly areas.
