Research and Application of Self-propelled Trackless Construction Trolley for Subway Shield Tunnel
Relying on a Chengdu Metro Line Project,a trackless self-propelled intelligent construction trolley for tunnels was studied.It can safely walk on its own in the subway tunnel,automatically adjust its attitude,intel-ligent cruise,and park reliably.It reduces the safety risk,improves the construction efficiency,saves the con-struction cost,and has a good effect on the application of the project.This paper describes the research and ap-plication process of the self-propelled trackless construction trolley for subway shield tunnels.
