Research on the technical status of the segment-erection system for the full shield tunneling machine

Shield segment erecter is a key subsystem in the shield tunneling system,which is one typical complex hydraulic and mechatronic product.This paper discusses the working principle of the full shield segment-erection system and analyzes the technical status and existing problems of the segment erector at home and abroad.Then,According to the work features of the tunnel segment erector,the configuration design of the hybrid segment erector is proposed.
