New Developments and Applications in Rail Transit Construction Technology

Abstract

Combining with the practical engineering case, the paper summarizes the shallow mining method construction mechanism, construction methods and auxiliary technology. Aiming at the problems in the shield construction, the paper introduces the shield machine equipment’s latest comprehensive construction and technology, especially the shield technology dealing with the conglomerate stratum where the water and boulders is rich. It fills the domestic blank; Deep grouting and pipe roof reinforcement technology are aimed at the specific sources of risk; Whole cross-section of pallet trucks, electric vehicles, automatic metering and other new equipment have been widely applied to the construction site.
