Building Blocks in a Foundation Pit ——Prefabrication and Assembly Construction Technology for Metro Stations
Prefabrication and Assembly Construction Technology for Metro Stations is a new construction method for underground metro stations, using precast concrete structural components and assembling them like "building blocks" on-site in a foundation pit, to quickly assemble into tunnel structures, minimizing on-site construction activities.
This innovative technology was originally developed to solve the problem of impossibility to construct open-excavated metro stations in severely cold winter of Changchun, by using industrialized construction method, but actual project experience using this technology has demonstrated that it also has outstanding advantages in various other environmental conditions.
