TUNNEL BORING MACHINE (TBM) METHOD
the tunnel section, boring distance, tunnel alignment and construction period. Both are closed-face type shield machines, meaning the "head" part of machine is "closed" and separated from the rear ... Completed tunnel with linings. From here, 1st stage concrete, rail track, ventilation, electrical and other cables, etc., starts installation.
