Construction Technology for Underground Metro Tunnel

Tunnel Boring Machine (TBM) Tunnel boring machines, also known as TBM, are used as an alternative to drilling and blasting (D&B) methods in rock and conventional “hand mining” in soil. Tunnel boring machines have the advantages of limiting the disturbance to the surrounding ground and therefore they are able to produce a smooth tunnel wall.
