How does Tunnel Boring Machine (TBM) work? A Tunnel Boring Machine (TBM) is a specialised piece of equipment used to excavate tunnels through various types of soil and rock. It works by using a rotating cutter head with sharp disc cutters or tools that grind away the material in front of it, creating a tunnel of a precise diameter. As the cutter head rotates, the TBM simultaneously removes excavated material through a conveyor system and supports the newly created tunnel walls with precast concr

Tunnel Boring Machine (TBM) is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. There are different types of TBMs used in different ground condition. TBM selection is an important stage during the early stage of project and prior to construction. TBM should be designed in accordance with specific site requirements. Geology and ground water condition play an important role in TBM selection. Follow us at tunnel.engineering #tbmselection #t
