Gotthard Base Tunnel | Fred Haynes
They used four of the largest TBM (Tunnel Building Machines) the world has ever seen. The TBM were 19.25m (~62') in diameter. A rotating cutting wheel supported by lubricated disc cutters creates compressive stresses that fracture the rock in front of the TBM. The rock chips are transferred through openings in the TBM and removed on conveyor belts.اقرأ أكثر
