tunnel boring machine channel tunnel
The tunnel boring machine (TBM) used for the Channel Tunnel is a marvel of modern engineering, designed to bore through soil and rock to create tunnels with precision and speed. Its main functions include excavation, transportation of excavated material, and the support of the tunnel structure as it advances. Technological features of the TBM include a rotating cutting head, a thrust system for forward movement, and a conveyor belt for removing debris. The machine is equipped with sensors and advanced navigation systems to ensure accuracy. Its primary application is in the construction of large-scale tunnels for transportation, such as roadways, railways, and subways. The TBM for the Channel Tunnel is specifically designed to handle the challenging geology under the English Channel, making it one of the most sophisticated machines of its kind.
