underground tunnel boring machine
The underground tunnel boring machine is a state-of-the-art engineering marvel designed to excavate tunnels with precision and efficiency. This massive machine operates deep beneath the surface, primarily performing the main functions of drilling, cutting, and removing soil and rock as it progresses. Technological features include a rotating cutting head equipped with disc cutters or a shield that supports the tunnel face, reducing the risk of collapse. It also features advanced navigation systems for precision alignment and automatic conveyance systems to remove the excavated material. These machines are versatile and can be used in a range of applications, from constructing subways and road tunnels to creating utility corridors and hydroelectric projects.
