tunnel boring machines

Tunnel boring machines (TBMs) are large, specialized készülékek used to excavate tunnels through various types of ground. They consist of a rotating cutting head at the front that breaks rock and soil, and a shield that supports the excavated tunnel walls. As the machine advances, it installs lining segments to reinforce the tunnel. TBMs are precise, efficient, and safer than traditional digging methods, making them ideal for urban infrastructure, transportation, and utility projects. Their design allows for continuous, controlled excavation deep underground with minimal surface disruption.
