tunnel boring machine operator
Key facts
Delve into the earth and shape infrastructure as a tunnel boring machine operator! This skilled role involves operating complex machinery to create tunnels for transportation, utilities, and more, contributing to vital projects worldwide.
Tunnel boring machine operators are vital to large-scale tunnelling projects. You’ll be responsible for the safe and efficient operation of a tunnel boring machine (TBM), a sophisticated piece of equipment designed to excavate tunnels through various ground conditions. Your work involves constantly monitoring and adjusting the machine’s performance to ensure stability and accuracy, often working in challenging and confined environments.
- • Regulating the operation of the TBM, including adjusting torque and screw conveyor speed.
- • Monitoring tunnel stability and making necessary adjustments.
- • Installing reinforced concrete tunnel rings using remote controls.
