Industry & Occupation
Classification
Summary
This occupation involves operating shield tunneling machines (TBM) in underground tunnel construction, handling everything from excavation to segment installation and machine operation management.
Description
Shield tunneling machine operators specialize in operating shield tunneling machines (TBM) used in underground tunnel construction. They precisely control the cutter rotation speed, thrust force, earth pressure, and other parameters from the control panel, performing excavation and segment installation simultaneously. During tunneling, they continuously monitor geological conditions and quickly adjust the machine or initiate emergency stops in case of troubles. Additionally, routine maintenance inspections, hydraulic system management, and coordination with the construction team and supervisors are essential. Work often involves long shifts in confined tunnel spaces, requiring advanced machine operation skills and a strong safety awareness.
Future Outlook
Demand will remain stable due to new urban infrastructure tunnels and aging infrastructure countermeasures, but a shortage of skilled workers due to the aging of highly skilled personnel is a challenge.
