Shotcrete Worker
ふきつけコンクリートこう
Industry & Occupation
Classification
Summary
Civil engineering worker who uses specialized machinery to spray high-pressure concrete or mortar onto construction surfaces for tunnel lining, wall repairs, and forming waterproof and wear-resistant layers.
Description
Shotcrete workers are specialized laborers who apply concrete or mortar to concrete structures such as tunnels, retaining walls, and bridges using the shotcrete method with high-pressure spraying machines. They adjust fittings, hoses, and nozzles, manage material mixes, check spraying thickness, perform high-altitude work using safety harnesses, and implement dust control measures to ensure uniform layer thickness. On-site work is influenced by weather conditions and terrain, so they collaborate in teams to perform tasks quickly and accurately. They handle a wide range of applications, including repairing deteriorated areas, waterproofing treatments, and applying wear-resistant layers.
Future Outlook
With increasing needs for infrastructure aging countermeasures and tunnel repairs, stable demand is expected. On the other hand, as labor-saving and mechanization technologies advance, technicians may need to improve their machine operation skills.
