Industry & Occupation
Classification
Summary
Factory worker who pours concrete into molds for tunnel lining segments, performs vibration and compaction, demolding, curing, and inspection.
Description
Segment Manufacturing Worker (Concrete) is a specialist who manufactures concrete segments used for lining in shield tunneling or tunnel construction. The work involves pouring ready-mixed concrete prepared in a concrete mixer into steel or FRP molds, removing air bubbles through vibration and compaction, and curing until the specified strength is achieved. After hardening, demolding from the molds, inspection of dimensions and surface conditions, and preparation for storage and shipment are performed. It also involves operating heavy machinery (forklifts, cranes, etc.) and using quality inspection equipment, with emphasis on safety and quality control in the workplace.
