MOVING STRUCTURE IN TUNNEL

摘要

PURPOSE: A moving structure in a tunnel is provided to enable a worker to easily perform a work inside a tunnel by moving the moving structure along a rail. CONSTITUTION: A moving structure in a tunnel comprises a rail(10), a movable structure(20), a rail fixing unit, a wire, and a drive unit. The rail is installed on the inner surface of a tunnel(100) in a longitudinal direction. The movable structure is moved along the rail and provides a space required for a work. The rail fixing unit fixes the rail to the inner surface of the tunnel to support the load of the movable structure. The wire is connected to the movable structure to automatically move the movable structure. The drive unit winds and unwinds the wire.
