HOSE DRUM TRUCK

PROBLEM TO BE SOLVED: To use a hose drum truck in a steeply curved tunnel and to facilitate containing and delivery work for a hose by a method wherein at least two trucks are coupled together in series, a flexible hose is wound around drums longitudinally movable from a head truck to a rear truck and returned, and the flexible hose is contained and delivered along with longitudinal movement of the drum. SOLUTION: After a drum 30 is rewound to the movement limit of a drum support rail 4 of a truck 2 on the front side through winding operation of a winch 5, the rear ends of flexible hoses 40L for feeding and discharging are respectively coupled to a laying pipe, and the winch 5 is brought into a wire release state. When a shield machine is advanced for excavation, a hose drum truck 1 is advanced, the flexible hoses 40L for feeding and discharge deliver a drum 30 from the rear end of a rear truck 10. When the drum 30 reaches a limit of movement to a rear, after coupling with the laying pipe is uncoupled, the flexible hoses 40L for feed and discharge are contained in the hose drum truck 1.
