Tunnel lining construction system and tunnel lining construction method

摘要

PROBLEM TO BE SOLVED: To enable automatic driving in a reinforcing bar assembly section in addition to automatic driving in an unreinforced section of lining. SOLUTION: Of a lining formwork 10, a plurality of driving ports 13 provided along a tunnel circumferential direction X2 on an inner peripheral surface 11a on the face side of a formwork body 11 located on the inner peripheral side of a tunnel wall surface 100 The driving nozzle 3 for driving concrete, the nozzle moving device 5 for moving the driving nozzle 3 in the tunnel circumferential direction X2 and attaching / detaching to / from the driving port 13, and the nozzle moving device 5 for moving the nozzle moving device 5 in the tunnel circumferential direction depending on the concrete driving situation. Provided is a tunnel lining construction system including a control unit 6 that moves to X2, selects a predetermined driving port 13, and controls the driving nozzle 3 to be attached / detached.
