EQUIPMENT FOR CURING LINING CONCRETE IN TUNNEL

PROBLEM TO BE SOLVED: To provide equipment for curing lining concrete in a tunnel, which can prevent the inside of the tunnel 1 and various types of equipment from being soiled with a fluid sprayed on the lining concrete 2, by making a fluid recovery tray 4 prevent the fluid from falling into the tunnel 1, and which can reuse and save the fluid for being sprayed on the lining concrete 2, by efficiently collecting the fluid, sprayed in the lining concrete 2, into a fluid recovery tank 13 and circulating the fluid in the fluid recovery tank 13 to a fluid supply pipe 11. SOLUTION: This equipment includes: the fluid supply pipe 11 which has a plurality of fluid outlets 12 for spraying the fluid on the lining concrete 2 molded along the longitudinal direction of the tunnel 1 on the inner periphery of the tunnel 1; the fluid recovery tray 4 for recovering the fluid which is discharged from each of the fluid outlets 12 of the fluid supply pipe 11; the fluid recovery tank 13 for recovering the fluid from the fluid recovery tray 4; and a pump 14 for supplying the fluid to the fluid supply pipe 11 from the fluid recovery tank 13.
