<P>PROBLEM TO BE SOLVED: To provide a device which allows a curing sheet to be easily and accurately attached to the surface of a tunnel lining concrete without use of a large-scale facility. <P>SOLUTION: A curing device 1 for a tunnel lining concrete comprises a pair of rails 4 and 4 which extend along the inner face of lining concrete 23 of a tunnel 21 in the circumferential direction of the tunnel and are arranged at a predetermined interval in the longitudinal direction of the tunnel, a sheet receiving frame 5 which is arranged between the pair of rails 4 and 4 at a predetermined distance away from the inner face of the lining concrete 23 along the inner face and holds a curing sheet 2 spread out in the circumferential direction of the tunnel at a temporary position away from the inner face of the lining concrete 23, and a roller 6 which is slidably arranged on the pair of rails 4 and 4 so as to bridge the pair of rails 4 and 4 and depresses the curing sheet 2 held at the temporary position by the sheet receiving frame 5 from the inside in the radial direction of the tunnel toward the inner face of the lining concrete. <P>COPYRIGHT: (C)2013,JPO&INPIT |
