Summary:PROBLEM TO BE SOLVED: To provide a lining-concrete curing device superior in curing performance, having satisfactory assemblability, and capable of suppressing an increase in cost. SOLUTION: The curing device of secondary lining concrete 14 for curing in-situ concrete for tunnel lining comprises: a curing sheet 16 capable of tightly contacting with an inner wall surface of the secondary lining concrete 14; a curing support plate 18 arranged on a pit side of the curing sheet 16 for maintaining the curing sheet 16 in a state of tightly contacting with the inner wall surface of the secondary lining concrete 14; and a support material 20 for maintaining the curing support plate 18 in a state to be pressed to the side of the inner wall surface of the secondary lining concrete 14. The curing sheet 16 comprises of a moisture-retaining sheet containing a moisturing material for absorbing water for moisturing, and a heat-retaining sheet made of a heat-insulating member. The moisture-retaining sheet and the heat-retaining sheet are directly adhered to each other and integrated into a layered state. COPYRIGHT: (C)2011,JPO&INPIT
