PROBLEM TO BE SOLVED: To provide a lining concrete curing structure capable of surely and inexpensively curing arch-shaped secondary lining concrete in a mountain tunnel with a simple structure. SOLUTION: This lining concrete curing structure 10 cures the arch-shaped secondary lining concrete 2 by covering an inner wall surface 12a of the arch-shaped secondary lining concrete 12 in the mountain tunnel 11 with a curing material 13. The inner wall surface 12a of the arch-shaped secondary lining concrete 12 is covered with a plurality of foaming styrene materials 13 as the curing material having a surface 13a of a shape corresponding to curvature of the inner wall surface 12a of the arch-shaped secondary lining concrete 12. Respective reverse surfaces 13b of the plurality of foaming styrene materials 13 are held by an arch-shaped air tube 14 as a holding member. COPYRIGHT: (C)2007,JPO&INPIT
