<P>PROBLEM TO BE SOLVED: To provide a structure for fixing a wet curing member for tunnel lining concrete, which allows for easy operation for connecting wet curing members and prevents the moisture of a wet curing layer from escaping from the connected site of the wet curing members. <P>SOLUTION: A quadrangular wet curing mat layer 15 is overlapped on the surface of a quadrangular base plate layer 14 so as to form a wet curing member 11 such that the base plate layer 14 sticks out from a side part 16a of the quadrangle by shifting the positions of the layers. The wet curing member 11 is inserted between a rod-like support member 13 and the inner peripheral surface 22a of a lining concrete 22, so that the wet curing mat layer 15 comes in close contact with the inner peripheral surface 22a of the lining concrete 22 for forming a wet curing layer 12. The wet curing members 11 are connected in a state that the side part 16a from which the base plate layer 14 sticks out is upwardly arranged in the circumferential direction from the lower part to the upper part along the arch-shaped portion of a tunnel 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
