PROBLEM TO BE SOLVED: To provide a joint material structure for a mold for tunnel lining that is especially effective when used with a telescopic-type mold for tunnel lining at a curved part of the tunnel.SOLUTION: A mold 1B is placed next to a mold 1A in a longitudinal direction of a tunnel, the mold 1A being used for curing tunnel lining concrete. A first joint material piece 3 is disposed along an outer periphery of an end plate 15 of the mold 1A facing an end plate 14 of the mold 1B. Also, a receiving member 2 is disposed on the end plate 14 of the mold 1B, the receiving member being made of a spring plate having a base end 21 fixed on the end plate 14 and a tip 2b extending obliquely toward the end plate 15 of the mold 1A. A joint material piece 4 is brought in contact with the joint material piece 3 while having an inner peripheral surface of the joint material piece 4 supported on an end surface 2a of an outer periphery of the receiving member 2, for forming a protrusion similar to a recessed cross-sectional shape of a joint of the lining concrete.SELECTED DRAWING: Figure 5 |
