特徴とするトンネル覆工構造体。In a tunnel lining structure in which a tunnel hole is lined by assembling a curved concrete precast plate on the inner surface of an arch-shaped tunnel hole, a pair of left and right curves having a shape that divides the arch-shaped tunnel hole into two in the circumferential direction is used. The shaped precast plates are assembled in an arch shape around almost the entire circumference of the inner surface of the tunnel hole, the upper ends of the left and right pair of precast plates are fastened together by a connecting member, and the lower ends of each precast plate are fixed to the lower part of the inner wall of the tunnel hole. A tunnel lining structure characterized by:
