The tile unit 9 can be attached to the frame 2 by fitting it into the hole of the fixing projection 13. Here, a hole through which the fixing projection 13 penetrates must be formed in the skin plate or the like that forms the formwork portion 2. However, since a relatively small hole is required, the concrete to be described later leaks from the hole. There is no fear.

Then, after the concrete is cast and a required curing time elapses, the solidification of the concrete is confirmed, and then the formwork portion 2 is released. This demolding can be performed by shrinking the holding portion 4 and the support member 6 and moving the form 2 to the center of the tunnel 7.

It shall be removed in advance from hole 3. FIG. 4 shows a state where the mold is removed. When the tile unit 9 removes the formwork portion 2, the back surface of the tile 12 adheres to the solidified concrete. Therefore, thereafter, the work of peeling off the mounting board 10 is performed manually. That is, the mounting substrate 10 is
Although 1 adheres to the surface of the plurality of tiles 12, only the mounting substrate 10 is manually peeled off. Then, the plurality of tiles 12 are attached to the inner surface side of the tunnel 7, and the interior finishing process of the inner surface of the tunnel is completed (see FIG. 5).
