Can be. Therefore, it is possible to efficiently and inexpensively mount the hardware on the tunnel after the construction.

However, from the viewpoint of more reliably and easily realizing the effects obtained by the present invention, it is preferable that each component of the hardware mounting system has the following configuration.

That is, it is preferable that the transport means travels using a groove formed in the invert of the tunnel in the tunnel extending direction as a guide. According to this, since a groove provided as a standard in the invert of the tunnel in the transport means is used as a guide, no separate rail equipment is required.

[0010] In this case, it is preferable that the transport means includes a transport vehicle on which hardware is to be held, and a roller that is rotatably supported by the transport vehicle in the groove.

The delivery means may include a gantry truck capable of freely storing hardware, a guide rail disposed in the gantry truck so as to protrude in front of and behind the gantry truck in a tunnel extending direction. It is preferable to comprise a hoist movable on a rail.

Further, as the attaching means, a traveling body,
It is preferable that the vehicle includes a manipulator mounted on the traveling body and to which a hardware can be freely attached and detached, and a work scaffold mounted on the traveling body and used for mounting hardware using the manipulator.

Still further, the loading means includes a crane, and a pallet on which the slewing can be freely performed by the crane and on which hardware is to be placed.
It is preferable that a portion related to the mounting of the metal object is a buffer member.
