JP 2014-87417 A

In a tunnel, a fire hydrant device is generally installed without a box, for example, on a wall surface of a guards passage.
However, for example, in a tunnel in which the tunnel wall surface is made of a steel segment, such as a shield tunnel, the box cannot be removed, and other installation locations and installation methods are being studied. In that case, the most important thing is to reduce the thickness of the casing of the fire hydrant device.

In making this thinner, securing a wiring space in the fire hydrant device becomes a problem.
That is, the wiring in the fire hydrant device is diversified, and furthermore, since the electric cable needs to be secured with a curvature radius of a predetermined value or more without bending, if the housing has a depth as in the past, For example, it is possible to arrange the electric cable in a space on the rear side of the fire extinguisher so as to route the electric cable. However, when the thickness is reduced, there is no space on the rear side of the fire extinguisher and the electric cable cannot be routed.
For this reason, the wiring space of the electric cable becomes a bottleneck, and a case in which the thickness of the housing cannot be reduced has occurred.
