As a result, the upper surface 202 of the support body 201 and the upper surface 212 of the connecting body 211 are higher than the floor surface F. Assuming that the floor surface F is, for example, the road surface 1T of the roadway 1 of the tunnel T in which the fire hydrant device 100 is installed, and the upper surface 202 of the support 201 and the upper surface 212 of the connecting body 211 are assumed to be the road surface 2T of the observer passage 2, A test in which the elevating unit 20 of the fire hydrant device 100 is lifted and the housed hose 24 is stretched in the X1 direction on the upper surface 202 of the support 201 and the upper surface 212 of the connecting body 211 assumed to be on the road surface 2T of the guard passage 2. It can be carried out. Therefore, the test can be easily performed without performing large-scale construction work such as digging the floor F to install the fire hydrant device 100 .

Further, assuming that the floor surface F is the road surface 1T of the roadway 1, a test in which the hose 24 is stretched along the floor surface F assumed to be the road surface 1T of the roadway 1 is also performed without adding or installing a test jig. It is very convenient because you can

In addition, since the connecting bodies 211 and 221 are connected in a row from the supporting body 201 in the X1 direction, positional deviation of the supporting body 201 and the connecting bodies 211 and 221 is suppressed, and the test can be performed appropriately.

Also, the connection between the support 201 and the connecting bodies 211 and the connection between the plurality of connecting bodies 211 are fastened with bolts 205 and 215 . Therefore, by tightening the bolts 205 and 215, a simulated observer passage can be assembled with the support 201 and the plurality of connecting bodies 211, and a test can be conducted in which the hose 24 is extended from the fire hydrant device 100 in the X1 direction. Further, after the test is completed, the support 201 and the connecting body 211 can be disassembled and stored compactly by removing the bolts 205 and 215 . Furthermore, the bolt 205 connecting the support 201 and the connector 211 on the proximal side in the X1 direction is removed, and the support 201 is rotated around the vertical axis as indicated by the two-dot chain line in FIG. By connecting with the connecting body 211 in the X2 direction (see FIG. 8), a test of stretching the hose 24 by changing the drawing direction of the hose 24 with respect to the fire hydrant device 100 can be performed.

In addition, since the height of the support 201 and the height of the connecting body 211 are substantially the same, the upper surface 202 of the support 201 and the connecting body 211 are placed on the floor surface F. The upper surface 212 of the body 211 is made flush. Therefore, assuming that the upper surface 202 of the support member 201 and the upper surface 212 of the connecting member 211 are the road surface 2T of the observer passage 2, a test can be performed assuming the surface 2T of the observer passage 2 without steps.

It should be noted that the various shapes, combinations, etc., of the constituent members shown in the above-described embodiment are merely examples, and can be variously changed based on design requirements and the like without departing from the gist of the present invention.

For example, various configurations of the support body 201 and the connection body 211 can be adopted, and after assembling the outer shape with sheet metal or the like, the inside may be filled with concrete. Also, adjusters (not shown) capable of adjusting the height may be provided at the lower portions of the support body 201 and the connecting body 211, or casters (not shown) capable of rolling in the horizontal direction may be provided. Alternatively, a finishing material equivalent to the road surface 2T of the surveillance officer's passage 2 may be formed into a panel shape and detachably attached to the upper part of the support 201 and the upper part of the connecting body 211.

In addition, in the embodiment shown above, the lifting unit 20 is configured to be able to move up and down, but the present invention is not limited to this, and the configuration installed on the roadway 1 side of the observer passage 2 (embedded in the observer passage 2) configuration).
