PROBLEM TO BE SOLVED: To provide a tunnel hydrant device capable of improving installation workability by disposing a hydrant valve unit in an automatic valve device storage space and connecting a fire hose to the hydrant valve unit with a flexible pipe.SOLUTION: A tunnel hydrant device 10 includes: a fire hose 16 and a hydrant valve opening/closing lever 17 that are stored in a hose storage space 13; and an automatic valve device 18 and a panel heater 19 that are stored in an automatic valve device storage space 14. A primary-side branch pipe 34 branched from a water supply main pipe 5 is drawn in the automatic valve device storage space 14 and connected to a primary-side flow path of the automatic valve device 18. A hydrant valve unit 25 including a hydrant valve 26 is connected to a branch pipe 24 branched from a part of the primary-side branch pipe 34 in the automatic valve device storage space 14 to be disposed in the automatic valve device storage space 14. A secondary side of the hydrant valve 26 is connected to the hydrant hose 16 via a flexible pipe 23. |
