By the way, in an urban tunnel made by the shield construction method or the like, the fire hydrant device cannot be embedded in the wall surface of the tunnel, and it is necessary to embed the fire hydrant device in the observer passage.

However, when a conventional fire hydrant device for opening the fire hydrant door is installed in the observer passage, there is a problem that when the fire hydrant door is opened, it exceeds the construction limit and pops out to the road side.

In order to solve this problem, for example, it is conceivable to install a fire hydrant device in which the fire hydrant door is slidably opened and closed. However, the fire hydrant device shown in the patent document slides down and opens the front door arranged on the upper front surface along the front surface of the fixed door on the lower front side, and therefore, on both sides of the fixed door on the lower front side, The guide groove of the upper door is exposed to the outside, and dust adheres to the guide groove exposed to the outside, and the handle provided at the bottom of the front door is operated to release the latch with the fixed door. However, there is a problem that the front door does not open due to dust adhering to the guide groove or stops in the middle.

Also, since the handle for opening the front door is planned to be installed at a high position such as the tunnel wall surface, when it is installed in the aisle's aisle, it will be quite close to the road surface, and the opening operation of the front door will be There is a problem that is hard to do.

Further, when a vehicle accident involving a fire occurs and the vehicle is stopped in front of the fire hydrant door, there is a problem that the stopped vehicle becomes an obstacle and the fire hydrant door cannot be opened to pull out the hose. ..

It is an object of the present invention to provide a fire hydrant facility in a tunnel that can easily and reliably open and close the front door when the fire hydrant storage box is installed on the side wall surface of the surveillance staff passage.

An upper door that is openable and closable in the opening on the top surface, a front door that is openably and closably installed in the upper opening on the front side of the fire hydrant storage box that is on the road side, and a rear door that is placed behind the front door. Since the slide opening/closing mechanism for opening/closing the front door is provided, the slide opening/closing mechanism for opening/closing the front door in the vertical direction is arranged in the housing on the back side of the front door and is not exposed to the outside. The dust that accompanies the passage of vehicles inside does not adhere, and the front door is reliably opened by the operation from the road side of the user when a fire occurs due to a vehicle accident, and it is easy and easy from the hose storage section. It is possible to pull out a hose with a nozzle to extinguish a fire. Further, when the foot is put on the fire hydrant storage box, the front door does not get caught when it slides and falls, which is highly safe.

(Effect of the slide opening/closing mechanism that slides to the back side of the fixed door)
Further, the front door is arranged at a position that closes the front opening formed at the upper part of the fixed door arranged at the lower part of the front surface of the fire hydrant storage box, and by the locking of the opening/closing operation part arranged at the front edge side of the upper door. It is held in the closed position, and the slide opening/closing mechanism slides down and opens on the back side of the fixed door when the front door is unlocked in conjunction with the opening operation of the upper door by the opening/closing operation section. Therefore, in addition to the effect that dust does not adhere to the slide opening and closing mechanism, the handle of the opening and closing operation part used for opening the front door is located on the upper front side of the fire hydrant storage box, and users from the road side can In the case of operation, since the handle is located at a position close to the road surface of the surveillance staff passage, the user can easily and easily open the upper door.

In addition, the upper door is arranged so that it can be opened and closed with the rear edge as the axis and can be opened and opened with the front edge as the axis. By opening the front door facing the slide and opening the upper door in the depth direction, the front upper part and the upper surface of the fire hydrant storage box are largely opened, and the hose with nozzle can be easily and easily pulled out from the hose storage part. You can extinguish the fire.

In addition, when the vehicle stops in front of the fire hydrant and the user cannot operate from the road side, the user climbs into the observer's aisle and bends over to open the upper door to the road side and then perform the opening operation. As a result, it is possible to easily and easily pull out the hose with a nozzle from the hose storage portion to extinguish the fire without being hindered by the stopped vehicle.

Also, when the upper door opens to the road side, it functions as a fence, so when pulling out the hose with a nozzle from the upper opening, the risk of the user falling to the road side is avoided, and the hose with the nozzle removed from the inside. It is also possible to prevent the nozzle from dropping on the road side.
