Description

The present invention relates to a tunnel provided with a fire hydrant device embedded in a fire hydrant embedding portion that is partially open to the front wall of a guard passage provided facing the front wall on the road in the tunnel and a part of the passage surface. The present invention relates to an internal fire hydrant system, a fire hydrant device and a fire extinguisher box installed in an embedded part of a passageway for a guard.

Conventionally, fire hydrants installed in tunnels such as highways and motorways have a fire hydrant storage part in a housing with a fire hydrant door that can be opened freely, and a hose with a nozzle attached to the tip and valves are stored. For example, two fire extinguishers are stored in a fire extinguisher storage section having a fire extinguisher door that can be freely opened and closed.

Such fire hydrant devices are installed at intervals of, for example, 50 meters along the wall facing the guard passage provided in the tunnel. The observer passage is set up as a wall passage that is about 1 meter higher than the road surface, and it is possible to safely inspect various equipment including the fire hydrant installed in the tunnel without hindering vehicle traffic inside the tunnel. and

In the event of a vehicle accident involving a fire, users such as the driver of the accident vehicle should open the fire hydrant door of the fire hydrant system, pull out the hose with a nozzle, and operate the fire hydrant valve open/close lever to turn off the fire pump equipment. Fire extinguishing work can be performed by activating and discharging water.

However, in the case of such a conventional fire hydrant installed in a tunnel, since it was installed along the tunnel wall facing the passage of the guards, in the event of a fire due to a vehicle accident, the user would have to monitor from the road side. It is necessary to reach out to the fire hydrant installed on the tunnel wall beyond the passageway, open the fire hydrant door, and pull out the hose to extinguish the fire. Depending on the person, some people may have to go up to the guards' passage and operate it without being able to reach it. It was difficult to handle at times.

In order to solve this problem, the fire hydrant system can be embedded along the wall of the tunnel that faces the road to the guards. If there is a stopped vehicle in the way, it may be impossible to open the fire hydrant door and pull out the hose, or it may take time to operate the fire hydrant device. In addition, even if it is possible to handle the fire hydrant from the road surface side of the lifeguard passage, it is necessary to prepare an opening for handling the fire hydrant system on the road surface side of the lifeguard passage. In some cases, it interferes with traffic on the aisle.

To provide an in-tunnel fire hydrant facility, a fire hydrant device, and a fire extinguisher box that do not hinder traffic in a lifeguard passage even when a door having a door plate positioned on the passage surface side of the lifeguard passage is opened. aim.

In the present embodiment, when the fire hydrant front doors 28A-1 and 28A-2 and the fire extinguisher front door 32A are opened, they temporarily jump out to the road 15 side, but at the open position they move sideways along the front wall 14a. Therefore, even if a vehicle is stopped on the road 15 side, a sufficient space for opening the door is usually secured, and the door can be opened without being affected by the stopped vehicle. It does not interfere with the fire extinguishing work performed by pulling out the hose.

[Shutter door]
FIG. 14 is an explanatory diagram showing an embodiment of a fire hydrant device provided with a shutter door. As shown in FIG. 14, in the fire hydrant door of this embodiment, a fire hydrant shutter door 28C opens and closes between a vertical door opening located on the road 15 side and a horizontal door opening located on the lifeguard passage 14 side. freely set.

The same applies to the fire extinguisher door, and between the vertical door opening on the road 15 side and the horizontal door opening on the guard passage 14 side, a fire hydrant shutter door 32C is provided so as to be openable and closable. there is

The fire hydrant shutter door 28C secures a sufficient shutter surface along the road surface of the lifeguard passage 14 by minimizing the curvature at the corner portion thereof. In addition, when the fire hydrant shutter door 28C is in the closed state shown in the drawing, the horizontal part of the shutter becomes part of the guard passage 14. However, by adopting a structure in which metal shutter plates are continuously arranged, sufficient support strength is ensured. ing. The fire extinguisher shutter door 32C is also the same. Other configurations are the same as those of the embodiment shown in FIGS.

Also in this embodiment, when the fire hydrant shutter door 28C is opened upward, for example, the hose with the internal nozzle can be pulled out from the road 15 side or the lifeguard passage 14 side. Further, when the fire extinguisher shutter door 32C is opened upward, for example, the fire extinguisher can be pulled out from the road 15 side or the guard passage 14 side.

In particular, the fire hydrant shutter door 28C and the fire extinguisher shutter door 32C are advantageous over other embodiments in that they do not protrude outward at all when they are opened and closed.

[Unboxed structure of guard passage]
FIG. 15 is an explanatory view showing the unboxed part of the guard passage from the road side. In this embodiment, there is no duct in the lower part of the observer passage 14, it is filled with concrete, and all electrical conduits and the like are arranged in the management passage.

As shown in FIG. 15, such an observer passage 14 is preformed with a box-shaped cut-out portion 25 formed by hollowing out a portion extending from the road surface of the observer passage 14 to the front wall via the road shoulder. The fire hydrant device 16 shown in FIGS. 2 to 14 can be incorporated and installed from the front of the box opening 25 on the side of the road 15, facilitating the construction work.

[Modification of the present invention]
In the above-described embodiment, a fire hydrant system integrally provided with a fire extinguisher housing is taken as an example, but for example, a fire hydrant apparatus without a fire extinguisher housing may be used. In this case, the separately installed fire extinguisher box will have the door structure shown in the above embodiment.

Also, the hose outlet may be rotatably formed by using a flexible joint or the like.

Further, in the above embodiment, the hose storage section is arranged obliquely, but if the hose outlet is arranged obliquely, the hose storage section may be arranged horizontally or vertically other than obliquely. .

Further, the configuration and arrangement of the hoses of the fire hydrant equipment, the valves such as the fire hydrant valve, the reporting device, and other configurations shown in the above embodiments are arbitrary, and an appropriate configuration may be adopted.

Moreover, the present invention includes appropriate modifications that do not impair its purpose and advantages, and is not limited by the numerical values shown in the above embodiments.
