Description

The present invention relates to a fire hydrant storage box that is embedded under the road surface of a lifeguard passage in a tunnel having a road, and to a fire hydrant equipment equipped with the fire hydrant storage box.

Conventionally, fire hydrant devices have been installed as tunnel emergency equipment in tunnels such as expressways and motorways.The fire hydrant device is equipped with a fire hydrant door that can be opened freely, and a hose with a nozzle attached to the tip and a fire hydrant valve. Contains valves, including valves.

Fire hydrant devices are generally installed embedded in the tunnel wall surface at intervals of, for example, 50 meters along the tunnel side wall. In the event of a vehicle accident involving a fire, in a tunnel with a lifeguard passageway, users such as the driver of the accident vehicle should climb onto the lifeguard passageway using steps installed on the side of the lifeguard passageway and climb onto the tunnel wall. The fire hydrant door of the fire hydrant system installed in the fire hydrant system is opened forward and a hose with a nozzle is taken out to extinguish the fire.

The observer passageway is built as a sidewall passageway raised above the road surface, making it possible to safely inspect various equipment installed inside the tunnel, including fire hydrant systems, without interfering with vehicle traffic inside the tunnel. .

In addition, in tunnels without lifeguard passageways, users such as the driver of the accident vehicle should approach the fire hydrant device installed on the tunnel wall, open the fire hydrant door forward, and install the hose with a nozzle. We are trying to take out the fire and extinguish the fire.

By the way, urban tunnels made using the shield construction method or the like have a structure that does not allow for the installation of fire hydrant devices embedded in the tunnel walls, and it is necessary to install the fire hydrant devices embedded in the lifeguard passageways.

However, when a conventional fire hydrant device that opens the fire hydrant door forward is installed in a lifeguard passageway, there is a problem that when the fire hydrant door is opened, the fire hydrant door exceeds the building limit and protrudes onto the road side.

In order to solve this problem, for example, it is possible to install a fire hydrant device as shown in Patent Document 1, in which a fire hydrant door slides open and close. However, in the fire hydrant device shown in the patent document, the front door placed at the upper front side is slid down and opened along the front surface of the fixed door at the lower front side, and therefore, the front door is opened on both sides of the fixed door at the lower front side. The guide groove of the upper door is exposed to the outside, and if dust adheres to the guide groove exposed to the outside, the latch with the fixed door must be released by operating the handle provided at the bottom of the front door. However, there is a problem that the front door may not open or stop midway due to dust attached to the guide groove.

In addition, the handle for opening the front door is planned to be installed at a high position such as on the tunnel wall, so if it is installed in the lifeguard passage, it will be located quite close to the road surface, making it difficult to open the front door. There is a problem that is difficult to solve.

Furthermore, in the event of a vehicle accident involving a fire, if a vehicle is stopped in front of the fire hydrant door, there is a problem that the stopped vehicle will get in the way and make it impossible to open the fire hydrant door and pull out the hose. .

FIG. 16 is an explanatory diagram showing the water discharge control mechanism in cross section as seen from the road side together with the fire hydrant storage box on the observer's passage side.

(Configuration of water discharge control mechanism)
As shown in FIG. 16, a water discharge control mechanism storage section 150 is arranged in the management passage 20 which is located below the inner space of the lifeguard passage 14 where the fire hydrant storage box 30 is arranged.

The water discharge control mechanism storage section 150 is provided with a pressurized release type fire hydrant valve 152, an automatic pressure regulating valve 154, and a foam mixer 156 as valves that constitute the water discharge control mechanism.

A branch pipe 24a branched from the main water supply pipe 24 is connected to the primary side of a fire hydrant valve 152, and an automatic pressure regulating valve 125 and a foam mixer 156 are connected following the fire hydrant valve 152. The foam mixer 156 is connected to piping from a foam stock solution tank 158 , and the foam firefighting water obtained by mixing the foam stock solution at a predetermined ratio with the firefighting water flowing through the foam mixer 156 is supplied to the fire hydrant storage box 30 via the water supply pipe 25 . The water is supplied through a hose 60.

The fire hydrant valve 152 has a piston 162 slidably provided in a cylinder chamber 160 as a valve opening/closing mechanism for pressurizing and releasing, and a valve body 165 is connected to the piston 162 by a piston rod. A spring 164 is incorporated in the spring 164.

Fire hydrant valve 152 is normally closed. The fire hydrant valve 152 is closed by discharging fire extinguishing water from the cylinder chamber 160, reducing the pilot pressure to zero, pushing the piston 162 in the closing direction by the spring 164, and bringing the valve body 165 into contact with the valve seat. The flow paths on the next side and the secondary side are closed to be in a closed state.

To open the fire hydrant valve 152, fire extinguishing water is supplied to the cylinder chamber 160 to increase the pilot pressure, which causes the piston 162 to stroke outward against the spring 164, thereby separating the valve body 165 from the valve seat. The primary side and the secondary side are communicated with each other to create an open state.

In order to open the fire hydrant valve 152 by remote control, the operation box 66 of the fire hydrant storage box 30 is provided with a manual pilot valve 170 that is opened and closed by a fire hydrant valve opening/closing lever 68.

It is set up. Note that, instead of the pressure switch 175, a fire hydrant valve opening detection switch may be provided in the operation box 66, which is turned on by opening the fire hydrant valve opening/closing lever 68 and transmits a pump activation signal.

When the fire is extinguished and the fire extinguishing work is completed, the fire hydrant valve opening/closing lever 68 is returned to the closed position and the manual pilot valve 170 is closed. Subsequently, when the manual pilot valve 170 is closed, the water in the cylinder chamber 160 is slowly drained through the orifice 176, the pilot pressure is reduced to zero, and the piston 162 is pushed back by the spring 164 and brought into contact with the valve seat. , This closes the fire hydrant valve 152 and stops discharging fire extinguishing foam.

In addition, when inspecting the water discharge control mechanism, the person in charge goes to the water discharge control mechanism storage section 150 located in the management passage 20 and opens the manual release valve 172, and fire extinguishing water is supplied to the cylinder chamber 160. The pilot pressure is increased, allowing the fire hydrant valve 152 to be opened and a predetermined water discharge test to be performed. In this case, the manual drain valve 174 may be opened in order to close the fire hydrant valve 152.
