Description

本発明は、ノズル付きホースを引き出して消火すると共にトンネル内の非常用設備の作動を進入車両に知らせて緊急停止させる非常覚知放水を行う消火栓装置に関する。
The present invention relates to a fire hydrant device that pulls out a hose with a nozzle and extinguishes fire and performs emergency notification water discharge that informs an approaching vehicle of the operation of emergency equipment in a tunnel and makes an emergency stop.

従来、自動車専用道路のトンネルには、トンネル内で発生する火災事故から人身及び車両を守るため、非常用設備が設置されている。このような非常用設備としては、火災の監視と通報のため火災検知器や非常電話が設けられ、また交通量が多く距離の長いトンネルにあっては、火災の消火や延焼防止のために消火栓装置やトンネル防護のための水噴霧ヘッドから水を散布させる水噴霧設備が設けられている。 Conventionally, an emergency facility has been installed in a tunnel for an automobile exclusive road in order to protect a person and a vehicle from a fire accident occurring in the tunnel. Such emergency equipment is equipped with fire detectors and emergency telephones for fire monitoring and reporting, and in heavy traffic tunnels, fire hydrants are used to extinguish the fire and prevent the spread of fire. A water spray facility is provided for spraying water from the water spray head for protecting the device and tunnel.

またトンネル内で事故などの異常が発生した場合、トンネル進入口に設置した信号機を赤にして進入を禁止したり、情報表示盤など異常発生を知らせるようにしている。
In addition, when an abnormality such as an accident occurs in the tunnel, the traffic light installed at the entrance to the tunnel is turned red to prohibit entry, or an information display panel is informed of the occurrence of the abnormality.

特開２００５−２１１２７９号公報JP 2005-2111279 A

しかしながら、このような信号機や情報表示盤を使用したトンネル進入を禁止する設備にあっては、高速道路や自動車専用道路では一般に信号機による交通規制は行われていないことから、信号機が赤に切り替わっても、それに気付くことなくトンネルに進入したり、赤信号に気付いても状況が把握できないため、そのまま進入してしまうことが想定され、重大な事故に繋がる恐れがある。またトンネルが長いと既に進入した車両には信号機は役立たない。 However, in facilities that prohibit tunnel entry using such traffic lights and information display panels, traffic lights are generally not regulated on expressways and motorway roads, so traffic lights turn red. However, even if you enter the tunnel without noticing it, you will not be able to grasp the situation even if you notice a red light, so it is assumed that you will enter as it is, which may lead to a serious accident. Also, if the tunnel is long, the traffic lights will not be useful for vehicles that have already entered.

また交通量の多いトンネルや距離の長いトンネルにあっては、信号機や情報表示盤が設置されるが、例えば２Ｋｍ以下といった短いトンネルにあっては、全てに信号機や情報表示盤を設置することは困難であり、このようなトンネル内で事故や車両火災などの異常が発生した場合、異常に気付くことなくトンネルに進入し、事故などの異常発生現場に近づいてから緊急停止することとなり、重大な事故に繋がる恐れがある。 Also, traffic lights and information display panels are installed in tunnels with heavy traffic and long distances. However, for short tunnels of 2 km or less, for example, it is not possible to install traffic lights or information display panels on all of them. If an abnormality such as an accident or a vehicle fire occurs in such a tunnel, it will enter the tunnel without noticing the abnormality, and it will stop immediately after approaching the site where the accident occurred There is a risk of an accident.

図１は本発明による非常覚知ヘッドを備えた消火栓装置の設置状態をトンネル平面で示した説明図である。 FIG. 1 is an explanatory view showing the installation state of a fire hydrant apparatus having an emergency awareness head according to the present invention in a tunnel plane.

図１において、道路２２が通るトンネル１２内の監視員通路が設けられた一方の側壁には、例えば５０メートル間隔で消火栓装置１０が設置されている。消火栓装置１０は扉内にノズル付ホースを収納しており、火災時に消火栓扉を開いてノズル付のホースを引き出し、消火栓弁開放レバーを操作することで放水を行う。消火栓装置１０からのノズル付ホースは、トンネル走行方向の左右２５ｍの範囲に放水できるように引き出すことができる。 In FIG. 1, fire hydrant devices 10 are installed, for example, at intervals of 50 meters on one side wall provided with a supervisor passage in the tunnel 12 through which a road 22 passes. The fire hydrant device 10 houses a hose with a nozzle in the door, and in the event of a fire, opens the fire hydrant door, pulls out the hose with a nozzle, and discharges water by operating the fire hydrant valve opening lever. The nozzle-equipped hose from the fire hydrant device 10 can be pulled out so that the water can be discharged in a range of 25 m on the left and right in the tunnel traveling direction.

消火栓装置１０には、火災時に操作して火災検出信号を出力する発信機が設けられ、発信機の近くには発信機設置場所を示す火災表示灯と、発信機の押釦操作に対する応答表示を行う応答表示灯が設けられている。消火栓装置１０にポンプ設備２０からの給水配管１６が接続され、防災受信盤１８と信号線接続している。 The fire hydrant device 10 is provided with a transmitter that operates in the event of a fire and outputs a fire detection signal. A fire indicator lamp that indicates the location of the transmitter is provided near the transmitter, and a response display to the push button operation of the transmitter is performed. A response indicator light is provided. A water supply pipe 16 from the pump facility 20 is connected to the fire hydrant apparatus 10 and is connected to the disaster prevention receiving board 18 through a signal line.

本実施形態にあっては、トンネル１２内に設置している消火栓装置１０に、トンネル１０内の道路２２を横切る方向に放水して非常覚知パターンを形成する非常覚知ヘッド１４を設けている。非常覚知ヘッド１４に対応して消火栓装置１０内には制御装置１１が設けられ、トンネル１２内での非常設備作動時に弁装置を開駆動制御して非常覚知ヘッド１４から放水させる。 In the present embodiment, the fire hydrant device 10 installed in the tunnel 12 is provided with an emergency awareness head 14 that discharges water in a direction across the road 22 in the tunnel 10 to form an emergency sense pattern. . A control device 11 is provided in the fire hydrant device 10 corresponding to the emergency awareness head 14, and the valve device is controlled to be opened and discharged from the emergency awareness head 14 when emergency equipment is operated in the tunnel 12.

ここで、制御装置１１は次の場合に非常覚知ヘッド１４から放水する。
（１）消火栓扉の開放を検出した場合
（２）消火栓弁の開放を検出した場合
（３）消火器扉の開放を検出した場合
（４）消火器の取り出しを検出した場合
（５）火災検知器により火災を検出した場合
（６）水噴霧設備の放水を放水開始前に知らせたい場合、 Here, the control device 11 discharges water from the emergency head 14 in the following case.
(1) When opening of the fire hydrant door is detected (2) When opening of the hydrant valve is detected (3) When opening of the fire hydrant door is detected (4) When removal of the fire extinguisher is detected (5) Fire detection (6) When you want to notify the water spray facility before the start of water discharge,

このような非常設備作動を検出するため、消火栓扉検出スイッチ、消火栓弁開放検出スイッチ、消火器扉検出スイッチ、消火器取り出し検出スイッチ、水噴霧放水検出スイッチなどが必要に応じて設けられる。勿論、これ以外の場合にも必要に応じて非常覚知ヘッド１４からの放水を行うことができる。各消火栓装置の制御装置１１は信号線を介してセンター等に配置された防災受信盤１８に接続されており、各スイッチの状態信号が防災受信盤１８で監視され、状態変化を警報や表示を行うことができる。防災受信盤１８は、火災時に消火栓装置１０の制御装置１１に制御信号を送ることもでき、例えばある消火栓装置の状態変化を検出した時に他の消火栓装置１０の制御装置１１に制御信号をおくって、状態表示や弁装置の駆動などの各種の制御を行うことができる。 In order to detect such an emergency operation, a fire hydrant door detection switch, a fire hydrant valve open detection switch, a fire extinguisher door detection switch, a fire extinguisher removal detection switch, a water spray discharge detection switch, and the like are provided as necessary. Of course, water can be discharged from the emergency awareness head 14 as necessary even in other cases. The control device 11 of each fire hydrant device is connected to a disaster prevention receiving board 18 disposed in the center or the like via a signal line, and the status signal of each switch is monitored by the disaster prevention receiving board 18 and an alarm or a display is displayed for a change in the state. It can be carried out. The disaster prevention receiving board 18 can also send a control signal to the control device 11 of the fire hydrant device 10 in the event of a fire. For example, when a change in the state of a certain fire hydrant device is detected, the control signal is sent to the control device 11 of another fire hydrant device 10. Various controls such as status display and driving of the valve device can be performed.

図１にあっては、入口から４台目の消火栓装置１０の付近で車両事故などにより火災が発生した場合を示しており、火災発生場所に近い消火栓装置１０の消火栓扉を開いてノズル付きホースを引き出して放水した場合、例えば消火栓扉の開放検出により制御装置１１が弁装置を開制御し、消火栓装置１０の外部に配管接続している非常覚知ヘッド１４から例えば棒状パターン１５による覚知放水を行う。棒状パターン１５による覚知放水の方向はトンネル１０内の道路を真横に横切る方向としている。なお、破線の棒状パターン１５ａに示すように、斜め前方に向けて放水してもよい。 FIG. 1 shows a case where a fire has occurred near the fourth fire hydrant device 10 from the entrance due to a vehicle accident or the like, and the fire hydrant door 10 of the fire hydrant device 10 close to the fire occurrence location is opened to provide a hose with a nozzle. When the water is drawn and discharged, for example, the control device 11 controls the opening of the valve device by detecting the opening of the fire hydrant door, and the water is discharged from the emergency head 14 connected to the outside of the fire hydrant device 10 by, for example, the bar pattern 15. I do. The direction of water discharge by the bar-shaped pattern 15 is a direction that crosses the road in the tunnel 10 directly. In addition, as shown to the broken-line rod-shaped pattern 15a, you may discharge water toward diagonally forward.

このような非常覚知ヘッド１４からの放水によりトンネル内の道路２２を横切る方向に非常覚知パターンを形成し、火災発生場所に進入してくる車両の運転者に前方で異常が発生していることを覚知させ、火災発生場所の手前で確実に制動停止させることが可能となる。 An emergency sense pattern is formed in the direction crossing the road 22 in the tunnel due to the water discharge from the emergency sense head 14, and an abnormality has occurred in the front of the driver of the vehicle entering the fire occurrence place. This makes it possible to stop the brakes reliably before the location of the fire.

即ち、火災場所に向かってくる車両の運手者は、道路を横切る棒状パターン１５の放水を見ることで異常事態の発生を覚知し、放水に気付かなくとも車両側面を横切るように放水を受けることで、異常事態の発生を覚知することができる。 That is, the vehicle operator who comes to the fire spot notices the occurrence of an abnormal situation by seeing the water discharge of the bar-shaped pattern 15 that crosses the road, and receives the water discharge across the side of the vehicle without noticing the water discharge. Thus, the occurrence of an abnormal situation can be known.

また棒状パターン１５による放水としたことで、非常覚知ヘッド１４からの放水量を異常発生の覚知に最小限必要な量、例えば消火栓装置に備えるノズル付きホースによる放水量と同程度もしくはそれ以下の量に抑え、ポンプ設備２０側に設けている貯水槽の貯水量に制約があっても必要な時間に亘り覚知放水ができ、かつ確実に運転者に異常を認識させることができる。 Further, since the water discharge is performed by the bar-shaped pattern 15, the water discharge amount from the emergency awareness head 14 is the minimum amount necessary for the detection of abnormality occurrence, for example, the same or less than the water discharge amount by the hose with a nozzle provided in the fire hydrant device. Even if there is a restriction on the amount of water stored in the water storage tank provided on the pump facility 20 side, the tactile water can be discharged for a necessary time, and the driver can be made sure of the abnormality.

また覚知放水は、火災発生場所の消火栓装置１０に設けた非常覚知ヘッド１５からの放水に限定されず、その手前の区間に設けた１又は複数の消火栓装置１０の非常覚知ヘッド１４からも放水する連動覚知放水を行っても良く、火災発生場所に向かってくる複数台の車両に同時に異常発生を覚知させることができる。このような連動覚知放水は、例えば発信機釦の操作で火災信号を受信した防災受信盤１８からの遠隔制御で行う。 Further, the tactile water discharge is not limited to the water discharge from the emergency head 15 provided in the fire hydrant device 10 at the place where the fire occurs, but from the emergency head 14 of one or more fire hydrant devices 10 provided in the section in front of it. It is also possible to perform an interlocking water discharge that discharges water, so that a plurality of vehicles coming to the location of the fire can be made aware of the occurrence of an abnormality at the same time. For example, such interlocking sensed water discharge is performed by remote control from the disaster prevention reception panel 18 that has received a fire signal by operating a transmitter button.

図２は図１に示したトンネルに設置される消火栓装置の説明図であり、図２（Ａ）に正面図を、図２（Ｂ）に消火栓扉を外した状態の内部構造を示している。図２（Ａ）において、消火栓装置１０は、筐体２６の前面に配置した化粧板２８の右側の扉開口に、消火栓扉３０と保守扉３２が設けており、その内部がホース収納空間及びバルブ類収納空間となっている。 2 is an explanatory view of the fire hydrant device installed in the tunnel shown in FIG. 1, FIG. 2 (A) shows the front view, and FIG. 2 (B) shows the internal structure with the fire hydrant door removed. .

ホースバケット４６の右側には、ホース取出口４８から引き出したホース５０の先端に装着しているノズル５２を横向きで着脱自在に保持している。 On the right side of the hose bucket 46, a nozzle 52 attached to the tip of the hose 50 drawn from the hose outlet 48 is detachably held sideways.

ホース収納空間の右側に配置したバルブ類収納空間には、ポンプ設備からの配管１６が接続される消火栓接続口からホース接続口に至る配管系統に、給水弁５４、消火栓弁５６（操作案内板の背面に位置）、自動調圧弁５８を含む放水バルブ系統と後の説明で明らかにする覚知放水用のバルブ系統を設けている。 In the valve storage space arranged on the right side of the hose storage space, a water supply valve 54 and a fire hydrant valve 56 (of the operation guide plate) are connected to a piping system from the fire hydrant connection port to which the piping 16 from the pump facility is connected to the hose connection port. A water discharge valve system including an automatic pressure regulating valve 58 and a valve system for a tactile water discharge which will be clarified in later explanation are provided.

消火栓弁に対しては消火栓弁開閉レバー５５が設けられ、これに対応して設けた銘板の裏側に配置された消火栓弁を開閉する。同時に消火栓弁開閉レバー５５の背後に設置している弁開閉検出スイッチがオンし、これによって図１の防災受信盤１８を経由してポンプ設備２０にポンプ起動信号が送られ、ポンプ設備が起動される。放水を停止する際には、消火栓弁開閉レバー５５を元の上向き位置に戻すと消火栓弁が閉じ、同時に弁開閉検出スイッチがオフとなってポンプ設備の運転停止が行われる。 A fire hydrant valve opening / closing lever 55 is provided for the fire hydrant valve, and opens and closes the fire hydrant valve disposed on the back side of the nameplate provided correspondingly. At the same time, the valve opening / closing detection switch installed behind the fire hydrant valve opening / closing lever 55 is turned on, whereby a pump activation signal is sent to the pump facility 20 via the disaster prevention receiving panel 18 of FIG. 1, and the pump facility is activated. The When stopping water discharge, returning the hydrant valve opening / closing lever 55 to the original upward position closes the hydrant valve and simultaneously turns off the valve opening / closing detection switch to stop the operation of the pump equipment.

また給水弁５４の手前にはポンプ起動スイッチ５７が配置される。給水弁５４及びポンプ起動スイッチ５７は消防隊が消火時に操作する機器であり、消火栓扉３０を開いても保守扉３２により隠されており、消火栓装置を操作しようとする一般ユーザに見せないことで、不要な混乱を起させないようにしている。 A pump start switch 57 is arranged in front of the water supply valve 54. The water supply valve 54 and the pump start switch 57 are devices that the fire brigade operates when extinguishing the fire, and even if the fire hydrant door 30 is opened, it is hidden by the maintenance door 32 and is not shown to the general user who wants to operate the fire hydrant device. , So as not to cause unnecessary confusion.

本実施形態では、消火栓弁開閉レバー５５の背後に設置している弁開閉検出スイッチ及びポンプ起動スイッチ５７からの信号も非常覚知ヘッドからの覚知放水を行う制御信号として使用することができる。 In the present embodiment, the signal from the valve opening / closing detection switch and the pump activation switch 57 installed behind the fire hydrant valve opening / closing lever 55 can also be used as a control signal for performing conscious water discharge from the emergency conscious head.

図３は本発明の消火栓装置に設けた弁装置として機能する放水バルブ系統の実施形態を示した説明図である。図３において、バルブ類収納空間には給水弁５４、消火栓弁５６、自動調圧弁５８、非常覚知放水弁６０、自動排水弁６２及び圧力センサ６４を設けている。 FIG. 3 is an explanatory view showing an embodiment of a water discharge valve system functioning as a valve device provided in the fire hydrant device of the present invention. In FIG. 3, a water supply valve 54, a fire hydrant valve 56, an automatic pressure regulating valve 58, an emergency notification water discharge valve 60, an automatic drain valve 62, and a pressure sensor 64 are provided in a valve storage space.

消火栓弁５６は給水源から伸びた給水配管に接続した給水弁５４の１次配管に分岐接続され、消火栓弁開閉レバー５５の操作により開閉される。自動調圧弁５８は消火栓弁５６の２次側に接続され、ホース５０側の放水圧力を規定圧に調整する。 The fire hydrant valve 56 is branched and connected to the primary pipe of the water supply valve 54 connected to the water supply pipe extending from the water supply source, and is opened and closed by operating the fire hydrant valve opening / closing lever 55. The automatic pressure regulating valve 58 is connected to the secondary side of the fire hydrant valve 56 and adjusts the water discharge pressure on the hose 50 side to a specified pressure.

非常覚知放水弁６０は電動弁を使用しており、覚知放水用の弁装置として機能し、消火栓弁５６の１次側から分岐した配管に設けられ、２次側を外部に引き出したヘッド配管２４を接続し、図１に示した制御装置１１により開閉制御される。ヘッド配管２４の先端には非常覚知ヘッド１４が接続されており、必要に応じて点線の非常覚知ヘッド１４に示すように、複数台設けることもできる。 The emergency tactile water discharge valve 60 uses an electric valve, functions as a valve device for tactile water discharge, is provided in a pipe branched from the primary side of the fire hydrant valve 56, and has a head that draws the secondary side to the outside. The pipe 24 is connected, and the opening / closing control is performed by the control device 11 shown in FIG. The emergency sensing head 14 is connected to the tip of the head pipe 24. If necessary, a plurality of emergency sensing heads 14 can be provided as shown by the dotted emergency sensing head 14.

また非常覚知放水弁６０は２次側に設けた圧力センサ６４の検出圧力を所定の放水圧力に保つように図１の制御装置１１により制御され、これによって非常覚知ヘッド１４からの放水圧力を規定圧に調整できる。 Further, the emergency notification water discharge valve 60 is controlled by the control device 11 of FIG. 1 so as to keep the detection pressure of the pressure sensor 64 provided on the secondary side at a predetermined discharge water pressure, whereby the discharge pressure from the emergency notification head 14 is controlled. Can be adjusted to the specified pressure.

自動排水弁６２は圧力が無いときに開放し、圧力が加わると閉鎖する弁であり、覚知放水後に非常覚知放水弁６０を閉鎖した場合に開放し、ヘッド配管２４の水を排水する。 The automatic drain valve 62 is opened when there is no pressure, and is closed when pressure is applied. The automatic drain valve 62 is opened when the emergency sensation water discharge valve 60 is closed after conscious discharge, and drains water from the head pipe 24.

図４は本発明の消火栓装置に設けた放水バルブ系統の他の実施形態を示した説明図であり、非常覚知ヘッドを消火栓装置に内蔵したことを特徴とする。 FIG. 4 is an explanatory view showing another embodiment of the water discharge valve system provided in the fire hydrant device of the present invention, and is characterized in that an emergency head is built in the fire hydrant device.

図４において、バルブ類収納空間に設けた給水弁５４、消火栓弁５６、自動調圧弁５８、非常覚知放水弁６０、自動排水弁６２及び圧力センサ６４は図３の実施形態と同じであるが、消火栓装置１０の筐体内に例えば３台の非常覚知ヘッド１４を収納し、ヘッド開口に相対して点線で示す放水開口２５を筐体前面に形成し、外部に棒状パターンの覚知放水を行うようにしている。 In FIG. 4, the water supply valve 54, the fire hydrant valve 56, the automatic pressure regulating valve 58, the emergency sense water discharge valve 60, the automatic drain valve 62 and the pressure sensor 64 provided in the valve storage space are the same as those in the embodiment of FIG. 3. For example, three emergency awareness heads 14 are accommodated in the housing of the fire hydrant device 10, a water discharge opening 25 indicated by a dotted line is formed on the front surface of the housing relative to the head opening, and a bar-shaped pattern of water discharge is provided outside. Like to do.

非常覚知ヘッド１４は例えば図２（Ａ）に示した保守扉２２の背後に配置され、ヘッド先端に相対した保守扉２２の位置に放水開口２５を形成する。非常覚知ヘッド１４から放水される放水パターンは消火栓装置１０を操作する人の邪魔にならない角度や向きに形成される。放水開口２５は蓋構造になっており、放水時のみ開口する。また、非常覚知ヘッド１４が放水時のみ消火栓装置１０から外部に伸びて露出する構成としても良い。 The emergency head 14 is disposed, for example, behind the maintenance door 22 shown in FIG. 2A, and forms a water discharge opening 25 at the position of the maintenance door 22 opposite the head end. The water discharge pattern discharged from the emergency awareness head 14 is formed at an angle or orientation that does not interfere with the person who operates the fire hydrant device 10. The water discharge opening 25 has a lid structure and is opened only during water discharge. Moreover, it is good also as a structure which the emergency awareness head 14 extends outside from the fire hydrant apparatus 10 only at the time of water discharge.

このように非常覚知ヘッド１４を消火栓装置１０に内蔵することで、外部のトンネル壁面などに対する非常覚知ヘッドの設置と配管が不要となり、設備工事を簡単にし、コストも低減できる。 By incorporating the emergency awareness head 14 in the fire hydrant apparatus 10 in this way, installation and piping of the emergency awareness head on the exterior tunnel wall surface and the like are not required, and the installation work can be simplified and the cost can be reduced.

次に本実施形態の非常覚知ヘッドによる非常覚知パターンについて図５〜図９を参照して説明する。 Next, an emergency sense pattern by the emergency sense head of this embodiment will be described with reference to FIGS.

図５は非常覚知ヘッドの棒状パターンによる横放水を示した説明図であり、図５（Ａ）はトンネル断面、図５（Ｂ）はトンネル平面を示している。 5A and 5B are explanatory views showing lateral water discharge by a stick-like pattern of the emergency head, FIG. 5A shows a tunnel cross section, and FIG. 5B shows a tunnel plane.

図５において、非常覚知ヘッド１４は放水量を覚知に必要な必要最小限とするため棒状パターン１５で放水しており、本実施形態にあっては、図５（Ａ）のトンネル断面に示すように、消火栓装置１０からのヘッド配管２４に接続したトンネル側壁の非常覚知ヘッド１４から道路を真横に横切る方向に棒状パターン１５で放水し、且つ図５（Ｂ）のトンネル平面に示すように、走行方向に対しても真横に横切る方向に棒状パターン１５を放水している。 In FIG. 5, the emergency awareness head 14 discharges water with a bar-like pattern 15 in order to minimize the amount of water discharge necessary for awareness, and in this embodiment, the emergency cross section 14 has a tunnel cross section in FIG. As shown in the figure, water is discharged from the emergency head 14 on the side wall of the tunnel connected to the head pipe 24 from the fire hydrant device 10 in the direction of right across the road with a bar-like pattern 15 and shown in the tunnel plane of FIG. In addition, the rod-like pattern 15 is discharged in a direction transversely to the running direction.

このような棒状パターン１５の横放水により、トンネル１２内を走行してくる車両は進行方向の道路を横切る棒状パターン１５による放水を見ることで異常事態の発生を覚知し、放水に気付かなくとも車体側面を横切るように放水を受けることで、異常事態の発生を覚知することができる。 By such horizontal discharge of the bar-shaped pattern 15, a vehicle traveling in the tunnel 12 can recognize the occurrence of an abnormal situation by seeing the water discharge by the bar-shaped pattern 15 that crosses the road in the traveling direction, and does not notice the discharge. By receiving water discharge across the side of the vehicle body, it is possible to recognize the occurrence of an abnormal situation.

また火災発生によりトンネル上部に煙層が形成されるが、非常覚知ヘッド１４からの棒状パターン１５は道路２２の路面に近い位置での横放水であるため、放水によって煙層が乱されてトンネル全体に煙が広がってしまうことはない。 In addition, a smoke layer is formed in the upper part of the tunnel due to the occurrence of a fire. However, since the rod-shaped pattern 15 from the emergency awareness head 14 is lateral water discharge at a position close to the road surface of the road 22, the smoke layer is disturbed by the water discharge. Smoke does not spread throughout.

さらに、棒状に放水された消火用水は、トンネルの対向壁面に放水されるため、壁面下方に設けた排水口に排水されるため、道路に滞留することがないため、車両が滑るなどの二次災害を極力防ぐことも可能となる。 Furthermore, since the fire-fighting water discharged in a rod shape is discharged to the opposite wall surface of the tunnel, it is drained to a drain outlet provided below the wall surface, so it does not stay on the road, so secondary vehicles such as slipping It is also possible to prevent disasters as much as possible.

棒状パターン１５の高さは特に限定されないが、一般的な車両の高さよりも少し上の高さ位置に設定した場合は、通行する車に消火用水がかかることがなく、運転者の視界を妨げることがない。 The height of the bar-shaped pattern 15 is not particularly limited. However, when the height is set to be slightly higher than the height of a general vehicle, fire-fighting water is not applied to the passing vehicle, which hinders the driver's view. There is nothing.

図６は非常覚知ヘッドの棒状パターンによる斜め放水を示した説明図である。本実施形態にあっては、図６（Ａ）のトンネル断面に示すように、消火栓装置１０からのヘッド配管２４に接続したトンネル側壁の非常覚知ヘッド１４からの棒状パターン１５を道路を横切る方向に放水し、且つ図６（Ｂ）のトンネル平面に示すように、走行方向に対して棒状パターン１５を斜め方向に放水している。 FIG. 6 is an explanatory view showing oblique water discharge by the rod-like pattern of the emergency head. In this embodiment, as shown in the tunnel cross section of FIG. 6 (A), the rod-shaped pattern 15 from the emergency head 14 on the side wall of the tunnel connected to the head pipe 24 from the fire hydrant device 10 crosses the road. As shown in the tunnel plane of FIG. 6 (B), the rod-shaped pattern 15 is discharged obliquely with respect to the traveling direction.

このような棒状パターン１５の斜め放水により、トンネル１２内を走行してくる車両は進行方向から斜めに横切るから棒状パターン１５による放水を見ることで異常事態の発生を覚知し、放水に気付かなくとも車体を斜めに横切るように放水を受けることで、異常事態の発生を覚知することができる。 Due to the oblique water discharge of the rod-shaped pattern 15, the vehicle traveling in the tunnel 12 crosses obliquely from the traveling direction, so that the occurrence of an abnormal situation is noticed by seeing the water discharge by the rod-shaped pattern 15, and the water discharge is not noticed. In both cases, it is possible to recognize the occurrence of an abnormal situation by receiving water discharge obliquely across the vehicle body.

また火災発生によりトンネル上部に煙層が形成されるが、非常覚知ヘッド１４からの棒状パターン１５は道路２２の路面に近い位置での斜め放水であるため、放水によって煙層が乱されてトンネル全体に煙が広がってしまうことはない。 In addition, a smoke layer is formed in the upper part of the tunnel due to the occurrence of a fire. However, since the rod-shaped pattern 15 from the emergency head 14 is an oblique water discharge near the road surface of the road 22, the smoke layer is disturbed by the water discharge and the tunnel is disturbed. Smoke does not spread throughout.

図７はトンネル内に非常覚知ヘッドを配置した実施形態における棒状パターンによるクロス放水を示した説明図である。 FIG. 7 is an explanatory view showing cross water discharge by a bar-shaped pattern in an embodiment in which an emergency head is arranged in a tunnel.

図７（Ａ）のトンネル断面において、トンネル１２の側壁に消火栓装置１０からのヘッド配管２４に接続した非常覚知ヘッド１４を配置し、更に、ヘッド配管２４をトンネル上部から反対側のトンネル側面に配管し、そこに非常覚知ヘッド１４を配置し、トンネル両側の側壁に設置した非常覚知ヘッド１４から道路を横切る方向に棒状パターン１５を放水することでクロス放水とし、且つ図７（Ｂ）のトンネル平面に示すように、両側に配置した非常覚知ヘッド１４から走行方向に対しても斜めに棒状パターン１５を放水することでクロス放水としている。 7A, the emergency head 14 connected to the head pipe 24 from the fire hydrant apparatus 10 is arranged on the side wall of the tunnel 12 in the tunnel cross section, and further, the head pipe 24 is placed on the side of the tunnel opposite to the upper side of the tunnel. Piping, the emergency head 14 is disposed there, and the bar pattern 15 is discharged from the emergency head 14 installed on the side walls on both sides of the tunnel in the direction across the road. As shown in the tunnel plane, cross-water discharge is performed by discharging the rod-shaped pattern 15 obliquely in the traveling direction from the emergency heads 14 arranged on both sides.

このような棒状パターン１５の２本のクロス放水により、トンネル内を走行してくる車両は進行方向にクロスして横切る棒状パターン１５による放水を見ることで異常事態の発生を覚知し、放水に気付かなくとも車体を斜めに横切るように放水を受けることで、異常事態の発生を覚知することができる。 By such two cross water discharges of the bar-shaped pattern 15, the vehicle traveling in the tunnel notices the occurrence of an abnormal situation by seeing the water discharge by the bar-shaped pattern 15 that crosses and crosses in the traveling direction, and discharges water. Even if you do not notice, you can be aware of the occurrence of an abnormal situation by receiving water discharge diagonally across the car body.

またトンネル走行方向に所定間隔で配置されている複数の消火栓装置１０に設けた非常覚知ヘッド１４から同時にクロス放水を行うと、トンネル前方に複数のクロス放水パターンが浮かび上がり、異常事態の発生を確実に覚知できる。またクロス放水は路面に近い位置の放水となるため、トンネル上部に形成される煙層を乱すようなことはない。 In addition, if cross water discharge is performed simultaneously from the emergency heads 14 provided in the plurality of fire hydrant devices 10 arranged at predetermined intervals in the tunnel traveling direction, a plurality of cross water discharge patterns emerge in front of the tunnel, and an abnormal situation occurs. You can be sure. Moreover, since the cross water discharge becomes a water discharge near the road surface, the smoke layer formed at the upper part of the tunnel is not disturbed.

また、クロス放水においても、運転者の視界を妨げることを防ぐことができる。 Further, it is possible to prevent the driver's view from being obstructed even in cross water discharge.

図８は複数の非常覚知ヘッドを配置した実施形態における棒状パターンによるマルチ放水を示した説明図であり、３台の非常覚知ヘッドを設けた場合を例にとっている。 FIG. 8 is an explanatory view showing multi-water discharge by a bar-shaped pattern in an embodiment in which a plurality of emergency detection heads are arranged, and an example in which three emergency detection heads are provided is taken as an example.

図８（Ａ）のトンネル断面においては、トンネル１２の側壁に消火栓装置１０からのヘッド配管２４に接続した３台の非常覚知ヘッド１４を配置し、道路２２を横切る方向に棒状パターン１５を放水している。また図８（Ｂ）のトンネル平面にあっては、３台の非常覚知ヘッド１４から棒状パターン１５を、真横に横切る方向、異なる斜め方向にマルチ放水している。 8A, three emergency heads 14 connected to the head pipe 24 from the fire hydrant device 10 are arranged on the side wall of the tunnel 12, and the rod-shaped pattern 15 is discharged in a direction crossing the road 22. doing. Further, in the tunnel plane of FIG. 8B, the multi-water discharge is performed from the three emergency sensing heads 14 in the direction transverse to the side and in different oblique directions.

このような棒状パターン１５を用いたマルチ放水により、トンネル内を走行してくる車両は棒状パターン１５による放水を見ることで異常事態の発生を覚知することができる。一本の放水パターンよりも放水により気づきやすい。もし放水に気付かなかったとしても放水を車体に受けるようにパターン位置を設定した場合は、車体に受けた音や水滴で異常事態の発生を覚知することができる。また路面に近い位置の放水とすれば、トンネル上部に形成される煙層を乱すようなことはない。たとえ、煙層に放水パターンが形成されたとしても、棒状パターンであるから煙層をかき乱す程の威力がない。 By the multi-water discharge using such a bar-shaped pattern 15, a vehicle traveling in the tunnel can recognize the occurrence of an abnormal situation by watching the water discharge by the bar-shaped pattern 15. It is easier to notice by water discharge than a single water discharge pattern. If the pattern position is set so that the vehicle body receives the water discharge even if the water discharge is not noticed, the occurrence of an abnormal situation can be recognized by the sound and water droplets received by the vehicle body. Moreover, if the water is discharged near the road surface, the smoke layer formed at the upper part of the tunnel will not be disturbed. Even if a water discharge pattern is formed in the smoke layer, it is a rod-shaped pattern, so there is not enough power to disturb the smoke layer.

図９は複数の非常覚知ヘッドを配置した棒状パターンによるマルチ放水の他の実施形態を示した説明図であり、３台の非常覚知ヘッドを設けた場合を例にとっている。 FIG. 9 is an explanatory view showing another embodiment of multi-water discharge by a bar-shaped pattern in which a plurality of emergency detection heads are arranged, and an example in which three emergency detection heads are provided is taken as an example.

本実施形態では、図９（Ａ）のトンネル断面についても、消火栓装置１０からのヘッド配管２４に接続した３台の非常覚知ヘッド１４から、道路２２を真横に横切る方向、異なる斜め方向にマルチ放水している。また図９（Ｂ）のトンネル平面についても、３台の非常覚知ヘッド１４から棒状パターン１５を、真横に横切る方向、異なる斜め方向にマルチ放水している。 In the present embodiment, the tunnel cross section of FIG. 9A is also multi-directional in the direction across the road 22 from the three emergency sensing heads 14 connected to the head pipe 24 from the fire hydrant device 10 in different diagonal directions. The water is discharged. Also, the tunnel plane of FIG. 9B also multi-sprays the bar-shaped pattern 15 from the three emergency sensing heads 14 in a direction transverse to the side and in different oblique directions.

このような棒状パターン１５を用いたマルチ放水により、トンネル内を走行してくる車両は棒状パターン１５による放水を見ることで異常事態の発生を覚知し、放水に気付かなくとも放水を車体に受けることで、異常事態の発生を覚知することができる。 By such multi-water discharge using the bar-shaped pattern 15, a vehicle traveling in the tunnel recognizes the occurrence of an abnormal situation by watching the water discharged by the bar-shaped pattern 15 and receives the water discharge even if the water discharge is not noticed. Thus, the occurrence of an abnormal situation can be known.

なお、図５乃至図９に示した非常覚知ヘッド１４の棒状パターンによる放水は、水平放水以外にトンネル上部の煙層を乱さない範囲での上向き放水や複数の非常覚知ヘッドからのマルチ放水を交差されたクロス放水など適宜の放水パターンとすることができる。 In addition, the water discharge by the rod-like pattern of the emergency head 14 shown in FIGS. 5 to 9 is the upward water discharge within a range that does not disturb the smoke layer above the tunnel other than the horizontal water discharge and the multi-water discharge from a plurality of emergency heads. Can be made into an appropriate water discharge pattern such as cross water discharge.

図１０は本発明の消火栓装置に設けた放水バルブ系統の他の実施形態を示した説明図である。図１０において、バルブ類収納空間には給水弁５４、自動調圧弁５８、消火栓弁５６、非常覚知放水弁６０、自動排水弁６２及び圧力スイッチ６８を設けている。 FIG. 10 is an explanatory view showing another embodiment of the water discharge valve system provided in the fire hydrant apparatus of the present invention. In FIG. 10, a water supply valve 54, an automatic pressure regulating valve 58, a fire hydrant valve 56, an emergency notification water discharge valve 60, an automatic drain valve 62, and a pressure switch 68 are provided in a valve storage space.

自動調圧弁５８は給水配管を接続した給水弁５４の１次配管に分岐接続され、ホース５０側の放水圧力を規定圧に調整する。消火栓弁５６は自動調圧弁５８の２次側に接続され、消火栓弁開閉レバー５５の操作により開閉される。非常覚知放水弁６０は電動弁を使用しており、自動調圧弁５６の２次側の分岐配管に設けられ、２次側に外部に引き出したヘッド配管２４に接続し、図１の制御装置１１により開閉制御される。 The automatic pressure regulating valve 58 is branched and connected to the primary piping of the water supply valve 54 to which the water supply piping is connected, and adjusts the water discharge pressure on the hose 50 side to the specified pressure. The fire hydrant valve 56 is connected to the secondary side of the automatic pressure regulating valve 58 and is opened and closed by operating the fire hydrant valve opening / closing lever 55. The emergency notification water discharge valve 60 uses an electric valve, and is provided in the branch pipe on the secondary side of the automatic pressure regulating valve 56, connected to the head pipe 24 drawn to the outside on the secondary side, and the control device of FIG. 11 is controlled to open and close.

非常覚知放水弁６０は自動調圧弁５８により規定圧に調整された消火用水を非常覚知ヘッド１４に供給することから、図３の実施形態のように圧力センサ６４を設けて圧力制御する必要はなく、その分、簡単にできる。圧力スイッチ６８は非常覚知ヘッド１４への加圧消火用水の供給時の圧力を受けてオンし、例えば図１の防災受信盤１８に検出信号を送って非常告知放水を報知させる。 Since the emergency sense water discharge valve 60 supplies the fire extinguishing water adjusted to the specified pressure by the automatic pressure regulating valve 58 to the emergency sense head 14, it is necessary to provide a pressure sensor 64 and control the pressure as in the embodiment of FIG. No, it ’s easy. The pressure switch 68 is turned on in response to the pressure at the time of supplying pressurized fire-extinguishing water to the emergency awareness head 14, and for example, sends a detection signal to the disaster prevention receiver 18 of FIG.

自動排水弁６２は非常覚知放水弁６０の閉鎖による覚知放水停止時にヘッド配管２４内の消火用水を排水させる。 The automatic drain valve 62 drains the fire-extinguishing water in the head pipe 24 when the alert water discharge is stopped by closing the emergency water discharge valve 60.

図１１は本発明の消火栓装置に設けた放水バルブ系統の他の実施形態を示した説明図である。図１１において、バルブ類収納空間には給水弁５４、消火栓弁５６、自動調圧弁５８を設け、自動調圧弁５８の２次側から分岐して外部に引き出したヘッド配管２４に非常覚知ヘッド１４を接続している。 FIG. 11 is an explanatory view showing another embodiment of the water discharge valve system provided in the fire hydrant apparatus of the present invention. In FIG. 11, a water supply valve 54, a fire hydrant valve 56, and an automatic pressure regulating valve 58 are provided in the valve housing space, and the emergency head 14 is connected to the head pipe 24 branched from the secondary side of the automatic pressure regulating valve 58 and drawn to the outside. Is connected.

本実施形態にあっては、消火栓弁５６が非常覚知ヘッド１４からの放水を行う覚知放水弁としての機能を兼用しており、消火栓弁開閉レバー５５を開操作すると、ホース５０側に調圧された消火用水が供給されると共に非常覚知ヘッド１４にも供給されて覚知放水が行われる。 In the present embodiment, the fire hydrant valve 56 also functions as an awareness water discharge valve for discharging water from the emergency awareness head 14, and when the fire hydrant valve opening / closing lever 55 is opened, the fire hydrant valve 56 is adjusted to the hose 50 side. Pressurized water for fire extinguishing is supplied and also supplied to the emergency awareness head 14 to perform awareness discharge.

ここで、ノズル付きホースからの放水と非常覚知ヘッド１４からの非常覚知放水を別々に行うためには、ホース先端に装着しているノズルとして開閉レバー付きのノズルを使用し、ノズルを常時閉鎖状態して消火栓装置に配置しておけば、非常覚知放水を行ってもノズルから放水されないようにできる。 Here, in order to perform the water discharge from the hose with the nozzle and the emergency water discharge from the emergency head 14 separately, a nozzle with an opening / closing lever is used as the nozzle attached to the tip of the hose, and the nozzle is always used. If it is placed in a fire hydrant device in a closed state, it is possible to prevent water from being discharged from the nozzle even if emergency alert water discharge is performed.

本実施形態は通常の放水バルブ系統をそのまま利用することで、簡単で低コストとなる構成により覚知放水ができる。 In the present embodiment, by using a normal water discharge valve system as it is, the tactile water discharge can be performed with a simple and low-cost configuration.

図１２は本発明の消火栓装置に設けた放水バルブ系統の他の実施形態を示した説明図である。図１２において、バルブ類収納空間には給水弁５４、電動弁を用いた消火栓弁７０、自動調圧弁５８を設け、自動調圧弁５６の２次側から分岐して外部に引き出したヘッド配管２４に非常覚知ヘッド１４を接続している。

FIG. 12 is an explanatory view showing another embodiment of the water discharge valve system provided in the fire hydrant apparatus of the present invention. In FIG. 12, a water supply valve 54, a fire hydrant valve 70 using an electric valve, and an automatic pressure regulating valve 58 are provided in a valve storage space, and the head piping 24 branched from the secondary side of the automatic pressure regulating valve 56 and drawn to the outside. An emergency head 14 is connected.

電動弁を用いた消火栓弁７０は消火栓開閉レバーによるスイッチ操作または押釦スイッチの操作などで開閉制御することになる。 The fire hydrant valve 70 using an electric valve is controlled to be opened and closed by a switch operation using a fire hydrant opening / closing lever or a push button switch.

本実施形態にあっても、電動弁を用いた消火栓弁７０が非常覚知ヘッド１４からの放水を行う覚知放水弁としての機能を兼用しており、消火栓弁開閉レバーの開操作による検出信号や押釦スイッチの開操作による検出信号により図１に示した制御装置が消火栓弁７０を開制御し、ホース５０側に調圧された消火用水が供給されると共に非常覚知ヘッド１４にも供給されて覚知放水が行われる。 Even in the present embodiment, the fire hydrant valve 70 using an electric valve also functions as a conscious discharge valve that discharges water from the emergency conscious head 14, and a detection signal generated by opening the hydrant valve opening / closing lever.
