JP 2005-2111279 A

  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, if you enter the tunnel without noticing it, or if you notice a red light, you will not be able to grasp the situation, so it is assumed that you will enter the tunnel 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.

  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.

It is an object of the present invention to provide an emergency notification facility that can visually notify a traveling driver of an occurrence of an abnormality in a tunnel with a simple facility and can make an emergency stop before the entrance to the tunnel. And

  FIG. 1 is an explanatory view showing an embodiment of an emergency awareness facility according to the present invention in a plane cross section of a tunnel and a road. In FIG. 1, the tunnel 10 indicates the tunnel entrance 12 side, and a two-lane road 14 passes through the tunnel 10. An emergency head 16 is disposed on the exit side of the tunnel entrance 12 across the road 14.

  In addition, the emergency awareness head 16 is disposed at a position away from the emergency awareness head 16 of the tunnel entrance 12 by a predetermined distance L with the road 14 in between. The distance L between the emergency head at the tunnel entrance 12 and the emergency head 16 at the front is set to a distance corresponding to the vehicle braking stop distance determined by the maximum speed of the road 14.

  A head pipe 24 from the valve device 18 is connected to the emergency awareness head 16. A pump facility 20 is provided on the primary side of the valve device 18. The valve device 18 and the pump equipment 20 are controlled by a control device 22.

  The control device 22 operates by detecting the occurrence of an accident such as an accident or a vehicle fire in the tunnel 10, starts the fire pump provided in the pump facility 20, and simultaneously opens the valve device 18. Pressurized sense water is supplied from the head pipe 24 to the emergency sense head 16, and the emergency sense pattern is discharged from the emergency sense head 16 in a direction across the road 14.

  This emergency sense pattern from the emergency sense head 16 notifies the driver of the vehicle traveling on the road 14 that is about to enter the tunnel 10 that an abnormality has occurred, and can make an emergency stop before entering the tunnel 10 And

  The start of operation guide water discharge by the control device 22 is a push button operation of an emergency call device installed in the tunnel 10, a door opening of a fire hydrant device, etc., a fire detection by a fire detector installed in the tunnel, and further not shown. This is performed by a remote control instruction from the monitoring center. Moreover, although the instruction | indication with respect to the control apparatus 22 can be performed by a signal wire | line, you may make it perform by the instruction | indication by radio | wireless besides that.

  Furthermore, a lighting device 26 is installed on the vehicle approaching side of the emergency awareness head 16. The illumination device 26 is turned on by an instruction from the control device 22 when water is discharged from the emergency awareness head 16 at night, and light is applied from the illumination device 26 to the emergency notification pattern discharged from the emergency knowledge head 16. The driver of the vehicle trying to enter the tunnel 10 from the road 14 can surely recognize the emergency awareness pattern.

  FIG. 2 is an explanatory view of the embodiment of FIG. 1 as viewed from the vehicle side trying to enter the tunnel in a water discharge state of the operation guide. In FIG. 2, an emergency head 16 is installed on a pole 15 across a road 14 in front of the tunnel entrance 12, and a turning warning lamp 28 is provided at the tip of the pole 15.

  As shown in FIG. 1, for example, as shown in FIG. 1, an emergency head 16 is disposed across the road 14 by a pole 15 at a position away from the tunnel entrance 12 by a vehicle braking stop distance L. Similarly, a turning warning lamp 28 is provided.

  When an abnormality occurs in the tunnel, a slit-like emergency detection pattern 25 is formed at the entrance of the tunnel 12 so as to block the crossing across the road 14 by discharging pressurized notification water from the emergency detection head 16. It is formed in two places, the front and the vehicle braking stop distance from there.

  For this reason, the driver of the vehicle trying to enter the tunnel in which an abnormality has occurred notices the emergency alert pattern 25 in front and recognizes that something is wrong in the previous tunnel, although the situation is unknown. Emergency stop. If the emergency stop pattern 25 is noticed and an emergency stop is made, there is a vehicle braking stop distance up to the tunnel entrance 12, so that the vehicle can be stopped immediately before entering the tunnel.

  Also, if the driver passes through the emergency awareness pattern 25 without noticing it, the vehicle will pass through the emergency awareness pattern 25 so that water from the emergency awareness head 16 will hit the vehicle strongly. In addition, since the windshield is covered with water, the driver can surely recognize that the emergency sense pattern 25 has been cut through, and further, the emergency sense pattern 25 is formed ahead of it so that an abnormality occurs in the tunnel. Even if it passes through the emergency alert pattern 25 on the near side, it is possible to immediately apply a brake and perform an emergency stop.

  Further, a turning warning lamp 28 is provided at the tip of the pole 15 provided with the emergency awareness head 16 and is turned on when the water is discharged. It is possible to recognize that an abnormality has occurred and thereby recognize the emergency sense pattern 25 reliably and perform an emergency stop. If the pole 15 is a facility that discharges water in the event of a fire, or that it is prohibited to enter the tunnel at the time of water discharge, the driver can recognize the fire in the tunnel more.

  FIG. 3 is an explanatory view showing an embodiment of the valve device 18 of FIG. In FIG. 3, a stop valve 35, a remote start valve (electric valve) 34, a manual start valve 36, a pressure adjustment valve 38, an automatic drain valve 40, and a test water discharge valve 42 are provided for the main valve 30 as control system equipment. ing.

  A water supply pipe 25 is connected to the primary side of the main valve 30, and the water supply pipe 25 is filled with pressurized water for a predetermined pressure. A test water control valve 32 is provided on the secondary side of the main valve 30, and the emergency head 16 is connected to the secondary side via a head pipe 24. As the water for awareness, the water for fire extinguishing used for the fire extinguishing equipment in the tunnel may be used, or the water for snow extinguishing equipment such as roads may be used.

  The test water control valve 32 is normally opened, and is closed when the test operation is performed without actually discharging the water for awareness from the emergency awareness head 16 during inspection. The test water control valve 32 may be a manual valve or an electric valve. However, when the inspection is performed remotely, it is easier to perform the test by using an electric valve.

  The valve 30 is provided with an actuator in which a piston 46 is slidably inserted in a cylinder chamber 44, and the valve body 48 is moved by the movement of the piston 46 to open the valve.

  The opening operation of the valve 30 is performed by the remote start valve 34 during normal monitoring. An electric valve is used as the remote start valve 34, and the remote start valve 34 is opened by sending a start signal based on an abnormality such as a vehicle fire in the tunnel output from the control device 22 of FIG.

  When the remote start valve 34 is opened, the primary side pressure sensing water is supplied to the cylinder chamber 44 via the stop valve 35, the remote start valve 34 and the pressure regulating valve 38, and the piston 46 is stroked to the left side. The body 48 is lifted and released from the valve seat, and water is discharged from the emergency head 16.

  In order to stop water discharge from the emergency awareness head 16, a stop signal is sent from the control device 22 of FIG. When the remote start valve 34 is closed, the supply of pressurized notification water from the primary side to the cylinder chamber 44 via the pressure adjustment valve 38 is stopped.

  When performing an operation test without water discharge from the emergency head 16 by remote control from the control device 22 of FIG. 1, a test water discharge signal is sent from the control device 22 with the test water control valve 32 closed. The remote test water discharge valve 42 is opened, and the activation signal is further sent to open the remote start valve 34 to open the main valve 30. An operation test can be performed.

  When the valve 30 is opened for the operation test, the remote start valve 34 is closed by sending a stop signal from the control device 22 shown in FIG. Since the remote test water discharge valve 42 is open at this time, the main valve 30 can be immediately closed without waiting for the opening operation of the automatic drain valve 40.

  Of course, both the remote start valve 34 and the remote test water discharge valve 42 are closed by the control signal from the center control device 20, and this valve 30 is automatically drained by the automatic drain valve 40, so that the main valve 30 is operated in the same manner as in the normal water discharge operation. You may make it complete | finish test water discharge by closing.

  FIG. 4 is an explanatory view showing another embodiment of the emergency awareness facility according to the present invention. In the embodiment of FIG. 4, the emergency head 16 is provided with the road 14 sandwiched between the tunnel entrance 12 and a distance L corresponding to the vehicle braking stop distance. Are the same, but the emergency head 16 is further arranged at two points between them with the road 14 in between. The other configuration is the same as that of the embodiment of FIG.

  In this way, the emergency head 16 is arranged, for example, at four locations in the road traveling direction while reaching the tunnel entrance 12, and water is discharged from the emergency head 16 in four stages when an abnormality occurs in the tunnel. By forming the emergency awareness pattern, the driver can be sure of the emergency awareness pattern and make an emergency stop before entering the tunnel.

  Further, the installation intervals of the emergency awareness heads 16 in the traveling direction of the road 14 in the embodiment of FIG. 4 may be equal intervals, or the intervals may be increased as the distance from the tunnel increases.

  FIG. 5 is an explanatory view showing another embodiment of the emergency awareness facility according to the present invention. In this embodiment, in addition to the embodiment of FIG. The vehicle detector 50 is installed in each section.

  The vehicle detector 50 detects a vehicle traveling on the road 14 and inputs a vehicle detection signal to the control device 22. When an abnormality occurs in the tunnel and the control device 22 operates the valve device 18 and the pump equipment 20 to form the emergency sense pattern 25 from the emergency sense head 16 as shown in FIG. When the control device 22 discriminates the vehicle detection signal from the detector 50, and knows the water discharge when the stop of the vehicle within the section where the emergency head 16 is installed is detected from the detection signal of the vehicle detector 50. In this case, the vehicle that has stopped in an emergency stops before the tunnel. In this case, the succeeding vehicle notices the preceding vehicle and makes an emergency stop, so that the water discharge from the emergency head 16 is basically stopped. The vehicle detector 50 may be a device that detects a vehicle by observing a change when an ultrasonic wave or a light beam is emitted or by processing an image from a camera.

  This makes it possible to discharge water for a necessary time without enlarging the capacity of the water storage tank provided in the pump facility 20.

  On the other hand, if all the water discharge is stopped when the vehicle stops due to the emergency notification pattern before the tunnel entrance 12, it seems that the abnormality in the tunnel has been resolved, and the vehicle once stopped enters the tunnel. There is a possibility of entering. In order to prevent this, the control device 18 may continue water discharge from the emergency head 16 near the tunnel entrance 12 and stop only water discharge from the other emergency head 16 on the near side. desirable.

  FIG. 6 shows an embodiment of the valve device 18 of FIG. 5, when the vehicle detector 50 detects the stop of the vehicle, the water discharge from the emergency head 16 near the tunnel entrance 12 continues, The apparatus structure at the time of making it stop the water discharge from the emergency awareness head 16 is shown.

  In FIG. 6, the main valve 30, the test water control valve 32, the remote start valve 34, the stop valve 35, the manual start valve 36, the pressure regulating valve 38, the automatic drain valve 40, the remote test water discharge valve 42, the cylinder 44, and the valve body 48. Is the same as the embodiment of FIG. 3, but the head pipe 24 taken out from the secondary side of the test water control valve 32 is branched into a head pipe 24a on the tunnel entrance side and a head pipe 24b on the front side thereof, The emergency head 16 is connected, and the head piping 24a on the tunnel entrance side is directly connected to the emergency head 16, but the emergency head 16 on the front side is connected via a remote opening / closing valve 52. The head pipe 24b is connected.

  For this reason, when the stop of the vehicle with respect to the water discharge section is detected, the main valve 30 continues to be opened as it is, and the remote open / close valve 52 is controlled to be closed by the control device 22, and the emergency head on the near side by the head pipe 24b. 16 is stopped, and the supply of pressurized sensation water is continued only to the head piping 24a for the emergency sensation head 16 on the tunnel entrance side, and the emergency sensation pattern is continuously applied to the tunnel entrance. To form.

  It should be noted that the present invention is not limited to the embodiment of FIG. 6, and when the vehicle is detected, the valve opening degree of the main valve 30 may be reduced to suppress the water discharge amount.

  FIG. 7 is an explanatory view showing another embodiment of the emergency awareness facility according to the present invention, and this embodiment is characterized by taking measures for preventing road surface freezing in winter and the like. In FIG. 7, smoke generating devices 54 are provided corresponding to the emergency heads 16 installed at two locations along the road 14.

  For example, a solid fire extinguisher is accommodated as the smoke generating device 54. The solid fire extinguisher is ignited by a control signal from the control device 22, and an aerosol 56 having a fire extinguishing action is ejected in a direction crossing the road 14 to generate smoke from the aerosol. By this, a warning that an abnormality has occurred in the tunnel is warned to prevent the vehicle from entering.

  That is, in the winter season, if the water for pressurized consciousness is discharged from the emergency conscious head 16 due to abnormalities in the tunnel, the road surface may freeze and lead to a slip accident. When a tunnel abnormality occurs in this state, the control device 22 ignites the smoke generation device 54 instead of operating the valve device 18 and the pump equipment 20 to eject smoke from the aerosol 56 and enters the abnormality in the tunnel. To inform the emergency stop.

  The smoke generating device may be a device similar to a flame emitting cylinder mounted on a vehicle and used in a disaster. The smoke is not limited to the above-described smoke generating device generated by combustion, and may be a device that generates smoke without being burned. It is necessary to emit smoke to such an extent that the driver's view is not obstructed, and it is desirable that the device can control the amount of smoke emitted.

  FIG. 8 is an explanatory view showing an embodiment in which the head is arranged in an arch shape with respect to the road on the tunnel entrance side and the emergency sense pattern is discharged. In FIG. 8, as shown in FIGS. 1 and 2, a frame arch 58 is installed so as to straddle the road before the tunnel entrance, and a plurality of emergency heads are downwardly positioned at positions facing the road surface of the frame arch 58. 16 is arranged. In the frame arch 58, a frame member is constructed in an arch shape, and a head pipe is disposed therein to connect the emergency head 16 to the arch.

  In the present embodiment, when an abnormality such as a fire occurs in the tunnel, a slit-like spray pattern 25a is caused by water discharge from the plurality of emergency heads 16 to the road on the tunnel entrance side. To form.

  FIG. 9 shows another embodiment in which a plurality of emergency heads 16 are arranged on the frame arch 58. In this embodiment, when an abnormality such as a fire occurs in the tunnel, the road on the entrance side of the tunnel is shown. On the other hand, the shower pattern 25 b is formed by discharging the water for awareness from the emergency awareness head 16.

  FIG. 10 shows another embodiment in which a plurality of emergency heads 16 are arranged on the frame arch 58. In this embodiment, when an abnormality such as a fire occurs in the tunnel, the road on the entrance side of the tunnel is shown. On the other hand, the bar-shaped solid pattern 25c is formed by discharging the water for awareness from the emergency awareness head 16.

  FIG. 11 shows another embodiment in which a plurality of emergency heads 16 are arranged on the frame arch 58. In this embodiment, when an abnormality such as a fire occurs in the tunnel, the road on the entrance side of the tunnel is shown. On the other hand, a drip pattern 25d for dropping water droplets is formed by discharging water for awareness from the emergency awareness head 16.

  The water discharge patterns as shown in FIGS. 8 to 11 allow the driver to recognize a fire in the tunnel and suppress the amount of water for awareness. The water discharge timing from the emergency awareness head 16 may be continuously discharged, or may be intermittently discharged to ensure visibility and suppress the water discharge amount.

  FIG. 12 is an explanatory view showing another embodiment of the emergency awareness facility according to the present invention in which a head is arranged in a tunnel.

  In FIG. 12, fire hydrant devices 60 are installed on one side wall in the tunnel 10 through which the road 14 passes, for example, at intervals of 50 meters. The fire hydrant device 60 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 60 can be drawn out so that the water can be discharged in a range of 25 m on the left and right in the tunnel traveling direction.

  The fire hydrant device 60 is provided with a transmitter that operates in the event of a fire and outputs a fire detection signal. A fire indicator lamp indicating the location of the transmitter is displayed near the transmitter, and a response display for the push button operation of the transmitter. A response indicator light is provided.

  In the present embodiment, the valve devices 18 are installed at regular intervals, for example, 100 meter intervals, which are every other fire hydrant device 60 installed in the tunnel 10, and the road 14 in the tunnel is routed from the valve device 18. A head pipe 24 is arranged in an arch shape along the tunnel ceiling surface that traverses, and a plurality of emergency heads 16 are arranged facing and connected downward to the road surface.

  The emergency awareness head 16 connected to the head pipe 24 forms the patterns shown in FIGS. 8 to 11 in a direction crossing the road in the tunnel by discharging the awareness water. The transmitter and response indicator lamp provided in the fire hydrant device 60 are connected to the control device 22 by signal lines, and the valve device 18 is also connected to the control device 22 by signal lines.

  For example, the control device 22 receives a fire detection signal by operating a push button of a transmitter provided in the fire hydrant device 60, or a pump start signal when the fire hydrant valve opening / closing lever is opened after the hydrant door is opened and the hose is pulled out. Occasionally, the valve device 18 corresponding to the section including the fire hydrant device 60 that transmitted the signal and the section in front of the section is opened to open the valve, and the pump facility 2 is activated to supply the water for awareness to the water supply pipe 61. Then, the emergency sense pattern 16 is discharged in the direction across the tunnel from the emergency sense head 16 connected to the head pipe 24 from the valve device 18 which is opened, and an abnormality is caused to the driver of the vehicle entering the tunnel. Let me know and make an emergency stop.

  For example, if a vehicle fire occurs in the section L2, the driver opens the door of the nearby fire hydrant device 60, pulls out the hose with a nozzle, and opens the fire hydrant valve opening / closing lever. When the hydrant valve opening / closing lever is opened, a pump activation signal is sent to the pump facility 20 via the control device 22 to activate the fire pump and supply pressurized water for water supply to the water supply pipe 62 and discharge it from the nozzle.

  At this time, the control device 22 recognizes the occurrence of an abnormality from the pump activation signal from the fire hydrant device 60, and sends the activation signal to the valve device 18 installed in the section L1 where the fire has occurred and the section L2 in front of it to open the valve. At this time, the pressurized awareness water supplied from the pump facility 20 is sent from the valve device 18 to the head pipe 24, and the emergency sense pattern is formed in the direction of the tunnel cross section by the water discharge from the emergency sense head 16, and the fire occurrence section It is possible to warn the driver of the vehicle entering L2 that an abnormality has occurred in the front tunnel, and to reliably stop braking before the location of the fire.

  FIG. 13 is an explanatory view showing oblique water discharge by a rod-like pattern in the embodiment in which the emergency head is arranged in the tunnel as shown in FIG. 12, FIG. 13 (A) is a cross section of the tunnel, FIG. ) Shows the tunnel plane.

  In FIG. 13, the emergency awareness head 16 discharges the rod-shaped pattern 62 in order to minimize the amount of water discharged for awareness. In this embodiment, the emergency awareness head 16 is shown in the tunnel cross section of FIG. In this way, water is discharged obliquely downward from the emergency head 16 installed in the upper part of the tunnel 10 and is also discharged obliquely with respect to the traveling direction as shown in the tunnel plane of FIG.

  By such slanted water discharge of the bar-shaped pattern 62, a vehicle traveling in the tunnel recognizes the occurrence of an abnormal situation by seeing water discharged by the bar-shaped pattern 62 from diagonally upward in the traveling direction, and the vehicle body without being aware of the water discharge By receiving water discharge so that it crosses diagonally, it is possible to recognize the occurrence of an abnormal situation.

  In addition, a smoke layer 64 is formed in the upper part of the tunnel due to a fire. However, since the emergency head 16 discharges a single bar-shaped pattern 62, the smoke layer 64 is disturbed by the water discharge, and the smoke spreads throughout the tunnel. Can be prevented.
