Description

TECHNICAL FIELD The present invention relates to a disaster prevention system and a partition device for a tunnel that suppresses the fire while securing an evacuation environment against a fire in the tunnel.

Conventionally, as shown in FIG. 14, the inside of tunnels dedicated to automobiles is provided with water spray equipment, and when a fire detector 200 detects a fire, the automatic valve device 202 of the water discharge section corresponding to the location of the fire is activated. Fire extinguishing water is sprayed from a water spray head 204 provided on the tunnel ceiling side to suppress and prevent damage to the tunnel frame, etc. due to fire, and to suppress fire extinguishing.

In addition, fire hydrant devices 208 are installed on the tunnel side wall along the observer passage 206 at intervals of, for example, 50 meters. The fire can be extinguished by directing the nozzle toward the fire and spraying water. Furthermore, a lighting device 210 and a ventilation device 212 using a jet fan are installed in the tunnel.

However, once a fire breaks out in such a tunnel disaster prevention system, the inside of the tunnel is filled with smoke. It is difficult to evacuate through an emergency exit, and there is still the possibility that it will not be possible to evacuate safely.

In order to solve this problem, multiple head rows are arranged in the direction across the road on the ceiling or side wall of the tunnel. ) are formed to form partitions, and in addition to suppressing fires, fire and smoke prevention equipment has been proposed that suppresses the spread of smoke caused by fires and enables safe evacuation (Patent Documents 1 and 2).

In addition, a curtain unwinding device is arranged in the longitudinal direction of the tunnel, and in the event of a fire, a fire curtain is lowered from the curtain unwinding device toward the road to form an evacuation space by separating the guard passage from the road side, making it possible to evacuate safely. There has also been proposed a facility to do so (Patent Document 3).

JP-A-2004-313753 Japanese Unexamined Patent Application Publication No. 2013-202102 JP-A-2002-035147

However, in conventional disaster prevention equipment for tunnels that partition the fire area by forming a water curtain, the tunnel space cannot be partitioned as well as the fire curtain, so if the scale of the fire becomes large, water will not flow. Smoke may spread through gaps in the curtains, making it difficult to sustain a safe evacuation environment.

In addition, conventional disaster prevention equipment that separates the guard passage and the road side with a fireproof curtain can secure a safe evacuation route in the event of a fire, but if the scale of the fire increases, it will continue to receive the heat and flames of the fire directly. The fire curtain may burn and break, and smoke may flow into the evacuation route from the broken point, causing the evacuation route to be lost.

The present invention comprises a first partitioning means arranged along the longitudinal direction of the tunnel and partitioning the inner space of the tunnel into a fire-side region including at least the fire source position and a non-fire-side region in the event of a fire; Since the second partition means is provided for partitioning the gap area generated when the partition means divides the area on the fire side and the area on the non-fire side, in the event of a fire, the space inside the tunnel is separated from the area on the fire side in the lane direction. It is divided into a non-fire side area and a non-fire side area (one side of the tunnel space in the lane direction) to block smoke, heat, and fire, and to ensure a safe evacuation environment.

(Effect of Fire Extinguishing Means)
In addition, since the fire-extinguishing means for spraying the fire-extinguishing agent to the fire-side area is provided in a state where the fire-side area and the non-fire area are partitioned by the first partition means and the second partition means, While ensuring a safe evacuation environment by blocking smoke, heat, and flames in the area, spraying fire-extinguishing agent in the area on the fire side to extinguish the fire, suppress the fire, and prevent water damage. allow it to be suppressed.

Here, fire extinguishing suppression is a combination of the concept of extinguishing a fire and another concept of suppressing a fire. For example, extinguishing a fire is a concept of extinguishing combustion, and suppressing a fire is a concept of suppressing the spread of fire. Needless to say, this includes the case of either one of them.

(Effect of partition)
Further, in the event of a fire, the first partition means and the second partition means partition at least two locations on the upstream side and the downstream side of the area on the fire side to form a partition section including the fire source position in the space inside the tunnel. Therefore, it is possible to form a closed area (compartment) that includes the fire source position in the space inside the tunnel by forming a partition section, and for the non-fire areas on both sides of the partition section in the longitudinal direction of the tunnel A safe evacuation environment can be ensured by blocking smoke, heat and flame.

To quickly and surely extinguish a fire and suppress water damage by spraying a fire extinguishing agent in a closed partition and an area including a fire source position in the partition while securing the environment. enable

(Effect of deployment of partition sheet)
In addition, the first partition means deploys the partition sheet in the event of a fire to partition the area on the fire side and the area on the non-fire side, and the second partition means deploys the partition sheet in the event of a fire to create the first partition. Since the gap area generated by the deployment of the partition sheet of the means is partitioned, the area on the fire side and the area on the non-fire side in the tunnel space can be easily and reliably partitioned and divided by the deployment of the partition sheet. A closed partition can be easily and reliably formed by partitioning the area on the fire side at two points, the upstream side and the downstream side in the lane direction.

(Effect of turning partition means)
The first partition means has a fixed end and a movable end, and the initial positions of the fixed end and the movable end are arranged in the vicinity of the guard passage so that the initial positions of the fixed end and the movable end are along the longitudinal direction of the tunnel. In the event of a fire, the movable end is rotated around the fixed end to a predetermined turning target position facing the fixed end in the tunnel width direction, and in the state of turning to the turning target position, the partition sheet is deployed. Since the space inside the tunnel is divided into the area on the fire side and the area on the non-fire side, the first partitioning means functions as a revolving crane, and in the event of a fire, it moves from the initial position along the longitudinal direction of the tunnel to the width direction of the tunnel. By turning to the turn target position and deploying the partition sheet, the space inside the tunnel can be divided into a fire side area and a non-fire side area, and the two areas can be separated easily and reliably. A closed partition section can be easily and reliably formed by deploying and partitioning the partition sheet at two locations, upstream and downstream in the lane direction, of the existing area on the fire side.

In addition, since the body means is in the normal state (initial state) at the initial position substantially directly above the guard passage along the longitudinal direction of the tunnel, it does not hinder the flow of vehicles.

(Effect of partition sheet)
In addition, since the partition sheet uses a cloth-like material having fireproof, fire-resistant, heat-resistant, heat-insulating, flame-blocking, or smoke-blocking properties, the cloth-like partition sheet is flexible. By measuring the dimensions, the occurrence of gaps can be suppressed, and the degree of reduction in fire resistance, fire resistance, heat resistance, heat shielding, flame shielding, smoke shielding, etc. is improved. It also facilitates movement (evacuation) between partitioned areas.

(Effect of spraying coolant)
In addition, since a coolant spraying means for spraying the coolant on the partition sheet is provided, for example, the coolant is sprayed on the outside, the inside, or both the outside and the inside of the partition sheet, the inside of the tunnel space is the area on the fire side. and a partition sheet that divides the area on the non-fire side or a partition sheet that divides the area on the fire side at two points, upstream and downstream in the lane direction, to form a partition section. The fire resistance, fire resistance, heat resistance, heat shielding, flame shielding and smoke shielding properties of the sheet can be further enhanced. Here, the sheet surface in the direction toward the fire source position is defined as the inner side, and the sheet surface in the opposite direction is defined as the outer side.

(Second invention: Effect of turning type partition device)
Another aspect of the present invention is a partitioning device for partitioning a space inside a tunnel, which has a fixed end and a movable end, and the initial positions of the fixed end and the movable end are located in the vicinity of the guard passage along the longitudinal direction of the tunnel. Normally, the movable end is held at the initial position, and in the event of a fire, the movable end is turned around the fixed end to a predetermined turn target position facing the tunnel width direction, and in a state where the turn target position is reached, The space in the tunnel is partitioned into a fire side area including at least the fire source position and a non-fire side area by deploying the partition sheet, and a coolant spraying means for spraying the coolant on the partition sheet is provided. Therefore, the same effect as that shown in the turning type first partitioning means in the first invention can be obtained.

(Effect of opposing arrangement of partition devices)
In addition, since the partition devices are arranged at predetermined positions on both sides of the inner wall surface of the tunnel facing each other in the tunnel width direction, the length of each partition device arranged facing each other is, for example, about half the width of the road, and the number of installations is reduced. Although the size and weight can be reduced, the installation work can be simplified and the total equipment cost can be reduced.

(Tunnel entrance closed in case of fire)
In addition, in the event of an emergency, including a fire, the partition sheet is deployed at a predetermined position on the tunnel entrance side to close the tunnel entrance, preventing vehicles from entering the tunnel in the event of an emergency such as a fire or vehicle accident. To prevent the occurrence of a secondary disaster by surely blocking it.

[Disaster prevention equipment]
FIG. 1 is an explanatory diagram showing an embodiment of disaster prevention equipment installed in a tunnel, and FIG. 2 is an explanatory diagram showing a state in which a partition sheet of the disaster prevention equipment is deployed to partition the space inside the tunnel in the event of a fire. Note that the partition sheet in FIG. 2 is shown in a transparent state so that the inside of the tunnel can be seen. 14, the tunnel 10 is provided with a fire detector, a water spray head, a fire hydrant device, a lighting device, a ventilation device, etc., except for the fire detector 92 and the fire hydrant device 24. Illustration is omitted.

[Basic concept of the embodiment]
The basic concept of the disaster prevention equipment for a tunnel according to this embodiment is that for a tunnel 10 having a road 12. For example, a swivel partition device 16 functioning as a first partition means has a fixed end 16b as an axis. The other end is a movable end 16c, and the initial positions of the fixed end 16b and the movable end 16c are aligned with the longitudinal direction of the tunnel, that is, the longitudinal direction of the main body and the longitudinal direction of the tunnel are aligned with each other. 1, and in the event of a fire, as shown in FIG. The partition sheet 16a is unfolded in a state in which it is turned to a predetermined turning target position (locking position of the stopper 17) in the tunnel width direction substantially orthogonal to , that is, in a state in which the main body is turned so that the longitudinal direction of the main body and the tunnel width direction are aligned. and divides the tunnel longitudinally into a fire side region including at least a position region where the fire source 100 exists (hereinafter referred to as “fire source position”) and a non-fire side region, and further functions as a second partition means. The ceiling partition device 18, the guard passage partition device 20 and the side wall partition device 22 deploy the partition sheets 18a, 20a and 22a. It is to partition the gap area that occurs when partitioning into the side area and the side area.

As a result, in the event of a fire, the space inside the tunnel is divided in the longitudinal direction of the tunnel into a fire-side area and a non-fire area, and the non-fire area of the tunnel space is shielded from smoke, heat, and flames. can ensure a safe evacuation environment.

The partition sheets 16a, 18a, 20a, and 22a are deployed to divide the space in the tunnel into a fire side area including the fire source position and a non-fire side area. Fire extinguishing water, for example, is sprayed from the extinguishing head 26 as an extinguishing medium. As a result, fire can be extinguished by spraying fire extinguishing water in the area on the fire side, while ensuring a safe evacuation environment by blocking smoke, heat, and flames in the area on the non-fire side. It also reduces water damage in areas not on the fire side.

Here, the longitudinal direction of the tunnel is parallel to the lane direction of the road 12, the tunnel entrance side in the lane direction is defined as the upstream or upstream side, and the tunnel exit side is defined as the downstream or downstream side.

In addition, in the event of a fire, the partition sheets 16a, 18a, 20a, and 22a are deployed and partitioned at at least two locations on the upstream side and downstream side of the area on the fire side including the fire source position, so that the fire source position is located in the space inside the tunnel. It forms a partition compartment 15 containing. By forming the partition 15 in this way, a closed area (section) including the fire source position can be formed in the space inside the tunnel. A safe evacuation environment can be ensured by blocking smoke, heat and flame in the non-side area.

In addition, fire extinguishing water is sprayed from the fire extinguishing head 16 into the partition section 15, thereby blocking smoke and heat from the non-fire areas on both sides of the partition section 15 in the longitudinal direction (lane direction) of the tunnel. And, while ensuring a safe evacuation environment by flame shielding, fire extinguishing water is sprayed in the partition section 15 including the position where the closed fire source 100 exists, so as to suppress the fire quickly and reliably. can be done. In addition, since the formation of the partition 15 suppresses the dissipation of the extinguishing agent, water damage to the outside of the partition 15 is prevented, and the effect of suppressing fire extinguishing within the partition is enhanced. A detailed description will be given below.

[Overview of Tunnel Disaster Prevention Equipment]
As shown in FIG. 1, the disaster prevention equipment of the present embodiment is provided with an observer passage 14 that is also used during evacuation along one shoulder of a road 12 on which vehicles pass in a tunnel 10. The observer passage 14 A turn functioning as a first partition means along the lane direction of the road 12, that is, along the longitudinal direction of the tunnel, on the inner wall surface of the tunnel in the vicinity directly above, for example, the vicinity directly above the substantially vertical slope 14a on the side of the road 12 in the guard passage 14. The mold partitioning devices 16 are arranged at predetermined intervals, and at this time, the rotating type partitioning device 16 holds the partition sheet in a rolled state.

Here, the turning type partition device 16 has one end as a fixed end 16b and a main body that is pivotally supported on the inner wall surface of the tunnel, and the other end as a movable end 16c. The direction, that is, the longitudinal direction of the main body of the turning type deploying device 16 shown in the drawing, is arranged so as to be substantially parallel to the longitudinal direction of the tunnel (lane direction). The position where the movable end 16c is positioned at this time is the initial position.

On the other hand, in the event of a fire, as shown in FIG. 2, the fire source 100 is positioned at two locations upstream and downstream of the fire side area (area where the fire detector 92 detects the fire) including the fire source position where the fire source 100 exists. The swivel partitioning device 16 swivels the movable end 16c about the fixed end 16b to a predetermined swivel target position, for example, the position of a stopper 17 installed on the tunnel side wall substantially facing the fixed end 16c in the tunnel width direction. For this reason, the turning target position of the movable end 16c of the turning type partition device 16 is, for example, a position in the vicinity of the wall surface facing the position of the fixed end 16b across the road 12 in the tunnel width direction.

Subsequently, the revolving partitioning device 16, which has turned to the turning target position, releases the holding of the partitioning sheet wound in a roll and drops the lower side of the sheet to deploy the partitioning sheet 16a. A predetermined area including the source position is partitioned, and at least the area on the fire side including the fire source position in the tunnel space is partitioned at two locations, upstream and downstream, to form a partition section 15 .

When the partition sheet 16a is unfolded to form the partition section 15 in a state where the rotary partition device 16 is rotated, a gap area is generated on both sides and an upper portion (ceiling side) of the partition sheet 16a in the tunnel width direction. In order to partition this gap area, as shown in FIG. By arranging the partition device 22 and expanding the respective partition sheets 18a, 20a and 22a as shown in FIG. In this manner, the ceiling partition 18, guard passage partition 20, and side wall partition 22 each function as second partition means.

Here, in the case of the illustrated two-lane tunnel 10, the width of the tunnel is, for example, about 12 meters. It will be about 10 meters long, excluding the passage width. Also, the installation interval of the turning type partition devices 16 in the longitudinal direction of the tunnel is, for example, 25 meters. It should be noted that the installation interval of the rotating partition device 16 in the longitudinal direction of the tunnel may be appropriately set as necessary within a range exceeding the entire length of the rotating partition device 16 .

Alternatively, only one turning type partition device 16 may be installed in the inner space of the tunnel. For example, when the length of the tunnel is short, only one turn-type partition device 16 is installed, for example, near the center in the longitudinal direction of the tunnel. A partition device 22 is installed to partition the space in the tunnel into the upstream side and the downstream side in the event of a fire.

In addition, fire detectors 25 are installed at predetermined intervals, for example, 25 m intervals along the side wall surface of the tunnel on the guard passage 14 side in the longitudinal direction. Equipped with a detection unit, so that the detection area with other fire detectors arranged adjacently overlaps in a mutually complementary manner, that is, the detection area on the upstream side of one fire detector 92 and the detection area on the upstream side of this It is arranged continuously so that the detection area on the downstream side of the adjacent fire detector 92 overlaps, and detects the fire by observing the infrared rays from the fire flame occurring in its own monitoring area (detection area). .

In this embodiment, the installation interval of the revolving partition device 16 and the installation interval of the fire detectors 92 are the same 25 meters, and the fire detection area by the fire detectors 92 corresponds to the area on the fire side shown in FIG. concept.

[Rotating partition device]
FIG. 3 is an explanatory view showing a state of the swivel partition device in which the movable end is swiveled to the swivel target position before the sheet is unfolded, and FIG. 4 is an explanatory view showing an embodiment of the swivel partition device. ) shows the normal state, FIG. 4(B) shows the developed state of the partition sheet, and FIG. 4(C) shows a plan view from below.

(Structure of rotating partition device)
As shown in FIG. 3, the rotary partition device 16 is composed of a device including a main body 28 and a partition sheet 16a. The main body 28 operates as a so-called slewing crane, and the movable end 16c is rotatable around the fixed end 16b by a slewing drive section 30 installed on the inner wall surface of the tunnel. The movable end 16c is turned from the initial position to the turning target position, which is the wall surface facing the position of the fixed end 16b across the road 12, so as to be substantially parallel to the direction.

Here, the rotary actuator 30 that pivotally supports the fixed end 16b of the main body 28 uses, for example, a hydraulically driven rotary actuator or the like. Alternatively, an electric rotary actuator may be used, or a turning drive mechanism by winding and unwinding a wire rope may be used.

As shown in FIG. 4A, a housing 32 is fixed to the lower part of a main body 28 that is turned by a turning driving unit 30 fixed to the inner wall surface of the tunnel by a fixing part 31, and one end of the partition sheet 16a is attached to the housing 32. The partition sheet 16a is fixed by a sheet fixing portion 35, and the partition sheet 16a is held in a suspended state at a plurality of positions by a sheet holding member 34 using a wire or a rope on the lower side of the housing 32 in a rolled state. .

The partition sheet 16a is a cloth-like body having fire resistance, fire resistance, or heat resistance. As the partition sheet 16a, even if it is 1200° C. or less, it is sufficient if it has a heat resistance performance of, for example, several hundred degrees or more. In addition, the partition sheet 16a has properties such as heat shielding, flame shielding, and smoke shielding properties.

A sheet holding member 34 using a wire or rope has one end fixed to the housing 32 and the other end passing through the bottom of the partition sheet 16a wound in a roll shape so as to be attachable and detachable to a sheet unfolding section 36 provided in the housing 32. held in place and normally capped. The sheet unfolding section 36 releases the holding of the sheet holding member 34 by, for example, energizing a solenoid in response to a control signal from the disaster prevention receiving panel.

When the sheet unfolding portion 36 is actuated by a control signal from the disaster prevention receiving panel, the turning type partition device 16 releases one end of the sheet holding member 34, and as shown in FIG. While the upper side) is fixed to the housing 32, the other side (lower side) on the opposite side falls due to its own weight and expands in the vertical direction. A predetermined weight member may be provided on the lower side of the partition sheet 16a. By doing so, the lower side of the partition sheet 16a can be dropped, and the stability after the partition sheet 16a is deployed can be assisted. .

Here, the vertical length of the partition sheet 16a developed as shown in FIG. This is because even if there is a vehicle or the like on the road 12, the slackness of the partition sheet 16a prevents the gap from forming when the vehicle is dropped and deployed.

The rotary partitioning device 16 may have a structure in which the partitioning sheet 16a is wound around a rotating shaft and the partitioning sheet 16a is unfolded by releasing the latch of the rotating shaft, or a structure in which the partitioning sheet 16a is unwound and rewound by a motor drive. good. Alternatively, the partition sheet 16a of the revolving partition device 16 may be held in a bellows-folded state and unfolded after being unfolded.

(coolant spray head)
As shown in FIG. 4, the swivel partitioning device 16 is provided with coolant spraying heads 38 serving as coolant spraying means on pipes taken out from both sides of the housing 32 . A water supply pipe 42 passing through the housing 32 is connected to the cooling agent sprinkling head 38 via an on-off valve 40, and a partition sheet developed as shown in FIG. Fire extinguishing water (cooling water), for example, is sprayed as a cooling agent on the sheet surface of 16a.

In addition, the partition sheet 16a may or may not be coated with a resin or the like on the surface of the fabric texture. , the sheet surface of the spread partition sheet 16a is wetted, the partition sheet 16a having a weave structure of cloth is impregnated with the sprinkled cooling water, and flows down along the sheet surface.

Such impregnation of the cooling water and flowing down along the sheet surface closes the gaps in the texture of the partition sheet 16a, improves the smoke-blocking property, and suppresses diffusion of smoke to the outside of the partition sheet 16a. . Moreover, the partition sheet 16a is cooled, and the flame-shielding and heat-shielding properties are enhanced. Moreover, damage to the partition sheet 16a due to heat is suppressed.

It should be noted that cooling water may be sprayed on the spread partition sheet 16a either inside or outside the sheet surface, or by spraying cooling water on both the inside and outside of the sheet surface. Also good. Here, the sheet surface facing the area on the fire side is defined as the inner side, and the sheet surface on the opposite side is defined as the outer side.

In this embodiment, as shown in FIG. 3, a cooling agent spraying head 38 is provided on the swivel partition device 16 so that the sheet surface of the partition sheet 18a developed by the ceiling partition device 18 is also cooled. Fire extinguishing water (cooling water) can be sprayed as an agent.

In addition, on both sides of the swivel partition device 16, a cooling agent spraying head 38 is provided obliquely downward toward the side wall of the tunnel. Fire extinguishing water (coolant) can be sprayed as a coolant on the sheet surface of the

[Ceiling partition device]
5A and 5B are explanatory diagrams showing an embodiment of the ceiling partition device, FIG. 5A showing a sheet holding state, and FIG. 5B showing a sheet unfolding state.

As shown in FIG. 5, the ceiling partition device 18 is arranged at a predetermined position along the tunnel width direction orthogonal to the tunnel longitudinal direction on the tunnel ceiling side wall surface. The ceiling partition device 18 is provided separately on both sides in the tunnel width direction (left and right sides in the figure) with respect to the ceiling center line aa', and the partition sheet 18a is deployed using a fan structure. FIG. 5 shows the structure of the ceiling partition device 18 provided on the observer passage side (left side in the figure) of the ceiling center line aa'.

Taking the observer passage side (left side in the drawing) as an example, the ceiling partition device 18 fixes the storage case 44 that opens downward along the wall surface of the tunnel ceiling, and the lower left end of the storage case 44 in the drawing. One ends of a plurality of bone arms 46, for example three bone arms 46, are rotatably supported on a shaft 48. As shown in FIG. The bone arm 46 has substantially the same curved shape as the wall arch on the ceiling side, and is fixed to the partition sheet 18a as shown in the developed state of FIG. 5(B).

As a result, when the bone arms 46 are rotated upward about the shafts 48 to store the bone arms 46 in the storage case 44, the partition sheet 18a is stored in the storage case 44 while being folded along the creases 52 indicated by dotted lines between the bone arms 46. can.

The partition sheet 18a folded in the storage case 44 is held by a latch pin 50 (sheet holding means). The latch pin 50 is provided in a solenoid drive section (not shown) arranged on one of the outer surfaces of the storage case 44 so as to be retractable.

As shown in FIG. 5(A), a latch pin 50 is positioned below the distal end of the bone arm 46 of the partition sheet 18a folded into the storage case 44, and this latch allows the partition sheet 18a to be folded into the storage case 44. holding on.

The latch pin 50 is pulled into the solenoid driving portion by driving the solenoid (sheet unfolding means or sheet holding release means) by a control signal from the disaster prevention receiver board, thereby releasing the holding of the tip of the bone arm 46 and allowing the bone arm 46 to return to its own weight.
