Description
METHOD AND SYSTEM FOR EXTINGUISHING FIRE IN A TUNNEL
DESCRIPTION
The present invention refers to a method and a system for extinguishing fire in a tunnel.
The problem regarding extinguishing fire in tunnels is becoming more and more concerning and contemporary given the great number of road and railway tunnels present on one hand and the expansion of an ever-growing safety demand on the other.
In the order of priorities to be taken into account when it comes to a system for extinguishing fire in a tunnel, the first issue regards the efficiency of the extinguishing method, as well as the safety of the people involved in the fire extinguishing operations.
Known are extinguishing systems comprising fixed extinguishing stations distributed over the entire area of the tunnel, made up of spray nozzles along a section of the tunnel.
Required in such systems, is an efficient fire detection system and also capable of identifying the source location quite accurately, in such a manner that the amount of water required by this system can be materially available and transportable.
In any case, the amount of water required is very high and the system is not capable of concentrating the extinguishing action in the specific area affected by the fire but requires distribution of the water on a more extensive area.
Furthermore, as a matter of fact, such systems imply high
implementation and maintenance costs due to the fact that they involve the entire extension of the tunnel.
Thus, the technical task subject of the present invention is that of providing a method and system for extinguishing fire in a tunnel capable of overcoming the technical drawbacks observed in the known art .
In the scope of this technical task one of the objectives of the invention is that of providing a method and a system for extinguishing fire in a tunnel capable of ensuring high efficiency, total safety and reasonable costs or costs compatible with the performances.
The technical task, alongside these and other objectives, according to the present invention are attained by providing a method and system for extinguishing fire in a tunnel according to the independent claims provided hereinafter.
Furthermore, other characteristics of the present invention are outlined by the remaining claims.
The system for extinguishing fires in a tunnel according to the invention maximises the efficiency but without reducing the cooling capacities in any way, it is reliable, safe and efficient, and its overall cost is wholly justified by the performances provided.
Maintenance activities can be standardised and concentrated on the few specific and easily interchangeable components.
The system is also physically applicable in already existing
tunnels, which are thus not closed for the entire period of installation operations. In particular, the system can be easily- installed reducing the local activities and the space occupied in the tunnel, which is particularly important for a tunnel still being used.
The system can be used without distinction both for road/highway tunnels and railway/subway tunnels.
Advantageously, the system can be used beyond fire safety requirements, extending its purposes to monitoring and maintenance activities even during normal use conditions of the tunnel (washing and environmental restoration operations, monitoring operations thanks to the cameras mounted on the moveable units which can be moved when required by means of a remote control to any monitoring point, constant monitoring of the level of pollution in the tunnel) to guarantee, alongside the considerable inexpensiveness, also the possibility of cost recovery within a short period of time.
Furthermore, the system can be used for an unlimited period of time, it can also be operated automatically without requiring direct interventions by the personnel, it can provide for the possibility of direct intervention by an operator at a remote station, who can optimising its performance from a safe location.
Lastly, the system can perform automatic and constant self- diagnosis regarding its state, both in stand-by and in operating
conditions .
Further characteristics and advantages of the invention shall be clearer from the description of a preferred but not exclusive implementation of the method and system for extinguishing fire in a tunnel according to the finding, illustrated for exemplifying but non-limiting purposes in the attached drawings, wherein:
Figure Ia schematically shows a tunnel provided with an extinguishing system under normal operating conditions with the extinguishing unit idle;
Figure Ib schematically shows the tunnel of figure Ia with the extinguishing units at operating position;
Figure 2 shows a front view of a section of the system in proximity to the moveable extinguishing unit; and
Figure 3 shows a cross-section of the system of figure 1.
Referring to the abovementioned drawings, shown is a system for extinguishing fire in a tunnel indicated in its entirety with reference number 1.
The system comprises a fixed structure 5 having a plurality of fixed reference stations 2 arranged along the entire route of the tunnel, a series of moveable extinguishing units 3 capable of moving using such fixed structure as a track, and a remote control station 4.
The fixed structure 5 comprises an equipped special track 6, along which the reference stations 2 adapted to observe and
monitor for possible fires in the tunnel are provided at regular intervals (for example 40 metres approximately) .
Furthermore, the system 1 is provided with a fire detection system.
The fire detection system comprises a first detection system based on infrared flame detectors mounted on the fixed reference stations 2. Such flame detectors 7 are capable of identifying, without setting off false alarms, the physical quantities generated by the transiting vehicles under normal operation conditions and operating safely also detecting fire in the presence of extremely dense smoke. Additionally, the infrared radiation is optimally reflected also by walls provided with irregular surfaces.
In addition, the fire detection system comprises a second fire detection system based on a heat-sensitive cable 8 installed along the entire extension of the fixed structure 5. The heat-sensitive cable 8 is calibrated to a suitable intervention temperature (for example 1050C) and it is capable of signalling fire according to the desired resolution (for example with a resolution less than 10 linear metres) .
It is provided for that the heat-sensitive cable 8 be divided into physically separated areas, each corresponding to a preset linear extension (for example 10 metres approximately) . This solution is preferred to providing for a single extremely long heat-sensitive cable, in which the section in alarm is
identified by means of resistivity measurements, given that it guarantees much higher reliability under operating conditions in that, in case of a malfunction, only one section shall be inoperative.
In such manner, a double fire detection system in a tunnel is made, based on two different physical principles and both are capable of operating without restrictions in the special conditions which arise from the presence of fire in the tunnel, providing a safe and certain identification of the source or the sources of fire present .
The fixed stations 2 are connected to the remote control station 4.
In particular, integrated in the fixed structure are a power supply line 9 and a signal delivery line 10 (for example of the optical fibre type) which connect the fixed reference stations 2 to the remote control station 4.
The fixed reference stations 2 are connected to the remote control station 4 in a redundant manner even in radio frequency.
The power supply line 9 is used in the tunnel for supplying electric power to the fixed reference stations 2 and to the moveable extinguishing units 3 when the latter occupy the fixed reference stations 2.
In particular, at each reference station 2 installed is a microprocessor unit capable of reading signals regarding the section of the tunnel associated to it and delivering the
resulting data to the remote control station 4.
The detection system is directly or indirectly connected (through the fixed reference stations 2) to the remote control station 4.
Analogously, the moveable extinguishing units 3 are directly or indirectly connected (through the fixed reference stations 2) to the remote control station 4.
Each moveable extinguishing unit 3 is preferably provided with an independent radio system for a bidirectional delivery of the monitoring information (for example, the current position and speed) .
Though capable of operating the system in a centralised and completely autonomous manner, the remote control station 4 can be interfaced with one or more remote modules (not shown) installed at tunnel control centres (modules which allow both monitoring the entire process and intervening manually during any of the steps) .
The fixed structure 5 comprises a supply line 11 for fire- extinguishing product, for example in form of water and/or foam.
In particular, the fire extinguishing product supply line 11 can be made up of a high pressure pipe (for example at 10 bars) for supplying water or a fire-extinguishing foam mixture continuously generated from one (or more) special mixing and pumping stations.
Each moveable extinguishing unit 3 comprises a small carriage
12 provided both with an independent electric motor 13 and high efficiency batteries 14 for supplying the energy required to move the carriage. Furthermore, the moveable extinguishing unit is provided with a water- foam monitor 15 with an electric remote control, and at least one high sensitivity camera 16 and an infrared camera 17 which allow monitoring the event from the remote control station 4. The carriage can be guided along the entire fixed structure at a variable speed before being stopped at any one of the fixed reference stations 2 present in the tunnel .
Upon being stopped at the station 2, the moveable extinguishing unit 3 is connected automatically to the fire- extinguishing product supply line 11 through a special coupling system, making the monitor 15 operative and ready to use. The connection of the moveable extinguishing unit 3 to the power supply line 9 is performed automatically as an extension of the automatic coupling system to the fire-extinguishing product line.
The coupling system (not shown) provides for a female part and a male part .
The female part is fixed by means of a plate to the fixed structure of the tunnel while the male part is provided on board the moveable extinguishing unit 3.
The female part provides for a central hose fitting suitable for hydraulic connection and having on its two oppositely
positioned sides two electric connections in turn provided with two adjacent seats adapted to receive the centring pins when connecting with the male part.
The male part has a hydraulic connection hose fitting with the central hose fitting of the female part being positioned in such a manner to associate with the latter by means of a lever, such as for example a pantograph system, moved by moving means such as for example electromagnetic or mechanical systems with a worm screw or electromagnetic systems such as for example stepper motors.
Once the moveable extinguishing unit 3 stops in front of the female part the lever movement system is operated and the two centring pins, by penetrating into the respective seats, allow the male hose fitting to connect with the female hose fitting providing a liquid seal.
The electric connection is also performed simultaneously.
Provided inside the female hose fitting is a damped conical oscillating system capable of adjusting any movements that might occur between the male part and the female part which could lead to leakages.
In this manner, the liquid seal is guaranteed even though a perfect complanarity and a perfect concentricity of the male hose fitting and the female hose fitting are not provided.
Under normal operating conditions (idle for the extinguishing system) a preset number of moveable extinguishing units 3
(variable depending on the length of the tunnel) are arranged along the fixed structure at regular intervals. Illustrated in the drawings are four subsequent moveable extinguishing units 3 indicated with reference n-1, n, n+1, n+2 indicating the reciprocal arrangement of one with respect to the other.
In figure Ia the extinguishing units 3 are present idle at specific fixed stations 2.
In case of a fire alarm the remote control station 4 immediately operates the two moveable extinguishing units 3 (n) , 3 (n+1) present right upstream and downstream of the signalled location of fire 18. Such moveable extinguishing units 3 (n) , 3 (n+1) in particular move in converging directions until they reach the two reference stations 2 right upstream and downstream of the signalled fire location 18.
Upon reaching such reference stations 2, the operative extinguishing units 3 (n) , 3 (n+1) are automatically connected to the water and/or fire foam supply line, which are delivered through suitably directed monitors 15. More precisely, the monitors 15 are capable of continuously delivering a controllable stream either as a solid and fog stream.
Additionally, it is possible that the operator takes up the direct control of the fire fighting monitors controlling the extinguishing manoeuvres from the remote control station 4.
A second pair of monitors 3 can be used for cooling purposes. As a matter of fact, in case of long tunnels it is provided for
that the two extinguishing units 3 (n-1) , 3(n+2) adjacent to the two operative extinguishing units 3 (n) , 3 (n+1) be in turn neared and arranged in the reference stations 2 adjacent to the ones between which the fire location 18 is comprised, allowing to use their monitors 15 to reduce the development of heat in the tunnel when necessary.
The extinguishing method proposed is thus of the type concentrated in the fire area and not of the type distributed in advance in a static and uniform manner on the entire route but, in order to guarantee automatic intervention, the extinguishing system must be associated to an automatic fire detection system distributed along the entire length of the tunnel.
The fact that for detection purposes the pre-selected logic is distributed, and hence opposite to the one selected for extinguishing, is directly related to the different operation modes of the two sub-systems of the system. As a matter of fact, while the extinguishing in stand-by conditions is disabled, the detection system continuously operates along the entire length of the tunnel both in stand-by conditions and operating conditions .
The system according to the invention has an extremely quick actuation time.
As a matter of fact, for an effective extinguishing operation it is paramount that the temperature in the tunnel over the entire cycle operations does not reach exceedingly high values.
The extinguishing system intervenes after a period of time resulting from the sum of the actuation time of the detection system and the period of time required by the monitors to reach the reference operating stations upstream and downstream of the fire location and then start delivering the extinguishing substance.
It has been experimentally proved that the fire in the tunnel reaches highest temperatures after a period of time exceeding ten minutes and that the temperatures reached by the fire over the first five minutes do not differ considerably from the temperatures recorded in the environment outside the tunnel .
An extinguishing system according to the present invention is capable of intervening within a period of time less than five minutes on average. Half of this period of time is used by the detection system for signalling the fire location while remaining half of the time is used by the extinguishing system to move the operating moveable extinguishing units to the reference stations identified according to the signalled fire location.
The system can be profitably employed for monitoring and maintenance operations also during normal operating conditions of the tunnel .
This can be performed by means of the cameras with which each moveable extinguishing unit is provided and which can be moved when required by means of a remote control to any fixed
reference station.
Analogously, the monitors can be used for washing and environmental restoration operations.
Lastly, the moveable extinguishing units can be provided with sensors, for measuring the pollution level in the tunnel (CO etc) , which can operate constantly monitoring both the normal traffic flow and the emergency conditions.
The system and method thus conceived are susceptible to various modifications and variants, all of which fall within the scope of the inventive concept; furthermore, all the details can be replaced by technically equivalent elements.
In a different preferred embodiment according to the present invention, the method for extinguishing fire in a tunnel can be static instead of being dynamic, with the extinguishing units being fixed at the reference stations (an extinguishing unit for each reference station) instead of being moveable.
In this case, the method for extinguishing fire in a tunnel comprises the step of installing a series of reference stations fixed along the entire route of the tunnel, the step of installing a series of fixed extinguishing units at the fixed reference stations, the step of installing the system distributed along the route for the detection of a fire location, and the extinguishing step in which the at least the extinguishing units of the fixed reference stations right upstream and downstream of the fire location are operated in
such a manner to quickly counter the fire from oppositely positioned extinguishing points.
Hence, the concept of fighting the fire simultaneously on both of its ends with two independent monitors positioned respectively upstream and downstream of the fire is still valid also in this case, while other two more external monitors provide for the cooling and reduction of the fumes still on both sides of the tunnel if required.
In terms of construction, the monitors of the system provided with fixed extinguishing units are identical to the ones used in the system with moveable extinguishing units and they are provided with a motorised valve on the water- foam supply line.
Also the fire detection logic and the extinguishing operations management logic in the system provided with fixed extinguishing units is identical to the one used in the system provided with moveable extinguishing units, with the sole difference that in this case the monitors are already installed in each fixed reference station and depending on the location of the fire the two monitors for extinguishing and possibly the other two external monitors for cooling are selected, instead of the carriages being moved automatically to the suitable fixed reference stations depending on the location of the fire.
According to the selection performed by the management computer the monitors used are automatically suitably positioned depending on the location of the fire and lastly the water
supply valves are operated (obviously the valves of all the other monitors not involved directly are kept shut during the extinguishing operations) .
