Abstract

The invention relates to an arrangement for extinguishing tunnel fires comprising curtains (3) which separate the tunnel (1) into sections (A). Each section is provided with a feeder device for a fire-prevention material and a fire sensor (2), which in case of a fire in a section, closes the curtains (3) in the section where the fire is and the feeder device for the fire-prevention material is actuated in order to supply the fire-prevention material to said section.

Description

Die Erfindung bezieht sich auf eine Anlage zum Löschen von Tunnelbränden. In letzter Zeit haben sich Tunnelbrände mit immer katastrophaleren Folgen gehäuft. Aufgabe der Erfindung ist es daher, eine wirksame, einfach aufgebaute Anlage zur Bekämpfung von Tunnelbränden bereitzustellen.The invention relates to a system for extinguishing tunnel fires. Tunnel fires have been accumulating with increasingly catastrophic consequences lately. The object of the invention is therefore to provide an effective, simply constructed system for controlling tunnel fires.

Dies wird erfindungsgemäß mit der im Anspruch 1 gekennzeichneten Anlage erreicht. In den Unteransprüchen sind vorteilhafte Ausgestaltungen der Erfindung wiedergegeben. Eine Anlage gemäß dem Oberbegriff des Anspruchs 1 ist in der DE 26 05 598 A1 offenbart.This is achieved according to the invention with the characterized in claim 1 system. In the subclaims advantageous embodiments of the invention are shown. A system according to the preamble of claim 1 is disclosed in DE 26 05 598 A1.

Nach der Erfindung wird in einem Abstand von beispielsweise 50 m bis 200 m jeweils ein Vorhang vorgesehen, der im Brandfall geschlossen, also beispielsweise heruntergelassen werden kann. Damit wird der Tunnelabschnitt verschlossen, wenn durch den Brandsensor in diesem Abschnitt ein Brand festgestellt worden ist. Der Vorhang besteht dabei aus einem nicht brennbaren Material, beispielsweise einem Gewebe aus Fasern aus anorganischem Material.According to the invention, a curtain is provided at a distance of, for example, 50 m to 200 m, which can be closed in case of fire, so for example can be lowered. This closes the tunnel section when a fire has been detected by the fire sensor in this section. The curtain consists of a non-combustible material, such as a fabric of fibers of inorganic material.

Der Vorhang ist vorzugsweise aufgerollt oder zusammengefaltet an der Tunneldecke angebracht. Er besteht aus senkrecht verlaufenden, einander überlappenden Streifen. Damit wird der Vorhang auch dann geschlossen, wenn sich ein Fahrzeug darunter befindet.The curtain is preferably rolled up or folded on the tunnel ceiling. It consists of vertically extending, overlapping strips. This closes the curtain even when a vehicle is underneath.

Wenn ein Fahrzeug in Brand gerät, werden durch den Brandsensor in diesem Abschnitt, beispielsweise einem Rauchsensor und/oder Wärmesensor, die Vorhänge betätigt, also ganz herabgelassen, um den Abschnitt zu schließen, in dem das brennende Fahrzeug sich befindet.When a vehicle burns, the fire sensor in this section, such as a smoke sensor and / or thermal sensor, actuates the curtains, ie, lowers them completely to close the section where the burning vehicle is located.

Gleichzeitig werden die Absperrorgane, die die Öffnungen der Löschmittelleitung zu diesem Abschnitt verschließen, geöffnet. Dazu kann das Absperrorgan beispielsweise als Elektromagnetventil ausgebildet sein, das von dem Brandsensor betätigt, also geöffnet wird. Die Öffnungen können an einer Feuerlöschmittelleitung vorgesehen sein, die sich entlang dem Tunnel erstreckt. Der Abstand der Öffnungen voneinander kann beispielsweise 5 m bis 30 m betragen. Die Öffnungen sind vorzugsweise als Düsen ausgebildet.At the same time, the shut-off devices closing the openings of the extinguishing medium line to this section are opened. For this purpose, the obturator may be formed, for example, as a solenoid valve, which is actuated by the fire sensor, that is opened. The openings may be provided on a fire extinguishing conduit extending along the tunnel. The distance of the openings from each other, for example, 5 m to 30 m. The openings are preferably formed as nozzles.

Als Feuerschutzmittel wird vorzugsweise Halon verwendet. Der schon gebildete Rauch wird dann von den Ventilatoren in dem Tunnel abgesaugt. Auch können sofortige Rettungsaktionen beginnen, da wenig Rauch und Hitze entstehen kann. Die Fenster der Fahrzeuge sollen dabei geschlossen und die Lüftung ausgeschaltet werden, damit im Fahrzeug hinreichend Sauerstoff zur Verfügung steht, bis das Halon von den Abluftventilatoren abgesaugt wird. Da es sich schnell wieder verflüchtigt, kann das Halon zu keinen größeren gesundheitlichen Schäden führen.As a fire retardant halon is preferably used. The already formed smoke is then sucked by the fans in the tunnel. Also, immediate rescue operations can start, as little smoke and heat can arise. The windows of the vehicles should be closed and the ventilation switched off so that sufficient oxygen is available in the vehicle until the halon is sucked off the exhaust fans. As it evaporates quickly, the halon can not cause any major health damage.

Um einen Brand im Wagen einer Standseilbahn zu löschen, die durch ein Tunnel fährt, kann der Wagen einen Feuerlöschmittel-Vorratsbehälter aufweisen, der eine Feuerschutzmittel-Zufuhreinrichtung im Wagen versorgt. Zudem weist der Wagen einen Brandsensor auf, also z.B. einen Rauchmelder oder einen Wärmesensor, der im Brandfall die Feuerschutzmittel-Zufuhreinrichtung zur Zufuhr von Feuerschutzmittel betätigt. Als Feuerschutzmittel wird dabei ebenfalls Halon bevorzugt.In order to extinguish a fire in the tramway car that passes through a tunnel, the trolley may include a fire extinguisher reservoir that supplies a fire retardant supply device in the car. In addition, the car has a fire sensor, for example, a smoke detector or a heat sensor, which operates in the event of fire, the fire retardant supply device for supplying fire retardants. Halon is also preferred as the fire-retardant.

Anliegend ist eine Ausführungsform der erfindungsgemäßen Anlage anhand der Zeichnung beispielhaft näher erläutert. Darin zeigen:

Fig. 1
einen Querschnitt durch ein Tunnel mit an der Decke aufgerolltem Vorhang;
Fig. 2
eine Ansicht gemäß Fig. 1 jedoch mit herabgelassenem Vorhang; und
Fig. 3
einen Längsschnitt durch eine Abschnitt des Tunnels mit herabgelassenen Vorhängen.
An embodiment of the system according to the invention is explained in more detail by way of example with reference to the drawing. Show:
Fig. 1
a cross section through a tunnel with curtain rolled up on the ceiling;
Fig. 2
a view of Figure 1 but with the curtain lowered. and
Fig. 3
a longitudinal section through a section of the tunnel with lowered curtains.

Gemäß Fig. 1 ist in einem Tunnel 1 an der Decke ein Brandsensor 2 und ein aufgerollter Vorhang 3 vorgesehen.According to FIG. 1, a fire sensor 2 and a rolled-up curtain 3 are provided in a tunnel 1 on the ceiling.

In den Randsteinen auf beiden Seiten erstrecken sich entlang dem Tunnel Leitungen 4, 5, über die ein Feuerlöschmittel, z.B. Halon, zugeführt wird.In the curbs on both sides extend along the tunnel lines 4, 5, over which a fire extinguishing agent, e.g. Halon, is supplied.

Wenn der Brandsensor 2, beispielsweise ein Rauchmelder und/oder ein Wärmesensor, in einem Tunnelabschnitt (A) einen Brand feststellt, werden die beiden Vorhänge 3 dieses Abschnitts herabgelassen (Fig. 3).If the fire sensor 2, for example a smoke detector and / or a heat sensor, detects a fire in a tunnel section (A), the two curtains 3 of this section are lowered (FIG. 3).

Wie in Fig. 2 dargestellt, bestehen die Vorhänge 3 aus senkrechten Streifen 6, die sich überlappen.As shown in Fig. 2, the curtains 3 consist of vertical strips 6 which overlap.

Zugleich wird über Düsen in den Leitungen 4, 5 dem Abschnitt A Feuerlöschmittel zugeführt. Dazu werden die Absperrorgane, die die Düsen verschließen, über den Brandsensor 2 geöffnet. Das gebildete Rauchgas und Halon wird in diesem Abschnitt durch den Ventilator 7 entfernt.At the same time is supplied via nozzles in the lines 4, 5 the section A fire extinguishing agent. For this purpose, the shut-off elements which close the nozzles are opened via the fire sensor 2. The flue gas and halon formed is removed in this section by the fan 7.
