Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Entlüftung eines Tunnels jeweils mit den Merkmalen des Anspruches 1 und des Anspruches 3.The invention relates to a method and an apparatus for Ventilation of a tunnel with the characteristics of Claim 1 and claim 3.

Die Entlüftung von modernen Tunnelanlagen erfolgt im Modus des Normalbetriebs dadurch, dass Frischluft in den Tunnel gefördert und die verunreinigte oder verbrauchte Luft aus dem Tunnel abgesaugt wird. Das geschieht durch natürliche Ventilation oder mit Hilfe von Ventilatoren. Die Strömungsführung für die Abluft kann dabei über die so genannte Tunnelkalotte erfolgen, die sich oberhalb des eigentlichen Fahrraums befindet und von diesem durch eine Trennwand abgeteilt ist.Modern tunnel systems are vented in mode Normal operation in that fresh air is conveyed into the tunnel and the polluted or used air from the tunnel is suctioned off. That happens through natural ventilation or with the help of fans. The flow guide for the exhaust air can be done via the so-called tunnel dome, which is located above and from the actual driving space is divided by a partition.

Bei fließendem Verkehr sind im Tunnel unter normalen Betriebszuständen vorhandene Klappen von in der Trennwand angeordneten Absaugöffnungen so eingestellt, dass in einem bestimmten Lüftungsabschnitt der Tunnelkalotte durch jede geöffnete Absaugöffnung ein bestimmter Volumenstrom an verbrauchter Luft abgesaugt wird. Dadurch wird sichergestellt, dass in diesem Lüftungsabschnitt die verbrauchte Luft abgeführt wird.When traffic is flowing, the tunnel is under normal Operating conditions existing flaps of in the partition arranged suction openings so that in a specific ventilation section of the tunnel dome through each open suction opening a certain volume flow used air is extracted. This ensures that the used air is removed in this ventilation section becomes.

Kommt es im Tunnel zu einem Brand, z. B infolge eines Unfalls oder der Motorüberhitzung eines Fahrzeuges, ist es erforderlich, die lebensgefährlichen, heißen Rauchgase in unmittelbarer Umgebung des Brandherdes konzentriert abzusaugen. Hierfür werden in unmittelbarer Nähe des Brandherdes die Absaugklappen geöffnet, während die Klappen, die weiter vom Brandherd entfernt sind, geschlossen werden, so dass die Absaugung der Rauchgase auf den Bereich des Brandherdes fokussiert wird. Infolge von Leckagen z. B. der geschlossenen Klappen oder durch bauseitige Leckagen der Tunnelkalotte bzw. durch eine Systemänderung (Nachrüstung von Klappen) besteht die Gefahr, dass die Absaugleistung der Tunnelventilatoren nicht ausreicht, um am Brandherd eine ausreichende Menge von Rauchgas abzusaugen.If there is a fire in the tunnel, e.g. B as a result of an accident or the engine overheating of a vehicle, it is necessary the life-threatening, hot smoke gases in the immediate vicinity Vacuum the area around the source of the fire in a concentrated manner. For this be in the immediate vicinity of the source of the fire opened while the flaps farther from the source of the fire are closed so that the extraction of the flue gases is focused on the area of the source of the fire. As a consequence of Leakages e.g. B. the closed flaps or by the customer Leakage in the tunnel dome or through a system change (Retrofitting flaps) there is a risk that the Suction capacity of the tunnel fans is not sufficient to Fire source to extract a sufficient amount of flue gas.

Aus der DE 44 42 349 ist eine mobile Lüftungsanlage mit einem Axialventilator bekannt, die unter anderem auch zur Verdrängung von Rauch und Dämpfen in Hallen und Tunnelanlagen verwendet werden kann. Der Einsatz einer solchen Lüftungsanlage zur Kontrolle der Rauchgase innerhalb des Fahrraumes eines Tunnels setzt jedoch voraus, dass der Brandherd zu erreichen ist. Das ist vor allem dann nicht mehr möglich, wenn sich insbesondere in langen Tunnelanlagen der Brand schon ausgebreitet hat und die Umgebung des Brandherdes sehr heiß geworden ist, so dass der eigentliche Brandherd nicht mehr erreichbar ist.DE 44 42 349 describes a mobile ventilation system with a Axial fan known, among other things, for displacement of smoke and vapors used in halls and tunnels can be. The use of such a ventilation system for Control of the flue gases inside a tunnel assumes, however, that the source of the fire can be reached. The is especially no longer possible if, in particular, in long tunnels the fire has already spread and the The area around the source of the fire has become very hot, so that the actual source of fire is no longer accessible.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Tunnelbelüftung so zu gestalten, dass die Brandgase im Fahrraum eines Tunnels in unmittelbarer Nähe des Brandherdes abgesaugt werden können.The invention has for its object the generic To design tunnel ventilation so that the fire gases in the driving area of a tunnel in the immediate vicinity of the source of the fire can be.

Eine Vorrichtung zur Durchführung des Verfahrens ist Gegenstand des Anspruches 3. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The task is in a generic method according to the invention by the characterizing features of Claim 1 solved. A device for carrying out the Process is the subject of claim 3. Advantageous Embodiments of the invention are in the subclaims specified.

Da der zusätzlich zur Tunnelventilation vorgesehene fahrbare Ventilator innerhalb der Tunnelkalotte, also außerhalb des Fahrraumes verfahrbar ist, lässt er sich im Brandfall auch bei starker thermischer Belastung sicher und schnell in eine Position in unmittelbarer Nähe des Brandherdes bringen, ganz gleich an welcher Stelle im Tunnel der Brand entstanden ist. Nach Positionierung und Inbetriebnahme unterstützt der Ventilator die normale Ventilation des Tunnels im Brandfall und sorgt für eine starke Entrauchung des Fahrraumes in unmittelbarer Nähe des Brandherdes. Dadurch können sich die von dem Brandfall betroffenen Menschen in der Tunnelröhre leichter retten, und die Rettungskräfte können schnell sehr nahe an den Brandherd heranrücken, um Rettungsmaßnahmen einzuleiten.Since the mobile in addition to the tunnel ventilation Fan inside the tunnel dome, i.e. outside the Is movable in the event of a fire strong thermal stress safely and quickly in one Position it in the immediate vicinity of the source of the fire, completely no matter where in the tunnel the fire started. After positioning and commissioning, the Fan the normal ventilation of the tunnel in case of fire and ensures a strong smoke extraction from the driving area in immediate vicinity of the source of the fire. This allows the of those affected by the fire in the tunnel tube are easier rescue, and the rescue workers can quickly get very close to the Approaching fire source to initiate rescue measures.
