Definitions

  • the invention relates to a safety device for fires in tunnels.
  • the object of the invention is to provide a simply constructed safety device in order to prevent the catastrophic consequences of tunnel fires.
  • a curtain is provided in the tunnel at a distance of, for example, 50 m to 200 m, which can be closed in the event of a fire. This closes the tunnel section if a fire has been detected by the fire sensor in this section.
  • the Curtain consists of a non-combustible material, for example a fabric made of inorganic fibers
  • the safety device according to the invention is thus characterized by its simplicity.
  • the fire sensor can be a smoke detector and / or a heat sensor.
  • the curtains can be rolled up or folded onto the tunnel ceiling.
  • the curtains are preferably drawn across the carriageway or, in the case of a railway or funicular tunnel, across the tracks.
  • the curtains are hung from the tunnel wall in the contracted, that is to say folded, state, preferably in a joint provided in the tunnel wall, for example milled joint or the like. Recess.
  • the recess or other space in which the contracted curtains are located can be closed by flaps to protect the curtains from dirt.
  • Each curtain can consist of several parts, in particular two parts or halves, which are arranged in the contracted or folded state on or in one or the other tunnel wall. To close the two curtain parts are pulled towards the opposite tunnel wall. When pulled apart, the curtain parts can thus extend from one tunnel wall to the other, i.e. form a double-walled curtain, but they can also only extend to half the tunnel, but preferably so that they overlap in the middle of the tunnel.
  • the curtains are closed by a motor, for example an electric motor. However, for example, a pyrotechnic motor can also be provided for automatically closing the curtains.
  • the flaps that protect the curtains from dirt can also be opened.
  • the curtains in particular in the lower area, preferably consist of vertical stripes running from top to bottom so that they can be hung over vehicles and the like. Being able to pull objects in the tunnel.
  • the width of the strips can be, for example, 20 cm to 50 cm.
  • the strips are preferably designed such that they overlap when the curtain is pulled apart.
  • two curtain parts can also be provided on each side of the tunnel, which form two curtain sections arranged one behind the other in the contracted state of the curtain.
  • the curtains are pulled together on rails that are provided on or in the area of the tunnel ceiling.
  • multi-track rails are preferably used.
  • each tunnel section at least one device for A bluftabsaugung on.
  • the exhaust air extraction can be formed, for example, by an opening in the tunnel ceiling leading to the Exhaust duct of the tunnel leads.
  • the exhaust air extraction can be formed, for example, by an opening in the tunnel ceiling leading to the Exhaust duct of the tunnel leads.
  • the flap of the exhaust air extraction device in the section with the fire can be opened by the fire sensor, while all or at least some of the flaps of the exhaust air suction devices of the remaining tunnel sections can be closed by the fire sensor.
  • the smoke gases formed can be extracted in a targeted manner.
  • the curtains are designed so that when closed they close the upper area of the tunnel more tightly than the lower area of the tunnel. This ensures that fresh air that is drawn into the section with the fire by the exhaust air extraction flows in at the bottom of the curtains, so that injured persons lying on the tunnel floor have a greater chance of escaping the smoke gases.
  • 80% of tunnel victims die from smoke and not from burns.
  • the fact that the individual curtains are 100 m apart, for example, means that the air is not sucked in so strongly that the fire is additionally lit.
  • the safety device ensures that rescue and fire-fighting vehicles can penetrate from the outside to the section in the event of a fire without being exposed to any significant smoke or heat, which makes rescue measures and fire-fighting and rescue work much easier.
  • the tunnel sections can each be provided with a traffic light, and in the event of a fire, all traffic lights that are in the direction of travel are caused by the fire sensor in front of the section with the fire, on red, and all traffic lights after the section with the
  • Red traffic lights not only stop all oncoming traffic, but also loosen them up, since the individual cars or groups of cars in one
  • the traffic lights switched to green can remove the vehicles that are in the direction of travel after the section with the fire.
  • a loudspeaker or intercom can be installed in each section to steer the person in the right direction.
  • each section can be provided with a video camera so that the accident circumstances can be recorded immediately and the corresponding rescue measures can be taken.
  • each section In order to prevent false triggers, several fire sensors are preferably provided in each section.
  • the curtains in front of and behind each section are only closed in the direction of travel if, for example, at least two fire sensors detect a fire.
  • An impact switch for closing the curtains can also be provided in each tunnel section.
  • the actuation of the individual curtains, the individual sensors, the actuating devices of the flaps on the exhaust air extraction and the dust flaps for the contracted curtains as well as the video cameras can be checked regularly by a central computer.
  • tunnels can be retrofitted at reasonable costs.

  • Fig. 3 shows a longitudinal section through a section of the tunnel with closed curtains.
  • the tunnel is divided into sections A, which can be separated from one another by a fire-resistant curtain 1, which is attached in the direction of travel before and after section A.
  • a fire-resistant curtain 1 which is attached in the direction of travel before and after section A.
