Definitions

  • Tunnel walls and / or tunnel ceilings are subject to the Vehicles passing through a tunnel of heavy pollution, so that cleaning is required at regular intervals is. If the tunnel walls are smooth with tiles or the like Materials are formed, as is the case with car tunnels Is usual, cleaning with roller brush systems under Add water. A corresponding tunnel cleaning machine to carry out this procedure is through the German interpretation 16 58 405 known.
  • washing liquid does indeed work with the mechanical one Assistance by cleaning the brush Tunnel walls, nevertheless stick to the well-known tunnel washing vehicle and the serious procedure carried out with this Disadvantages.
  • the use of washing liquid and water leads to undesired drenching of the traffic area or the floor, and it should also be borne in mind that in addition to the high water consumption that is contaminated with dirt Water gets into the sewage system. It is also at Use of water particularly disadvantageous because of the Use of water the risk of cable fires in the Existing electrical lines or also in the existing electrical switch boxes is given.
  • the invention has for its object a method for Cleaning of tunnel walls and tunnels to create which wet the tunnel floor with simple means and pollution of the sewage systems with dirty water avoids, and which also the danger of cable fires and short circuits eliminated.
  • the invention is also the Task based on a device for performing a to provide such a method.
  • This task is performed in a method for cleaning tunnel walls and / or tunnel ceilings of a tunnel of dusty stuck deposits and dirt from the Features of claim 1 and in a device for Carrying out such a process by the features of claim 3 solved.
  • the method according to the invention is based on the fundamental Thoughts when cleaning tunnel walls by adding to produce an aerosol from water in a stream of compressed air which is sprayed with pressure against the tunnel walls and dissolves the dirt and forms in a dusty atmosphere of an air-dirt-water mixture.
  • the water consumption becomes significant reduced because the compressed air flow is comparatively little Water needs to be added.
  • To generate the aerosol serve several blowing nozzles that are spaced from the Tunnel wall or tunnel ceiling of the circumference of a nozzle hood distributed and provided with one injector each are.
  • A is used to extract the dust-containing atmosphere suction hood arranged at a distance from the nozzle hood with at least a suction arrangement is used, the suction hub essentially the same dimensions and the same shape as the nozzle hood has.
  • An important aspect of the invention is that through the nozzle hood and the Suction hood a suction chamber is formed such that the Tunnel cross-section through the nozzle hood in the direction of travel at the front and through the suction hood in the direction of travel to the rear is predominantly sealed. This ensures that not the dusty atmosphere with the loosened dirt remains, but be vacuumed into a dirt container can.
  • Both the nozzle hood and the suction hood extend thus not all the way to the tunnel wall, but end at a distance from the tunnel wall, so that the aforementioned from the parts of the tunnel wall projecting on the one hand not from the both hoods are touched, but on the other hand with the Water supplied compressed air flow for cleaning become. Since only comparatively little water is used is also extracted and the dusty atmosphere generated the use of water is not a problem, so that, for example, cable fires or others through a Exposure to water prevents possible consequential damage.
  • the sewage systems are cleaned by cleaning the tunnel walls not at all polluted because of the dusty atmosphere is collected in a closed dirt container. Out for this reason, there is also advantageously no Soaking the tunnel floor.
  • the method provides for several blowing nozzles from one common ring line are fed and that several Ring lines with their own blowing nozzles are used, the ring lines being operated in a pulsating manner, that only a part of all blowing nozzles, preferably only a third, at the same time spraying a compressed air / water mixture.
  • the inventive device for performing the method includes the nozzle hood already mentioned, which runs along the Tunnels can be moved and are at a distance from the tunnel wall or extends from the tunnel ceiling. On the circumference of the nozzle hood are several distributed with an injector Blow nozzles arranged, which are directed to the tunnel wall.
  • Blower nozzles From those arranged at a safe distance from the tunnel wall Blower nozzles enter a compressed air / water mixture directed towards the tunnel wall which forms an aerosol and which on the Debris and dirt and stuck deposits Dust dissolves and creates a dusty atmosphere.
  • the device according to the invention also arranged movably Suction hood with essentially the same dimensions and the same shape as the nozzle hood.
  • the suction hood has at least one suction arrangement for vacuuming the dusty Atmosphere in one of the nozzle hood and the suction hood Formed suction chamber is arranged, the nozzle hood and the suction hood are designed such that the tunnel cross section in the direction of travel forward through the nozzle hood and predominantly in the direction of travel to the rear through the suction hood is sealable.
  • the nozzle hood comprises adjustable segments, each with a variety are arranged by blowing nozzles, the segments being radial towards the tunnel wall as well as in opposite Direction are adjustable.
  • suction hood adjustable Includes segments that are radial towards the tunnel wall and adjustable in the opposite direction.
  • adjustable segments can also be adjustable Bulkheads may be provided.
  • Another expedient embodiment of the invention provides before that the outer edge of both the nozzle hood and the Suction hood is provided with an elastic hood end.
  • This elastic hood end extends further towards the tunnel wall as the nozzle hood and the Suction hood itself.
  • the elastic hood ends can definitely with those that protrude from the tunnel wall Parts and railway equipment in contact come. However, this is not annoying because of the elastic Design of the hood ends z. B. in the form of Rubber will not damage the railway equipment.
  • the elastic hood ends an even better if not complete seal of the tunnel through the nozzle hood and through the suction hood achieve, reducing the effectiveness of between the nozzle hood and the suction hood located suction chamber increased becomes.
  • FIG. 1 shows a tunnel 10 as a railway tunnel with a tunnel wall 12.
  • a towing vehicle 16 which is coupled to a wagon 14.
  • nozzle hood 18 At the rear end of the towing vehicle 16 there is a nozzle hood 18, and further are on the towing vehicle 16 Water tank 32 and a compressor 34 for the operation of the nozzle hood 18 provided.
  • a suction hood 20 is arranged at the front end of the wagon 14, which comprises a suction funnel 22. Also located a dirt container 26 and one on the wagon 14 Fan 28 with an exhaust duct and a motor 30 for the Operation of the suction hood 20.
  • the outer dimensions of the nozzle hood 18 are less than the inner cross section of the tunnel 10 in such a way that any existing and projecting from the tunnel wall 12 inwards Parts of the nozzle hood 18 while driving through the Tunnels are not touched.
  • the nozzle hood 18 has one elastic hood end 56, through which the outer dimensions the nozzle hood 18 can be enlarged, but the is always at a distance from the tunnel wall 12 and thus leaves a gap. This gap is important thus an air flow 52 through it into a suction chamber 24 can get through the space between the nozzle hood 18 and the suction hood 20 is formed.
  • the mentioned by the Tunnel wall 12 excellent parts are through the hood closure 56 not damaged because the hood end 56 is elastic and can avoid these parts.
  • the suction hood 20 has approximately the same external dimensions like the nozzle hood 18 and is also with an elastic Hood cover 54 provided the same function how the elastic hood end 56 of the nozzle hood fulfills.
  • the elastic hood end 54 also allows one Gap free, through which an air flow 52 into the suction chamber 24 can reach.
  • the tunnel 10 or the corresponding tunnel cross section is so through the nozzle hood 18 and Suction hood 20 predominantly, but because of the column mentioned not fully sealed. However, the seal is sufficient enough that between the nozzle hood 18 and the Suction hood 20 can form the aforementioned suction chamber 24.
  • FIG. 2 shows an example of a cross section of a tunnel 10, which is formed by a tunnel tube 36.
  • Tunnel lighting 38 and various supply lines are such 40 as required railway facilities intended.
  • These parts face the tunnel wall 12 outstanding parts and are allowed to drive with the towing vehicle 16 are not damaged. For this reason a clearance profile is shown in Fig. 2, which the Delimits the area of the tunnel cross-section that is absolutely free is to be kept in order to damage the railway equipment to avoid.
