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 broom systems under Add water. A corresponding tunnel cleaning machine is by 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 serious disadvantages.
the use of washing liquid and water leads to unwanted soaking the traffic area or the ground, and it must also be taken into account that in addition to the high water consumption with the Dirty water gets into the sewage system. Furthermore it is particularly disadvantageous when using water, that through the use of water there is a risk of cable fires with the existing electrical lines in the tunnel or also given with the existing electrical control boxes is.
the invention has for its object a device to create tunnel walls and ceilings, which with simple means wet the tunnel floor as well as pollution of the sewage systems with dirty Water avoids, and which also the danger of cable fires and short circuits eliminated.
the invention is based on the basic idea that Cleaning tunnel walls by adding water to one Compressed air flow to produce an aerosol that works with pressure is sprayed against the tunnel walls and loosens the dirt and in a dusty atmosphere in the form of an air-dirt-water mixture transferred. Compared to known solutions this significantly reduces water consumption because only relatively little water added to the compressed air flow needs to be.
Several are used to generate the aerosol blow nozzles each arranged on the circumference of a nozzle hood an injector.
A is used to extract the dust-containing atmosphere suction hood arranged at a distance from the nozzle hood is used.
An important aspect of the invention is that a suction chamber is formed between the nozzle hood and the suction hood is, and this ensures that the dusty Atmosphere with the loosened dirt does not remain, but can be sucked into a dirt container.
Both the nozzle hood and the suction hood extend 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 do not touch the two hoods be, but on the other hand with the water Compressed air flow for cleaning. Because only comparatively little water is used and also the generated dust-containing atmosphere is extracted, the Use of water no problems, for example cable fires or others possible through exposure to water Consequential damage is avoided.
the sewage systems are not burdened at all by cleaning the tunnel walls, because the dusty atmosphere in a closed Dirt container is collected. For this reason, it is omitted advantageously also a wetting of the tunnel floor.
the inventive device for performing the method includes the nozzle hood already mentioned, along the tunnel is movable and 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.
a compressed air / water mixture is 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 tunnel is facing forward is largely sealed by the nozzle hood.
Seen in the direction of travel behind the nozzle hood includes the invention Device also arranged to be movable Suction hood with essentially the same dimensions and same shape as the nozzle hood.
the suction hood has at least a suction arrangement for extracting the dusty atmosphere, which is in the space between the nozzle hood and the suction hood is located. It is still an advantage that the tunnel through the suction hood largely in the direction of travel is sealed to the rear so that between the Nozzle hood on the one hand and the suction hood on the other Suction chamber is formed.
the nozzle hood comprises adjustable segments, each with a variety of blowing nozzles are arranged, and the radially towards the tunnel wall and adjustable in the opposite direction are.
the size or the outer Dimensions of the suction hood are changeable.
the size or the outer Dimensions of the suction hood are changeable.
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 closure extends further towards the tunnel wall as the nozzle hood and the Suction hood itself.
the elastic hood ends definitely with those that protrude from the tunnel wall Parts and railway equipment in contact come.
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.
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 closure 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 so on 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 from the Tunnel wall 12 outstanding parts are covered by the hood 56 not damaged because the hood end 56 is elastic is trained and can avoid these parts.
the suction hood 20 has approximately the same outer dimensions like the nozzle hood 18 and is also with an elastic Hood cover 54 provided the same function how the elastic hood closure 56 of the nozzle hood meets.
the elastic hood closure 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 through the nozzle hood 18 and the suction hood 20 mostly, but not because of the column mentioned completely 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.
FIG. 3 shows adjustable segments 48 of the nozzle hood 18 shown, together with an adjustable bulkhead 46. Sensor-controlled pneumatic cylinders are used for the adjustment 50 provided.
the dashed line 44 indicates the vehicle body of the towing vehicle again.
Fig. 4 the segments 48 and the bulkhead 46 in the extended Position.
the pneumatic cylinder 50 By actuating the pneumatic cylinder 50 has the outer circumference of the nozzle hood 18 is enlarged.
the individual adjustable segments 48 can if necessary overlap and in different parallel planes are located.
blowing nozzles 58 which are provided on the nozzle hood 18 are and expediently on the adjustable Segments 48 are located.
the blowing nozzles 58 are on the outer edge the adjustable segments 48 arranged so that they are in are close to the tunnel wall 12.
FIGS A plurality of blowing nozzles 58 are shown in FIGS a common first ring line 60 and a second Ring line 62 fed; 7 is a third one Ring line 64 and a fourth ring line 66 shown.
hose connections 70 are provided around connect to adjacent segments 48.
each blowing nozzle 58 produces each blowing nozzle 58 a compressed air water mixture or a compressed air water jet 68, which is directed to the tunnel wall 12.
a compressed air water jet 68 becomes the dirt from the tunnel wall 12 solved and transferred into a dusty atmosphere.
the dusty atmosphere is an air-dirt-water mixture 72 (see FIG. 1), the water content is comparatively small.
the suction funnel 22 is also the largest Part of the water used for cleaning is also collected. The bottom of the tunnel 10 is therefore subject to practical conditions no drenching.
the different Ring lines 60 - 66 operated pulsating, so that from only a part of all of the blowing nozzles 58 involved is and the compressed air / water mixture 68 sprays.
the blow nozzles in this way work pulsating that only a third of the blow nozzles 68 is in use at the same time.
