Definitions

  • the invention relates to a method for removing ice or press snow layers from traffic areas, in which a liquid, in particular heated water or a solution of a thawing agent, which is optionally heated, is introduced under pressure from the top of the layer to be removed, the Ice or press snow layer is thawed in the area adjoining the interface under the effect of the liquid introduced and the ice and / or press snow layer thus detached is removed from the traffic area.
  • a liquid in particular heated water or a solution of a thawing agent, which is optionally heated
  • a snow removal device is known. This device consists of a vehicle, on the front of which nozzles for spraying hot water onto the snow are mounted. The slush that forms is absorbed and melted by the vehicle. Part of the water produced is heated up and sprayed again onto the snow to be removed.
  • the water is sprayed onto the snow or onto the roadway over a wide area. This means not only that very considerable amounts of water are required, but also that frozen or frozen ice or press snow layers on the road surface are not or only poorly penetrated by the spray jets and are therefore not or only partially dissolved.
  • the invention has for its object to provide a simple and quick effective method for removing ice or press snow layers from traffic areas, and to provide a suitable device.
  • this object is achieved in that the liquid simultaneously from a plurality of high-pressure nozzles, which are arranged in rows running longitudinally and / or transversely to the direction of travel of the vehicle and at intervals of a few centimeters from one another, in the form of bundled, sharp high-pressure jets in a substantially vertical direction with simultaneous cutting of the ice or press snow layers to be removed, is brought through them between the ice or press snow layer and the traffic area. Because the liquid is introduced under high pressure in the form of sharp cutting jets into the layer to be removed, the layer of ice or pressed snow is cut into narrow, breaking strips. The liquid penetrates to the road surface in front and distributed between the ice or press snow layer to be removed and the road surface. Due to the pressure and thawing effect of the liquid, the layer of ice or pressed snow is detached from the traffic area, so that it can then be easily removed, for example with a scraper.
  • the ice or press snow layer is cut into smaller pieces and broken at the same time because the detached, crushed ice or press snow parts or the like, for example with the aid of a snow plow, a sweeper. can be easily removed.
  • the saving of time is primarily due to the fact that the boundary layer between the traffic area and the ice or press snow layer is thawed quickly and that there is no need to wait until the entire layer has been thawed or at least converted into slush.
  • the process according to the invention also has the advantage that a solution of a thawing agent does not necessarily have to be used as the liquid, since in certain cases (for example at not too low temperatures) it is sufficient to use water as the liquid, which can be preheated if necessary.
  • Thawing agents that can be used in the form of an aqueous solution in the context of the invention are various glycols (monoethylene glycol, diethylene glycol, dipropylene glycol, monopropylene glycol), a mixture of alcohol and glycol and organic salts such as calcium chloride, sodium chloride and magnesium chloride.
  • the device according to the invention as claimed in claim 3 is particularly advantageous for carrying out the method according to the invention since it is simple to use and handle.
  • the device can be adapted in a simple manner to the respective working conditions by both the angle at which the liquid jets are applied to the ice or press snow layer and the height from the the liquid is applied, can be adjusted accordingly.
  • a plurality of nozzle tubes has, several jets of liquid can act in succession on the same point, so that it is not necessary to travel several times over the traffic area to be cleared of the ice or press snow layer.
  • the device shown in the drawing for detaching ice or press snow layers from traffic areas has a frame 1 which has two side parts 2 which are essentially L-shaped in side view and which are connected to one another in a stiffening manner by transverse bars 24, 25.
  • Carrier 4 is provided for fastening the frame 1 to the front of a vehicle 31, which is provided with a lifting cylinder 5 'articulated in the middle of the frame 1 on a support bracket 5'. With the help of this lifting cylinder 5 ', the frame 1 can be raised and lowered.
  • skids 7 are fastened with the aid of screws 8.
  • Each nozzle tube 10 is equipped with a plurality of high-pressure nozzles 11 pointing downwards.
  • twenty high-pressure nozzles 11 are provided on each nozzle tube, the nozzle bores of which have a diameter of 0.1 to 1 mm, preferably 0.3 to 0.5 mm, and which generate a sharp, bundled, cutting liquid jet.
  • each nozzle tube 10 has at its two ends adjacent to the horizontal legs 6 of the side parts 2 of the frame 1 in each case an end plate 12 provided with a threaded bore, into which an adjusting screw 13 is screwed.
  • the set screw 13 is rotatably received with its lower end portion in a support bearing 14 but axially fixed.
  • the support bearings 14 are connected by screws 15 to the horizontal legs 6 of the side parts 2 of the frame 1. By turning the set screws 13, the Nozzle tubes 10 can be adjusted vertically relative to the skids 7.
  • the height (FIG. 4) is usually set to values between 50 and 80 mm.
  • the nozzle tubes 10 are pivotable in the frame 1 about the horizontal axis of the support bearing 14, so that the liquid jets emerging from the high pressure nozzles 11 strike the top 16 of an ice or press snow layer at an angle which is less than 90 °.
  • the end sections of the adjusting screws 13 accommodated in the support bearings 14 can be fixed against rotation by means of clamping screws 17, which are provided with a conical clamping pin 18.
  • a distributor pipe 20 is arranged between the vertical legs 3 of the side parts 2 of the frame 1, from which a plurality of lines 21 extend, each of which leads to the individual nozzle pipes 10.
  • Each line 21 is provided with an electromagnetically actuated shut-off valve 22, so that one, two, three or all four nozzle tubes 10 can be acted upon with pressurized liquid.
  • a liquid 23 having a pressure of up to 70 MPa (preferably up to 20 MPa) is supplied to the distribution pipe 20 by a high pressure pump 33 which is mounted on the vehicle 31 (FIGS. 5 and 6). You can at the same time with a facility for Preheat the liquid supplied to the nozzle pipes 10 via the distributor pipe 20.
  • the high-pressure nozzles 11 of the respective neighboring nozzle tubes 10 are arranged in a gap with respect to one another, so that the high-pressure nozzles 11 of the first and third nozzle tubes 10 and high-pressure nozzles of the second and fourth nozzle tubes 10, as seen from the front, are each aligned, ie lie on a common line parallel to the direction of travel. While the distances between the nozzle tubes 10 should not be greater than 30 cm, a maximum of about 15-20 cm is expedient for the distances between the individual rows of nozzles. With smaller distances between the rows of nozzles, however, the work output is greater.
  • a 1 to 2 cm thick layer of press snow could easily be detached from a traffic area at a driving speed of 10 km / h.
  • Twenty high-pressure nozzles 11 with a nozzle bore of 0.3 mm diameter were attached to a nozzle pipe of 220 cm length, which were charged with water at 8 ° C under a pressure of 20 MPa with a total of 60 g water / m2 traffic area.
  • the angle at which the nozzle axes were directed against the top of the press snow layer was 60 °.
  • a storage tank 32 for the liquid for the liquid, the high pressure pump 33 and the associated drive motor 34 are arranged.
  • a heating device can be assigned to the storage tank 32.
  • This heating device can be a heating cartridge inserted via the filling opening of the storage tank 32.
