Definitions

  • the invention relates to a first Invention ideas a method in the preamble of Claim 1 specified type and goes according to another Invention ideas on a device to Performing this procedure.
  • the one sucked out of the sewer during sewer cleaning Dirt represents a mixture of suspended matter in the essential inform of sand and floating materials, like Faeces, digested sludge, paper, etc.
  • the sediments sediment i.e. settle on the canal floor and narrow the channel cross section. It is therefore desirable to remove the suspended matter. So far, this has required one costly disposal, as a result of pollution Faeces etc. a simple deposit or a Reuse as building material etc. are not possible. This adversely affects the overall cost of the Sewer cleaning and thus the overall economy out.
  • the procedural solution is that the Soiled dirt in sediments and floating materials such as faeces, foul foam, paper etc. is separated that the floating substances in the channel be returned and that of the floating materials freed sediments are discharged.
  • the dirt contained in the absorbed dirt Materials used for clogging the channel cross section are safely returned to the sewer.
  • the sediments will be retained through the mentioned return the previously achieved Cleaning effect not affected.
  • the sediment essentially constituting sand lies at the end of the Process in cleaned form before and can be easily on stored in a landfill or preferred as Recycling material in the construction industry or as Use litter in winter etc.
  • the Measures according to the invention therefore enable the Achieving a high level of efficiency in the Sewer cleaning etc.
  • the dirt holding space fulfills a double function here as storage and treatment room.
  • the air flotation or movement device cause the floating materials be separated from the sediments and go up can rise.
  • the supply of clean water during this separation treatment leads to a quick one increasing purity of the in the treatment room remaining material.
  • the ascending floating substances can after the Water level has reached the height of the overflow weir, with the overflowing water simply into the neighboring one Float the return chamber.
  • the return chamber can therefore also discontinuous emptying comparatively compact be.
  • the measures according to the invention also enable a comparatively simple control of the Cleaning progress from the outside. To do this, only the Degree of purity of the flowing out of the return chamber Water can be observed.
  • the high degree of purity of the im Dirt holding space left behind material advantageously not just reuse or simple landfill. Rather, it is one Temporary storage in the vicinity of the place of use, i.e. in Residential areas etc., containers without set up Odor nuisance etc. and therefore possible without problems what the economy of the device according to the invention can further increase by avoiding long driving times.
  • Another advantage is the fact that as a result of Cleaning a volume reduction takes place, so that available capacity for large too cleaning channel sections is sufficient.
  • Sewer cleaning vehicle contains one on one Vehicle chassis 1 accommodated container assembly, the has at least one centrally arranged barrel 2. This is arranged so that counter-tilting movements with raised rear or front end are possible. This enables rocking movements to be carried out.
  • the container arrangement is in the area of its front and rear end on lifting devices 3, here inform of lifting cylinders articulated on the vehicle chassis 1, pivoted.
  • the barrel 2 On the barrel 2 is one with a standing axis Reel 4 provided on which a pressure-resistant, insich movable suction hose 5 is receivable, the front end can be lowered into the channel to be cleaned and its reel-side end via a rotating union with a throwing neck 6 opening into the barrel 2 is provided. This is in the direction of throw-in opening hinged lid 7 closable.
  • the barrel 2 is one arranged on the chassis 1 air pump 8 assigned can be operated as a vacuum pump and as a pressure pump.
  • a sewer cleaning vehicle of the present type contains also a high-pressure pump, through which one in the cleaning channel lowerable pressure hose, which on is provided with a cleaning nozzle at the front end Rinse water is supplied, what in the drawing Not shown for reasons of clarity.
