  • the invention relates to a device for flushing a wastewater pipeline, a quantity of water being passed through the pipeline with the aid of compressed air, with a compressor and a pressure vessel connected thereto, which is connected to the pipeline via a valve, and with a Storage tank for collecting the amount of water that is supplied via a water inlet.
  • the waste water pipes must be designed in such a way that checks and maintenance work (video inspection, flushing, etc.) are possible.
  • the lines are usually laid in a straight line.
  • Inspection shafts must be arranged at break points (for horizontal or vertical changes in direction). As a rule, these inspection shafts are located at intervals of 10 m to 150 m, depending on the type of terrain. These inspection shafts make the construction of the sewage pipes even more expensive and, moreover, they are disruptive in the area of agricultural areas. Because of the straight line of the sewage pipes between the shafts there are often extremely large installation depths, up to several meters deep, whereas a depth of approximately 1.30 m would usually suffice in view of the required frost protection. Incidentally, inspection shafts and connecting pieces represent potential weak points with regard to the risk of leaks, different settlements, etc.
  • the cost of the sewer pipe can be reduced to half the cost of conventional straight pipe sewer pipes or even less. In view of the large lengths that are usually necessary in rural areas, the additional costs for the compressed air station are therefore no longer significant.
  • Waste water pipeline so that when pressurized with compressed air, a sufficiently large water plug is pushed through the waste water pipeline at the required speed.
  • the air pressure is determined depending on the length of the pipeline, an overpressure of 1 or 2 bar will usually be sufficient. Accordingly, the pressure test is to be carried out in the storage tank, which is of course designed to be closed except for the inlets and outlets, which results in a wide variety of conventional designs.
  • the pressure vessel can be formed from concrete, from metal or from plastic, in particular from fiber-reinforced plastic material. In normal operation, the wastewater flows through the pipeline in a free gradient.
  • the storage tank For flushing, preferably once a week, the storage tank is pressurized with compressed air from the pressure vessel, the storage tank being shut off from the inlet so that the pressure development or the transport of the water plug only takes place in the desired direction through the waste water pipeline.
  • the valve present in the connection between it and the pressure vessel is opened.
  • the storage tank itself could be a separate water tank that is parallel to the sewage pipe and connected to it if necessary (when flushing), in which case the sewage pipe would have to be shut off above the connection of the storage tank to the sewage pipe.
  • the storage tank is preferably integrated in the waste water system, ie the waste water flows coming from a storage channel, storage tank, etc. via the inlet, ie the inlet line, through the storage tank and from there into the waste water pressure line, and the like. in normal operation.

  • the control unit can also be assigned to the compressor so that the compressor only generates the pressure in the pressure vessel at the desired level, so that the pressure build-up only occurs automatically immediately before a flush, before the shut-off device and the valve are then activated.

Abstract

L'invention concerne un procédé et un dispositif pour rincer périodiquement une canalisation d'eau usée (1). Selon l'invention, une quantité d'eau est recueillie dans un collecteur (8) qui est relié à l'extrémité d'entrée de la canalisation (1) à la manière d'une cuve communicante et qui est alimenté périodiquement en air comprimé par l'intermédiaire d'un réservoir de pression, tandis que l'arrivée d'eau vers le collecteur (8) est obturée au moyen d'une unité d'obturation (13) pour faire passer par à-coups la quantité d'eau contenue dans le collecteur à travers la canalisation (1) au moyen de l'air comprimé.
