Definitions

  • the invention relates to a method for flushing a course of the sewage following a course of the course of the course, which has at least one low point, by means of compressed air, wherein an amount of water which is collected in a storage container, which is connected to the pipeline, is passed into the pipeline.
  • the invention relates to a in use position a terrain course following Abwasser-Ge conventionalrohr endeavor having at least one low point, with a device for flushing the pipeline by means of conductive by the pipeline, pressurized air water, with a compressor and an associated pressure vessel , which is connected to the pipeline via a valve, and with a storage container for collecting the amount of water, as well as with a water inlet, wherein water can be supplied via the water inlet to the storage container.
  • the drains must be designed so that checks and maintenance (video, flushing, etc.) are possible.
  • the lines are laid straight.
  • inspection shafts must be arranged. As a rule, these inspection shafts are available at intervals of 10 m to 150 m, depending on the respective terrain. These manholes further increase the cost of constructing the sewers and, moreover, they are in the range of agricultural used surfaces disturbing. Because of the straight-line course of the sewers between the shafts, extremely large laying depths often result, up to several meters deep, whereas a depth of approx. 1.30 m would usually be sufficient in view of the required frost resistance. Moreover, 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 or even less than that required for conventional straight line sewer pipes.
  • the additional costs for the compressed air station are therefore no longer significant.
  • US Pat. No. 3,590,836 A discloses a sewage delivery system for introducing wastewater into a main line, with several connecting lines leading into the main line.
  • this is not a wastewater gradient pipeline following the course of the terrain. Rather, the main line to a pressure source for the promotion of sewage.
  • the main line is connected to a plurality of collection containers, into which only occasionally from individual seizure points, e.g. Toilets or the like., Wastewater is supplied.
  • Such collection containers are therefore filled only in intermittent accumulating wastewater and only in the case of overloads of pipe cross-sections.
  • the inventive method of the type mentioned is accordingly characterized in that the collected amount of water held in the siphon-like and connected in the manner of a communicating vessel connected to the Ge specificrohr ein, sufficiently pressure-resistant running storage container and periodically, while the water supply is shut off to the storage tank, with, the compressed air is applied to push the amount of water held, at least a partial volume of the held amount of water jerky with the aid of compressed air from the storage tank into the pipeline.
  • the device according to the invention of the type mentioned is characterized in that the storage container is siphon-like and connected to the pipeline in the manner of a communicating vessel, and that the pressure vessel with the pipeline via the sufficiently pressure-resistant running storage container with the interposition of the valve between the Pressure vessel and the storage container, is connected, wherein in the water inlet to the storage tank a shut-off device, eg a slider is arranged.
  • a shut-off device eg a slider
  • the storage tank has sufficient for the desired Spülwasser volume, eg 2m 3 (2000 liters), depending on the cross section of the sewage pipeline, so as to press a sufficiently large Wasserpfropfen at the required speed through the sewage pipeline when exposed to compressed air.
  • the air pressure is determined depending on the length of the pipeline, with an overpressure of 1 or 2 bar will usually be sufficient.
  • pressure-resistant is the - of course executed except for the inlets and outlets executed - storage tank, which arise for this purpose a variety of conventional types.
  • the pressure vessel may be made of concrete, of metal or else of plastic, in particular of fiber-reinforced plastic material. In normal operation, the wastewater flows through the pipeline in free fall.
  • the storage tank For rinsing, preferably once a week, the storage tank is pressurized with compressed air from the pressure vessel forth, the storage tank is shut off from the inlet, so that the pressure development or the transport of the water plug only in the desired direction, through the sewage pipeline.
  • the existing in the connection between this and the pressure vessel valve is opened.
  • the storage tank is integrated into the sewage system, ie the sewage flows from a storage channel, storage tank etc. coming via the inlet, ie the supply line, through the storage tank and from this further into the sewage pressure line, in normal operation.
  • the waste water itself which collects in the storage tank, is used for the flushing purposes, wherein the storage tank is connected in a siphon-like manner and in the manner of a communicating vessel with the Falnellerohr admir.
  • the sewage pipeline For a simple connection to the sewage pipeline, it is expedient for the sewage pipeline to be connected to the storage vessel via a line section ascending in the bottom area of the storage tank and rising therefrom to a level slightly below the top of the storage tank.
  • the volume of the storage container can be designed such that when rinsing the pipeline several rinse bursts are delivered in a row, which are each carried out with a corresponding amount of water, and in this case, the storage tank is subjected several times sequentially with compressed air.
  • This control can be automatically initiated, as in the case of a simple water purging burst by an electronic control unit, which is provided with a time measuring unit (clock), and which at least the shut-off device in the water inlet to the storage tank and the valve between the pressure vessel and the storage tank is assigned for automatic operation.
  • the control unit can also be assigned to the compressor so as to automatically cause the pressure build-up immediately before a rinse before then the shut-off and the valve are controlled.
  • the water plug In the rinse, the water plug is forced into the sewage pipeline by the pressure in the pressure vessel, at a corresponding rate, e.g. 6 or 7 m / s or more, flows through.
  • a wastewater pipeline (pressure line) 1 is illustrated following an only schematically drawn terrain course 2, wherein by way of example a low point 3 with a kind of siphon for the wastewater in the pipeline 1 is shown, whereby a "water plug" is obtained.
  • a low point 3 with a kind of siphon for the wastewater in the pipeline 1 is shown, whereby a "water plug" is obtained.
  • such Wasserpfropfen are usually not sufficient to rinse the sewage pipeline 1, so as to prevent a build-up of solids and a line growth.
  • a preparation of solids on the line is conceivable, so that even there rinsing is required.
  • Düker in the pipeline 1 pass below an obstacle such as a riverbed.
  • a rinsing station 4 is provided at the upper end of the pipe 1, through which the waste water, via a supply line 5, e.g. coming from a storage channel or storage tank, the sewage pipeline 1 is supplied.
  • a discharge chute 6 is provided in a gravity channel 7.
  • the rinsing station 4 is designed with a storage container 8, which can be pressurized by a pressure vessel 9, in particular a compressed air tank, via a pressure line 10, in which a valve 11 is arranged.
  • a pressure vessel 9 in particular a compressed air tank
  • a pressure line 10 in which a valve 11 is arranged.
  • For pressure generation serves a connected to the pressure vessel 9 compressor 12th
  • the storage container 8 is connected to the inlet 5 via a shut-off device 13, preferably in the form of a slide. With the wastewater pipeline 1, which is present at the upper end at a height just below the top of the storage container 8, the storage container 8 is connected via a line piece 14 extending from the bottom of the storage container 8 and rising therefrom. Thereby, a kind of siphon or communicating vessel is formed, as indicated by the water level at 15 in Fig.2.
  • wastewater from the supply line 5 flows, with the shut-off device 13 open, to the storage container 8, where a predetermined amount of wastewater is collected, for example with a volume of 2000 liters, and the wastewater then passes via the line piece 14 into the waste water designed as a pressure line Pipeline 1.
  • the valve 11 in the connection line 10 to the pressure vessel 9 is closed during this normal operation.
  • the shut-off device 13 is closed, and the valve 11 is opened to pressurize the water in the storage container 8 (as well as in the line section 14) with pressure, for example of the order of 1 or 2 bar.
  • this Wasserpfropfen which is designated in Figure 2 and also in Figures 3 and 4 with 16, jerkily pushed through the sewage pipeline 1, wherein it passes through this line 1 at a speed of the order of at least 6 to 7 m / s is streaming.
  • This Wasserpfropfen 16 flushes the deposits and deposits in the line 1 away, so that a gradual growth of the line 1 is avoided due to the settling of solids on the pipe walls.
  • an electronic control unit schematically illustrated in FIG. 2 is expediently provided, to which a time measuring device or clock 18 is assigned, and which is activated in a time-controlled manner, for example, once a week at a specific point in time and the shut-off device 13 closes and the valve 11 opens after a sufficient time before the compressor 12th was turned on to ensure the pressure build-up in the pressure vessel 9 for rinsing.
  • the corresponding control lines to the shut-off device 13, the valve 11 and the compressor 12 are illustrated in Fig.2 at 19, 20 and 21, respectively.
  • the control unit 17 can also be designed such that the storage container 8 several times in succession - by repeated opening and closing of the valve 11 - is pressurized to press several Wasserpfropfen one behind the other through the line 1.
  • the storage container 8 may be formed with a correspondingly large volume, and only a partial volume is pressed through the conduit 1 in each case; but it is also conceivable to accumulate each wastewater in the storage tank 8 between the individual water surges; This will be particularly useful if a correspondingly strong sewage inflow is ensured.
  • the collection of corresponding amounts of water can also be monitored by means of level sensors, not shown in detail in Figure 2, the output signals of the control unit 17 are supplied.
  • FIG 3 the normal operation of the rinse station 4 is shown schematically.
  • the valve 11 is closed, the shut-off device 13, however, open, and the wastewater flows, coming from the inlet 5, freely through the system, said water plug 16 is formed in the storage tank 8 and in the pipe section 14.
