Abstract

There is often a sedimentation problem, in particular in combined-sewage syphons where water management for residential areas is concerned. This is caused by flow rates which are too low in the event of dry-weather flow. Consequently, in turn, backwater, etc. arises in the event of rainwater flow. In order to eliminate or reduce the sediment problem, the invention proposes to operate the syphon, in the event of dry-weather flow, at times as a partially filled line. This operating method is provided by arranging an additional, smaller line in the rising syphon branch in conjunction with a pump. During pump operation with partial filling, sediments are flushed out of the syphon.

Description

In Dükern, insbesondere auf dem Gebiet der Siedlungswasser­ wirtschaft und hier wiederum bei Mischwasserdükern, be­ steht häufig das Betriebsproblem durch Sedimente. Die für den Regenwetterfall bemessenen Düker haben bei Trocken­ wetterabfluß zu geringe Fließgeschwindigkeiten, um die mit­ geführten, absetzfähigen Stoffe zu transportieren.In culverts, especially in the area of urban water economy and here again with mixed water culverts, be there is often the operational problem due to sediments. The for the culverts dimensioned for rainy weather have dry conditions flow rate too low to keep up with to transport guided, removable substances.

Hierdurch kommt es in dem Düker zu Ablagerungen, die bei Regenwetterabfluß den Fließquerschnitt einschnüren und zu verschiedenen Problemen führen.This results in deposits in the culvert Rainwater runoff constricts and closes the flow cross section cause various problems.

Erfindungsgemäß wird in dem steigenden Dükerast eine zusätzliche Leitung vorgesehen, die in Verbindung mit einer Pumpe gebracht wird, welche je nach den Umständen am unteren oder oberen Leitungsende vorgesehen werden kann. Die von der Pumpe geförderten Wassermengen werden in den weiter­ führenden Kanal geleitet.According to the invention in the rising culvert branch additional line provided in connection with a Pump is brought, which depending on the circumstances at the bottom or upper end of the line can be provided. The Amounts of water pumped are pumped into the leading channel.

Gemäß Fig. 1 wird im Normalfall der Düker 1 durch den Was­ serstand 2 gekennzeichnet. Bei geringem Wasserzulauf 3 können sich in 1 Ablagerungen 4 bilden. In dem steigenden Dükerast 5 wird eine zusätzliche Leitung 6 angeordnet, welche in Verbindung mit einer Pumpe 7 steht, welche am unteren oder oberen Ende des Dükerastes 5 angeordnet sein kann. According to Fig. 1 of the culvert 1 by the What serstand 2 is in the normal case. If the water supply 3 is low, deposits 4 can form in 1 . An additional line 6 is arranged in the rising culvert 5 , which is connected to a pump 7 , which can be arranged at the lower or upper end of the culvert 5 .

Bei Pumpbetrieb wird der Wasserstand in dem Düker 1 auf die Marken 8 gebracht.When pumping, the water level in culvert 1 is brought to marks 8 .

Da gemäß Fig. 2 dann nur noch ein kleiner Fließquerschnitt 9 besteht, erhöhen sich die Fließ­ geschwindigkeiten und führen zu einer Beseitigung der Ablagerungen 4, welche über die Leitung 6 in den Ab­ laufkanal 10 transportiert werden. Durch eine hier nicht weiter beschriebene Ausgestaltung der Erfindung können auch 4 aus dem Dükerast 5 beseitigt werden.Since there is then only a small flow cross section 9 according to FIG. 2, the flow speeds increase and lead to an elimination of the deposits 4 , which are transported via the line 6 into the run channel 10 . By means of an embodiment of the invention which is not further described here, 4 can also be removed from the culvert 5 .

Ein weiterer Vorteil der Erfindung ist der automatisch erfolgende, hydraulisch betriebene Lufttransport durch den Düker bei Pumpbetrieb aufgrund des schießenden Ab­ flusses im fallenden Dükerast. Des weiteren besteht in einer weiteren Ausgestaltung ein Luftgebläse vorzusehen, welches bei Wasserpumpbetrieb Sielgase durch den Düker absaugen kann.Another advantage of the invention is automatic hydraulically operated air transport through the culvert when pumping due to the shooting down river in the falling culvert branch. Furthermore there is in to provide an air blower in a further embodiment, which during the water pumping operation sielgase through the culvert can suction.
