Abstract

Where water management for residential areas is concerned, free-gradient receiving-water pipelines often undergo overloading in the event of rain. It is known that, in the case of storm overflows, excess water is deflected into receiving-water channels or is at times accommodated in retaining basins. In order to eliminate or to reduce constrictions in a drainage system having the possible means of release which have been described, the invention proposes to accelerate a quantity of water in a duct by means of pumps, as a result of which the average flow rate, and thus the transporting capacity of the duct, is increased.

Description

Im Bereich der Siedlungswasserwirtschaft und dort insbesondere bei Mischwassersystemen unterliegen Freigefälle-Vorflutleitungen aus verschiedenen Gründen häufig einer Überlastung. Um hier Abhilfe zu schaffen, werden, falls möglich, Notauslässe angeordnet, die Überschußwasser in Vorfluter abgeschlagen. Hierdurch werden diese verschmutzt. Eine andere Lösung stellen die bekannten Rückhaltebecken dar, welche Wasser aus dem System zeitweise aufnehmen. In Stadtgebieten können solche Becken nur unterirdisch errichtet werden. Standorte für die sehr kostenintensiven Becken sind nur schwer zu finden und ihre Anordnung stößt zu­ nehmend auf Widerspruch.In the area of urban water management and there subject to mixed water systems in particular Free fall drain pipes for various reasons often an overload. To remedy this, if possible, emergency exits are arranged which Excess water chipped off in the receiving water. Hereby they get dirty. Provide another solution the well-known retention basins represent what water from the system temporarily. In urban areas such pools can only be built underground. Locations for the very expensive pools are difficult to find and their arrangement happens taking contradiction.

Die oben beschriebenen Entlastungsmöglichkeiten über­ lasteter Kanäle können u. U. dadurch entfallen, indem erfindungsgemäß die Kapazität der Vorflutkanäle durch künstliche Einleitung von Strömungsenergie erhöht wird. Dieser Vorschlag sieht vor, im Verlauf einer Vorflut­ leitung eine Teilwassermenge der Vorflutleitung mittels Pumpen zu beschleunigen und diese beschleunigte Wasser­ menge wieder der Vorflutleitung zuzuführen. The relief options described above polluted channels can U. thereby eliminated by according to the capacity of the receiving channels artificial introduction of flow energy is increased. This proposal provides for, in the course of a flood pipe a partial amount of water from the receiving pipe Accelerate pumps and this accelerated water quantity to be fed back into the receiving water line.  

Hierdurch wird die mittlere Fließgeschwindigkeit in der Vorflutleitung erhöht und somit auch die Transport­ kapazität vergrößert. Die mit dem Pumpvorgang örtlich bedingte Absenkung des Wasserspiegels in der Vorflut­ leitung könnte auch in der Weise zweckmäßig genutzt werden, als der Absenkungsbereich im Verlauf einer Notentlastungs-Überlaufschwelle liegt und dadurch in Extremfällen entstehende Überlaufereignisse gemindert werden.As a result, the average flow rate in the receiving water line increased and thus the transport capacity increased. The local with the pumping process Conditional lowering of the water level in the receiving water Line could also be used appropriately in this way than the area of subsidence over the course of a Emergency relief overflow threshold is and therefore in Overflow events occurring in extreme cases are reduced will.

Mit diesem Verfahren können die Fließvorgänge in einem Kanalnetz vorteilhaft beeinflußt werden. Voraussetzung ist allerdings, daß an anderer Stelle erhöhte Wassermengen aufgenommen werden können.With this method, the flow processes in a channel network can be influenced advantageously. However, the prerequisite is that elsewhere increased amounts of water can be absorbed.

Verfahren zur Abflußsteigerung in Freigefälle- Vorflutleitungen, dadurch gekennzeichnet, daß im Verlauf der Freigefälle-Vorflutleitung 1 Pumpen 2 vorgesehen werden, welche aus der Leitung 1 Wasser aufnehmen und über eine Leitung 3 das Wasser wieder in 1 einspeisen, die umgepumpte Wassermenge die Geschwindigkeit v 1 = 4 aufweist, welche gegenüber der Geschwindigkeit v 2 = 5 in dem Kanal 1 größer ist und dadurch Strömungsenergie in 1 zu einer Abfluß­ steigerung führt.1. A method for drain increase in Freigefälle- Vorflutleitungen, characterized in that 1 pumps 2 are provided in the course of free downslope Vorflutleitung which receive from the line 1 of water and the water fed back into 1 via a line 3, pumped by circulation amount of water, the speed v 1 = 4, which is greater than the speed v 2 = 5 in channel 1 and thereby flow energy in 1 leads to an increase in outflow. 2.
