Description
Die vorliegende Erfindung bezieht sich auf ein Druckleitungsrohr für Flüssigkeiten nach dem Oberbegriff des Anspruchs 1.The The present invention relates to a pressure pipe for liquids according to the preamble of claim 1.
Bei Abwassersystemen, die auf dem Weg zur Kläranlage mit Druckleitungsrohren für das Abwasser ausgestattet sind, besteht ein Problem darin, das Abwasser, das im Abwasserleitungssystem relativ lange Aufenthaltszeiten besitzt, in stets aerobem, dass heißt frischem und sauerstoffreichem Zustand zu erhalten und der Kläranlage zuzuführen. Geht das Abwasser in den anaeroben, dass heißt sauerstofffreien Zustand über, ergeben sich Probleme mit dem sich bildenden Sulfid, nicht nur hinsichtlich Geruchsbelästigung, sondern auch Gefährdung der Arbeitssicherheit des Kläranlagenbetriebspersonals und technischer Probleme bei der Abwasserreinigung.at Sewage systems on the way to sewage treatment plant with pressure pipe for the Sewage, there is a problem with the sewage, that has relatively long residence times in the sewer system, in always aerobic, that is fresh and oxygen-rich state and the sewage treatment plant supply. If the wastewater goes into the anaerobic, that is to say oxygen-free, state problems with the forming sulfide, not only in terms of Odor, but also endangerment the safety at work of the wastewater treatment plant operators and technical problems in wastewater treatment.
Die Bewegung von Luft in Abwasserdruckrohrleitungen wird von der Rauhigkeit der Rohrleitung, sowie der Strömungsgeschwindigkeit und dem Neigungswinkel der Leitung bestimmt. Die freie Bewegung kleinerer Luftblasen endet in der Regel an hydraulischen Hochpunkten oder Zwischen-Hochpunkten. Dort akkumulieren kleine Luftblasen zu größeren Luftansammlungen, was zu einem Einschnüren des Strömungsquerschnitts führt. Unter ungünstigen Leitungsbedingungen kann es zu vollständigen Blockaden einzelner Leitungsabschnitte kommen. Aus diesem Grund werden an diesen Punkten Entlüftungseinrichtungen eingebaut. Diese Vorrichtungen sind aufwändig, zumal sie abhängig vom Betrieb des Druckleitungsrohres automatisch funktionieren müssen. Das Einblasen von Sauerstoff in das Abwasser zum Erhalt des aeroben Zustandes ist zwar möglich, in der Abwasserdruckleitung tritt aber infolge von zum Beispiel Temperaturunterschieden der gelöste Sauerstoff aus und führt an Hochpunkten ebenfalls zu ungünstigen Leitungsbedingungen.The Movement of air in sewage pressure pipelines is caused by the roughness the pipeline, as well as the flow velocity and the inclination angle of the line. The free movement smaller air bubbles usually ends at hydraulic high points or intermediate high points. There, small bubbles accumulate too larger air accumulations, what a constriction of the flow cross section leads. Under unfavorable Conduction conditions can lead to complete blockages of individual Line sections come. That's why at these points vents built-in. These devices are complex, especially as they depend on Operation of the pressure pipe must work automatically. The Injecting oxygen into the wastewater to maintain the aerobic Condition is possible, though the waste water pressure line but occurs as a result of, for example, temperature differences the dissolved oxygen out and leads at high points also unfavorable Line conditions.
In der Praxis werden derzeit an Verlegungshochpunkten eines Druckleitungsrohres Ent- und Belüftungsvorrichtungen eingebaut, die das Luftpolster in diesem Bereich entlüften und damit auch für eine gewisse Luftzufuhr sorgen. Diese Vorrichtungen sind aufwändig, zumal sie abhängig vom Betrieb des Druckleitungsrohres automatisch funktionieren müssen.In The practice is currently at relocation high points of a pressure pipe Deaeration and ventilation devices installed, which vent the air cushion in this area and with it also for provide a certain amount of air. These devices are expensive, especially they are dependent must operate automatically from the operation of the pressure pipe.

Aufgabe der vorliegenden Erfindung ist es deshalb, Druckleitungsrohre für Flüssigkeiten der eingangs genannten Art zu schaffen, die in schneller und einfacher Weise in bereits verlegtem Zustand mit derartigen Erhebungen versehen werden können.task Therefore, it is the present invention to provide pressure pipe for liquids to create the type mentioned in the faster and easier Way in already laid state provided with such surveys can be.
Zur Lösung dieser Aufgabe sind bei einem Druckleitungsrohr der genannten Art die im Anspruch 1 angegebenen Merkmale vorgesehen.to solution This object is achieved with a pressure pipe of the type mentioned provided in claim 1 features.
Mit den erfindungsgemäßen Maßnahmen wird das zu sanierende Druckleitungsrohr bei diesem Sanierungsprozess mit entsprechenden stetig wendelförmig verlaufenden Erhebungen versehen, und zwar mittels eines mit dem oder den entsprechenden stetig wendelförmig verlaufenden Erhebungen versehenen Inliners, indem er gegen die Innenwand des zu sanierdenden Rohres gedrückt und dort verklebt wird. Dies ist im Endzustand linerinnenseitig, wobei die Erhebung zwischen Rohrinnenwandung gebracht ist, so dass sich diese Erhebungen an der Inlinerinnenwandung abzeichnen. Hierzu wird der Inliner mit der Erhebung zunächst innenseitig versehen und dann die so am Inliner angeordnete Erhebung durch Umstülpen des Inliners beim Einbringen in das zu sanierende Rohr zwischen Inlineraußenwandung und Rohrinnenwandung gebracht. Damit wird die ansonsten ”chaotische” Strömung des Abwassers innerhalb eines innenumfangsseitig glatten Rohres, bei der, wie erwähnt, die Luft nur mitgezogen wird, zu einer Drallströmung geformt, die zumindest mittig eine wesentlich höhere Strömungsgeschwindigkeit aufweist und die die sich im Rohr befindende Luft einschlägt und sich mit ihr vermischt, so dass im Wesentlichen der gesamte Abwasserstrom in dem Druckleitungsrohr in einem aeroben, dass heißt frischen und sauerstoffreichen Zustand verbleibt und in diesem Zustand der Kläranlage zugeführt wird. Derartige stetig wendelförmig verlaufende und radial nach innen vorstehende Erhebungen können nicht nur bei Druckleitungsrohren von Frischwasser angewendet werden, um Ablagerungen von Kalk, Schwebstoffen und dergleichen in den Rohrleitungssystemen zu vermeiden, sondern auch bei Druckleitungsrohren, die für den Ferntransport von Öl verwendet werden, wobei ein Absetzen der im Öl zahlreich vorhandenen Schwebstoffen während des Transports vermieden oder zumindest eingedämmt ist, sowie gemäß den Merkmalen des Anspruchs 6 bei Abwasser.With the measures according to the invention will the pressure pipe to be rehabilitated in this rehabilitation process with corresponding constantly helically extending elevations provided, by means of one with the or the corresponding continuously helically running surveys provided Inliners by against the Inner wall of the pipe to be rehabilitated is pressed and glued there. This is in the final state linerinnenseitig, the survey between Pipe inner wall is brought, so that these surveys sign off the inliner wall. For this purpose, the inliner with the Survey first provided on the inside and then arranged on the inliner survey by everting of the liner during insertion into the pipe to be rehabilitated between Inlineraußenwandung and tube inner wall brought. Thus, the otherwise "chaotic" flow of the Wastewater within an inner peripheral side smooth tube, at the, as mentioned, the air is only pulled along, formed into a swirling flow, at least in the middle a much higher one flow rate and which the air in the tube is and turns mixed with it, leaving essentially the entire sewage stream in the pressure pipe in an aerobic, that is fresh and oxygen-rich state remains and in this state the sewage plant supplied becomes. Such constantly helical extending and radially inwardly projecting elevations can not only be used with pressure pipes of fresh water to Deposits of lime, particulate matter and the like in the piping systems to avoid, but also in pressure pipe, which is for long-distance transport used by oil be, with a settling of the numerous suspended in the oil suspended matter while the transport is avoided or at least contained, and according to the characteristics of claim 6 in wastewater.
Zur Erhöhung der Drallströmung der betreffenden Flüssigkeit ist es zweckmäßig, die Maßnahmen gemäß Anspruch 2 vorzusehen.to increase the swirl flow the liquid in question it is appropriate, the activities according to claim 2 provide.
