Abstract
Description
Die Erfindung betrifft ein Verfahren zum Sanieren von begehbaren Abwasserkanälen nach dem Rohrrelining-Verfahren, bei welchem in den zu sanierenden Abwasserkanal stückweise ein neues Hauptrohr, vorzugsweise aus glasfaserverstärktem Kunststoff (GFK) eingeschoben wird. Dabei entsteht zwischen dem neuen Hauptrohr und dem Altkanal ein hohler Ringraum, welcher durch Verdämmen mit Flüssigbeton verfüllt wird.The invention relates to a method for rehabilitating walk-in sewers after the pipe relining method, in which in the sewer to be rehabilitated piecewise a new main pipe, preferably made of glass fiber reinforced plastic (GRP) is inserted. This creates between the new main pipe and the old channel a hollow annulus, which is filled by damding with liquid concrete.
Beim so genannten Rohrinlining-Verfahren, bei dem im Altkanal eine an dessen Innenwandung anliegende Auskleidung erzeugt wird, entsteht ein solcher zu verdämmender Ringraum nicht.In the so-called pipe lining method, in which a lining resting against its inner wall is produced in the old channel, such an annular space to be dammed does not arise.
Stand der TechnikState of the art
Ein Problem bei diesen Sanierungsverfahren besteht darin, die in den alten Abwasserkanal mündenden Anschlussrohre, zum Beispiel die einzelnen Hausanschlüsse, in das neue Hauptrohr einzubinden. Während der Bauphase, insbesondere beim Verdämmen des Ringraumes zwischen dem Altkanal und dem neuen Hauptrohr, kommt es häufig zu Undichtigkeiten an der Einbindungsstelle, da diese in der Regel nicht elastisch genug ausgebildet ist.One problem with these remediation methods is that the connecting pipes opening into the old sewer, for example the individual service connections, are integrated into the new main pipe. During the construction phase, especially when damaging the annulus between the old channel and the new main pipe, there are often leaks at the point of integration, since this is not formed elastic enough in the rule.
Speziell für die Sanierung von Abwasserkanälen nach dem Rohrinlining-Verfahren sind unterschiedliche Lösungen bekannt, bei denen ein neues Anschlussrohr mündungsseitig mit einem sattelförmigen Rand versehen ist, welcher an der Innenwand der neuen Kanalauskleidung dichtend befestigt wird (
Um den Raum zwischen dem Altkanal und dem neuem Hauptrohr zu überblicken wurde auch mehrfach vorgeschlagen, aufweitbare Verbindungsrohe einzusetzen, welche sich zumindest im vorhanden Anschlussrohr dichtend an dieses anlegen (
Aus
Es ist Aufgabe der Erfindungen ein Verfahren und eine Anordnung speziell zum Sanieren von Abwasserkanälen nach dem Rohrrelining-Verfahren zu schaffen, mit welchen kostengünstig und technologisch einfach der Anschluss vorhandener Zulaufrohre an das neue Hauptrohr möglich ist, wobei insbesondere beim Verdämmen des Ringraumes zwischen dem Altkanal und dem neuen Hauptrohr auftretende Lageveränderungen und Verformungen an der Einbindungsstelle kompensiert werden können.It is an object of the invention to provide a method and an arrangement specifically for rehabilitating sewers according to the Rohrrelining method, which cost and technologically simple connection of existing feed pipes to the new main pipe is possible, in particular when daming the annulus between the old channel and the new main pipe occurring position changes and deformations can be compensated at the point of integration.
Diese Aufgabe wird durch ein Verfahren und eine Anordnung nach den Patentansprüchen 1 und 3 gelöst. Vorteilhafte Ausgestaltungen der Erfindungen sind in den Unteransprüchen angegeben.This object is achieved by a method and an arrangement according to
Die erfindungsgemäßen Vorteile bestehen darin, dass während der Bauphase auftretende Lageveränderungen und Verformungen des neuen Hauptrohres durch die gelenkige Anordnung des Anschlussrohres kompensiert werden. Dadurch können keine Beschädigungen und Undichtigkeiten an der Einbindungsstelle mehr auftreten.The advantages of the invention are that during the construction phase occurring changes in position and deformations of the new main pipe are compensated by the articulated arrangement of the connecting pipe. As a result, no damage and leaks at the point of integration can occur more.
Vorteilhaft ist weiterhin, dass die Verbindung zwischen dem altem Zulaufrohr und dem in den neuen Hauptrohr mündenden neuen Anschlussrohr schon vor dem Verdämmen des Ringraumes absolut dicht ausgeführt wird. Dadurch ist eine Ableitung von Abwasser schon vor dem Verdämmen des Ringraumes möglich, ohne dass Abwasser während der Bauphase in den Ringraum gelangt.A further advantage is that the connection between the old inlet pipe and the opening into the new main pipe new connection pipe is made absolutely tight even before the dam of the annulus. As a result, a discharge of wastewater before the damding of the annulus is possible without wastewater entering the annulus during the construction phase.
Die Lagerung des Anschlussrohres in einer Ringdichtung im durchmesservergrößerten Teil der Verbindungshülse ermöglicht die notwenige Schwenkbarkeit des Anschlussrohres und die Realisierung eines für den ordnungsgemäßen Abfluss ausreichend großen Querschnitts des Anschlussrohres.The mounting of the connection pipe in a ring seal in enlarged diameter part of the connection sleeve allows the necessary pivotability of the connection pipe and the realization of a sufficiently large for proper drainage cross-section of the connection pipe.
