Description

Die Deregulierung des Telekommunikationsmarktes in Deutschland, sowie die rasch steigenden An­ forderungen an die Übertragungskapazitäten erfordern die Neuverlegung von Datenleitungen, vor­ zugsweise von Lichtwellenleitern.The deregulation of the telecommunications market in Germany, as well as the rapidly increasing number Requirements for the transmission capacities require the relocation of data lines preferably of optical fibers.

Ebenso gibt es einen stetig wachsenden Bedarf, bereits verlegte Rohrleitungsnetze, vor allem Trink­ wasserleitungen zu sanieren, da diese im Laufe der Zeit und durch die zunehmende Aggressivität des Trinkwassers Durchrostungungen und andere Undichtigkeiten aufweisen.There is also a steadily growing need, already installed pipeline networks, especially drinking Water pipes to be renovated, as they grow over time and through increasing aggressiveness rust and other leaks in the drinking water.

Es wird vorgeschlagen, Datenleitungen in bestehende Rohrleitungen einzubringen, also vor allem in Trinkwasserleitungen, Gasleitungen und nicht begehbare Abwasserleitungen. Dieses Vorgehen kombiniert die Lösung beider Aufgabenstellungen und ist somit wirtschaftlich sinn­ voll und, durch die weitgehende Vermeidung von Erdarbeiten auch konkurrenzfähig gegenüber anderen Verfahren zur Erneuerung, bzw. Verlegung von Rohr- und Datenleitungen.It is proposed to insert data lines in existing pipelines, especially in Drinking water pipes, gas pipes and non-accessible sewage pipes. This procedure combines the solution of both tasks and is therefore economically sensible full and, by largely avoiding earthworks, also competitive with other procedures for the renewal or laying of pipe and data lines.

Es sind verschiedene Verfahren bekannt, bereits verlegte Rohrleitungen mit einer Innenauskleidung zu versehen, um Undichtigkeiten zu beseitigen, oder um Korrosionsschäden und das Auswaschen von Oxiden und anderen Verunreinigungen aus z. B. Trinkwasserleitungen zu verhindern, die vorlie­ gende Erfindung beschreibt die Anordnung von Leitungen für die Datenübertragung, vor allem von Lichtwellenleitern für die Telekommunikation in der Wandung von solchen Innenauskleidungen.Various methods are known, already installed pipelines with an inner lining to remove leaks or to prevent corrosion and washing out of oxides and other impurities from e.g. B. to prevent drinking water pipes, which existed The present invention describes the arrangement of lines for data transmission, especially of Optical fibers for telecommunications in the wall of such inner linings.

Im Folgenden werden die bekannten Verfahren zur Innenauskleidung von Rohrleitungen und zur Verlegung von Datenleitungen in bestehenden Rohrleitungen genannt.In the following, the known methods for the inner lining of pipes and for Laying of data lines in existing pipelines.

Die DE 298 01 408 U1 beschreibt eine Vorrichtung zum Fixieren eines Kabels, insbesondere eines optischen Kabels an der Innenwand eines nicht begehbaren Abwasserrohres mittels einer Wendel aus federndem Material, die im entspannten Zustand das Kabel gegen die Innenwand drückt.DE 298 01 408 U1 describes a device for fixing a cable, in particular one optical cable on the inner wall of a non-accessible sewage pipe using a helix Made of resilient material that, when relaxed, presses the cable against the inner wall.

Darüber hinaus lehrt die Druckschrift DE 40 27 099 A1, ein aus nachgiebigem Material bestehendes Rohr in eine Form zu bringen, deren Aussenumfang kleiner ist, als der Innenumfang des zu sanie­ renden Rohres, so dass das Einbringen des Rohres in die Rohrleitung erleichtert wird. Anschliessend wird durch das Einführen eines Mediums (z. B. heisser Dampf oder Warmluft) in das Rohrinnere die­ ses in eine Form entsprechend dem Innenumfang der Rohrleitung gebracht.In addition, the document DE 40 27 099 A1 teaches an existing flexible material To bring the pipe into a shape whose outer circumference is smaller than the inner circumference of the sanie Renden tube, so that the insertion of the tube into the pipeline is facilitated. Subsequently is achieved by introducing a medium (e.g. hot steam or warm air) into the inside of the pipe ses brought into a shape according to the inner circumference of the pipeline.

Die vorliegende Anmeldung hebt sich von DE 298 01 408 U1 dadurch ab, dass die Datenleitung zusammen mit einem Innenrohr in das zu sanierende Rohr eingebracht wird, da sie fest in dessen Wandung eingearbeitet ist. Die feste Einarbeitung hat gegenüber dem zitierten Stand der Technik den Vorteil, dass viele Lichtwellenleiter gleichmässig über den Umfang des Innenrohres in dessen Wandung verteilt werden können, und dass sie durch diese Einarbeitung bereits ausreichend gegen äussere Einflüsse geschützt und im Rohr fixiert sind.The present application stands out from DE 298 01 408 U1 in that the data line is introduced together with an inner pipe into the pipe to be renovated, since it is firmly in the pipe Wall is incorporated. The firm familiarization with the state of the art cited the advantage that many optical fibers are evenly distributed over the circumference of the inner tube Wall can be distributed, and that they are already sufficiently countered by this incorporation external influences are protected and fixed in the pipe.

Die Druckschrift DE 40 27 099 A1 zeigt, wie ein aus nachgiebigem Material bestehendes Rohr mit einem U-förmigen, reduzierten Querschnitt in ein Rohr eingebracht und dort mit Heissdampf an des­ sen Innefläche angelegt werden kann. Allerdings wird dort kein Rohr vorgeschlagen, in dessen Wandung Datenleitungen fest eingearbeitet sind.The document DE 40 27 099 A1 shows how a pipe made of a flexible material can be used a U-shaped, reduced cross-section introduced into a tube and there with hot steam at the can be created. However, no pipe is proposed there, in the Wall data lines are firmly incorporated.

Ein weiteres bekanntes Verfahren, das sogen. Phoenix-Verfahren sieht vor, dass ein Schlauch in das zu sanierende Rohr eingekrempelt wird.Another known method, the so-called. Phoenix process provides that a hose is in the pipe to be renovated is rolled up.

Um auch hier die Datenleitung zusammen mit diesem Schlauch einbringen zu können, wird vorge­ schlagen, sie in dessen Verstärkungsgewebe einzuarbeiten.In order to be able to insert the data line together with this hose here, too, is preceded suggest incorporating them into its reinforcement fabric.

Erläuterungen zu den Abbildungen:Explanations to the pictures:

Abb. 1 zeigt das bekannte U-liner Prinzip, eine U-förmige Einbuchtung des Innenrohres verringert dessen Durchmesser, wodurch es in die Rohrleitung eingezogen werden kann Fig. 1 shows the well-known U-liner principle, a U-shaped indentation of the inner tube reduces its diameter, which means that it can be drawn into the pipeline

Abb. 2 zeigt den U-liner, wie er mit Heissdampf erwärmt und an die Innenseite der Rohrleitung angepresst wird. Fig. 2 shows the U-liner how it is heated with hot steam and pressed against the inside of the pipeline.

Abb. 3 zeigt das Innenrohr und Datenleitungen, welche in seine Wandungen fest eingearbeitet sind. Fig. 3 shows the inner tube and data lines, which are built into its walls.

Abb. 4 zeigt den rohrförmigen Körper, welcher nach dem U-liner Prinzip Einbuchtungen aufweist, welche seinen Aussendurchmesser so verringern, dass er kleiner ist als der Innendurchmesser der Rohrleitung, in welche er eingezogen werden soll. Fig. 4 shows the tubular body which, according to the U-liner principle, has indentations which reduce its outside diameter so that it is smaller than the inside diameter of the pipeline into which it is to be drawn.

Die in den Abbildungen verwendeten Bezugszeichen bedeuten im einzelnen: 1 Rohrleitung
2 Innenrohr, U-liner oder anderer rohrförmiger Körper, z. B. gewebeverstärkter Schlauch
3 Innenrohr, wie es an die Innenfläche der Rohrleitung angelegt wird.
4 Datenleitung
5 rohrförmiger Körper, mit Datenleitungen und Einbuchtungen nach dem U-liner Prinzip.
The reference numerals used in the figures mean: 1 pipe
2 inner tube, U-liner or other tubular body, e.g. B. reinforced hose
3 Inner pipe as it is placed on the inner surface of the pipe.
4 data line
5 tubular body, with data lines and indentations according to the U-liner principle.
