Abstract

In the event where their use value has been reduced, e.g. by cracks or lime deposits, sewers in which it is not possible to walk have, up until now, had to be excavated from above in order to repair them. In order to avoid this expensive process, new pipes are to be drawn into the old sewers in accordance with a more recent process. The production of service connections in a new pipe cannot be carried out neatly by means of known robot vehicles because the position and angle of the relative service connection in the new pipe can no longer be established. The novel process is to permit accurate production of service connections and other line connections in the new pipe. A vehicle (1) moves up to the location of the respective connection in the sewer (15) which is to be repaired, and stores the coordinates of the connection. After the new pipe has been drawn in, the vehicle (1) automatically moves up to the connection, corresponding to the stored data, and produces the new connection. The vehicle (1) comprises, inter alia, a milling cutter, which can move along a circular or elliptical path, and a platform which is pivotably mounted on the vehicle. The process and the apparatus permit accurate production of line connections in the newly drawn-in pipe without having to excavate the sewer, in which it is not possible to walk, from above. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Vermessung vorhandener Anschlüsse an einem Kanal und Anbringung neuer Anschlüsse an jeweils gleicher Stelle an ein in den Kanal eingezogenes Innenrohr, mit Hilfe eines selbstfahrenden Fahrzeugs, das mit Meß-, Beleuchtungs- und Arbeitseinrichtungen versehen ist.The invention relates to a method and a Device for measuring existing connections on one Channel and attaching new connections to the same Place on an inner tube drawn into the duct, with With the help of a self-driving vehicle equipped with measuring, Lighting and work facilities is provided.

Durch Risse, Wurzeleinwüchse, Kalkablagerungen und andere Enwirkungen in ihrem Gebrauchswert geminderte Kanäle müssen saniert werden. Nicht begehbare Kanäle müssen hierzu von oben her aufgegraben und ersetzt werden. Dieses Verfahren ist aber teuer, zeitraubend und mit Behinderungen im Straßenverkehr verbunden. Es ist bekannt, in alte Kanäle in einem "Reliningverfahren" neue Innenrohre einzuziehen. Durch das Einziehen der neuen Innenrohre werden aber bestehende Kanalanschlüsse, also insbesondere Hausanschlüsse, verschlossen. Zur Herstellung der Kanalanschlüsse an dem neuen Innenrohr ist der Einsatz ferngesteuerter Roboterfahrzeuge bekannt, die in dem neuen Innenrohr jeweils die Stelle anfahren müssen, an der der betreffende Kanalanschluß anzubringen ist. Die Roboterfahrzeuge sind mit einer Kamera bestückt, die eine Überwachung der Arbeiten über einen Monitor erlaubt. Der Nachteil des bekannten Systems besteht aber darin, daß es dem Roboterfahrzeug unmöglich ist, in dem neuen Innenrohr die Stelle zu finden, an der der alte Kanal- oder Hausanschluß sitzt, an der also der neue Anschluß an dem neuen Innenrohr anzubringen ist, denn das neue Innenrohr macht das Roboterfahrzeug hinsichtlich der Lage des neuen Anschlusses "blind".Through cracks, root ingrowth, limescale deposits and others Effects in channels reduced in use value need to be renovated. Channels that cannot be walked on are dug up and replaced from above. This However, the process is expensive, time-consuming and expensive Disabilities associated with road traffic. It is known, into old channels in a "relining process" new Pull in inner tubes. By pulling in the new one Inner pipes become existing sewer connections, so especially house connections, closed. For the production the channel connections on the new inner tube is the insert remote-controlled robot vehicles known in the new Inner tube must approach the point where the relevant duct connection is to be attached. The Robot vehicles are equipped with a camera, the one Monitoring of the work on a monitor allowed. The The disadvantage of the known system is that it the robot vehicle is impossible in the new inner tube to find the place where the old canal or House connection sits, so the new connection on the new inner tube is to be attached, because the new inner tube makes the robot vehicle with regard to the location of the new one "Blind" connection.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Durchführung des Verfahrens zu schaffen, mit denen binnen kurzer Zeit Anschlüsse an einem neuen Innenrohr anbringbar sind, die in ihrer Lage und ihren Winkeln exakt den alten Anschlüssen entsprechen.The invention has for its object a method and an apparatus for performing the method create connections with you within a short time  new inner tube are attachable in their position and their angles correspond exactly to the old connections.

Erfindungsgemäß wird die Aufgabe durch die im Kennzeichen des Anspruchs 1 aufgeführten Merkmale gelöst.According to the invention, the object is characterized by the of the features listed solved.

Die Erfindung weist gegenüber dem Bekannten die Vorteile auf, daß rasch und sehr sicher die erforderlichen Anschlüsse, insbesondere Hausanschlüsse, an einem neuen Innenrohr anbringbar sind. Ein Suchen nach der Stelle, an der der betreffende Anschluß angebracht werden muß, erübrigt sich. Hierdurch kann wertvolle Zeit eingespart werden, während der eine teure Roboteranlage eingesetzt werden muß. Die neuen Anschlüsse an dem neuen Innenrohr entsprechen hinsichtlich ihres Ortes und Winkels exakt den Anschlüssen in dem alten Kanal.The invention has the advantages over the known on that quickly and very surely the necessary Connections, especially house connections, to a new one Inner tube are attachable. A search for the job at the connector in question must be attached, is unnecessary. This can save valuable time are used during the an expensive robotic system must become. The new connections on the new inner tube correspond exactly to their location and angle Connections in the old channel.
