Description
Verfahren zum Auskleiden von Rohren Es ist bekannt, die Innengummierung von Rohren durch Anbügeln des Rohgummis mittels massiver Stopfen, die durch das Innere der Rohre gezogen werden, vorzunehmen.Process for lining pipes It is known the internal rubber lining of pipes by ironing on the raw rubber using massive plugs, which are inserted through the Inside of the pipes are pulled to make.
Als solche Stopfen verwendet man z. B. Eisenkerne mit Weichgummiüberzug oder Vollgummikörper. Bei Anwendung dieses Arbeitsverfahrens ist es aber von Nachteil, daß für jeden Rohrdurchmesser ein besonderer Stopfen bereit gehalten werden muß und daß eine Innengummierung von Rohrbögen, insbesondere solchen mit kleinem Radius, nur sehr schwierig und zudem nicht einwandfrei gelingt.Such a stopper is used, for. B. Iron cores with soft rubber coating or solid rubber body. When using this working method, however, it is disadvantageous that a special plug must be kept ready for each pipe diameter and that an inner rubber lining of pipe bends, especially those with a small radius, only very difficult and, moreover, not perfectly successful.
Bei Rohrbögen mit längeren Schenkeln ist dieses Verfahren nur dann möglich, wehneine Unterteilung der Bögen durch Flanschen vorgenommen wird. Zur Innengummierung von Rohrbögen mit Querschnittsänderungen und konischen Rohrteilen ist die Anwendung von massiven Stopfen überhaupt nicht möglich. In diesem Falle muß man zu dem primitiven und unzuverlässigen Ankratzen mit langen Stangen greifen. In the case of pipe bends with longer legs, this procedure is only applicable possible if the arches are subdivided by flanges. For inner rubber lining of pipe bends with changes in cross section and conical pipe parts is the application not possible at all from massive stoppers. In this case one has to go to the primitive one and unreliable scratching with long poles.
Man hat zum Auskleiden von gebogenen Hohlkörpern auch schon vorgeschlagen, in eine zunächst außerhalb des Rohres fertiggestellte Rohrauskleidung einen Gummischlauch einzuführen, diesen nur so weit aufzublasen, daß die Auskleidung mit dem aufgeblasenen Gummischlauch in Berührung kommt, und dann die Auskleidung mitsamt dem leicht aufgeblasenen Schlauch in das auszukleidende Rohr einzuführen, nachdem Auskleidungsmasse und Rohr mit Iebstoff versehen sind. It has already been proposed to line curved hollow bodies, a rubber hose into a pipe lining that was initially completed outside the pipe to introduce, inflate this only so far that the lining with the inflated Rubber hose comes into contact, and then the liner together with the slightly inflated Insert hose into the pipe to be lined, after lining compound and pipe are provided with adhesive.
Wenn Auskleidung und Gummischlauch in das Rohr ganz eingeführt worden sind, wird der Gummischlauch stark aufgeblasen und dadurch die Auskleidung an die Rohrinnenwand angepreßt. When the liner and rubber hose have been fully inserted into the pipe the rubber hose is inflated strongly and thereby the lining to the Inner pipe wall pressed on.
Da die Anpressung überall gleichzeitig erfolgt, können vorhandene Luftblasen zwischen Rohr und Auskleidung nicht entweichen, d. h. es besteht die Gefahr, daß an manchen Stellen luftgefüllte Beulen zurückbleiben. Since the pressing takes place everywhere at the same time, existing Air bubbles do not escape between the pipe and the liner, d. H. there is the There is a risk that air-filled bumps will remain in some places.
Diese Nachteile werden nun erfindungsgemäß dadurch vermieden, daß das Auskleiden von Rohren aller Art mit Hilfe eines aufbiähbaren Hohlkörpers, der die Auskleidung an die Rohrinnenwand anpreßt, in der Weise geschieht, daß der stark aufgeblähte, elastische Hohlkörper durch das Rohr hindurchgezogen wird, In der beiliegenden Zeichnung sind Ausführungsformen des Verfahrens beispielsweise dargestellt. Fig. I zeigt die Innengummierung eines geraden Rohres mittels eines durch Innendruck aufblähbaren Hohlkörpers aus Weichgummi, Fig. 2 die Ausübung der Innengummierung eines Rohres mit Querschnittsveränderung und anschließendem Rohrbogen. These disadvantages are now avoided according to the invention in that the lining of pipes of all kinds with the help of an expandable hollow body, the the lining presses against the pipe inner wall, in such a way that the strong inflated, elastic hollow body is pulled through the tube, in the enclosed Embodiments of the method are shown, for example, in the drawing. Fig. I shows the internal rubber lining of a straight pipe by means of an internal pressure inflatable hollow body made of soft rubber, Fig. 2 the exercise of the inner rubber lining of a pipe with a change in cross-section and a subsequent pipe bend.
Der Gummihohlkörper 1 wird in aufgeblähtem Zustande mittels geeigneter Zugorgane 2, die an beiden Enden oder nur an einem Ende des Körpers befestigt werden, durch das mit Rohgummifellen 3 belegte Innere des Rohres 4 hindurchgezogen. The hollow rubber body 1 is inflated by means of suitable Traction organs 2, which are attached at both ends or only at one end of the body, pulled through the interior of the tube 4, which is covered with raw rubber skins 3.
