Description

Verfahren zum Nachformen von Rohren aus thermoplastischen Stoffen Die Erfindung bezieht sich auf Rohre aus thermoplastischen Stoffen, wie sie in neulerer Zeit, z. B. in größerem Maße, zulm Einziehen elektrischer Leitungen als Ersatz der bisher jiblichen verbleiten Isolierrohre verwendet werden. Bei derartigen Rohren lassen sich im allgemeinen heim Aufwickeln auf Trommeln oder bei der Verlegung in Gräben Verformungen nicht vermeiden. Besonders bei Rohren größerer Abmessungen mit einer lichten Weite von 50 min und mehr ist die Gefahr derartiger Verformungen besonders groß.Process for reshaping pipes made of thermoplastic materials The invention relates to pipes made of thermoplastic materials such as those in neulerer Time, e.g. B. to a larger extent, allow the pulling in of electrical cables as a replacement for the up to now common leaded insulating tubes are used. With such pipes can generally be used for winding on drums or for laying in Do not avoid trenches from deformation. Especially with pipes of larger dimensions with With a clear width of 50 min and more, the risk of such deformations is particular great.

Um nun die Leitung ungehindert in die verlegten Rohrleitungen leinziehlen zu können, ist es erforderlich, die Eindrückungen oder breitgedrückten Stellen, die besonders im Summer bei wärmerer Temperatur auftreten können, vor der endgültigen Verwendung der Rohre für den beabsichtigten Zweck wieder nmd zu richten.In order to now draw the line unhindered into the laid pipelines to be able to, it is necessary to remove the indentations or broadly pressed areas which can occur especially in summer when the temperature is warmer, before the final Use the tubes for the intended purpose again to direct nmd.

Das Nachformen derartiger Rohre geschieht gemäß der Erfindung m der Weise, daß durch sie, insbesondere nach ihrer endgültigen Verllegung, ein durch einen einglebauten elektrischen Heizkörper beheizter zylinderförmiger Körper gezogen wird, dessen Außendurchmesser dem lichten Durchmesser der Rohre entspridit. The reshaping of such tubes is done according to the invention m the Way that through them, especially after their final relocation, a through a built-in electric radiator heated cylindrical body drawn whose outside diameter corresponds to the inside diameter of the pipes.

In der Zeichnung ist das Verfahren gemäß der Erfindung näher erläutert. Der Kunststoftraantel 1, der aus einer oder mehreren Lagen von thermoplastischen Stoffen bestehen kann, besitzt Eindrückungen und Verformungen 2, die während der Verlegung entstanden sind. Durch das Rohr wird nun nach der Erfindung ein torpedoförmiger Körper 3 gezogen, der in seinem Innern eine Heizwicklung 4 besitzt. Der Zug wird ausgeübt mittels des Zugseiles 5, das in seinem Innern Adern zur Zuführung des elektrischen Stromes für die Heizwicklung 4 besitzt. Das Stahlseil 5 ist mit dem Körper 3 mittels einer öse6 verbunden. Der Körper 3 besitzt außerdem eine Zugöse 7, an der ein Seil 8 zur Einziehung der Leitung befestigt sein kann. Die Temperatur in dem Zugkörper 3 kann durch Versuche festgestellt werden. Vorteilhafter ist es, mit dem torpedoförmigen Körper 3 ein entsprechend geschützties Taemperaturanzeigeinstrument durch das Rohr zu ziehen, wobei durch eine Temperaturmeßleitung vom Rohrende aus die Temperatur gemessen werden kann. Das Fortschreiten des Zugkörpers 3 im thermoplastischen Rohr läßt sich im allgemeinen von außen beobachten, so daß eine Kühlung von außen unmittelbar nach dem Durchziehen des Zugkörpers möglich ist. The method according to the invention is explained in more detail in the drawing. The Kunststoftraantel 1, which consists of one or more layers of thermoplastic Substances can exist, has indentations and deformations 2 that occur during the Relocation have arisen. According to the invention, the tube now becomes a torpedo-shaped one Body 3 drawn, which has a heating coil 4 in its interior. The train will exercised by means of the pull rope 5, which has veins in its interior for supplying the electrical Current for the heating coil 4 has. The steel cable 5 is with the body 3 by means connected to an eyelet6. The body 3 also has a towing eye 7 on which a rope 8 can be attached to the collection of the line. The temperature in the tensile body 3 can be determined through experiments. It is more advantageous to use the torpedo-shaped one Body 3 a correspondingly protected dew temperature display instrument through the tube to pull, with the temperature through a temperature measuring line from the end of the pipe can be measured. The progression of the tensile body 3 in the thermoplastic pipe can generally be observed from the outside, so that cooling from the outside is immediate after pulling through the pulling body is possible.

Das Verfahren gemäß der Erfindung ist für sämtliche Rohre oder rohrähnliche Körper aus thermoplastischen Stoffen geeignet und kann sowohl für Rohre zum Einziehen von Leitungen als auch für solche zum Fort leiten von Fliiszigkeiten verwendet werden. The method according to the invention is for all pipes or pipe-like ones Body made of thermoplastic materials suitable and can be used for both pipes for pulling of lines as well as those used for the forwarding of liquids.
