Description
Verfahren zum Verlegen von isolierten Fernheizleitungen und Einrichtung und Muffenverbindung zur Durchführung dieses Verfahrens Die Erfindung geht aus von einem Verfahren zum Verlegen von Fernheizleitungen, bei denen der glatte Heizleitungsstrang von einer Isolierung und einem Mantelrohrstrang umgeben ist, wobei zunächst die gesamte Isolierung in die Mantelrohre eingebracht wird.Procedure for laying insulated district heating pipes and equipment and socket connection for carrying out this method. The invention is based on a method for laying district heating cables, in which the smooth heating cable strand is surrounded by insulation and a casing pipe string, initially the entire insulation is introduced into the casing pipes.
Bei diesen bekannten Verfahren werden die Mantelrohre aus zwei Halbschalen gebildet, in welche jeweils eine Isolierungsmasse eingebracht ist. Diese Halbschalen müssen an Ort und Stelle bei der bereits verlegten Rohrleitung in schwieriger Weise angebracht werden. Eine Halbschale kann dabei unter die Rohrleitung untergelegt und die andere Halbschale daraufgelegt werden, wobei das nächste in der gleichen Weise um den Heizleitungsstrang zusammengefügte Mantelrohr um ein kurzes axiales Stück verschoben wird, so daß das Spitzende dieses Mantelrohres in das Muffenende des vorherigen Mantelrohres eingreift.In this known method, the jacket pipes are made of two half-shells formed, in each of which an insulation compound is introduced. These half-shells have to be in place with the pipeline already laid in a difficult manner be attached. A half-shell can be placed under the pipeline and the other half-shell are placed on top, with the next in the same Way around the heating cable strand joined together jacket pipe around a short axial Piece is moved so that the spigot end of this jacket pipe into the socket end of the previous jacket pipe engages.
Bei Isolierungen von Dampfrohren ist es bereits bekanntgeworden, Kupplungsmuffen, die Distanzringe enthalten, zu benutzen, um Mantelrohrteile auf die Isolierung auf dem Rohr aufzubringen.When it comes to the insulation of steam pipes, it has already become known to use coupling sleeves, The spacer rings included, to be used to place jacket pipe parts on the insulation to apply to the pipe.
Die Aufgabe der Erfindung besteht gegenüber diesem Bekannten darin, Verfahren der im ersten Absatz dieser Beschreibung genannten Art insoweit zu verbessern, daß eine rationellere Verlegungsweise erreicht wird.The object of the invention is towards this known person is To improve procedures of the type mentioned in the first paragraph of this description, that a more rational way of laying is achieved.
Zur Lösung dieser Aufgabe ist die Vereinigung folgender Merkmale vorgesehen: a) Mehrere Mantelrohre werden unter Verwendung von an sich bekannten Kupplungsmuffen, welche gleichfalls an sich bekannte Distanzringe enthalten, zu einem Mantelrohrstrang verbunden.To solve this problem, the combination of the following features is provided: a) Several casing pipes are connected using coupling sleeves known per se, which also contain spacer rings known per se, to form a casing pipe string tied together.
b) An dem vorderen Ende des Heizleitungsstranges wird ein konisch verlaufender Führungsdorn eingesetzt.b) At the front end of the heating cable strand, a becomes conical running guide pin used.
c) Der Heizleitungsstrang wird in den Mantelrohrstrang eingeschoben oder eingezogen.c) The heating cable is pushed into the casing pipe or drafted.
Weitere für die Aufgabenlösung vorteilhafte und förderliche Weiterbildungen sind den am Schluß der Beschreibung angeführten Unteransprüchen 2 bis 6 zu entnehmen.Further training that is advantageous and conducive to solving the problem can be found in the subclaims 2 to 6 listed at the end of the description.
Durch die Erfindung wird insofern ein technischer Fortschritt erreicht, als bei Verfahren der im ersten Absatz dieser Beschreibung dargestellten Art eine rationellere Verlegungsweise erreicht wird. Außerdem ist bei der Erfindung vermieden, daß ungeschützte Leitungsrohre im Rohrgraben vor dem überschieben der einzelnen Schutzrohre den Einflüssen der Grabenfeuchtigkeit u. dgl. ausgesetzt sind. Die Erfindung wird an Hand eines Ausführungsbeispieles in der Zeichnung näher erläutert. Hierbei zeigt F i g. 1 einen durch das Verfahren verlegten Fernheizleitungsabschnitt, F i g. 2 eine Muffenverbindung im vergrößerten Maßstab, F i g. 3 eine andere Muffenverbindung und F i g. 4 das vordere Ende des Fernheizleitungsstranges mit einem aufgesetzten Führungsdorn.The invention achieves a technical advance, than in the case of methods of the type set out in the first paragraph of this description a more rational way of laying is achieved. In addition, the invention avoids that unprotected pipes in the pipe trench before pushing over the individual Protective pipes are exposed to the effects of trench moisture and the like. The invention is explained in more detail using an exemplary embodiment in the drawing. Here shows Fig. 1 a district heating line section laid by the method, F i g. 2 shows a socket connection on an enlarged scale, FIG. 3 another socket connection and F i g. 4 the front end of the district heating line with an attached one Guide mandrel.
Aus der Zeichnung, insbesondere F i g. 1, ist zu ersehen, wie bei Fernheizleitungen, die mit dem Verfahren verlegt sind, der glatte Heizungsstrang von einer Isolierung 3 und einem Mantelrohrstrang 1 umgeben ist. Hierbei wird zunächst die gesamte Isolierung 3 in die Mantelrohre 1 eingebracht. Dies kann schon vorfabrikatorisch in Werkstätten geschehen. An der Baustelle werden dann mehrere Mantelrohre 1 unter Verwendung von Kupplungsmuffen 4, die Distanzringe 7 enthalten, zu einem Mantelrohrstrang verbunden. Danach wird an dem vorderen Ende des Heizleitungsstranges 2 ein konisch verlaufender Führungsdorn 9 eingesetzt. Hiernach wird der Heizleitungsstrang 2 in den Mantelrohrstrang 1 eingeschoben oder eingezogen. Der Führungsdorn 9 kann in einem am vorderen Ende des Heizleitungsstranges 2 eingesetzten Haltering 11 winkelbeweglich angeordnet sein. Er kann fernerhin länger als ein Mantelrohr 1 sein. Fernerhin kann vorgesehen sein, daß die Innenfläche der Distanzringe 7 nach einer oder nach beiden Seiten trichterförmig erweitert ist. Die Kupplungsmuffe 4 kann einseitig mit dem Ende des einen Mantelrohres 1 fest verbunden sein, wobei auch der Distanzring 7 stirnseitig am Mantelrohr sowie an seinem Umfang in der Kupplungsmuffe 4 fest verbunden ist. Das andere Ende der Kupplungsmuffe 4 dient dann unter Zwischenschaltung einer oder mehrerer Distanzdichtungen 5, 6 zur Aufnahme des anderen Mantelrohres 1. Die Kupplungsmuffe 4 kann beidendig zum Einschieben der Mantelrohre 1 eingerichtet sein, wobei der Distanzring 7 nur auf seinem Umfang fest mit der Kupplungsmuffe verbunden ist.From the drawing, in particular FIG. 1, it can be seen how, in the case of district heating lines that are laid using the method, the smooth heating line is surrounded by insulation 3 and a casing pipe line 1. Here, the entire insulation 3 is first introduced into the casing pipes 1. This can be done prefabrication in workshops. At the construction site, several casing pipes 1 are then connected to form a casing pipe string using coupling sleeves 4 which contain spacer rings 7. Thereafter, a conical guide mandrel 9 is inserted at the front end of the heating line strand 2. Thereafter, the heating cable 2 is pushed into the casing pipe 1 or pulled. The guide mandrel 9 can be arranged in an angularly movable manner in a retaining ring 11 inserted at the front end of the heating line strand 2. It can also be longer than a jacket tube 1 . Furthermore, it can be provided that the inner surface of the spacer rings 7 is widened in a funnel shape on one or both sides. The coupling sleeve 4 can be firmly connected on one side to the end of the one casing pipe 1, the spacer ring 7 also being firmly connected to the casing pipe on the front side and on its circumference in the coupling sleeve 4. The other end of the coupling sleeve 4 is then used, with the interposition of one or more spacer seals 5, 6, to accommodate the other casing pipe 1. The coupling sleeve 4 can be set up at both ends for inserting the casing pipes 1, the spacer ring 7 only being firmly connected to the coupling sleeve on its circumference is.
