Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Rohrverbunds aus wenigstens zwei Kunststoffrohren, welche in dem Rohrverbund etwa in Längsrichtung ausgerichtet sind, wobei wenigstens zwei einzelne benachbarte Kunststoffrohre über ein Verbundmittel aus Kunststoff verbunden sind, welches jeweils mit einem Abschnitt der äußeren Mantelfläche der Einzelrohre stoffschlüssig verbunden ist und die Einzelrohre untereinander zu einem gemeinsam handhabbaren Rohrverbund verbindet.The present invention relates to a method for producing a composite pipe from at least two plastic pipes, which are aligned in the pipe assembly approximately in the longitudinal direction, wherein at least two individual adjacent plastic pipes are connected via a composite plastic, which in each case cohesively with a portion of the outer surface of the individual tubes is connected and connects the individual tubes with each other to a jointly manageable pipe network.
Ein Rohrverbund aus mehreren Kunststoffrohren der eingangs genannten Art wird beispielsweise in der
Aus der
Da in der Praxis häufig große Längen eines solchen Rohrverbunds benötigt werden, die an der Baustelle von einer Trommel abgewickelt werden, können hohe Torsionskräfte auftreten. Auch bereits durch das Aufwickeln der Rohre werden Spannungen erzeugt, die auf die Einzelrohre einwirken. Bei einem festen Rohrverbund mit aufgeschrumpfter Deckschicht kann es durch dieses Aufwickeln zu einer unkontrollierten Verschiebung (zum Beispiel Torsion) von Abschnitten der Einzelrohre im Rohrverbund kommen, so dass die Lage der Einzelrohre im Rohrverbund nach der Herstellung von außen nicht mehr erkennbar ist. Dies ist sehr nachteilig, wenn die Rohre des Rohrverbunds als Kabelschutzrohre dienen und beispielsweise nachträglich Glasfaserkabel oder Leitungen über größere Längen in die Einzelrohre eingebracht werden müssen. Durch die Torsionen kann es zu störenden Querschnittsverengungen in den Rohren kommen, die das Einbringen der Kabel verhindern.Since in practice often large lengths of such a composite pipe are required, which are handled at the construction site of a drum, high torsional forces can occur. Even by the winding of the tubes voltages are generated, which act on the individual tubes. In the case of a solid tube composite with a shrunk-on covering layer, this winding can lead to an uncontrolled displacement (for example of torsion) of sections of the individual tubes in the tube assembly, so that the position of the individual tubes in the tube assembly can no longer be recognized from the outside after production. This is very disadvantageous if the tubes of the tube assembly serve as cable protection tubes and, for example, subsequently fiber optic cables or lines must be introduced over long lengths in the individual tubes. The torsions can lead to disturbing cross-sectional constrictions in the pipes, which prevent the introduction of the cables.
Die Aufgabe der vorliegenden Erfindung besteht darin, ein Verfahren zur Herstellung eines Rohrverbunds aus wenigstens zwei Kunststoffrohren der eingangs genannten Gattung, bei dem die Einzelrohre im Rohrverbund aus einer etwa linearen Anordnung in eine kompakte Anordnung geschwenkt werden können, im Hinblick auf eine vorteilhafte rationelle Herstellung zu verbessern.The object of the present invention is to provide a method for producing a composite pipe from at least two plastic pipes of the type mentioned, in which the individual pipes can be pivoted from a roughly linear arrangement in a compact arrangement in the pipe assembly, in view of an advantageous rational production improve.
Die Lösung dieser Aufgabe liefert ein Verfahren zur Herstellung eines Rohrverbunds aus wenigstens zwei Kunststoffrohren der eingangs genannten Gattung mit den kennzeichnenden Merkmalen des Hauptanspruchs.The solution to this problem provides a method for producing a composite pipe from at least two plastic pipes of the aforementioned type with the characterizing features of the main claim.
Erfindungsgemäß ist vorgesehen, dass als Verbundmittel ein Folienmaterial dient, welches auf Teilabschnitte des Umfangs der äußeren Mantelfläche wenigstens zweier separat extrudierter Einzelrohre in einer Konfiguration, in der diese Einzelrohre parallel nebeneinander liegen, aufgeschweißt wird. It is provided according to the invention that a film material serves as the composite, which is welded onto portions of the circumference of the outer surface of at least two separately extruded individual tubes in a configuration in which these individual tubes are parallel to each other.
Ein Vorteil dieses Verfahrens liegt darin, dass man in einer Fertigungslinie nicht unbedingt auf bestimmte Rohrdurchmesser festgelegt ist. Es können zwei, drei, vier oder mehr Einzelrohre mit gleichen oder unterschiedlichen Durchmessern gegebenenfalls in separaten Extrusionslinien gefertigt werden, die dann einer Fertigungslinie zugeführt werden, in der der Rohrverbund mittels des Folienmaterials hergestellt wird. Da das Folienmaterial tangential auf die in etwa linearer Anordnung nebeneinander liegenden Einzelrohre aufgebracht und mit diesen verschweißt wird, können Einzelrohre in unterschiedlicher Anzahl und unterschiedlicher Durchmesser verbunden werden. Die vorgenannte Einschränkung in der Fertigungslinie wie beim Aufschrumpfen einer Deckschicht auf ein Bündel von um eine gemeinsame Achse gruppierten Einzelrohren besteht somit nicht. Es ergeben sich vielmehr erhebliche Freiheitsgrade in der Fertigungslinie, die eine flexiblere Fertigung ermöglichen.An advantage of this method is that it is not necessarily fixed to a certain pipe diameter in a production line. Two, three, four or more individual tubes with the same or different diameters may optionally be manufactured in separate extrusion lines, which are then fed to a production line in which the tube assembly is produced by means of the foil material. Since the film material is applied tangentially to the approximately linear arrangement adjacent individual tubes and welded to them, individual tubes can be connected in different numbers and different diameters. The abovementioned restriction in the production line, such as when shrinking a covering layer onto a bundle of individual tubes grouped around a common axis, does not exist. On the contrary, considerable degrees of freedom result in the production line, which enable a more flexible production.
Ein weiterer Vorteil liegt darin, dass man in einem solchen Rohrverbund Rohre mit verschiedenen Rohrdurchmessern und/oder Querschnittsformen und/oder Farben oder Farbkennzeichnungen bei der Fertigung in einem Produkt zusammenführen kann. Wenn beispielsweise der Rohrverbund nach der Fertigung auf eine Trommel gewickelt wird, so erfolgt diese Wicklung im Flachverbund, so dass nur geringe Wickelspannungen entstehen und keine Torsion der Rohre auftritt. Wenn hingegen der Rohrverbund um eine in Längsrichtung verlaufende Achse gefaltet wird, entsteht ein Rohrverbund mit verringertem Gesamtquerschnitt, der sich mit geringem Widerstand beispielsweise in einen Kabelschacht einziehen lässt oder in ein Kabelrohr. Auch die Verlegung des Rohrverbunds in grabenloser Technik wird vereinfacht. Da keine Torsionen mehr auftreten, sind größere Verlegelängen möglich.Another advantage is that in such a composite pipe can combine pipes with different pipe diameters and / or cross-sectional shapes and / or colors or color codes in the production in a product. If, for example, the tube assembly is wound on a drum after production, this winding takes place in the flat composite, so that only low winding stresses occur and no torsion of the tubes occurs. If, however, the pipe assembly is folded around a longitudinal axis, creates a composite pipe with reduced overall cross-section, which can be retracted with little resistance, for example, in a cable duct or in a cable conduit. The laying of the pipe assembly in trenchless technology is also simplified. Since no more torsions occur, larger laying lengths are possible.
In einem Rohrverbund der erfindungsgemäßen Art können auch beispielsweise ein oder mehrere kleinere Rohre innerhalb des Querschnitts eines größeren Rohrs liegen, das heißt die Rohre liegen im Rohrverbund dann nicht nebeneinander sondern (teilweise) ineinander.In a composite pipe of the type according to the invention, for example, one or more smaller pipes can be within the cross section of a larger pipe, that is, the pipes are not adjacent to each other in the pipe assembly but (partially) into each other.
Eine mögliche bevorzugte Lösungsvariante im Rahmen der vorliegenden Erfindung sieht vor, dass das Folienmaterial tangential am äußeren Umfang wenigstens zweier benachbarter Einzelrohre anliegt, wobei diese Einzelrohre einen Abstand zueinander aufweisen, das Folienmaterial den durch den Abstand gegebenen Zwischenraum zwischen den Einzelrohren flächig überspannt und das Folienmaterial aufgrund seiner Flexibilität Schwenkbewegungen der Einzelrohre zueinander im Rohrverbund um eine zu deren Achsen etwa parallele Achse zulässt.A possible preferred solution variant in the context of the present invention provides that the film material bears tangentially on the outer circumference of at least two adjacent individual tubes, these individual tubes have a distance from each other, the film material spans the distance between the individual tubes given by the distance surface and the film material due its flexibility allows pivoting movements of the individual tubes in the pipe assembly about an axis approximately parallel to the axis.
Das für die Verbindung der Rohre verwendete Folienmaterial kann in seiner Materialstärke innerhalb weiter Bereiche variieren. Es können ferner auch Verbundfolien aus diversen Materialkombinationen verwendet werden, die beispielsweise auch Schichten mit definierten Funktionen aufweisen können. Dazu können beispielsweise ortungsfähige Elemente in das zur Verbindung der Rohre im Rohrverbund verwendete Folienmaterial eingebracht werden. Der Rohrverbund kann neben den Rohren Zusatzelemente wie zum Beispiel Glasfaserkabel, Reißfäden, Ortungsdrähte oder Zugelemente für das Einziehen in das Erdreich umfassen. Derartige Ortungsdrähte können beispielsweise wie zuvor erwähnt in das Folienmaterial eingearbeitet sein.The film material used for the connection of the tubes may vary in material thickness within wide ranges. It can also be used composite films of various combinations of materials, which may for example also have layers with defined functions. For this purpose, for example, locatable elements can be introduced into the foil material used to connect the tubes in the tube assembly. The composite tube may include, in addition to the tubes, additional elements such as fiber optic cables, ripcords, locating wires or pulling elements for insertion into the ground. Such locating wires may for example be incorporated in the film material as mentioned above.
Man kann beispielsweise so vorgehen, dass zunächst ein Kunststoffschmelzefilm bereichsweise im Verbindungsbereich auf die zu verbindenden Einzelrohre aufgebracht, vorzugsweise aufextrudiert wird und anschließend das Folienmaterial auf die mit dem Schmelzefilm versehenen Verbindungsbereiche der zu verbindenden Einzelrohre aufgebracht und danach mit den Einzelrohren verschweißt wird. Dabei kann beispielsweise mittels einer dazu geeigneten Vorrichtung das Folienmaterial mittels eines definierten Schweißdrucks auf die Verbindungsbereiche der Mantelflächen der Einzelrohre aufgebracht werden.For example, it is possible to initially apply, preferably extrude, a plastic melt film to the individual tubes to be joined in the connection region, and then apply the foil material to the connecting regions of the individual tubes to be connected with the melt film and then weld them to the individual tubes. In this case, for example by means of a device suitable for this purpose, the film material can be applied by means of a defined welding pressure to the connecting regions of the lateral surfaces of the individual tubes.
Der vorgenannte Schmelzefilm, der bevorzugt vor dem Aufschweißen des Folienmaterials aufgebracht wird, kann beispielsweise aus einem Polyolefin, insbesondere PE, PP, LDPE, LLDPE, HDPE, MDPE, aber auch aus anderen Kunststoffen bestehen.The abovementioned melt film, which is preferably applied prior to the welding of the film material, can consist for example of a polyolefin, in particular PE, PP, LDPE, LLDPE, HDPE, MDPE, but also of other plastics.
Weiterhin kann es vorteilhaft sein, wenn die zu dem Rohrverbund zu verbindenden Einzelrohre vor der Aufbringung des Folienmaterials vorgewärmt werden.Furthermore, it may be advantageous if the individual pipes to be connected to the pipe assembly are preheated before the application of the film material.
Besonders vorteilhaft an der erfindungsgemäßen Lösung ist, dass man die Rohre im Rohrverbund vor Ort vor der Verlegung durch Klappen oder Schwenken um eine zur Achse der Einzelrohre parallele Achse in eine kompakte Konfiguration mit um eine gemeinsame mittlere Achse gruppierten Rohren bringen kann. Eine solche Anordnung lässt sich platzsparenden beispielsweise in ein Kanalrohr oder ein größeres Schutzrohr einbringen. Man ist aber gleichwohl nicht auf diese Anordnung festgelegt, sondern kann auch den Rohrverbund so verlegen, dass die Einzelrohre nach der Verlegung parallel nebeneinander liegen und eine etwa lineare Anordnung bilden, das heißt die Rohre liegen nach der Verlegung im Verbund so wie nach dessen Herstellung. Die Gefahr unerwünschter Torsionen der Einzelrohre tritt bei einem solchen Rohrverbund auch dann nicht auf, wenn dieser nach der Herstellung auf eine Trommel aufgewickelt wird und so an den Verlegeort verbracht wird.A particular advantage of the inventive solution is that you can bring the pipes in the pipe assembly on site before laying by folding or pivoting about an axis parallel to the axis of the individual tubes in a compact configuration with a common central axis grouped tubes. Such an arrangement can be space-saving, for example, in a sewer pipe or a larger protective tube bring. However, it is nevertheless not fixed to this arrangement, but can also lay the pipe assembly so that the individual pipes lie parallel next to each other after installation and form an approximately linear arrangement, that is, the pipes lie after laying in the composite as well as after its production. The risk of unwanted torsions of the individual tubes does not occur in such a composite pipe even if this is wound up after production on a drum and is thus brought to the installation site.
Rohrverbunde aus Kunststoffrohren der eingangs genannten Art werden insbesondere im Außenbereich in offener oder gegebenenfalls auch in geschlossener Bauweise (grabenlos) verlegt. Die einzelnen Rohre des Rohrverbunds dienen beispielsweise als Leerrohre oder Schutzrohre für Telekommunikations-, Daten, Signal- oder Energieleitungen. Insbesondere wegen der zunehmenden Bedeutung von Glasfasernetzen für die Datenübertragung wird in naher Zukunft die Verlegung von Rohrverbunden der genannten Art in erheblichem Umfang notwendig. Glasfaserkabel können in die Leerrohre des Rohrverbunds eingeblasen oder eingezogen werden. Die Verlegung eines solchen Rohrverbunds erfolgt meist in großen Längen von beispielsweise 100 m oder mehreren 100 m. Der Rohrverbund wird dabei beim Hersteller auf große Trommeln gewickelt, zur Baustelle transportiert und bei der Verlegung vor Ort nach und nach von der Trommel abgewickelt.Pipe assemblies made of plastic pipes of the type mentioned above are laid in particular in the outdoor area in open or possibly also in closed construction (trenchless). The individual tubes of the composite pipe, for example, serve as conduits or protective tubes for telecommunications, data, signal or power lines. In particular, because of the increasing importance of fiber optic networks for data transmission in the near future, the laying of pipe joints of the type mentioned in a considerable extent necessary. Fiber optic cables can be blown or drawn into the conduits of the pipe network. The laying of such a composite pipe is usually done in long lengths, for example, 100 m or several 100 m. The pipe assembly is wound at the manufacturer on large drums, transported to the site and unwound from the drum during installation on site gradually.
Gegenstand der vorliegenden Erfindung ist weiterhin eine Anlage zur Herstellung eines Rohrverbunds in einem Verfahren der zuvor genannten Art, umfassend wenigstens eine Abwickelstation an der wenigstens zwei Einzelrohre abgewickelt und einer Bearbeitungslinie zugeführt werden, in der die Einzelrohre etwa parallel zueinander in einer Vorschubrichtung gefördert werden, wenigstens eine sich im Vorschubweg daran anschließende Führungs- und Vorwärmestation für die Einzelrohre, wenigstens eine Folienabwickelstation sowie wenigstens eine Station, in der das Folienmaterial aufgebracht und mit den Einzelrohren zu einem Rohrverbund verschweißt wird.The subject of the present invention is furthermore a plant for producing a composite pipe in a process of the aforementioned kind, comprising at least one unwinding station on which at least two individual pipes are unwound and fed to a processing line in which the individual pipes are conveyed approximately parallel to one another in a feed direction, at least an adjoining in the feed path guide and preheating station for the individual tubes, at least one Folienabwickelstation and at least one station in which the film material is applied and welded to the individual tubes to form a composite pipe.
Eine solche erfindungsgemäße Anlage kann beispielsweise weiterhin wenigstens eine Wärmestation und/oder der Aufbringung des Folienmaterials nachgeschaltete Kühleinrichtungen für den Rohrverbund und/oder wenigstens eine Abzugsvorrichtung und/oder wenigstens eine Vorrichtung zur Aufwicklung des Rohrverbunds umfassen.Such a system according to the invention may further comprise, for example, at least one heat station and / or cooling means connected downstream of the foil material for the tube assembly and / or at least one withdrawal device and / or at least one device for winding the tube assembly.
