Description

Schutzrohr mit vorzugsweise äusserer Belagschicht.Protective tube with preferably an outer layer of coating.

Aus Gründen der Sicherheit werden Eohrleittuigen durch Böschungen sowie unter Strassen-* und Bahn-Anlagen in den meisten Pällen unter Zuhilfenahme von Schutzrohren geführt. Diese sollen der erdverlegten Bohrleitung einen festen Halt gehen und Beschädigungen an ihr und an den Bauwerken verhindern.For security reasons, Eohrleittuigen are carried out Embankments as well as under road * and railway systems in most Palls with the help of protective tubes guided. These should give the buried drilling line a firm hold and damage it and the Prevent structures.

Durch die gro.sse Beanspruchung derartiger Eohre "beim, linbau, der in vielen iällen durch «Pressen1' erfolgt, wird eine vorhandene Isolierung aus Bitumen oder aus Überzügen, die durch Anstrich, Spritzen oder Hauchen hergestellt wurden, so "beschädigt, dass ihre isolierende Wirkung weitgehenxLeingesehränkt bzw. sogar ganz aufgehoben ist.As a result of the great stress on such tubes "during" linbau ", which is done in many cases by" pressing 1 ", an existing insulation made of bitumen or coatings that have been produced by painting, spraying or breathing is damaged in such a way that its isolating effect is largely limited or even completely abolished.

Inhalt der !Teuerung ist deshalb ein Schutzrohr mit einem isolierenden Belag hoher mechanischer Widerstandsfähigkeit und geringem Abrieb. Es besteht nach der !Teuerung in folgendem Aufbau ι The content of the inflation rate is therefore a protective tube with an insulating coating of high mechanical resistance and low abrasion. After inflation, it consists of the following structure ι

1.) Das Rohr (1) (vorzugsweise Stahlrohr) ist, gegebenenfalls über einem Voranstrich, mit einem einfachen oder mehrfachen, durch Streichen oder Spachteln von Kunsthar-z-. gemischen mit Quarzsand, Korund oder einem ähnlichen abriebfesten körnigen oder pulverformigen ICaterial hergestellten Belag versehen. Auf diese Weise besteht, wie in Mg, 1 der beigefügten Zeichnung dargestellt, nach der Aushärtung auf der Rohroberfläche (1) ein gut haftender, mechanisch fester Belag (2), der gleichzeitig korrosionschützende Wirkungen ausübt«1.) The pipe (1) (preferably steel pipe) is, if necessary over a primer, with a single or multiple, by painting or filling with synthetic resin. mixed with quartz sand, corundum or a similar abrasion-resistant granular or powdery material Covering provided. In this way, as in Mg, 1 shown in the accompanying drawing after curing On the pipe surface (1) a well-adhering, mechanically strong coating (2), which at the same time has anti-corrosive effects exercises «

2) In einer weiteren Ausführung der Feuerung gemäss fig, der Zeichnung ist die schützende Belagsehieht des Rohres (1) so aufgebaut, dass zunächst der Belag des Kunstharzgemisches (2) aufgetragen erscheint, line weitere Schicht (5) über diesem Belag (2) besteht aus dem genannten körnigen oder pulverförmigen Material, wobei dieser Belag (3) durch linstreuen in die noch feuchte erste Schicht entstanden ist. Hierauf ist ein weiterer, vor völliger Aushärtung der ersten beiden Schichten (2 + 3) aufgebrachter Belag (4) eines Kunstharzgemisches angeordnet.2) In a further embodiment of the furnace according to fig, the drawing is the protective layer of the pipe (1) constructed in such a way that the synthetic resin mixture is initially covered (2) appears applied, line another layer (5) over this covering (2) consists of the granular or mentioned powdery material, this covering (3) through sprinkle linseed into the still damp first layer. On top of this is another one before the first one completely hardens two layers (2 + 3) applied coating (4) of a synthetic resin mixture arranged.

lach völliger Aushärtung der genannten drei Schichten ergibt sich der Gegenstand gemäss: der leuerung mit den geschilderten Torteilen.After complete hardening of the three layers mentioned, the object is obtained according to : the fire with the gate parts described.

Die verwendeten Kunstharze gehören vorzugsweise der Gruppe der Epoxydharze, (Aethoxylinharze) oder der PoIyestergruppe an. Selbstverständlich kann nach der Heuerung auch eine Belagschicht auf der inneren Oberfläche des Sehutzrohres aufgebracht sein.The synthetic resins used preferably belong to the group the epoxy resins, (ethoxylin resins) or the polyester group at. Of course, a layer of pavement can also be added after the hiring be applied to the inner surface of the protective tube.
