Description
GEBRAUCHSMUSTER-ANHELDUNG
Abwässer mit korrodierenden Substanzen werden im allgemeinen durch säurefeste Beton-oder Tonrohre geleitet. Die Beständigkeit dieser Werkstoffe ist jedoch für mannigfache Verwendungszwecke unzureichend.Wastewater with corrosive substances is generally carried through acid-proof concrete or clay pipes. The resistance of these materials is however, inadequate for a variety of purposes.
Bei Tonrohre wirkt sich die relativ hohe Bruchempfindlichkeit nachteilig aus. Sie erfordern zudem bei der Herstellung und in'der Wartung grosse Aufwendungen. Das Überziehen von Ton-und Betonrohren mit säurefesten Spachtelmassen und Bitumen, sowie Kunststoffauskleidungen dieser Rohre sind bekannt. Derartige Überzüge neigen aber zum Reißen, ausserdem erfolgt beim Auftragen der Überzüge Porenbildung, wodurch eine rauhe Oberfläche entsteht. Ein entscheidender Mangel ist die Verbindung zweier solcher Rohre miteinander. Diese erfolgt durch die übliche Dichtung wie Asbest oder Gummi. Bei Kunststoffrohren bestand bisher der Nachteil hoher Druckempfindlichkeit.In the case of clay pipes, the relatively high sensitivity to breakage is disadvantageous the end. They also require great expenditures in terms of manufacture and maintenance. The coating of clay and concrete pipes with acid-resistant fillers and bitumen, and plastic linings for these pipes are known. Such coatings tend to be but tearing, and pore formation occurs when the coatings are applied, as a result of which a rough surface is created. A crucial flaw is the connection between the two such pipes with each other. This is done by the usual seal such as asbestos or Rubber. In the past, plastic pipes had the disadvantage of high pressure sensitivity.
Es wurde nun gefunden, und dies bildet den Gegenstand der Erfindung, dass Rohre aus thermoplastischen Kunststoffen wie Polyolefinen, Polyäthylen, Polyvinylchloriden u. ä., deren Verbindungen durch Heissluft-oder Stumpfschweissung erfolgte, für Abwässer mit korrodierenden Substanzen besonders vorteilhaft sind, wobei die Druckempfindlichkeit durch eine Verankerung der Rohre in Beton ausgeschaltet wird. Besonders für die Verankerung durch Verzahnung geeignete Kunststoffrohre haben an ihrer Aussenfläche bei der Extrusion erzeugte Aufrauhungen oder Profile von schwalbenschwanzartigen Nocken und Rillen. Solche in Beton gebettete Rohre sind wesentlich druckunempfindlicher, als übliche Kunststoffrohre.It has now been found, and this forms the subject of the invention, that pipes made of thermoplastics such as polyolefins, polyethylene, polyvinyl chlorides and the like, the connections of which are made by hot air or butt welding, for waste water with corrosive substances are particularly advantageous, the pressure sensitivity is eliminated by anchoring the pipes in concrete. Especially for that Anchoring by toothing, suitable plastic pipes have on their outer surface Roughening or dovetail-like profiles produced during extrusion Cams and grooves. Such pipes embedded in concrete are much less sensitive to pressure, than usual plastic pipes.
Die beigefügte Zeichnung gibt den Querschnitt eines eingebetteten Kunststoffrohres nach der Erfindung wieder, wobei A der Betonblock ist, in den das Polyolefinrohr B eingelassen ist und C eine der schwalbenschwanzartigen Nocken darstellt.The attached drawing gives the cross section of an embedded Plastic pipe according to the invention again, where A is the concrete block in which the Polyolefin tube B is embedded and C represents one of the dovetail-like cams.
