Verfahren zur Herstellung von Rohren aus Kunststeinmassen, insbesondere Beton.
Es ist bekannt, die Innenwand von Rohren durch Überziehen mit Asphalt od. dgl. abzudichten, zu isolieren oder verschleissfest zu machen. Derartige Auskleidungen reissen, bröckeln ab oder nutzen sich rasch ab. Die Wärmedichtheit wird damit kaum erhöht.
Gemäss der Erfindung werden dagegen die erwünschten Eigenschaften dadurch erzielt, dass auf die Innenwand des fertiggeformten Kunststeinrohres in Bitumen vorzugsweise Asphalt getränktes Textilgewebe in ein oder mehreren Lagen unter zusätzlichem Bitumenaufstrich aufgebracht wird.
So werden nach irgendeinem bekannten Verfahren, beispielsweise durch Schleudern, bereits fertiggeformte Betonrohre grösserer lichter Weite mit Bitumen innen ausgestrichen, worauf beispielsweise eine runde, vorzugsweise eiserne Spindel, auf welcher ein weitmaschiges mit Bitumen durchgetränktes Gewebe aufgewickelt ist, in das Rohrinnere eingeführt wird. Durch Drehen des Rohres und der Spindel wird das Gewebe von der Spindel abgewickelt und durch das Gewicht des beim Drehen der Spindel sich auf dieser abrollenden Rohres auf die bestrichen Rohrwand gleichmässig aufgepresst.
Ein nochmaliger Bitumenanstrich bettet das Gewebe in den Asphalt vollständig ein.

Process for the production of pipes from artificial stone masses, in particular concrete.
It is known that the inner wall of pipes can be sealed, insulated or made wear-resistant by covering them with asphalt or the like. Such linings tear, crumble or wear out quickly. The heat tightness is hardly increased.
According to the invention, on the other hand, the desired properties are achieved in that textile fabric, preferably asphalt-soaked in bitumen, is applied in one or more layers with an additional bitumen coating on the inner wall of the finished artificial stone pipe.
So, according to any known method, for example by spinning, already formed concrete pipes of larger clear width are coated with bitumen on the inside, after which, for example, a round, preferably iron spindle, on which a wide-meshed fabric soaked with bitumen is wound, is inserted into the pipe interior. By turning the tube and the spindle, the tissue is unwound from the spindle and is evenly pressed onto the coated tube wall by the weight of the tube rolling on this when turning the spindle.
Another bitumen coating completely embeds the fabric in the asphalt.
