   Der in der Pfeilrichtung   A   sich bewegende Sand setzt sich an den Zacken c fest und dringt in die bei der Herstellung der Zacken gebildeten Löcher der Rohrwandung b ein, bis das ganze Rohr innen mit einer äusserst harten Sandkruste ausgefüttert ist, wie z. B. Fig. 2 punktiert bei e erkennen lässt. Diese Sandkruste bildet nunmehr das denkbar beste Futter und wird dadurch   nunmehr weder   das Blechfutter b noch das Leitungsrohr a irgendwie beschädigt.

   The sand moving in the direction of the arrow A attaches itself to the prongs c and penetrates the holes in the pipe wall b formed during the production of the prongs until the whole pipe is lined with an extremely hard sand crust on the inside, such as B. Fig. 2 can be seen dotted at e. This sand crust now forms the best possible lining and is no longer damaged in any way, neither the sheet metal lining b nor the pipe a.

PATENT-ANSPRUCH : Neuartige Ausfutterung für Sandleitungsrohre beim Spülversatz, dadurch gekennzeichnet, dass in das zu schützende Leitungsrohr ein dünnwandiges Blech oder Rohr gebracht wird, welches mit Rippen, ausgestanzten Zacken oder sonstigen nach innen gerichteten Vorsprüngen versehen ist, die zweckmässig der Sandbewegung entgegengesetzt gerichtet sind, so dass sich hieran und in den in der Blechwandul1g befindlichen Löchern der Leitungssand festsetzt, bis er über dem Hlechfutter eine harte Kruste bildet, auf welchem Sandfutter sich dann der Versatzwand bewegt. EMI2.1 PATENT CLAIM: A new type of lining for sand pipelines during flushing displacement, characterized in that a thin-walled sheet metal or pipe is brought into the pipeline to be protected, which is provided with ribs, punched-out prongs or other inwardly directed projections, which are expediently directed opposite to the sand movement, so that on this and in the holes in the sheet metal wall the pipe sand sticks until it forms a hard crust over the metal lining, on which sand lining the offset wall then moves.
