Abstract
Oppfinnelsen vedrører et dreneringsrør (1) av plast, som kan benyttes som flerformåls- eller del- dreneringsrør, hvor et glattvegget innerrør (2) omgis av et bølgerør (3) og er sveiset sammen med dettes bølgedaler (4) samt er forsynt med slisslignende gjennombrytninger (8) for passasje av dreneringsfluid. Bølgerøret (3) omgis videre av et ytre rør (6) som ifølge oppfinnelsen bare i et område av gjennombryt- ningene (8) ved rørtoppen er inntrykket og perforert i bølgedalene (4), mens det øvrige rørområde er glatt. Tilføyelsen av et ytre rør (6) tjener til ved enkel og billig fremstilling å oppnå bedre stivhet og å øke rørtoppens trykkfasthet.
