Abstract

Ved en fremgangsmåte til f6ring av underjordiske rørledninger og passasjer, fylles en f6ringsslange som er impregnert med herdbar syntetisk harpiks med varmt vann for å presse slangen inn mot overflaten av rørledningen eller passasjen, og også for å varmeherde harpiksen. Når herdingen er fullført blir foringen frittstående på over- flaten av rørledningen eller passasjen. Ved den fore- liggende oppfinnelse gjennomføres den samme fflringsopera- sjon, men oppvarmingen gjennomføres trinnvis ved å isolere lengder av f6ringsslangen i rekkefølge og ved å sirkulere varmt vann i rekkefølge gjennom de isolerte lengder. Det oppnås betydelige fordeler ved at det er behov for å opp- varme mye mindre vannmengder.In a method of lining underground pipelines and passageways, a lining hose impregnated with curable hot water synthetic resin is filled to press the hose into the surface of the pipeline or passage and also to heat cure the resin. When curing is complete, the lining becomes free-standing on the surface of the pipeline or passage. In the present invention, the same lining operation is carried out, but the heating is carried out in stages by isolating lengths of the lining hose in sequence and by circulating hot water in sequence through the insulated lengths. Significant benefits are obtained by the need to heat much smaller quantities of water.
