Claims (7)

1. Anordning (12) til reparation af en rørledning (10), hvilken anordning omfatter: et aflangt foringsrør (28) med en foringsrørvæg (30) af et resinabsorberende materiale, hvilken foringsrørvæg (30) har første og anden modstående vægoverflader og foringsrøret (28) har mindst en første (34) og anden (36) ende, en ikke-hærdet og ikke-størknet resin imprægneret i foringsrørvæggens (30) resinabsorberende materiale; et forlængelsesrør (48) med en rørformet åben ende (56) og en modstående lukket ende (50), hvor den rørformede åbne ende (56) er løst fastgjort til den anden ende (36) af foringsrøret (28) ved hjælp af et tætningselement og danner en i alt væsentligt fluidtæt tætning der imellem; et inversionsmiddel forbundet med den første ende (34) af foringsrøret (28) for invertering af foringsrøret (28) og forlængelsesrøret (48) ffa en startposition, hvor den første vægoverflade af foringsrørvæggen vender i en indadgående radial retning og den anden vægoverflade af foringsrøret vender i en udadgående radial retning til en inverteret position, hvor den første vægoverflade vender i en udadgående radial retning og den anden vægoverflade i en indadgående radial retning; kendetegnet ved, at forlængelsesrøret (48) ikke strækker sig i en fuld længde af foringsrøret (28).
2. Anordning (12) ifølge krav 1, hvor tætningselementet omfatter et klæbemateriale (58) viklet omkring den rørformede åbne ende (56) af forlængelsesrøret (48) og den anden ende (36) af foringsrøret (28).
3. Anordning (12) ifølge krav 2, hvor tætningselementet endvidere omfatter én eller flere tapper (60), der hver har én ende fastgjort til forlængelsesrøret (48) og en modsat ende løst forbundet med foringsrøret (28).
4. Fremgangsmåde til reparation af en rørledning (10) kendetegnet ved: at tage et foringsrør (28) med en første (34) og anden (36) modstående foringsrørende og en foringsrørvæg (30) omfattende et absorberende materiale, der kan absorbere en uhærdet resin, hvilken foringsrørvæg (30) har en første og anden modstående vægoverflade; fastgørelse af en rørformet ende (56) af et forlængelsesrør (48) til den anden foringsrørende (36), hvilket forlængelsesrør (48) har en lukket ende (50) modsat den rørformede ende (56) og forlængelsesrøret (48) ikke strækker sig i en fuld længde af foringsrøret (28); imprægnering af foringsrørvæggens (30) absorberende materiale med en uhærdet resin; fastgørelse af et inverteringsmiddel til den første foringsrørende (34); anvendelse af inverteringsmidlet til at invertere foringsrøret (28) og forlængelsesrøret (48) i rørledningen (10) fra en startposition, hvor den første vægoverflade af foringsrøret (28) vender i en indadgående radial retning og den anden vægoverflade af foringsrøret (28) vender i en udadgående radial retning, til en inverteret position, hvor den første vægoverflade af foringsrøret vender i en udadgående radial retning og den anden vægoverflade i en indadgående radial retning; at tillade at resinen hærder og størkner; trækning af forlængelsesrøret (48) væk fra foringsrøret (28) for at frigøre forlængelsesrøret (48) fra foringsrøret (28).
5. Fremgangsmåde ifølge krav 4, hvor den lukkede ende af forlængelsesrøret (50) lukkes, efter at foringsrøret (28) er imprægneret med en uhærdet resin.
6. Fremgangsmåde ifølge krav 4, hvor fastgørelsestrinnet omfatter anvendelse af et tætningselement til fastgørelse af foringsrøret (28) til forlængelsesrøret (48).
7. Fremgangsmåde ifølge krav 6, hvor trinnet med trækning af forlængelsesrøret (48) væk fra foringsrøret (28) endvidere omfatter frigørelse af tætningselementet fra foringsrøret (28), mens tætningselementet holdes fastgjort til forlængelsesrøret (48).
