Subsequently, a resin impregnated lining element 70 that a main section 72 and a side section 74 has, on the calibration hose 10 postponed. When deferred, the main section surrounds 72 the main pipe calibration hose 18 and the side section 74 is so in the range of Seitenrohrkalibrierschlauches 20 arranged that the Seitenrohrkalibrierschlauch 20 in the inflated state by the side portion 74 can extend as in 1 is shown. Then the calibration tube 10 inflated to check for its tightness. Then the air is removed from the calibration tube 10 drained and the side tube calibration tube 20 over at the second end area 28 into the interior of the side tube calibration tube 20 projecting Zugmittelanschlusseinrichtung 29 by an unillustrated rope into the interior of the Hauptrohrkalibrierschlauches 18 invaginated. Following this, the packer is so to the refurbishment area to be rehabilitated 12 procede that the rare tube calibration tube 20 in the house connection pipe 16 is einülpbar. After the exact positioning of the calibration tube 10 pressurized and at the same time the Seitenrohrkalibrierschlauch 20 with the help of an outwardly projecting Zugmittelanschlusseinrichtung 29 attached rope or pipe hall not shown in the house connection pipe 16 invaginated. As a result of the loading of the calibration tube 10 with pressure the lining element becomes 70 at the junction 12 , the main pipe 14 and the house connection pipe 16 pressed and cured. After curing of the lining element 70 the air is drained from the calibration tube. Furthermore, the Seitenrohrkalibrierschlauch 20 with the help of the rope into the main pipe calibration hose 18 invaginated. Then the packer is out of the main pipe 14 away.

The calibration tube according to the invention 10 is characterized by the fact that the Seitenrohrkalibrierschlauch 20 detachable with the main pipe calibration hose 18 connected is. This makes it possible one of the two hoses 18 . 20 easy to replace. Further, depending on the length of the side pipe section a Seitenrohrkalibrierschlauch 20 with appropriate length to the main pipe calibration hose 18 be attached. For example, if the Seitenrohrkalibrierschlauches damage 20 this can be easily replaced without the entire calibration tube 10 must be replaced. Furthermore, when using two separate hoses 18 . 20 the handling of the calibration tube 10 increased when pushed onto the packer or when removing from the packer. In addition, depending on the nature of the pipes or depending on the angle at which the service pipe 16 from the main pipe 14 protrudes, a corresponding calibration hose 10 be assembled.
