| 摘要 |
The invention relates to a method to carry out a branching point (1) of a pipe line under repair. The method comprises applying a pipe lining mass (4) to the branch point (1) in such a way that it extends in a main pipe (2) in either direction from the branch point and into a branch pipe (3), establishing a substantially integral branch connection. At least one of the pipe lengths arriving at the branch point is renovated with a per se known sock lining method by edging a sock (5, 7) to its position prior to setting of the pipe lining mass (4), such that the renovation sock extends at least partially over the part of branch connection present in the discussed pipe length (2, 3). The material for a mass used in the sock (5, 7) is selected on the basis of its compatibility with the pipe lining mass (4), such that the renovation sock and the branch connection establish with each other a substantially integral jointless conjunction upon setting of the masses contained therein.
