En underjordisk hovedrørledning eller kanal (60) er foret med et foringsrør som strekker seg over et siderørs (61) forbindelse med hovedrørledningen eller kanalen (60). Ifølge oppfinnelsen kan denne siderørsforbindelse lett loka- liseres og fdringsrøret (81) bli skåret ut for å gjenopp- rette forbindelsen, dersom et middel, såsom en stålkule (78) eller en avsetning, som er påviselig ved stråling, anbringes på rørledningens eller kanalens (60) flate i en forutbestemt avstand fra nevnte siderørsforbindelse.An underground main pipe or duct (60) is lined with a casing extending over a side pipe (61) to the main duct or duct (60). According to the invention, this side tube connection can be easily located and the casing (81) cut out to restore the connection if a means, such as a steel ball (78) or a deposition, which is detectable by radiation, is applied to the pipeline or duct ( 60) surface at a predetermined distance from said side pipe connection.
