摘要
The invention relates to a method for installing at least one pipe line and/or an empty conduit in supply and sanitation pipes which have already been laid, especially in sewer pipe systems or networks and similar. According to said method, the pipe lines and/or empty conduits being laid are introduced into the pipe and fixed to its wall. The invention is characterised in that a tube- or hose-shaped inner lining is inserted/drawn into the pipe which is already laid and at least one flexible empty conduit and/or a pipeline are arranged in the area of its outer surface.
