The invention relates to a method for laying carrier cables, more particularly telephone lines, comprising the steps of burying a bundle of pipes connected to a connection box supplied by a main cable, severing certain of the pipes forming part of the bundle to constitute a local opening therein at the suitable spot, connecting one end of a secondary connection pipe to the severed opening of the pipe forming part of the bundle, the opposite end of said secondary connection pipe terminating at the apparatus to be supplied, passing a secondary branch cable in the severed pipe extended by the secondary connection pipe, one side of which cable thus terminates at the connection box and the other at the apparatus to be connected to the system. The invention also concerns a bundle of pipes for carrying out the method.
