Abstract
The method concerned is for connecting a section of buried main conduit (120) to a secondary conduit. For this purpose, a starting pit (200) and a finishing pit (204) are dug, a drilling device comprising a series of rods to be placed end to end is lowered into one pit in a manner such as to drill along a horizontal axis at the level of or at a height close to that of the main conduit. Upon completion of the drilling, the secondary conduit is passed through the bore-hole (202) in a manner such that an end portion is situated above the pit, this portion is fixed to a first region of a branch connector for connecting the two conduits and this end portion, equipped with its connecter, is lowered into the pit and the connector is fixed to the main conduit.
