ABSTRACT OF THE DISCLOSURE A specific feature of the claimed pipeline is that it is made of coaxially arranged envelopes rigidly connected to each other, wherein an internal envelope is made of non hermetic as well as hermetically sealed layers and an external envelope is made of ground soil, the whole set of envelopes being impregnated with a binder, thus forming a monolithic structure. The method is characterized by the formation of holes in the ground, the insertion therein of the non hermetic and hermetically sealed layers of the internal envelope, the impregnation of the ground soil with the binder, followed by the expansion and the densing of the envelopes, by producing an excess pressure of the working medium in the pipeline. The device includes a propelling unit having a frame on which a working member for forming a hole in the ground is mounted as well as a mechanism for inserting the layers of the internal envelope of the pipeline. The mechanism comprises two units, one of which is stationarily mounted above the hole and used for inserting the hermetically sealed layers of the internal envelope, whereas the other unit is mounted on the propelling unit and is used for inserting the non hermetic layers into the hole. The device is also provided with a means for fixing the ends of the envelope, the means being installed at the point of origination of these layers.
