Abstract: A method is disclosed for the trenchless laying of a pipeline, the medium pipe, from a starting location to a target location. First of all a protective pipe is introduced into the ground between the starting location and the target location in a trenchless method. A medium pipe whose outside diameter is smaller than the inside diameter of the protective pipe is introduced into the protective pipe starting from the starting location and moved forward as far as the target location. The medium pipe is stabilized in its spatial position with respect to the protective pipe in the radial direction. The protective pipe is finally removed from the ground again while maintaining the spatial position of the medium pipe.

Abstract: Thrust pipe for disposition in a passage in the ground by advance of the pipe axially through the passage includes a plurality of pipe segments disposed in end-to-end relation one to the other. Each pipe segment includes an inner pipe section having a diametrically enlarged end for telescopically receiving the opposite end of an adjacent inner pipe section. The pipe segments each include an outer pipe section, substantially enveloping a corresponding inner pipe section. The outer surface of the pipe segments is smooth and substantially continuous. Each outer pipe section at one end terminates short of the end of the corresponding inner pipe seciton and is spaced from the outer pipe section of the adjacent pipe segment whereby compressive loadings from thrusting the pipe axially through the passage are carried by the inner pipe sections and not be the outer pipe sections.
