<p>Method for installing a duct (2) in the ground, whereby a longitudinal organ (1) is already present in the ground near the route along which the duct (2) is to be installed, whereby the existing longitudinal element (1) is used as a guide for the duct (2) to be installed and the duct (2) is pushed into the ground with the aid of a fluid under pressure fed through the duct (2), whereby the duct (2) to be installed is coupled to the existing longitudinal element (1) by means of at least one divisible coupling piece (3) and whereby the coupling element is advanced along the existing longitudinal element (1). The invention also provides a coupling piece (3) for guiding the duct (2) along the longitudinal element (1).</p> |
