Abstract:
A method for installing a duct in the ground, proximate a longitudinal element, the method comprising the steps of:moveably securing a coupling device to the longitudinal element such that the coupling device is moveable along the length of the longitudinal element, and fixedly attaching the coupling device to an end of the duct; pushing the duct such that it advances in a substantially parallel manner with respect to the longitudinal element, and causing a fluid under pressure to flow through the duct towards and out of the end of the duct to which the coupling device is attached, wherein the coupling device includes a coupling piece having two connectable parts which are disposed about the longitudinal element, an insertion opening in which the end of the duct is immovably connected to the coupling device, and an elongated guide opening through which the longitudinal element is moved during pushing of the duct.
