Method installing a duct, device for carrying out said method, and a tape-shape element for use with said method
First Claim
1. Method for installing a duct, a longitudinal member being present along the section over which the duct is to be installed, the longitudinal element present being utilised as a guide for the duct to be installed, and the duct being propelled, characterised in that a tape-shaped element is formed around the existing longitudinal element during propulsion into a duct closed all around, by coupling to one another coupling means present at the longitudinal edges of the tape-shaped element.

Abstract
Method for installing a duct, a longitudinal member being present along the section over which the duct is to be installed, the longitudinal element present being utilised as a guide for the duct to be installed and the duct being propelled, a tape-shaped element being formed around the existing longitudinal element during the propulsion into a duct closed all around, by coupling to one another coupling means present at the longitudinal edges of the tape-shaped element.
The invention offers a simple solution, on the basis of a tape-shaped element, of forming, around a (copper) telecommunication cable already present in the ground, a duct for including optical-fibre cables, without it being required to interrupt or remove the existing cable.
