  • the present invention relates to a method and a device for pulling in particular optical fiber cables into protective tubes.
  • protective pipes for example made of plastic.
  • a bundle of such protective pipes has already been laid in the ground when creating a laying section, so that partly unused, that is to say empty, protective pipes are present in which the optical fiber cables now used are to be inserted.
  • These protective tubes are divided into several tubular sections because the optical waveguide cables are much thinner than the copper cables previously used. This is done, for example, by placing a bundle in such empty protective tubes smaller-diameter protective tubes or, for example, also an intermediate floor unit, which consists of two smaller-diameter protective tubes connected to one another by means of a web, can be introduced.
  • the latter intermediate floor unit can also be used to subdivide a protective tube already occupied by a copper cable by pushing this intermediate floor unit over the already inserted copper cable, so that three additional spaces are created, namely one above the intermediate floor for pulling in, for example, another copper cable and two. others in the form of the two side protection tubes for the insertion of fiber optic cables.
  • TZB L ATT It is therefore an object of the present invention to provide a method and a device for pulling in particular optical waveguide cables into protective tubes, in which or with which the pulling in of optical waveguide cables can be carried out in a simpler manner and over substantially longer distances, almost unlimited lengths, without that the fiber optic cables are subjected to an impermissibly high tensile load.
  • the optical fiber cable remains from the beginning on the belt webbing serving as a vehicle, since the drum pulling force is applied, for example, by hand or by machine to the cable drum. After a certain retracted length, it would be possible to cancel this external pull-off force, that is, if the friction force between Fiber optic cable and webbing is greater than the drum pulling force.

  • Optical fiber cable 11 is withdrawn from the cable drum 21 until its front end 24 is close to the node 22 within the tubular webbing 19 'and thus within the protective tube 12; the webbing 19 'and the optical fiber cable 11 lying thereon are introduced into the protective tube 12 over a short distance of, for example, one or more meters. The optical fiber cable 11 is thus over this initial distance - on the webbing 19 '.

  • the optical waveguide cable 11 lies closed and thus without load on the belt 19 or 19 ', so that it runs into the protective tube 12 as a vehicle without it being able to slip relative to the tubular belt 19'. Care is taken to ensure that the optical waveguide cable 11 comes to rest on the flat webbing 19 before the flat or rolling webbing 19 is inserted into the funnel 27 or directly into the protective tube 12.

Abstract

Dans un procédé pour passer des câbles en fibres optiques (11) dans des tubes protecteurs (12), on passe une bande (19) dans le tube protecteur (12) de manière à former un élément tubulaire qui est en contact avec une partie substantielle de la paroi inférieure du tube protecteur (12). Le câble en fibres optiques (11) est placé sur la bande (19), laquelle fait office de véhicule pour passer le câble dans le tube protecteur (12). Des câbles en fibres optiques peuvent ainsi être passés de manière simple et sur des tronçons de longueur pratiquement illimitée, sans être soumis à des contraintes de traction excessives.
