FIELD: tubular cable conduits for placement of subterranean cables. ^ SUBSTANCE: cable conduit device contains flexible structure of internal cable tunnel and is built in such a way, that a cable is contained inside the cable conduit. Flexible structure is composed of a separate sheet of flexible material in form of stripes, which are connected along their longitudinal edges to define the channel, through which cable may pass in longitudinal direction, through structure of internal cable tunnel between layers. Adjacent layers have varying width between longitudinal edges, as a result of which the wider layer projects to the side from the narrower layer to create open configuration relatively to the channel. Flexible insert for insertion into cable conduit contains flexible material, having base threads, formed of polyester and filling threads made of nylon. Flexible structure in one of variants contains textile material. ^ EFFECT: creation of dividing device which ensures improved usage of space inside the cable conduit. ^ 7 cl, 8 dwg |
