| 摘要 |
The invention relates to a novel cable duct for cables, which are to be laid along walls or tops of subterranean tubes or ducts for the transport of water or sewage or similar, for energy data and information transfer, in particular, for optical fibre cables, whereby the cable duct may be installed in the tube from the surface through access shafts and fixed to the duct wall or top. The cable duct is characterised in being formed by similar, longitudinal cable duct body elements (10), arranged one behind the other in the longitudinal direction (rl), connected to each other at the ends thereof such as to be pivoted relative to each other at a lateral angle about a lateral pivot axis (as), each being formed by two cover plates (2, 2'), connected and held parallel to each other by a web (3), arranged in the middle. The laterally open chambers (20, 20'), arranged to both sides of the web (3), between the cover plates (2, 2'), provided for the subsequent housing of the cables (6), may be sealed to both sides by edge cover strips (51) with interlocking elements (52) along the longitudinal edges (51) thereof which interlock with corresponding counter interlocking elements (22) on the longitudinal edges (21) of the cover plates (2, 2') of the body elements (10) which are made from an elastically flexible material, to form two closed longitudinal chambers (200, 200'), from the connected angularly adjustable body elements, separated from each other by the webs (3) of each of the body elements (10), through which the cable duct (1) may be passed, embodied for the introduction of said cable (6).
