ABSTRACT:
A cable duct is provided for cables to be laid along walls or tops of subterranean tubes, ducts, etc. for the transport of water, energy, data, optical fiber cables, etc. The cable duct is installed in the tube from a surface through access shafts and fixed to the duct. The cable duct is formed by cable duct body elements, disposed one behind the other in a longitudinal direction, connected to one another at the ends thereof such as to be pivoted relative to one another at a lateral angle about a lateral pivot axis. Each of the body elements is formed by two cover plates and connected to one another by a web. Laterally open chambers are disposed on both sides of the web for housing the cables. The chambers are sealed by edge cover strips forming two closed longitudinal chambers with the connected angularly adjustable body elements.
