The universal and versatile use of protective tubes
Urban roadsIn inner-city traffic areas, it is necessary to lay a double train of cable protection pipes at crossroads and underneath roads that lead into the city. A longitudinal cable protection pipe should also be considered for a "green wave" and a "speed funnel" on main roads.
The line connection of emergency call pillars to the motorway maintenance depot is usually one-sided, whereby the emergency call pillar opposite is connected through a spur line under the carriageway. A cable protection tube must be provided for this connection.
Traffic guidance systems
Traffic guidance systems with variable message signs can be found on busy motorways in conurbations. They are used to control speeds and prevent traffic jams. Here, cable protection tube systems are used for the necessary control lines.
For rapidly changing technical requirements for control and signal lines that are parallel to rail tracks, the use of cable protection tubes is recommended.
At signal-controlled intersections on federal or country roads, at least two cable protection conduit strings are installed under each street that joins the road. This method allows separate laying of power supply and control lines of the traffic light system.
Since the development of telephone, Internet, multimedia connections as well as television and radio systems in the future can hardly be predicted, the verifiable advantages of a cable conduit system should be taken into account for this area.
