Protective strip
A protective strip is an area along the routes of roads , railways , high-voltage lines , pipelines or border systems in which building or walking, agricultural use and traffic routes are not permitted or only possible to a limited extent. Within the protective strip there may be structures that serve or do not hinder the actual operation of the route, for example noise barriers along motorways and high-speed routes , control lines and compressor stations along gas pipelines and pumping stations along oil pipelines, control and communication cables along railways, Buildings and trees under high-voltage overhead lines if a voltage flashover can be ruled out.
Pipeline operators fly over their route in Germany every day. Unregistered civil engineering work in the protective strip is immediately prevented by this control. When constructing routes from other network operators that run parallel to the pipeline, distances of different widths must be observed depending on the operator, the size and the risk of the pipeline. When pipelines are crossed, the pipeline operator checks the restoration of the cathodic protection . When railways are crossed, the rail transport operator has the crossing network operator measure the exact track position before, during and at certain intervals after the civil engineering work.
history
The following prohibition sign is already known from Roman water pipes in the Rhineland and similar facilities to Nîmes and Lyon in France:
"At the behest of the Emperor Caesar Trajanus Hadrianus Augustus, no one is permitted to plow, sow or plant within the space that is intended to protect the water pipe."
