At first glance, the planning challenges might not seem too onerous. However, on closer inspection, some very complex and technically demanding details have to be taken into account. Open pipes are pipes that are laid not in the ground but above the surface – the pipe and soil system is interrupted, so to speak. Influences such as temperature changes in the medium or the environment take full effect here. Forces caused by internal pressure – which cannot be transmitted into the ground via the pipe bedding – have to be controlled in some way, and it is in this context that terms such as position securing, interim management and protection against vandalism are often mentioned. On closer inspection, a task that initially seems simple can become a technically complex challenge.
