In Freiburg Dietenbach, a new district is being built for about 16,000 people.
As part of the external development measures, pipeline work for district heating, drinking water and groundwater must be carried out. The section of the route leads through Mundenhofer Straße, starting at Tel-Aviv-Yafo-Allee to the newly built energy center in the parking lot of the animal enclosure Mundenhof.Im construction site, several columns work in parallel or staggered behind each other.
The laying of the pipeline is carried out in an open trench. For the crossing of the Landwassergraben running to Mundenhofer Straße, a closed construction method is planned for the drinking water pipe.
Earthworks and pipeline works:
Excavation and restoration of surfaces in the area of the pipeline trenches: 6,400 m²
Excavation: approx. 9,400 m³
Pipeline construction: Groundwater PE DA560 – 920m
Drinking water DN 500 GGG – 840m
Drinking water PE DA 180 – 1300m (optional)
District heating – KMR DN 200 and DN 250, single and double pipe – 1,500 m
