We will first dismantle old pipes by the end of February 2025. We will then lay around 1 kilometer of new pipes with a diameter of up to DN400 for district heating and gas under the Neckar in Heilbronn. These pipes will be installed in the culvert structure, which lies deep under the riverbed.
What looks very unspectacular on the isometric drawings is a considerable challenge in practice: all the material and equipment must be lowered through a narrow opening of just 1.2 x 1.5 meters to a depth of 17 meters. From there, everything will be brought into the approximately 240 meter long pipe with a diameter of just 3 meters and welded on site. Precise planning, a smooth process and a well-thought-out assembly concept are crucial here.
