Project Description
The Altrhein Siphon - a unique construction. The siphon consists of a concrete pipe with an inner diameter of 3.40 m and runs for a length of 408m at a depth of around 30m under the Altrhein.
Steel structures for the guidance of media lines for district heating (DN 700 VL and DN 800 RL), steam (DN 500) gas (DN 400), drinking water (DN 200) and condensate (DN 100) were installed in the siphon. The shafts for the start and target construction pits were designed as bored pile pits with underwater concrete bases. Since the construction site is located in the floodplain of the Rhine foreland, a mobile and modular flood protection was attached to the head beams of the construction pits.
The construction pits were concreted using a sliding formwork; the gate chambers monolithically connected to the shafts were conventionally produced in in-situ concrete construction.
The measure was carried out in the form of a working group of the companies Kassecker, Diringer & Scheidel, Sax + Klee, as well as the company Sonntag.
