Bauvorhaben: Sanierung und Erneuerung Hauptsammler Ost

TENDER DESCRIPTION

Starting at the rain overflow basin RÜ27, the main collector East will be rehabilitated over a distance of 1,067 m using the trenchless method with GFK pipes. The manholes in this area will be renewed. The old manholes for the Salzbach stream and the main collector will be filled up except for the inlet to the Salzbach. Some manholes will be dismantled to create space for new manholes. Instead of the cutting (slip) railway crossing that is filled in at the end of the measure, a new railway crossing at right angles to the tracks with a length of approx. 127 m is to be constructed using a DN 1600 launch (driving). From the new crossing at manhole 44927, the alignment will be guided via a curved launch of 352 m parallel to the tracks to manhole 42225, where it will be connected to the existing DN 1500. Along the newly planned alignment, chainage will be established starting at manhole 42225. All stationing references relate to this design chainage. The measure includes: - a total of 13 new manholes in high-performance concrete - 2 sewer pipe jacking drives STB DN 1600, 127 m and 352 m Microtunneling with flushing conveyance and compressed-air sealing - 1,067 m GFK rehabilitation…
