Elsfleth level crossing - trough structures incl. special civil engineering, ground improvement, underground cable construction & noise barrier
The new Elsfleth level crossing (lot 2) is being built as a replacement structure parallel to the existing structure. The new swing bridge will be connected to the existing route via trough structures and, further along the route, via embankments. Lot 3, which was awarded to EINW, includes the construction of the trough structures founded on piles and the construction of mortared vibrated tamping columns, which serve as ground improvement for the subsequent embankments.
The contract includes the following main construction services:
- Construction of 2 U-shaped trough structures, south side (760 m) and north side (230 m) with wall heights of up to 7.50 m and block lengths of up to 50 m
- Structural concrete for the trough structures approx. 26,700m3
- Reinforcement for the trough structures approx. 6,000 tonnes
- The trough structures are founded on 2,092 deep Franki piles (D=60 cm)
- Construction of approx. 22,000 m of mortared vibrated tamping columns to improve the subsoil of the embankments
- Construction of 3 noise protection walls on the north side (875 m² highly absorbent aluminium walls on one side)
- Construction of a permanent sheet pile wall on the north side (1,470 m²)
- Construction of a temporary sheet pile wall on the south side (580 m²)
Special features of the project:
- The preliminary earthworks are being carried out by third parties
- Parallel work by third parties on the abutments, bridge piers and railway overpass in a very confined space
- Mass transport via narrow construction roads
- Z. In some cases, work has to be carried out in the immediate vicinity of the operating track
The project will run for around 28 months from February 2026 to June 2028 and will be realised by our Civil Engineering department together with a consortium partner.
