WESTENBRUNNENBACH CULVERTS THROUGH RAILWAY EMBANKMENT
Treuchtlingen, Germany
The planners originally envisaged rehabbing the array of culverts in the embankment carrying the railway over the valley of the Westenbrunnenbach river by laying precast reinforced-concrete pipes inside the old cross-sections and filling the cavities round the pipes with compacted sand. The specialist company that contracted for the work proposed an in-situ concreting solution instead. Doka then modified its Box Culvert system, which is designed for the cut-and-cover method, so that it could be used for single-sided forming and concreting. The system, which can use either Large-area formwork Top 50 or Framed formwork Framax Xlife, has the advantage that the culvert walls and top slab can be cast monolithically (fresh concrete pressure 50 kN/m²).
