Duppers Embankment Case Study

Problem – We were called to an embankment slip on a Friday afternoon, where the track had dropped & moved laterally by approx. 6”. Network Rail required a 800m access road to be constructed to get to the site, which involved a 1:4 gradient across very wet ground. A 50m x 3m high gabion wall was to be built & approx. 4000t of stone to be placed behind the gabion wall to re-profile the embankment.

Solution – We immediately started work on the access road, with our material suppliers/local quarry working throughout the night & weekend to supply the stone for the road, enabling machines to get to the site by the Monday. 24 hour working continued whilst the foundation & gabion wall were constructed & embankment re-profiled using a long-reach excavator placing stone that was delivered during the day. We also carried out track & embankment monitoring throughout until site was handed back to NWR.
