Stabilising an embankment with a contiguous piled wall
Aarsleff Ground Engineering have completed on site installing a contiguous piled retaining wall for a new train maintenance facility in Scarborough.
The new train care facility will provide maintenance services including fuelling for trains operating to and from Scarborough. The facility will also be able to cater for 13 new five carriage trains to be phased into service over spring 2019. These trains will provide an additional 700,000 extra seats per year for outgoing and incoming trains into Scarborough station. An additional 15 jobs will also be created as part of the new facility.
Aarsleff were awarded the contract for the embankment stabilisation by Graham Construction, who were working in partnership with Network Rail.
The embankment required stabilisation to prevent the risk of collapsing onto the North East Coast mainline. Working closely with Network Rail and Graham Construction, Aarsleff utilised their Klemm 702 rig to install the 24no. cased auger contiguous piles. The Klemm 702 features a compact design and a low bearing pressure, which allowed Aarsleff to minimise the risk of the embankment collapsing whilst carrying out the works. The steel reinforced cages for the piles were also cut into shorter lengths than standard to prevent further risk of the embankment collapsing.
