Restricted access mini piles for slab foundations to protect sewers intersecting the new railway line within Surrey Quays Station, Rotherhithe.
In Transport for London’s £10 billion investment programme, the East London line (originally part of the London Underground network) is being incorporated in an overall line to open in 2010 as the London Overground East London Railway. This will create a major orbital railway linking London’s suburbs.
Abbey Pynford were employed in their capacity as piling and ground engineering specialists by Bachy Soletanche Limited to work on the East London line extension at Surrey Quays Station.
"The station was full of contractors. We had to work extremely carefully around the rail system teams who were replacing the track. We had to pump grout to our piles over a 100m distance from a silo up on the overbridge, clear communication was vital to ensure a consitent supply to the piles down on the track"
-Anna Freeman, Contracts Manager
Abbey Pynford constructed piled foundations for a new slab to protect existing sewers that run below the tracks and also for temporary works to support the railway cutting. Over 100 piles were installed each of 450mm diameter to a depth of 14m. The piles were cased to 7m depth due to there being unstable ground conditions. The piles for the temporary works were installed as a contiguous piled wall and also a secant piled wall.
