Upon inspections by Irish Rail, significant subsidence of a railway embankment near Foxford was discovered.
Remedial works were required to stabilise the railway line, consisting of a sheetpiled wall for 160 metres on both sides of the railway line. The approved piles were imported from Asia in 16 number containers into Dublin Port and hauled by road to Foxford Station. The contract was completed entirely with the company’s own plant and resources. The main equipment consisted of a piling rig compromising of a Movax SPE 50 piling hammer fitted on a Case CX210 25 tonne tracked excavator, specially fitted with rubber tracks for railway work. The piles were hauled to the remote site location using two atlas 1504 rubber ducks with rail wheels and tilt rotating encon hitch & McCabe grab towing two 5m x 20TN rail trailers. The piles were loaded at Foxford station by a Case CX160B excavator fitted with rotating grab. The piles were driven to depths of between 7 metres and 13 metres The piles were supported with a waler beam on both sides and tied across using 40mm threaded bars at 4.5 metre centers. The works were carried out at night during TIII possessions with the railline remaining operational each day for passengers and freight traffic.
