Description
Transport for London (TfL) has identified that cuttings CTS 7 and CTS 8 between North Acton and Hanger Lane require remedial works to stabilise the cutting.
The combined length of the cuttings is approximately 1100m.
The assets are susceptible to pore pressure levels (the pressure of groundwater in the soil or rock) and displacements and are considered a high risk.
Due to the increased number of prolonged rainfall events over the recent years, soil pore pressure build up has become more common and the asset is at greater risk of failure.
In 2017, TfL Engineering produced a detailed design for remediating the asset which consisted of;
Discrete Bored Piles
Discrete H-Piles
King Post Wall
Asset drainage
Re-grading
After the detailed design was completed, the business decision was to pause the project due to funding constraints faced by the business.
Due to the criticality of this asset and the continued deterioration of the cutting, the project has been reinitiated.
