Feltham

The project required the installation of 6No 900mm diameter piles which were installed underneath the railway, within the confines of a 3.5m high x 3.5m wide flood arch,  and 20No 750mm diameter piles, to be installed at track level next to the operational line. 

The site restrictions significantly limited the size of the piling equipment which could be used for the project. 

Martello provided the MP4000 series rig to operate within the constraints of the flood arch to install the 900mm diameter piles. 

A low headroom MP5000 series rig was also provided to work at track level next to the operational line for the opposite abutment work. 

Martello were able to form the piles whilst the railway was still operational, preventing further disruption to the client. 

Martello were able to finish the piling works ahead of programme and completing the works two days before Christmas, allowing further works to be completed over the Christmas period.
 

A flood river had caused scour to the foundations, and partial collapse of a brick arched structure supporting the Reading to London train line at Feltham resulting in train diversions and delays.

The re-construction programme period was critical as the train delays were causing significant additional costs to Network Rail.
 

The Martello technique enables the installation of large diameter piles in restricted access conditions, allowing the foundations to be constructed before the demolition of a structure.
