Project Difficulties and Restrictions

The works had to be undertaken within limited access constraints to complete a 750mm diameter secant wall which would later, following the excavation, form a permanent retaining wall of the Acton Dive Under route.

Works required the construction of the secant wall in a 4.5m of headroom under Noel Road Bridge and elsewhere in 7m of working headroom under the OLE (Overhead Line Electrification) gantries. 
 

The Martello Solution

Martello’s low headroom capability helped complete the works in a more efficient manner, reducing costs, as the majority of the works were able to be undertaken during normal working hours and within the confines of the existing structures, thereby saving money and reducing the overall construction programme, without compromising safety.

Specific Project Features

Acton Dive Under is part of the Crossrail surface programme being delivered by Network Rail. 

Martello were contracted by Bam Nuttall to undertake two phases of work. The first being works under Noel Road Bridge and an OLE gantry. The second one being a return visit to complete the secant wall under another OLE gantry. All works at Acton Dive Under were taken in and around the goods yard and Great Western Relief lines.
 

Future Potential

Large diameter bearing piles and bored pile walls may be constructed adjacent to active railways during normal working hours.
