Project Difficulties and Restrictions

The scheme required Martello to install 40 piles at 600mm diameter to depths of up to 22m, to form new abutment foundations and a retaining structure. The bridge spanned over 4 live tracks, and although the site had no physical height limitations the piles were in close proximity to the train lines and hence subject to ALO working in certain locations.

 

The piles were required to be drilled under water and to be cased to full depth to assure the pile integrity.

The Martello Solution

The MP5000 series piling rig was well suited to the scheme and operating in low height mode was able to work effectively throughout the shift without impacting on the operation of Network Rail.

 

The piles were fully cased and the spoil retrieved could be periodically checked against the boreholes to validate the strata to determine the presence of coal seams or any mine workings. 

Specific Project Features

The existing access road bridge running over the live train tracks required to be reinstated, to cater for larger and more frequent traffic loads. 

 

The old bridge was to be lifted out and the new bridge assembled onsite and lifted in place onto new bridge abutments which were to be supported on 40no piles cast behind the existing bridge foundations.

Future Potential

Martello's compact rigs enable large diameter piles to be installed in restricted access sites where height restrictions also apply. The ability to fully case the piles allows variable strata to be easily dealt with.
