Project Difficulties and Restrictions

The project required bearing piles to be installed next to the Olympic park footbridge, to widen the existing bridge. The piling platform which was located next to the existing bridge and an adjacent canal, was restricted in size and could only be accessed by a small piling rig under 30 tonnes. 

The ground conditions required the piles to be fully cased or bored under Bentonite support fluid.
 

The Martello Solution

Martello’s MP5000 series rotary rig was light enough to track down the existing access ramp onto the piling platform. 
Martello were able to successfully install the 900mm diameter piles to the required design depth, by digging the piles under bentonite, and allowing the client to achieve the diameter and loading capacity required by the design, without the necessity to revert to smaller diameter piles, which may have been necessary with other small light weight piling rigs.
 

Specific Project Features

The works consisted of the construction of 3No 900mm diameter piles to enable the widening of the footbridge and the development of the stadium. 

A small-scale Bentonite farm was assembled at the top level of site, to supply Bentonite drilling fluid to the bore, and treat it after use.
 

Future Potential

The compact and lightweight nature of the MP5000 rigs allows for easy access to constrained sites enabling large diameter piles to be installed.
