Gerrards Cross

During a previous contract, precast arched segments were being used to create a tunnel section within an existing Railway Cutting, to create land space above, for the construction of a new Supermarket.

During the backfilling operation, some of the tunnel segments collapsed onto the railway, blocking and closing the track for several months.

The remedial action on a subsequent project, required the construction of a tied back bored pile wall 900mm in diameter, and 23m deep, along the length of the tunnel, to allow the subsequent removal of the existing backfill material, in order that the tunnel segments could then be used as a permanent shutter to form a new concrete arched structure.

Martello Piling used their restricted access MP4000 series rig to construct a 750mm diameter bored pile wall where the access space was restricted to a platform just a few metres wide, and in the other areas 2 MP5000 series rigs were used, installing 10.0m of temporary casing and constructing 900mm diameter piles to 23.0m. The contract was scheduled to last approximately 6 months, and successfully completed approximately 3 weeks early.
