A no-dig storm water pipe scheme has been successfully completed on the site of a new large community housing development in Aylesbury, Buckinghamshire.
The 23 metre crossing could not be undertaken by conventional open-cut method as overhead power lines prohibited the use of ground excavation equipment. FP McCann supplied a DN450mm precast concrete jacking pipe which was installed using a guided auger boring trenchless technology, typically utilised in deep pipeline drives.
Trenchless work is far less intrusive than the traditional open-cut method of pipe laying and is particularly suited to areas where utilities, water courses or transport infrastructure has to be crossed. From the construction of a 5-metre deep shuttered drive and reception shaft, to the piloting of the tunnel and main auger drive, the scheme was completed on time and within budget.
