Hinksey Flood Alleviation Scheme

Project Details

Client: Network Rail
Principal Contractor: Carillion Rail
Value of contract: £250,000

Description of Works:

This project in Oxfordshire involved the installation of both permanent and temporary sheet piles on both sides of the Great Western mainline prone to flooding. J N Piling Ltd engaged in the project over a series of visits.

112 No 7m long L604 temporary piles were installed to form a cofferdam on the western side of the site to enable de-watering of Hinksey Stream to take place in order for a new culvert to be constructed to reduce the risk of flooding. 6m long AZ26-700 permanent single piles were installed on both sides to form the headwalls for the new culvert under the railway lines. 

On the western side, both the temporary and permanent piles were installed using a Movax rig and on the eastern side the permanent piles were installed using a telescopic leader rig and variable moment vibratory hammer.
