Piling progress for treatment works upgrade

Sheet piling and shoring work for the upgrade of Old Whittington waste water treatment work in Derbyshire has been fast tracked using some innovation safety solutions.

The £15M upgrade of the Yorkshire Water facility near Chesterfield include construction of a below ground storm water overflow that will be equipped with three 8m long screw pumps. Support for the 25m by 15m excavation has been provided by 180 Groundforce HY6 lapped steel sheet piles that were installed using a Miller MS4 vibrating hammer fixed to the 23t Komatsu excavator by Piletec’s new VibroSafe quick-hitch attachment.

Lateral support for the excavation is provided by Groundforce Shorco’s Megabrace modular hydraulic struts and an HSK80 hydraulic prop in a single-frame propped cantilever configuration.
