A quieter Hydrofraise® for the Thames Tideway Tunnel

16 November 2017 - Projects update and handover - United Kingdom

It’s a first! Within the framework of the East works package on the Thames Tideway Tunnel project, currently being implemented by a joint venture composed of VINCI Construction Grands Projets, Bachy Soletanche (VINCI Construction) and Costain, since late summer 2017 an electric Hydrofraise® has been at work creating the walls of the shafts at the Chambers Wharf, Deptford Church Street and King Edward Memorial Park sites.

Developed by Soletanche Bachy, this new Hydrofraise® is more environmentally-friendly and very much quieter – the diesel motor replaced by an electric motor –, thus minimising the disruption affecting those living near the worksite.

Reminder: the East works package concerns the construction of two sections of tunnel (5.5 and 4.6 km) and five large shafts, for the rainwater and wastewater of East London. Handover is scheduled for 2023.
