A 1.7 mile long conveyor network will remove over one million lorry movements for HS2’s construction in London
A new 1.7 mile-long network of HS2 spoil conveyors has been unveiled in West London, which will move over 5m tonnes of spoil excavated for the construction of HS2.
The use of the conveyor will remove the need for one million lorry movements from roads in West London, reducing traffic congestion and emissions in the local area.
HS2’s contractors, Balfour Beatty VINCI SYSTRA joint venture (BBVS JV) and Skanska Costain STRABAG joint venture (SCS JV), have collaborated to construct the network of conveyors which meet at the HS2 Logistics Hub at Willesden Euro Terminal.
The HS2 spoil conveyor has already begun operation and serves three sites
The conveyor network has three spurs, serving the Old Oak Common station site, the Victoria Road Crossover box site, and the Atlas Road site.
At Old Oak Common, HS2 Ltd’s station contractor, BBVS JV will use the conveyor to remove the 1.5m tonnes of spoil that is being excavated for the station box, the subsurface structure in which the HS2 platforms will be constructed.
Speaking about the commencement on the conveyor system, HS2 Ltd’s stations client director, Lee Holmes, said:
“This impressive network of conveyors means we are able to significantly reduce the impact of construction on the local area. Momentum on HS2 continues to build as the project nears peak construction, and systems like these conveyors are just one of the ways we are working to reduce carbon emissions in construction.”
The conveyor system includes sound barriers and a cover to prevent noise and limit dust dispersal
The final spur runs from a site on Atlas Road and will be used to remove spoil from the excavation of a logistics tunnel running from Atlas Road to Old Oak Common.
The conveyor will then be extended through the logistics tunnel and will remove material from excavation of the Euston tunnel, further reducing the impact on the local road network.
The HS2 spoil conveyor will also serve to remove waste from the giant tunnel boring machines that are to be launched from Northolt Tunnel East in later 2023.
The spoil materials will be repurposed at the Logisitics hub for redevelopment
From the Logistics hub, the spoil will be taken by rail to three destinations across the UK – Barrington in Cambridgeshire, Cliffe in Kent, and Rugby in Warwickshire – where it will put to beneficial reuse, filling voids which will then be used as a basis for redevelopment, such as house building projects.
To date, the Logistics Hub has processed over 430,000 tonnes of spoil, with over 300 trains distributing the spoil to its end destination.
The spoil conveyors are an integral part of reducing carbon emissions in HS2
Nigel Russell, project director, Balfour Beatty VINCI SYSTRA, said:
“As we work to deliver Britain’s new, high-speed railway, we are continually seeking new ways to reduce the carbon emissions associated with our operations.
“The conveyor belt is a key example of how we are doing just that; collaborating with our partners to put in place new, innovative solutions which not only reduce our emissions, but also reduce disruption for the travelling public and local community.”
James Richardson, managing director of Skanska Costain STRABAG Joint Venture said:
“SCS JV are proud to be part of the collaboration that constructed the carbon-friendly HS2 conveyor network, responsible for removing over 5 million tonnes of spoil.
“Moving spoil on the vast 1.7mile conveyor network means a million fewer lorry journeys, less disruption to local residents and businesses, and puts us on track to deliver our commitment to achieving net zero carbon.”
