Can't Stop- Addicted To The Big Dig

Network Rail does Not quit. Not because of Two underground tunnels.

Exposing some openings underneath Lime Street Station in Liverpool stopped the platform extension there in a hurry.  As spoil piled up on one side of the tracks, some nervous hand-wringing began.  What dumper can drive over two huge tunnels?

The project

Network Rail had ground to a halt. Which is a problem, because Network Rail does not, as an organisation, tolerate grinding to a halt. Especially when that stoppage of work includes a platform upgrade at a key hub in the North – Liverpool’s Lime Street Station. But in June of 2017, the excavation for the platform lengthening was stopped and there was nothing they could do about it.

You see, the platform at Lime Street was supposed to be lengthened for new trains. Originally, two diggers had been operating at night only (for minimise disruption) to move the spoil out the door. However, one of the tunnels they were using for infill had been flooded, so the spoil now needed to be moved over the tunnels and to a new location.   The pile of excavated sand on the track side was getting higher and higher, but had nowhere to go. Sure, the tunnels were set to be filled with concrete in a month’s time, but the project manager couldn’t just sit back and wait for that to be poured and set.

The solution

Desperate for any solution to move some spoil quietly and quickly, Coveya was called to site in early June. Our operatives quickly surveyed the issue and provided a recommendation that three Easikit 600 conveyors be positioned to convey the spoil over the exposed tunnelling.  We also included some custom-made wheeled frames so the system can be easily re-arranged on site as the extension continues. Just three days later, a 7.5 ton truck appeared on site and the conveyors were in position right away. Our package included the required silenced generator, so the Network Rail team simply plugged them in and fired them up! Within a day, the pile of spoil was carried away and work had restarted with a full head of steam.

We came back to site to check on the conveyors a few weeks later, and the team did have a significant complaint- they couldn’t load them fast enough with only one digger! They’ve reconfigured their schedule as well, so the digger is operating in the evenings to create a large pile of spoil, and then the quieter conveyors are running during the day to move it all away.  This helps to minimise noise pollution from the dig.  Air pollution has also been reduced during the day, as the conveyors are completely electric, with no fumes or exhaust.  The project manager assured us that the conveyors have helped to keep the project on schedule for completion in October. 

Why not let Coveya see how much time and money you could save?
