Merseylink’s construction teams are building three pylons to support the cable-stayed bridge. The initial pour is for the south pylon foundation and involves pumping 1,400m3 of concrete into the south cofferdam in a non-stop operation that will last about 27 hours.
The three pylon foundations will sit below the riverbed and will each be 4.5m high and be up to 22m in diameter.
Merseylink’s site agent George Houston said: “This is one of the biggest concrete pours that I’ve ever been involved with. We’re using a massive amount of concrete - over 600 truckloads just for the three pylon foundations. It’s an extremely technical part of the project and our teams will be working round the clock to get the job done.”
In total, approximately 127,000m3 of concrete will be used across the project - the equivalent of about 20,000 truck-mixer-loads of concrete.
