Tyne Tunnel

The SCL sections were incorporated at the cut and cover sections to increase the speed of the project programme

ByrneLooby were responsible for the independent checking of the temporary lining of the Sprayed Concrete Lining (SCL) sections of the award winning New Tyne Tunnel.

The New Tyne Tunnel consists of an immersed tube tunnel under the River Tyne with cut and cover tunnels on the approaches. SCL sections were included at two locations where existing gas and sewer mains cross the route.

The temporary lining consisted of an umbrella pipe arch vault and sprayed concrete with arch ribs. Our FEA check of the installation and loading of the lining confirmed its structural adequacy ahead of installation of the permanent cast in situ concrete lining.
