Fixing Catenary to Masonry Lined Tunnels

The traditional method of using slow curing mortar was considered inefficient by project managers. The risk of ‘project overrun’ and potential added cost of line closure to cater for the project overrun were considered major problems and were to be avoided completely with the help of VJT.

The VJ Technology technical team managed to value engineer a system that allowed the brackets to be fixed in less than 10 minutes, compared to the 1 hour per bracket using the original system – 600% more productivity.

Therefore, the risk of project overrun was minimised and associated line closures were not a problem throughout the duration of the project, and extensive testing was undertaken to prove the system had sufficient capacity, durability and safety precautions for the application.
