Eglinton LRT – Cedarvale Station SEM and SOE

Eglinton LRT – Cedarvale Station SEM and SOE

The Eglinton LRT Cedarvale Station required the new structure to pass below the existing TTC subway below grade. HC Matcon Inc. (HCM) was contracted by the Crosslinx group to perform segmental excavation method (SEM) and support of excavation (SOE) below the existing subway tunnel. HCM performed the detailed excavation and the installation of dry mix shotcrete in 6 galleries for the phased installation of structural needle beams to support the tunnel above.
HCM’s SEM work involved excavation in 1.1m sections, installation and stressing of temporary supports, and installation of accelerated fibre-reinforced dry mix shotcrete for the walls and base slab. Due to strict movement tolerances of the tunnel above, a unique prestressed waler incorporated with shotcrete shoring was implemented. Special design and constructability considerations were coordinated with the designer to ensure safety during excavation. HCM installed a waler and tie-rod system that was prestressed from between the walers to achieve the deformed shape required by designers.
Due to HCM’s knowledge and experience with shotcrete and associated applications,
this unique project was executed successfully and to the satisfaction of the project
team.
