MISSISSAUGA, ONT. – As a first project in Canada, the project team used an innovative engineering method called ” the Verona system to create a concrete passage under the Lakeshore West train tracks at the Port Credit GO station.
The passageway, also known as the push box, will be the tunnel through which future light rail vehicles will enter and exit Port Credit GO Station once the Hazel McCallion Line is operational. The technology employed ensured operations could continue on the Lakeshore West Line.
Preparatory work for the drawer included shoring and excavating the east side of Port Credit GO’s south parking lot and installing the thrust block and starter plate used in the drawer’s installation, according to a press release.
Recent work on Port Credit’s drawer included lifting the final 30 meters, removing four rows of micropiles and excavating more than 5,000 cubic meters of soil from inside the drawer – the equivalent of two Olympic-size swimming pools.
At 46 meters, the drawer is as long as three train locomotives and features a bulkhead that effectively separates northbound and southbound trains. The box weighs about 6,000 tons.
Teams have also made progress with concreting the platform level slabs from the drawer and are now working on the walls up to street level. The specific work includes provisions for mechanical and electrical systems, future elevators and a future tunnel ventilation system.
To date, more than 2,500 cubic meters of concrete have been poured for the service and platform levels of the Hazel McCallion Line’s future Port Credit Station.
