Work towards rail bridge foundations has now commenced in an inner Melbourne suburb.
Thirty-four piles (deep concrete foundations to support the rail bridge) are being bored at the Toorak Road site in Kooyong.
Piling rigs and cranes have been at work on the site of the level crossing removal project. A piling rig is a specialist piece of equipment with a high mast that enables it to dig deep into the ground.
The piles at Toorak Road will be up to 20 metres deep and 2.1 metres in diameter. The locations of the piles were determined after geotechnical investigations were conducted in late 2018 and early 2019.
Once the piles have been bored, cranes will lift a steel cylindrical ‘cage’ into place to reinforce the pile, with each piling cage weighing between 9 tonnes and 12.5 tonnes. The hole is then reinforced with steel and concrete.
“This process creates secure foundations and ensures safety and stability of the rail bridge,” according to a Victorian government statement.
