The West Gate Tunnel Authority has completed construction on a noise mitigation and tunnelling hub shed in Yarraville, as the project gets ready to begin tunnelling.
The shed will attempt to keep noise and dust at a minimum for nearby residents and businesses, while 1.5 million cubic metres of rock and soil is excavated to build Melbourne’s alternative to the West Gate Bridge.According to a West Gate Tunnel Authority statement, over 12,000 work hours have gone into building the 180 metre long and 90 metre wide shed.
“It will be connected to the tunnel by a conveyer system that will be 15 kilometres long by the time tunnelling comes to an end,” the statement reads.The West Gate Tunnels second tunnel boring machine (TBM) Vida has now arrived in Melbourne. Both TBMs are now being assembled with Bella to launch mid-year and Vida to follow afterwards.”
Rock and soil will be taken from underground on the conveyer to the launch site for the tunnel boring machines, over the top of Somerville Road on covered conveyer, and then into giant bins before being trucked away.“The conveyers will move at 12.6 kilometres per hour and at the peak of activity will move 9000 tonnes of rock and soil a day,” the statement reads.
