Australian cooling towers manufacturer Lakeside Cooling Towers has been working to keep twin tunnel boring machines in operation more than 20metres underground.
The Westgate Tunnel project in Victoria involves drilling two 4km and 2.8km tunnels deep below the surface.
A massive shed was recently built in Yarraville to handle the 1.5million cubic metres of rock and dirt excavated by the drilling machines.
But they require constant cooling as they bore their way through rock and soil, with Lakeside Cooling Towers providing critical water cooling on a round the clock basis.
The 61-year-old firm is supplying MA30 induced draft cooling towers for the two drills – named Bella and Vida – as well as the 5m raised platform they rest on, 100m³ storage tanks, circulation pumps, and automatic dosing equipment.
The CPB and John Holland Contractors Joint Venture project is Lakeside’s second tunnel boring venture with John Holland.
