Mini borer makes debut
A MINI tunnel- boring machine on Railway Parade in Bayswater made its debut yesterday as part of the $1.86 billion Forrest field-Airport Link project.
The rail link will deliver a new rail service to the eastern suburbs of Perth – with three new stations at Redcliffe, Airport Central and Forrestfield. The link will come off the existing Midland line near Bayswater station and run to Forrestfield through twin tunnels.
The machine will tunnel under the Midland line and finish on Whatley Crescent, a distance of 108m, installing two pipes side by side.
It is 3m long and weighs about 7 tonnes. The cutter head diameter is 1.5m.
After City of Bayswater approval, a 50m- wide section of Whatley Crescent was closed between Anzac and Newton streets from June 14 for up to eight weeks, as part of works for the relocation of a main drain.
Maylands MLA Lisa Baker said the tunnel was a “mini- me” version of two large machines, Grace and Sandy, which arrived at Airport Central station in May.
“It is like the tiny offspring of the huge tunnel boring machine,” she said.
“This is all being done with the mini boring machine because we have got water lines that have to be moved to make way for the line that comes in. “It is just the gateway that is a starting point for opening up the Bayswater redevelopment.”
Ms Baker said the Whatley Crescent closure was a small inconvenience for a major development.
