Application of self-drilling anchor bar in subway

It is understood that Sydney’s metro railway  runs through two purpose designed and built tunnels.

As of November 21, More than 11 million customer journeys have been made on the Metro North West Line, with Sydney’s new driverless trains travelling over 1.7 million kilometres – or 42 times around the equator.

In its first five months of operations, the new metro has ramped up to meet key milestones and is now carrying more than 75,000 people each weekday.

Self drilling anchor bar  used in tunneling can improve the stability and load bearing characteristics of rock mass. Under the circumstance of weak and broken rocks, self drilling anchor bar technology is an ideal anchoring system for supporting to prevent tunnel collapse, rock deformation, and ensure construction quality and the safety of workers. Sinorock self drilling anchor bar has been widely used in numerous metro railway projects. Due to the reliable products and strict quality control, Sinorock  has won a general recognition of our tunneling industry clients.
