11:00 Case Study – Bearing Replacement Project and Key Takeaways

The Central Queensland Coal Network (CQCN) contains many bridge structures built over the last 50 years, most of which have precast concrete girders on elastomeric bearings, many of which are reaching the end of their serviceable life. There are also issues with bearings on more recent structures being pushed out due to cyclical movement of the superstructure.

Current bridges designs include provision for jacking to lift the bridge deck in order to replace bearings, however older structures were not designed with this foresight and jacking these structures evenly presents an engineering challenge. With many different bridge designs on the CQCN, each bridge will require individual assessment and tailored jacking support framework.

The first bridge jacking operation to be carried out by Aurizon is on the Merinda section of the Newlands Line, just North of Bowen, Queensland. In this session, Brian will discuss the issues with bearings and bearing replacement on the CQCN generally and specifically with the bearing replacement project on the Newlands Line over the Bruce Highway.
