Australia’s largest road infrastructure project being a 6.7km toll and 3km dedicated busway road network featuring twin 5.1km tunnels connecting Brisbane city with the Northern Suburbs and airport precinct.

PROJECT REPORT SHEET: PRECAST CONCRETE ROADWAY ELEMENT GROUTING

PROJECT COMPLETION: DECEMBER 2011

CLIENT/END USER: THEISS JOHN HOLLAND JOINT VENTURE

APPLICATION

WHERE WE USED BLUCHEM HE80

Grouting of all joint gaps of 20mm and 90mm between precast concrete roadway elements and between the elements and the segmental tunnel.

WHY WE USED BLUCHEM HE80

The project specification called for a low shrinkage, non metallic, non-corrosive grout that was pumpable into a 20mm wide x 540mm deep gap.

Pre-construction trials showed that the specified strength of 42MPa could be achieved using BluCem HE80 within 4 to 5 hours. This allowed rapid tunnel cycle times.

FEATURES

Automated batching plants

Fast setting

High flow non shrink

BENEFITS

Fast advancement of works

Reduced labour costs

Minimisation of dust in the tunnel

Controlled quality outcome

SUMMARY

The customer benefited from the technology offered by the BluCem HE80 grout where the tunneling program and roadway construction was within expected construction timetables. Through support from Bluey Technologies’ engineers the client operated the batching facilities on each TBM in a safe, efficient and environmentally acceptable manner.

The availability of the BluCem HE80 grout in the tunnel allowed the customer to utilise it’s unique strength gain properties to solve numerous other issues associated with TBM tunneling activities.
