The Brisbane North South Bypass Tunnel is a road tunnel, 4.7 kilometre long, two tubes, bored. It is a bypass road to relieve the city's bridges.
MSD received an order to supply sub-assemblies for the segment fabrication for the Brisbane tunnel construction project in Australia. It includes the following scope of work.
A segment carousel system consisting of:
- Rail system S49, oblique cut 45°, incl. thrust beam guide
- 1 working line, 4x curing line each 62.5 m
- 4 repair tracks each 7.5 m
- Working line covered with stud plate.
- 2x rail systems S49 for SB each 22.5 m
- 2 transfer tables (10 m/min),1x with track gap closure in front of curing chamber (with hydraulics), 1x without track gap closure after curing chamber (without hydraulics)
- Thrust beam for working line 1 + working line 2 (62.5 m; 20 m/min)
- 4x thrust beams each 62.5 m (5 m/min)
- 2 roller shutter gates for concreting chamber
- 8 swinging gates (automatic) for curing chamber
- l vibrating table in concreting chamber
- 2 pillar slewing cranes in working line
A reinforcement cage transport system consisting of:
- Craneway / gantry
- Lifting gear with grab:
- Cage store / buffer / feeder
- Controls
- One travel-out line consisting of:
- turning device 180°
- rails / track segment transport (gauge 1500 m)
- Longitudinal transport segment (1+6 standing areas, 6 wagons per 10t)
