Cross Island Line CR105 in Singapore

Large diameterTBM with accessible cutterhead used in Singapore

The tunnelling length is 3,157 m with the minimum turning radius of 460 meters, the maximum overburden of 60 meters, and the maximum water and earth pressure on the axis of 5.25 bar. It travels through mixed ground with maximum uniaxial saturated compressive strength of 185 MPa. The tunnel passes beneath the runway of Changi Airport and thus requires strict settlement control. The TBM CREC 1108 supplied by CREG is the first large-diameter slurry TBM with accessible cutterhead in Singapore.

Project Background

As the first CRL in Singapore, the project has received extensive attention from local society and mainstream media outlets. It is the first tunnel project constructed by large diameter TBM in Singapore. It will serve the existing and future developments in the eastern, western and north-eastern corridors connecting major hubs including Jurong Lake District,Punggol Digital District and Changi, and helps Singapore to realize the long-term vision of reducing car usage
