Following a ceremony on February 1st the Channel Express, that is a Slurry TBM that was manufactured and shipped by CRCHI and created for a key water supply tunnel project in Singapore, was launched successfully.
As one of the key infrastructure projects of Singapore’s National Water Agency, the Singapore Tuas Water Reclamation Plant links to Jurong Island with the help of this project and through a sub-sea TBM tunnel. Crossing beneath the seabed for a long distance, the tunnel is due to encounter high water pressure, while it passes through mudstone, siltstone and sandstone for an extended part of the way and the TBM will deal with high rock strength. To add to this complex drive there are indications that there may be a fracture zone in the tunnel section.
Considering the characteristics of the project, the Channel Express TBM is equipped with advanced technologies such as:
- a high-pressure main drive seal
- jaw+roller two stage stone crushing
- synchronous bi-component grouting,
- slurry circulation anti-blocking system
Providing video monitoring of the main bearing and the digging chamber, will be the advantages of telescopic camera device, which is a first to be used in the Singapore tunnel project. Additionally, the intelligent excavation management system can monitor the excavation volume in real time.
