Hong Kong Trunk Road T2 and Cha Kwo Ling Tunnel

The project, a 3 .4 km of dual two-lane trunk road, in which 3.1 km is in the form of tunnel, constitutes the middle section of Route 6, connecting to the Central Kowloon Route on the west and the Tseung Kwan O – Lam Tin Tunnel on the east will be built upon the collaboration of the employer - Civil Engineering Development Department,

the consultant - Hyder-Meinhardt Joint Venture and the contractor - Bouygues Travaux Publics. Upon the completion of Route 6, the journey time between Yau Ma Tei to Tseung Kwan O during the peak hour can be significantly reduced from 65 minutes to 12 minutes.

Project Features

- 2 x 14m diameter slurry TBMs used in the project can cope with the complex ground condition within the tunnel lining.

- Automated devices such as “Robotic Arms” , the real - time monitoring system “MOBYDIC” (instrumented disc cutters) will be adapted in the construction of tunnel to improve the site safety and enhance the productivity.

- The first - time application of accessible cutter heads in Hong Kong allow workers to change worn out cutters at atmospheric pressure, which minimize the safety and health risk of decompression.

- The Design for Manufacture and Assembly (DfMA) approach will be applied for the construction of the internal structures. Installation of the prefabricated segments of service gallery, OHVD and cross passage can improve the tunnel logistic, safety and environment on-site.

- A 3.6m diameter slurry TBM using pipe jacking method is applied for the construction of cross passage as the precision pipe brake and thrust frame system can ensure effective pipe jacking and waterproofing.

- The Electrical and Mechanical (E&M) equipment will be installed using Multi trade Mechanical Electrical Plumbing (MIMEP) method.
