Central Kowloon Route (CKR) – Central Tunnel, Hong Kong

 

Central Kowloon Route (CKR) – Central Tunnel, Hong Kong

 
 

Dextra played a pivotal role in the construction of the Central Kowloon Route (CKR) – Central Tunnel project in Hong Kong by supplying Fortec+ couplers, along with steel rock bolts, expandable friction bolts, umbrella pipes, and post-tensioning bars for tunneling works. These mechanical rebar couplers were integral in ensuring strong and reliable connections within the road tunnel structure, meeting the stringent requirements for safety and durability.

The CKR, a major infrastructure project aimed at improving traffic flow across Kowloon, required advanced construction techniques. Dextra’s Fortec+ couplers, used in locations such as precast panels, tunnel access points, and driveways, contributed significantly to the project’s structural integrity and long-term performance. The Fortec+ system includes a rebar preparation process in which the threaded bar end is proof tested with a tensile load, ensuring non-destructive testing within the elastic zone of the reinforcing bar.
