Hongkong-Zhuhai-Macao Bridge (HZMB) | Transitional structure, China


ロケーション: Hongkong, 中国

  • East and west transitional structures with tunnel entrances and breakwaters
  • 300-meter long side walls with up to 56-meter wide ramp structures and a wall thickness of 2.50 meters.
  • 6 lanes into the tunnel portals with a longitudinal gradient of 3 %
  • Separation of the directions of traffic through reinforced concrete walls of up to 15.50 meters which serve as supports for the roofing

The 35 km long Hongkong-Zhuhai- Macao road connection is located in the area of the approach flight path of the Hong Kong International Airport, Chek Lap Kok, in an underwater tunnel. This 6 km long immersed tunnel had already been successfully built with PERI know-how – the shell construction for the east and west transitional structures was the next stage to be completed. For this, two artificial islands were created in the southern Chinese Pearl River Delta. 6 lanes lead into the two tunnel portals with a 3 % longitudinal gradient.

PERI played a decisive role in realizing this once-in-a-century structure; tunnel entrances and breakwater were extremely challenging due to maintaining the highest quality requirements. The formwork could be easily moved and provided the best possible safety and first-class architectural concrete quality. We came to appreciate the professional engineering, service and the striving of the PERI engineers for perfection.


  • Fast, safe and simple execution with mobile portal wall formwork carriages which can work independently, using system elements from the VARIOKIT engineering construction kit, the VARIO girder wall formwork systems and SK tie technology
