Hongkong-Zhuhai-Macao Bridge (eng.)

Hongkong-Zhuhai-Macao Bridge (HZMB), China - The 180 m long tunnel elements are cast in eight individual segments each 22.50 m long – monolithic, without ties and in compliance with strict dimensional tolerances.
Hongkong-Zhuhai-Macao Bridge (HZMB), China - The internal formwork moves hydraulically over the launching beam into the reinforcement cages.
Hongkong-Zhuhai-Macao Bridge (HZMB), China - A total of 33 tunnel elements will be produced using two production lines: each 180 m long, 38 m wide, 11.40 m high and weighing 72,000 t.
Hongkong-Zhuhai-Macao Bridge (HZMB), China - The finished tunnel tubes with lengths of 180 m are moved from the field factory into a dry dock, sealed with bulkheads and lowered gradually to reach sea level.
Hongkong-Zhuhai-Macao Bridge (HZMB), China - Realization of the three-cell cross-section is achieved using the incremental launching method by means of three sets of tunnel formwork as horizontal moving device.

Hongkong-Zhuhai-Macao Bridge (HZMB), China

  • longest underwater tunnel in the world, almost 45 m below sea level
  • part of the 35 km long road connection between Hong Kong and Macao/Zhuhai in the area of the approach path to the Hong Kong International Airport Chep Lap Kop.
  • construction period:  2012 to 2015
  • tunnel length: 6 km


Production of 33 tunnel elements which are each 180 m long, 38 m wide and 11.40 m high

  • maximimum deviation of +/- 2 mm
  • hydraulic shuttering and striking
  • delivery of the formwork solution in a very short amount of time
  • life-span of at least 120 years required


China Communications Construction Company Ltd. (CCCC)


  • production of the bottom plate, outer walls and slabs without ties
