Tunnel portals and operation buildings for the Hong Kong-Zhuhai-Macao Bridge

The following images, photographs, illustrations, videos and media or "Tunnel portals and operation buildings for the Hong Kong-Zhuhai-Macao Bridge" include visual details and information about this product or case study.

The directions of travel are separated by 15.50 m high reinforced concrete walls. Supported on the walls is a steel structure that serves as a sun shield. The multi‑storey building is being built in the back of the tunnel entrance (top right in the picture)

On two artificial islands at both exits of the Hong Kong-Zhuhai-Macao Bridge tunnel, striking architectural concrete structures are currently being built. In the top of the graphic, the western exit can be seen.

The construction team achieved the best SB 4 architectural concrete quality with a clearly structured joint and tie arrangement as well as permanent water impermeability for the walls of the tunnel entrance

For the circumferential wave breakers as well as for the multi-storey operation buildings on the artificial islands, the highest possible architectural concrete quality was a decisive requirement.

Countless timber formers and other cut‑to‑size plywood panels were used for the circular shaped areas.

One operation building during construction from the bird's eye view: Beams and slabs were to be concreted separately

The cut-to-size plywood formlining for the formwork of the large-sized columns was planned and produced in Weissenhorn, Germany.

For the construction team, execution of such high architectural concrete quality was an entirely new experience.
