Impresiones del proceso del proyecto.
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.
The internal formwork moves hydraulically over the launching beam into the reinforcement cages.
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.
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. Pontoons stabilize the tunnel sections during towing operations to the lowering point in the South China Sea.
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.
