Amsterdam-Rhine Canal Water Transport Tunnel
HEIGHT: 2.85 m
WIDTH: 8.89 m
DEPTH AT BOTTOM OF STRUCTURE: 10 m approx.
TOTAL IMMERSED LENGTH: 132 m
ENVIRONMENTAL CONDITIONS:
Constructed across an active canal.
FABRICATION METHOD:
Match cast segments. A special measuring post was
used to measure the length of the next segment to be
cast. The segments were joined with epoxy resin and
temporarily prestressed. Finally 32, 55 mm cables and 6
BBRV cables were used for final post-tensioning. Element
was assembled in a vacant canal lock.
