CONSTRUCTION METHOD OF FABRICATED TUNNEL ON THE WATER-BED

摘要

The method constructs the concrete tunnel on the bed of the river or the sea by using a buoyancy force. It makes possible constructing an underwater tunnel irrespective of the depth of the river or the sea. The method comprises the steps of : installing a water chamber(8) for adjusting a buoyancy force in order to make prefabricated concrete structures(2,2') have an appropriate weight in the water; pushing the concrete structures to a destination by a pushing machine(7) while connecting the concrete structures(2,2').
