Method for construction of tunnels by prefabricated concrete tunnel sections employed in crossing of rivers, involves fixing guide rails with axle supported rolling elements e.g. roller or ball in tunnel shoring for loading tunnel section

摘要

The method involves fixing guide rails with axle supported rolling elements e.g. rollers or balls in tunnel shoring for loading tunnel sections to reduce the power requirement during the assembly. The tunnel sections are guided and rolled exactly in linear manner in the tunnel shoring.
