PRESSURIZED-SLURRY SHIELDS BORE SUBMARINE TUNNELS

To construct two 865 m submarine railroad tunnels under Tokyo Bay, the Nishimatsu Construction Company used shields filled in the front cutter chambers with pressurized slurry. In operation, all pumps are synchronized for constant slurry pressure 284 psi slurry containing soil is pumped through exhaust pipe to treatment centers.
