Plate-lined soft-ground tunnel incases concrete sewer pipe
Pressed steel liner plates bolted to rib rings l over-bar ine thirteen 16-ft shafts on Cuyahoga Heights, Ohio, sewer tunnel; spaces between plate and pipe are backfilled with concrete which is pumped from surface by pumpcrete machine; shot of high-pressure air into concrete discharge line between pump pulsations helps pack concrete backfill around pipe; illustrations of typical work stages.
