Mobile reinforced concrete pipe machine

Abstract

A mobile reinforced pipe machine for producing and laying concrete pipe on site in a ditch or the like. The machine comprises a frame structure capable of supporting the machine for movement along a ditch; hydraulically positionable outrigger wheels carried by the frame for machine guidance along the ditch; a pair of rotating nested sleeves with compactor vibrators therebetween which receive solidifiable cementitious material, such as concrete, vibrate the entering mixture to assure uniformity of mix; longitudinal and circumferential reinforcing wire fed between the sleeves for embedding within the solidifiable cementitious material for reinforcing the solidified pipe leaving the machine; plates or slip forms are attached to the frame adjacent the sleeves for receiving and supporting partially solidified pipe as it exits the machine as the machine moves forward; motor and transmission to transport the machine along the ditch and rotate the sleeves. Earth compactors are provided to force backfill under the newly-formed pipe for support.
