APPARATUS FOR AUTOMATICALLY EXTRUDING AND FORMING A FINISHED CONCRETE CHANNEL
An apparatus for automatically extruding and forming a finished concrete channel in a drainage ditch. The apparatus includes a frame having support rails for positioning the apparatus over a drainage ditch. A concrete-receiving hopper is attached to the frame for delivering received concrete into the ditch to be shaped into a channel form. A mold having a projection to define a concrete surface of the channel is positioned beneath a top portion of the frame and configured to be received in a hollow mating portion of a laterally-reciprocating piston to shape the received concrete. A lever driver drives the reciprocating piston through a mechanically-linked motor. A vibrator cooperates with the concrete-receiving hopper to urge received concrete into the ditch to be shaped by the mold.
