Abstract:
An apparatus for paving a narrow gauge trench in a concrete roadway while being moved along the trench by a vehicle, the apparatus comprising:a roadway surface engaging movable frame having walls extending between opposed ends and adapted to be attached to a vehicle, said ends being spaced apart a distance greater than a predetermined trench width; an auger rotatably disposed in said frame extending between said opposed ends of said frame; a hopper attached to said frame for feeding wet concrete from a source of wet concrete into said frame at one end of said auger; a concrete dispensing aperture formed through a lower one of said walls of said frame adjacent another end of said auger, whereby when said frame is positioned on a roadway with said ends of said frame on opposite sides of the predetermined width trench and said concrete dispensing aperture over the trench, said hopper is provided with wet concrete from the source of wet concrete and feeds the wet concrete to said auger, and said auger is rotated to move the wet concrete from said hopper to exit said frame through said concrete dispensing aperture, movement of said frame along a longitudinal axis of the trench at a predetermined speed fills the trench with the wet concrete; and a strike-off member attached to said frame rearwardly of said concrete dispensing aperture for engaging the roadway surface on either side of the trench and leveling the wet concrete dispensed into the trench, said strike-off member being hingedly attached to said frame for movement between a raised inoperative position and a lowered position engaging the roadway surface.
