Abstract: A concrete deposition device includes at least a concrete delivery unit and a leveling element in a single unit. The device can be moved across an edge of a concrete mass under deposition to simultaneously place and level plastic concrete. The device may also include a screed trailing the leveling element to provide additional compacting and control of the top surface of the concrete mass. In a preferred embodiment a carrier translates the deposition device along a predetermined path to provide for improved ease and accuracy in the formation of the concrete mass.

Abstract: A vibratory concrete screed including alternating turnbuckles and tubular housings, mated together for adjusting tension and screeding surface camber. The turnbuckles and tubular housings include interior space therethrough which houses an elongate rotatable shaft for providing vibration. The elongate shaft includes eccentric weights rotating within bearings within the turnbuckles and driven by drive shafts driven in turn by a motor located at one end of the screed. The screed includes male and female joiner pieces having mating bearing surfaces for securing abutting screed sections. The invention also includes a laser alignment system for adjusting camber.
