摘要
A forming tool made to be drawn by tractor-feeder means of any type. The tool comprises two arms mounted to pivot by their front ends on the tractor-feeder. At the back end of the arms is mounted a needle ramp for immersion vibration so as to keep the concrete delivered and distributed by the tractor-feeder in the liquid state before its forming. The forming means comprise an upper element which has a front part in the form of a shield for the regulation of the amount of concrete introduced under the form, and a back part serving as forming upper plate and simultaneously as back reference and support means for levelling the tool, the latter being entirely carried by the formed concrete layer. Side forming plates are also provided.
