1. A construction machine for use in the controlled distribution of formable concrete along an elongated transversely limited site having a base surface of a predetermined configuration and a predetermined lateral dimension, said machine comprising:

  • a main frame for movement longitudinally along the base surface, said main frame including a front section and an elongated trailing section extending substantially rearwardly therefrom, said sections overlying the base surface on which the formable concrete is to be distributed;

    propelling means mounted beneath said main frame and adapted to be supportingly engaged by the base surface as said frame moves thereacross;

    a first hopper means mounted on said frame front section and overlying such base surface to receive a load of formable concrete from a source independent of and positioned forwardly of said machine on the base surface on which said concrete is to be distributed;

    an elongated mule mounted on said frame trailing section and extending laterally therefrom and being spaced a substantial distance rearwardly of said first hopper means and rearwardly of said propelling means, said mule overlying such base surface and including a second hopper means having an undersurface conforming substantially to the predetermined configuration of the base surface in supporting engagement with said propelling means;

    conveying means carried on said main frame and extending from said first hopper means to said second hopper means in a direction generally longitudinally of said construction machine for controlled rearward transfer of formable concrete from said first hopper means to said second hopper means;

    vibrating means operatively mounted on said second hopper means; and

    control means mounted on said main frame and operatively connected to said propelling means for controlling relative movement and steering of said machine along the base surface, whereby concrete delivered to such machine from a source on such base surface forward of said machine is placed on said base surface by said mule at the rear of said machine.
