Abstract:
1. A ground anchor assembly with a leading section cutting device comprising: a shaft member having a longitudinal axis defining an axis of rotation between a proximate end and a distal end, said proximate end temporarily securable to a driving mechanism; a first and second borehole cutting tip securable to the distal end of said shaft member, said first borehole cutting tip securable to a first side surface of said shaft member having a first notch and said second borehole cutting tip securable to a second side surface of said shaft member having a second notch, said first borehole cutting tip and first notch constructed and arranged to direct said first borehole cutting tip to extend outwardly from the distal end, said second borehole cutting tip and said second notch forming a mirror image to said first borehole cutting tip and said first notch; at least one helically shaped plate secured to said shaft member, said at least one helically shaped plate having a top surface and a bottom surface with an outer perimeter surface, said at least one helically shaped plate having a leading edge positioned approximate to said distal end and a trailing edge spaced apart from said distal end by a predetermined distance; a first plate cutting tip attached to the leading edge of said at least one helically shaped plate, said first plate cutting tip positioned to extend below the bottom surface of said at least one helically shaped plate and parallel to the axis of rotation; a second plate cutting tip attached to the perimeter edge of said at least one helically shaped plate, said second plate cutting tip positioned to extend below the bottom surface of said at least one helically shaped plate and parallel to the axis of rotation; wherein rotation of said shaft permits the first and second borehole cutting tips to bore through rock and said first and second plate cutting tips available to enter the rock after the first and second borehole cutting tips to bore through rock whereby said at least one helically shaped plate ensures that a ground anchor device will be able to auger to a proper depth necessary to support a load of a structure.
