Abstract:
An earth anchor, comprising:a thin, elongate base having a longitudinal axis of symmetry, a transversely disposed leading end and a transversely disposed trailing end; an elongate anchor means having a distal end secured to said elongate base, said distal end positioned below the surface of the earth when the earth anchor is inserted into the earth and said elongate anchor means having a proximal end positioned above the surface of the earth when the earth anchor is inserted into the earth; a nozzle attachment means positioned at said leading end of said elongate base; said nozzle attachment means being disposed normal to a plane of said elongate base; said nozzle attachment means adapted to releasably engage a leading end of an elongate jet pipe means; said elongate jet pipe means adapted to, be positioned substantially parallel to said elongate base when said leading end of said elongate jet pipe means is releasably engaged to said nozzle attachment means; means for introducing a liquid fluid under pressure into a trailing end of said elongate jet pipe means; whereby said elongate base is inserted into the earth by first positioning said elongate base in substantially normal relation to the surface of the earth with its leading edge in abutting relation to said surface; whereby liquid fluid under pressure is introduced into said trailing end of said elongate jet pipe means and flows from said leading end of said elongate jet pipe means to form a borehole in the earth; whereby tension is applied to said elongate anchor means while downward pressure is applied to said trailing end of said elongate jet pipe means while said liquid fluid is flowing from said leading end of said elongate jet pipe means until said earth anchor reaches a predetermined depth; whereby said elongate jet pipe means is withdrawn from the earth when said earth anchor reaches said predetermined depth; whereby said proximal end of said elongate anchor means is pulled upon after said elongate jet pipe means is withdrawn; and whereby said earth anchor rotates about said trailing end when said proximal end of said elongate anchor means is pulled upon until said earth anchor deploys into a position where it is substantially perpendicular to said borehole; whereby said earth anchor presents substantial resistance to displacement from said preselected depth when so deployed so that preselected items may be tied to said proximal end of said elongate anchor means to secure said preselected items to the surface of the earth.
