ABSTRACT:
The present invention discloses a stay anchor and a method for driving it into the soil. The stay anchor includes a pair of cutting members pivoted with each other through a pair of connecting plates and each comprising an arcuately curved resisting plate and a stabilizing plate extended from the inner major surface of the resisting plate at right angles thereto. A driving device is also provided for engagement with the upper end of the stabilizing plate to exert the driving impacts thereto. When driven, the pair of cutting members are driven into the soil along a curved path due to the curved resisting plates and opened or angularly spaced apart from each other with the curved resisting plates bearing against the undisturbed soil so that excellent holding power may be developed.
