ABSTRACT:
The invention provides exemplary earth anchors and methods for their use. In one exemplary embodiment an earth anchor comprises and elongate hub having a trailing end and a leading end. At least one blade is attached to the hub, with the plate having a discontinuous circular periphery. The blade is configured such that a continuous circle drawn around the periphery of the blade defines an area. The blade has an area that is less than about 70% of the area of the circle, and the ratio of a path at shear resistance for the blade to the perimeter of this circle is greater than about 90%. Tubular extensions are attached to the hub and poured above the hub to facilitate injection of a low-strength, impermeable non-cementitious chemical grout in order to seal potential paths for water created by installation of the anchor and thereby reducing the risk of increase rate of soil heave in expensive soils.
