<p>An earth anchor (1) use for slope stabilization, anchorage or similar works comprises a body (10), a guider (30) detachably connected to the lower end of said body (10) and a plurality of wings (40, 40a) pivotally hinged and secured to the peripheral of said body (10). The plurality of pivotally hinged wings (40, 40a) extends outwardly from the body (10), when the earth anchor (1) is progressively withdrawn from its settled position in the passageway, providing a large projected area to form a wider frustum cone thus enabling a higher anchorage force. A desired anchorage force can be achieved with a lower depth of soil penetration with the earth anchor (1). The design of the earth anchor (1) enables more than one unit of said earth anchor (1) to be interlocked together to increase in number of extended wings (40, 40a) in order to provide for a more positive and solid frustum cone.</p> |
