Abstract
An elongated tubular ground anchor having a leading driving end with an internal impact receiving abutment and a tapered out-turned trailing end has an external cable swingably secured thereto about midway between said ends but rearwardly of the center of mass of the anchor, is guided and driven lengthwise into the ground to a desired depth by a ram entering the trailing end and impacting the abutment with the cable extending above ground from the hole in the ground formed by the anchor and driving ram. The cable is pulled or tensioned causing the trailing end of the anchor to plow into the ground forming a fulcrum to rotate or tilt the anchor from its upright driving position to an inclined position transversely of the hole and with the leading end remaining lower than the trailing end. The driving ram may be hollow and a concrete slurry pumped through the ram as it is retracted from the anchor and hole to fill the hole with the cable surrounded by the slurry. A plug may then be pressed into the hole to compress the concrete slurry causing it to flow into crevices and pores of the ground surrounding the hole and concrete may then be poured into the hole above the plug while the cable is held under tension. After the concrete sets, a tensioned cable reinforced column of concrete fills the hole and cooperates with the anchor to provide a firmly secured ground anchored cable. The cable anchor may be further strengthened by swaging an entrance hole of larger diameter than the hole formed by driving the anchor in the ground but only extending to a depth substantially less than the depth to which the anchor is driven. This large diameter entrance hole is thereby surrounded by compacted earth due to the swaging operation and may be lined with a tube to keep the hole in an open condition during the driving of the anchor. The liner is withdrawn and the entrance hole is also filled with concrete which is pressed by the plug thus forming a concrete column interlocked with the ground and embedding the anchor and cable.
