b. Whenever practical, use mechanical or hand earth augers to dig the holes for anchors. Vary
the depths of setting for the anchors to permit the eye of the anchor rod to project not less than 6 inches
(15.24 cm) nor more than 1 foot (.30 cm) above the ground. (See Figure 2-17.)

Installation of cone anchors.
a. Determine the desired location for the ground end of the guy, and bore or dig a hole for the
anchor (Figure 2-18). Dig this hole to the required depth and in line with the proposed guy. Make the
circumference of the hole slightly larger than the circumference of the guy anchor.
b. Attach the correct size anchor rod to the anchor and lower it into the hole. Position the
anchor in the hole to align the guy rod with the line of the proposed guy. Turn the anchor rod, if
necessary, to position the eye properly.
c. Place crushed stone around the anchor for a depth of 2 feet (.61 m). Place the stone in small
lots and tamp each lot thoroughly. Backfill the rest of the anchor hole with earth. Heap and pack soil
around the top of the guy rod.
5.
Installation of expanding earth anchors.
a. Determine the location for the guy anchor hole and dig the hole (Figure 2-19). Make the
circumference of the hole slightly larger than the circumference of the anchor in the closed position.
Attach the anchor rod to the anchor. Be sure the nut on the anchor rod is screwed tightly against the
anchor and the anchor is free to expand.
