It seems to me that it would be easier to drill round holes with a tractor
powered post hole digger for the guy wire anchor points than try and dig
them by hand. If I use the same amount of concrete as spec'd by Rohn for
their rectangular anchor, wouldn't I be OK? For anchor "4b" that would be
.67 yards.
Let's see, 3.14(1)(1)=3.14 sq ft circle and 9cu ft (.67 cu yd) = 6 cubic
feet; then 6/3.14 = 2 feet .... drill a 24" hole 4 feet deep, gravel on
the bottom, 2 ft of concrete and dirt should make it about equal. Am I close?
By the way has anyone ever calculated "D" on the Rohn "Standard Concrete
Anchors" drawing C620643. I can't find it anywhere on the print.
Thanks in advance, Bruce
