Hello-
This week we had a construction / concrete contractor tearing out the old
asphault driveway and replacing it with concrete.The asphault was underlayed
with fairly thick rock and he was using a fair sized trackhoe to excavate it
out.
I had a damaged 25-G base { about 15' away from driveway, was hit by a
worker here last year} , this tower was one of the corners for a 580 foot loop
{ HOHP } using 4 of 55 foot 25-G towers. The base 10' section was set 5' into
the ground with close to a yard of concrete and some rebar. He assured me that
he could remove the tower base with the trackhoe. He bit at the concrete base
and pulled/pushed against it, rocking it back and forth a couple of times.Then
we tied onto the 4-1/2' tower stub with a good sized chain attached to trackhoe
bucket.We went around all 3 legs and under crossbraces, etc. The chain ended up
actually pulling apart the entire tower base piece, actually shearing off the
leg sections, but it did allow the concrete mass to move upward about 1' out of
the hole. We had to tie around the concrete and then pulled the mass out in one
piece.
I do have to say that this is the first time that I ever have re-used a
tower base hole!! Boy, it saved me some work for sure.Just a tidbit of info in
case someone else may be faced with a similiar situation as this. CUL, Byron
WA5THJ.
