Hi Everyone well i got the hole for the TX472 dug yesterday , but, there was some confusion between me and the backhoe guy somehow... instead of a hole 5x5x6.5 i ended up with a really nice 5.5x7.5x7
Nasty! Had you looked into getting the concrete pumped from the truck to where it was needed? Cost? -=- Alan AB2OS On 10/04/03 02:14 pm dan bookwalter put fingers to keyboard and launched the followi
Dan... you are not alone... earlier this summer I had nearly the identical situation happen here. The hole turned out much bigger, the concrete truck sank in soft clay AND got stuck between two trees
That's what they make concrete pumpers for. I almost never try to get a a fully loaded truck back to a hole. Besides the obvious of ruts and getting stuck, there's the problem that the concrete comes
I went through a similar experience. It took two concrete truck loads to do three tower bases after the backhoe guy got through with them. NEVER let a full size backhoe near a tower base hole! Chuck
Its quite normal for the average Joe, used to seeing 8-wheelers on the tarmac, not to have any idea just how heavy these trucks are ! Watch the wheels of one parked up on a verge one day, and you can
I checked on the cost of a pumper...I was quoted a minimum of $600 here in eastern PA... and that was too much for me. I am SO glad that I then asked the concrete supplier to send someone to inspect
Doesn't anyone use forms any more??? David Robbins K1TTT e-mail: mailto:k1ttt@arrl.net web: http://www.k1ttt.net AR-Cluster node: 145.69MHz or telnet://dxc.k1ttt.net _________________________________
After much reading here on TowerTalk, my conclusions were that forms have to be removed after the pour and then the space has to be backfilled... with compression every foot or so. That would be more
Well look at the bright side.... with all that concrete you can make the tower talled Norman N8NH Hi Everyone well i got the hole for the TX472 dug yesterday , but, there was some confusion between m
Hello, What I did to pour about 7 yards of concrete for my LM470 2 weeks ago was to rent a concrete buggy. My tower pad was 150 ft from the cement truck. It cost about 70 dollars to rent the gas powe
What for? I assume you mean below grade. The concrete is supposed to be poured into 'undisturbed' earth. An exception would be when the walls keep sloughing; then the forms would be necessary but yo
IT WASN'T A MISTAKE. Backhoes are NOT precision tools. In my experience, about 90% of the holes dug end up bigger due to sloughing, rocks, etc. Cheers, Steve K7LXC TOWER TECH - Professional tower ser
to forms remove that is normal up here, due to rock and soil composition its almost impossible to dig a hole of any specified size. and unless you are building late in the summer when its been very
The more I read about this, the more I'm liking my emerging plan to dig a hole with a truck mounted auger rig -- no forms, no backfilling, relatively small diameter surface. We're looking at a 2' dia
OK, maybe my ignorance is showing, but does anyone else think it a bit preposterous for an engineer to recommend digging a 25 foot deep hole for a tower base? If the soil content would allow augering
I would hate to do the rebar for it. A 25' long rebar cage that has to be positioned in the middle of the hole and have clearance to the sides all around. and pouring would be a problem also, free fa

Sure, there are truck mounted augers that can bore a lot deeper than 25'... The cave in issue is mostly for the upper layers of soil. Once you get down very deep, the soil tends to be more like "soft
