Bell bottom pier auger 1

[PostFrameSE]

Can anybody give me some resources as to where I can look into a bell bottom pier auger? I'm looking for small scale holes here where the shaft may be 10" or something and the bell at the bottom would be 20". My depth of hole will only need to be 4' to 6' deep. Perhaps I'm showing my ignorance by throwing out that 10" and 20" number, but this thought is very new to me and I am not finding much information by Googling.

Thanks.

Look up a piling company in your area - to see if they have the equipment and can help you. Usually in the yellow pages under contractor piling or contractor foundations

BigH that reminds me of a very old joke. The story goes that if you look up "Boring" in the London Yellow pages you are told to look under "Civil Engineering".

Yeah - we used to use a "hand over open mouth" (yawn) for boring and if followed by index finger-thumb circle to mimic "borehole". But the geotechs I knew when I first started out were anything but . . .

For such a short hole the savings in shaft concrete does not justify the complexity of a belled pile. If you need the uplift, there is a plastic funnel that can be topped with a cardboard column form and placed in an excavated pit and backfilled, then filled with concrete. I think it is called Bigfoot.

Thanks all,

Pslem, I think I'd have to agree with you on that. I still wish that I knew how those things worked and if people rig up their own or if there are products out in the marketplace that can do this.

Try Erickson Equipment. They have belling tools.
