Re: Deep Pit Excavation


Thank you all for your responses. The consensus seems to be that this hole should be shored. What if the sides were at 3:1 (18 degrees), do you still need shoring? How about if one side was at 3:1 to allow equipment to "drive-in", could this be dug with scrapers?

I am trying to figure out the most economical way to dig this hole (excavation part only). The site is in a rural area and the spoils will be stockpiled nearby just outside the hole.

Re: Deep Pit Excavation


Jeez. I think you need to call someone who is local and does this for a living. A hole this size? Most economical isn't really the word you are wanting.

Safe and low liability would be my first thoughts.

What have the local professionals you must have called told you. That it will be expensive? That it isn't as easy as getting a bigger shovel?

This would be like me asking how to build a 10 story highrise and then asking on here how to most economically do it.

Lots of steps you are missing.

Re: Deep Pit Excavation


Home Depot has one of these. Pretty cheap, too.


Bang it out in a few hours, none of that safety S$#! needed.

Yeah, isn't that a Ryobi product?

Re: Deep Pit Excavation


7-D, 4-1: Some large draglines don't have 'Prime' movers, but use High voltage transformers near the work area.....

The OPer would have to find out if the correct electrical supply was available for an electric powered solution....

To below: YODO! get a pro on the shoring....

Oh My Gosh. You don't say.







That's a picture of Big Muskie. It was the largest walking dragline in the world, until it was dismantled in the late '90's.

My post was meant as sarcastic humor, with a bit of hyperbole thrown in, in order to make a point, that the OP might be in a bit over his head.


I was not seriously suggesting that HD rents a 27 million pound excavator that no longer exists. But now that I've seen your sig line, I'll be sure to speak very slowly, and use only small words with lots of those funny little yellow faces.

Re: Deep Pit Excavation


The "Big Muski" ran at night as much as possible to get cheaper electricity....

It was larger in EVERY dimension then The OPers Hole would be....

At 140 yards a bucket full, 30 scoops = one hole, more or less....



If you under claim intelligence, you disappoint far fewer people, IMHO.

An extraordinary bright Idiot, or a sub- par Genius?
