Hi, I am trying to get an idea of the equipment needed and timeline to excavate a 20x80 by 60 feet deep pit. I am assuming that due to the small footprint excavators should be used (rather than scrapers). Excavators will create an access road to the bottom and dump trucks will take the soil away. The pit is in hard soil with side slopes at 1:1 grade (45*). What is the most efficient way to excavate this pit? How many excavators and trucks should be used and how long would it take? Thanks
You are going to have to bench yourself down to get to that depth . How did you come up with 1:1 slope . Around here any thing over 20’ has to be engineered. As far as equipment I would go with a 100,000-110,000 pound machine ,can be moved without major disassembly. One machine should be good due small work area. Type of trucks depends on how steep of a road you are going . Time line depends on number variables you run into
This seems like a end of quarter test question...
Did I pass?
Somethings not right here... 60ft deep pit with 1to1 slope and 20 feet wide... how the he** you come up with that?
Try to keep up Gramps. This - BTW how ya' been up in the frozen north - ya'll thawed out yet?
Well CM, still hitting some snow in the peat pile but thats normal. Whatever the weather is here, its bettern that crap you get there!!!!
A dragline with a skilled operator in it.
Yesterday was partly cloudy and mid 70's - didn't even break a sweat.
There should be a test for people to be a member of this site with questions like that.
