The local HD & Lowes stores only carry 12 inch diameter tubes.
Help!!!
HD Supply Whitecap, Hub Has It
I know I can get one same day here in Southern California between 5 locations. In Phoenix I'm sure at least next day at the latest.They carry them or are they an order item? Mother effers close at 4pm. wTF!!
From the detail why dont you just auger a 24" hole?
Thats what we do. Only time we use sona tubes is if the footing/concrete is above finish surface. Like a light pole standard.I think that’s where I’m heading.

For 24 inch you need to use a bobcat or mini ex with an auger attachment on it
Depending on how many Boulders are underground, you may have a problem using an auger. Usually that size auger is attached to a bobcat or equivalent.
I’m having a hard time finding one that big. 16-18 inch is all I’m finding online.

That's a strange detail drawing.
I don't think sonotube should be used on an in ground pier. The vertical friction bearing component of the concrete to soil interface would be absent, and it would not provide the same weight bearing strength. Besides that, you would have to overexcavate the hole somewhat to put the sonotube in. Then what? How do you backfill it properly?
I'm not a civil engineer or concrete guy, but that's how it looks to me.
