Air lifting for cleaning pile works (Air Lift)
(OP)
Dears, Hello
I have piles in a project that I want to clean at the bottom (16 m or 53 ft deep) the water may be as low as a couple feet at the bottom or more. There is a technique called "AIR LIFT" that I came across in many piling resources, which I want to utilize.what I need is what will be the typical diameters for those pipes, how much air pressure is needed , at what ranges (minimum depths) the idea works. and any sketches that might be available online
Regards.

The problem is that I do not know (and I do not think there is ) any such company here, piling is itself quiet new where I live. I came across this page (http://www.plantservices.com/articles/2002/12/) where an empirical equation is given , but it gives me much lower numbers. A concern I have is if the system would work for low levels of water (say I have only 3 ft at the base of the 53 ft deep pile). I think I will start with a 1" pipe for the air and 3" for the water pipe.

I do not think you will have much success with only 3 feet of water in the bottom. You need to be able to fill the pile at least half full of water and keep replenishing it.
Gravel may need a bigger pipe and more air. Construction airlifts often have 6-inch or 8-inch pipes and a lot of air and will actually remove cobbles.
With only a little water at the bottom, you might succeed with a vacuum truck. Don't try to pump the water that far; slurp it like coffee.
If you are only removing water, not dirt, a mop on a rope works.
