Wash Boring* Method -sorry-
What I don't understand about this method is where the soil sample is going.


"A casing is driven with a drop hammer. A hollow drill rod with chopping bit is inserted inside the casing. Soil is loosened and removed from the borehole using water or a drilling mud jetted under pressure." Is The soil removed mixed with the jetted water?? I mean completely mixed, with no form like the shelby pipe, but a liquid with soil particles? Or How exactly, step by step, is the sample extracted? D: Please help, I really dont understand.

It took me twelve seconds to locate this description by searching for "wash boring method":

That should clear things up.

The soil/particles comes out with the drilling mud/water after being loosened by the chopping bit. The drilling mud is used to prevent the sides of the bore from caving in so it would not be needed if the bore was cased. The link refers to collecting samples from the bore which would involve replacing the chopping bit with a sampling bit.
