ABSTRACT:
The present invention is directed to multi-shaft apparatus and methods for forming soilcrete columns and walls and grids in situ in soil whereby adjacent boreholes are drilled so as to reach bedrock at substantially the same time. Each shaft is equipped with a penetrating auger blade at its lower end. Overlapping auger blades, vertically offset from the penetrating auger blades, are attached to alternate shafts. The columns may overlap or be approximately tangential to each other. Columns may be positioned in a row so as to form a wall, or may be positioned in a grid so as to fixate a region of contaminated soil.
