Abstract
An adaptation of apparatus disclosed in U.S. Pat. No. 5,135,058 to provide foundations or perimeter walls is effected with the drilling of circular holes within a range of four to sixteen feet overlapping to provide continuous area coverage in the case of foundations with a minimum of overlap and to provide a minimum wall thickness in the order of hole radius in the case of containment walls.
Claims1
Method for constructing in-situ a solid substantial area foundation characterized by successively sequentially drilling single overlapping equal diameter circular foundation holes within a range of four to sixteen feet in diameter successively filled with solidifying material in a pattern characterized by parallel rows of overlapping holes having centers equally spaced approximately 0.866 times drill diameter in an "X" direction, approximately 0.75 times drill diameter in a "Y" direction, and with alternate rows having centers medianly offset from the center of adjacent rows to thereby provide coverage of said substantial area with a mathematically exact minimum number of individual single drill holes having no interstitial spaces.
