New pneumatic drilling machine for strengthening foundations
Abstract This article describes the design of a new pneumatic drilling machine with a sectional expander and gives its mechanical characterics. The technology of the deep compaction of soil in the vertical plane is examined. Relations and nomograms are presented to determine the distance between drill holes and drilling speed in relation to the diameter and depth of the holes and the sequence in which they are expanded. The dependence of the duration of soil compaction on the time spent performing the main and auxiliary operations is also determined.
