ABSTRACT:
Saturated sand or silt is densified at depth by applying a radially propagated lateral translation force within a region of the soil, while water is actively withdrawn from such region toward the point of application of such force. A densification device incorporating the foregoing principle has a mechanism which imparts to the region surrounding the device cyclic lateral displacements which act axi-symmetrically to the longitudinal axis of the device; and, a filtered cavity and pumping mechanism for withdrawing water from the region surrounding the device.
