Abstract
An apparatus and method for improving the structure of saturated masses of granular materials. The apparatus comprises an axially elongated probe having a generally cylindrical side wall and upper and lower ends, the lower end being adapted to penetrate the mass, the side wall having a screen portion to restrict the passage of particles therethrough, and to pass water therethrough into a space within the probe. There is a vibrating member located within the probe and generally adjacent the screen portion to generate a vibrating force within a region of the mass. At least one impeller blade is located within the probe generally adjacent the vibrating member to generate a low pressure zone to draw the water from said region into the space. A discharge conduit communicates with the space associated with the screen portion and the conduit extends upwardly to the upper end of the probe. An air-lift pump is located at the upper end of the probe in communication with the discharge conduit to expel water from the space. A motor located within the probe and generally adjacent the vibrating member powers the vibrating member and the at least one impeller blade.
