20110170959 | TRIPLE-PRONGED GROUND IMPROVEMENT TOOL AND DEPLOYMENT ARRAY - A method is given which it is believed will lead to better ground treatment results for both engineering and environmental purposes. The novel advancement over conventional equipment and machines (called pokers) suggested herein is that rather than simply deploying a single ground improvement poker at a time, a triangular array of three pokers, deployed from a single mobile carrier, be activated in the ground together and simultaneously at a particular location. Considerable synergetic advantages are anticipated not only by the mutual interaction of multiple machines in close proximity, but also by the ability to excite the three individual pokers at different frequencies and/or phase relationships with respect to their partners. In the special case of the equipment previously disclosed in U.S. Pat. No. 6,554,543 further enhancements in ground improvements are anticipated by assiduously selecting the pressures at which water or fluids are pumped into or out of the three individual prongs of the composite array of cooperating hydrodynamically assisted vibrators. A deployment pattern devised for this particular triple-pronged tool is given which will allow full and efficient contiguous coverage of any area requiring treatment. | 07-14-2011 |
