Abstract:
An apparatus intended for incorporation as a module within ground improvement pokers such as those already patented (U.S. Pat. No. 6,554,543 and U.S. Pat. No. 8,419,316) in order to enhance the field performance of those hydrodynamic compactors by either improving their ground penetration capability, and/or, maintaining or recovering the permeability of their outer seepage filtration element; involving a method which can be activated remotely at the operator's discretion, while those parent devices are at depth within the earth. This apparatus and method may have application in water well installations and reviving flow in oil wells.

Claim (Index 7):
A method whereby the apparatus defined in  claim 5  can be utilized to improve either the geotechnical characteristics of saturated ground, or the physical characteristics of mine tailings, whichever subject material said apparatus may be traversing, while accomplishing such improvement without compromising the normal functionality of said parent device, and achieving these benefits while continuing to traverse said subject material, by reversing the direction of rotation of said axially aligned drive shaft, thereby activating said module with the following results:\n where the upper half of said spiral coupling is forced to rotate while the lower half of said spiral coupling is prevented from rotation; and, \n where such relative motion results in said dead weight being alternatively raised and then subsequently abruptly dropped with each full rotation of said axially aligned drive shaft; and, \n where raising said dead weight draws water into the space vacated by said dead weight; and, \n where the abrupt falling of said dead weight expels water from the space previously occupied by said dead weight through said water conduits incorporated within said nose cone, and such pressurized water thereafter being ejected through said well screen openings thereby ridding said well screen of any particles of said subject material clogging openings in said well screen; and, \n where the restoration of maximum perviousness of said well screen openings both optimizes the performance of said parent device, and reduces the frictional resistance between said parent device and said material through which it is moving; and, \n where said dead weight produces a vertical impact load on the bottom of said nose cone cavity with each fall, thereby promoting penetration of said parent device through said material.
