Boring green-hydro, cryo vertical drilling

Abstract

A vertical water jet cutter method of boring holes in the ground and other solid substrate managing the difficulties of removing the center stone by freezing it until brittle, and cracking it from the base yet to be cut or fragmenting it and removing the material. This process is repeated until the desired or prescribed depth of the boring is reached. Means to handle unexpected dissembly of equipment in the boring is handled with tie-lines to each component placed to dangle the part in an orientation that will allow removal of the part without disturbing the walls of the boring. Means to handle invading ground water includes cryogenically freezing the region of the boring from where the water is flowing, melting the ice in the center of the boring, applying mortar to displace the melted ice and settle in the crevasses of the rock, curing it, and then water jet cutting the boring through the mortar and on into the rock below. With a deep area of ground water penetration, this process must be repeated. This type of water jet cutter boring has many applications from water well drilling, insitu fuel extraction, assaying minerals and more. Comparing this method with the standard drill methods, the equipment is low-profile, cost effective, and no waste. Water and grit are recycled, powdered stone, fragments, and whole center stones can be sold for use elsewhere. This method will not ruin the landscaping or forest floor beauty long term. The energy expended is directed at the cutting zone in the boring.

1 . A method of vertical drilling into the earth using water jet cutting technology comprising the steps of:
 a. Auger drilling the soil and subsoil granular material with larger diameter than intended boring;   b. Inserting a sleeve with inner diameter greater than the intended boring extending from the ground surface to the first encountered rock bed;   c. Beginning water jet cutter boring by inserting the superstructure including the water cutter heads mounted on radial arms, high pressure lines, evacuation tubes, Venturi pump and containers and cutting as deeply as possible the circumference of the boring;   d. Moving the water cutter head so as to cut the circumference of the boring;   e. Removing the cutting apparatus and inserting the Liquid Nitrogen sieve and slow flow applicator dispersing the Liquid Nitrogen in pulses so the Liquid Nitrogen rains down in droplets evaporating as it reaches the bottom of the boring freezing to brittleness the rock material there;   f. Either cracking off the center stone at the base or fragmenting it for removal to the surface using a shape charge, a pistol bullet, or vibrations;   g. Raising the broken free center stone or rock fragments to the surface clearing the boring for another cycle as here described.   h. Repeat this sequence until the desired depth of the boring is reached.   
   
   
       2 . The method according to  claim 1 , wherein the water jet cutter heads are positioned such that the cut runs parallel with the vertical axis of the boring and retains the diameter of the boring by tilting the cutting heads inward so the cone of cutting outer line cuts the boring wall parallel to vertical and at the determined wall diameter in cross section. 
   
   
       3 . The method according to  claim 1  wherein the tilting of one or more of the plurality of water jet cutters from left to right, and upon reaching a stop changes the turning motion from right to left, and encountering another stop reverses the direction of the turning again from left to right enables the water cutting assembly to move cutting the full circumference of the extending wall of the boring being cut. 
   
   
       4 . The method according to  claim 1 , wherein the water from the water jet cutter, grit used to hasten the cutting and resulting powdered stone is vacuumed from the lowest encirclement of the cutting to enable further cutting. 
   
   
       5 . The method according to  claim 1 , further comprising the step of cryogenically freezing until brittle the stone center of the drilling using Liquid Nitrogen which eases the task of breaking off the center stone or fragmenting it for removal from the boring. 
   
   
       6 . The method according to  claim 1 , further comprising the step of capturing and raising the stone broken free or gathering the fragments and transporting them to the surface. 
   
   
       7 . The method according to  claim 1 , wherein an angled spatula enables the placement of the shaped charge wet with glue on the lower section of the center stone, which, upon detonation, snaps off the stone at the base. 
   
   
       8 . The method according to  claim 7 , wherein the whole center stone is harnassed and drawn to the surface with three hoisting lines to keep it vertical. 
   
   
       9 . The method according to  claim 1 , further comprising the step of removing the frozen, brittle center stone by fragmenting it by pistol shot or vibrations caused by two dissonant sound sources. 
   
   
       10 . The method according to  claim 9 , wherein a sequence of nets on a loop gathers the fragments of the center stone, and, having a hoist line on each net, takes the full inner net with rock fragments to the surface while the remaining nets on the loop are filled with rock fragments and, again, removing the filled center net until the fragments are removed or the net loop needs refilling. 
   
   
       11 . The method according to  claim 1 , wherein the sequence starts again with the water jet cutter assembly lowered into the boring and cutting another segment. 
   
   
       12 . A method of recycling both the water used in the water jet cutter and the grit, and preserving the powdered rock to sell conserving these materials. 
   
   
       13 . A method of overcoming ground water invasion of the boring using the steps:
 a. Freeze with Liquid Nitrogen water and rock at the bottom of the boring;   b. Applying soft mortar such that the warming as it cures melts the ice in the boring and rock crevasses near the boring wall filling the space well into the rock wall with mortar;   c. Allowing the mortar to cure sufficiently;   d. Inserting the water jet cutter apparatus and continue boring through the mortar and down through the rock; and   e. If groundwater is again flowing in the boring, repeat this process.   
   
   
       14 . The method according to  claim 13  wherein the encountering of ground water will not prevent the continuation of drilling since ground water invasion is controlled giving the water jet cutting process the required air, not water, filling the space between the water jet cutter and the material being cut. 
   
   
       15 . A method of insuring equipment can be removed from the boring of having a line secured to each part such that, if dissembled in the boring, the equipment parts, one at a time or together in group assembly, can be pulled from the boring without locking on the walls on the way up and out. 
   
   
       16 . A method of vertical boring or drilling that can be applied in a range of circumstances. 
   
   
       17 . A method of vertical boring or drilling using water jet cutting that gives little disturbance to the surface in the vicinity of the boring during and after the task. 
   
   
       18 . A method of vertical boring or drilling that directs all energy at the point where material in the boring is being cut and removes material once filling the hole. 
   
   
       19 . A method of melting ice in the bottom of the boring using the exothermic heat of Calcium reacting with water to produce Hydrogen and Calcium hydroxide to clear the way for mortar flow into the crevasses in the rock which holds back the ground water invasion of the hole being bored.
