Abstract
A method for altering a characteristic of the ground. The method comprises the steps of preparing a lignocellulosic material, suspending the lignocellulosic material in a slurry to create a lignocellulosic slurry, The method further includes the step of injecting the lignocellulosic slurry below the surface of the ground into a subterranean aperture. The method also comprises the placement of anchoring devices in the ground to alter at least one force experienced by the ground so that the shape of the subterranean aperture into which the solids are transported is altered.
Claims20
A method for altering a characteristic of the ground comprising:
- placing one or more anchoring devices in the ground;
- adjusting the one or more anchoring devices to alter at least one force experienced by a portion of the ground;
- transporting an aqueous fluid under a surface of the ground into an aperture created by the hydraulic pressure of the fluid within the ground, the aperture's shape is constrained by the forces created by the one or more anchoring devices;
- a lignocellulosic material suspended in an aqueous fluid is
- transported from the surface of the ground into the subterranean aperture, and
- the lignocellulosic material is accumulated in a subterranean space defined by the aperture;
- and
- allowing a portion of aqueous fluid to exit the vicinity of the accumulated lignocellulosic material.
A method for altering a characteristic of the ground comprising:
- transporting an aqueous fluid under a surface of the ground to create an aperture by the hydraulic pressure of the aqueous fluid within the ground;
- suspending a lignocellulosic material in the aqueous fluid;
- transporting the lignocellulosic material in the aqueous fluid from the ground surface into the subterranean aperture;
- the aperture is opened by hydraulic pressure;
- the lignocellulosic material is accumulated in the subterranean space created therein;
- removing or releasing aqueous fluid at another location of the aperture,
- pumping a portion of the removed aqueous fluid and the suspended lignocellulosic material back into the aperture or a different aperture;
- effecting removal of a portion of the aqueous fluid from the aperture at a ground location distinct from the location where fluid is added;
- and
- recovering a portion of the liquid that exited the aperture for delivery again to the originating subterranean aperture or a different aperture.
A method for altering a characteristic of the ground comprising:
- transporting an aqueous fluid under a surface of the ground to create an aperture by the hydraulic pressure of the aqueous fluid within the ground;
- suspending a lignocellulosic material in the aqueous fluid;
- transporting from the ground surface into the subterranean aperture at a depth of more than 5 m and less than 100 m below the ground surface and within which aperture the lignocellulosic material is accumulated;
- wherein more than 50% by mass of the lignocellulosic material does not pass a 5 mm square screen opening;
- and
- wherein the lignocellulosic material is more than 50% by mass of the solid delivered to the subterranean space.
