Description

This disclosure relates generally to a system and method for soil saturation and digging. Further, this disclosure claims the benefit of provisional application No. 61/360,349, filed Jun. 30, 2010.

BACKGROUND

In one embodiment, Mr. Zizak disclosed a post hole borer (U.S. Pat. No. 3,638,741). Said post hole borer can comprise a hydraulic boring tool comprising, a cylindrical member, and inner cylindrical member connected thereto at the extremities of the cylindrical members and spaced therefrom to define an annular area therebetween, a pair of handles connected to the first named cylindrical member, one of said handles having a passage therethrough connected to the annular area between the cylindrical members, valve means associated with the passage and adapted to open and close the same, a plurality of apertures positioned around the connection between the cylindrical members at the extremity opposite the handle members, said handle member having the passage therethrough being adapted to be connected to a source of water under pressure, and said inner cylindrical member being open at both extremities. Although a suitable tool for hydraulic digging, said post hole borer is limited for a variety of other uses. Namely, said post hole borer, as disclosed, is designed for digging post holes and would not be suitable for everyday garden digging, or for loosing soil around an existing object for removal of said object. Further, said post hole borer does not provide a shield for protection its user from diverted liquid splashing back at said user during operation. Further, due to a plurality of cylindrical members in said post hole digger, said extremity opposite the handle members is likely to have trouble penetrating a surface without the use of a tool, such as a toothed or serrated outer cylinder defining a saw-type surface to engage the earth and loosen the same as said post hole borer tool is used. In one embodiment, said post hole borer can “erode the soil and the water will carry the soil along with the water up through the interior of the inner cylinder to be discharged out of the aperture in the top flange of the cylindrical structure”; accordingly, said post hole borer is not well suited for saturating a subsurface without leaving said subsurface otherwise intact without removing said subsurface.

Several embodiments require a vehicle to carry a large and complex digging apparatus. Such embodiments comprise a pressurized liquid or gas for breaking apart earth, a vacuum for lifting excess earth and/or liquids from the point of digging. Such embodiments are limited, however, as they require a vehicle for operation. They are not suited individual users in common household cases due to their size and complexity. Due to the need of said vehicle and said vacuum, such embodiments are complex and generally only suited for larger jobs.

In another embodiment, a water pressure post-hole digger (tool) is disclosed by Mr. Sikes (U.S. Pat. No. 6,196,337 B1). In one embodiment of Sikes, said tool includes an elongate conduit member having an upper end for receiving a flow of water under pressure and a lower end; and an enlarged mandrel member mounted to said lower end of said conduit member, said mandrel member comprising: an elongate body portion having upper and lower ends and a generally circular cross section; a generally axial bore formed in said body portion for passage of said flow of water there through; a nozzle opening formed at said lower end of said body portion for discharge of said flow of water therefrom; and a generally conical taper on said lower end of said body portion for accelerating and directing said flow of water into a generally annular passage around said body portion; so that said flow of water which is discharged from said nozzle opening excavates a bottom of a post-hole bore and flows upwardly through annular passage around said body so as to remove soil material along upwardly-extending sides of said bore. As such, Sikes discloses a hydraulic digging tool. Nonetheless, Sikes leaves much to be desired; for example, said embodiment provides a means of excavating a subsurface rather than saturating and loosening said subsurface without removing the same. Further, said embodiment does not provide a shield to prevent excavated subsurface material from splashing back at users of said embodiment. Likewise, said embodiment does not provide a means of minimizing disbursed subsurface material. Further, Sikes requires a conical shaped end on his disclosure. Finally, said embodiment has a large and problematic mandrel which will cause problems when inserting said embodiment into a surface and into said subsurface.

Accordingly, a system and method for soil saturation and digging would be advantageous.
