A grade management system configured to control a depth of a dig includes a vehicle including an arm assembly coupled to an implement, the implement configured to dig into a surface, and an implement position sensor coupled to the arm assembly, the implement position sensor configured to detect a position of the implement relative to the vehicle, wherein in response to digging into the surface with the implement, detecting the position of the implement relative to the vehicle and determining whether any portion of the implement reaches a targeted depth into the surface.

A ratcheting auger bracing device having a support frame with spaced-apart elongated side bars and first and second end bars connecting the side bars, and a pair of pivotable braces each having a proximal hinge end secured pivotally to and around the end bars of the support frame, a distal end bar, and a pair of opposed arms connecting the distal end bar to the proximal hinge end. The opposed arms are angled downwardly, acing the shaft of the auger section, to provide improved operation of the ratcheting auger bracing device in muddy operation conditions. An elevating frame provides an elevating base and legs that elevate the support frame and the hinged pair of pivotable braces at a distance above the ground level, and positions the hinged ends of the pivotable braces a distance above the ground level that avoids or prevents mud that may pool around the well hole.

The disclosed systems for laying underground fiber optic cable may include a drive body, at least one rotational motor, a forward auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a first rotational direction, and a rear auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a second, opposite rotational direction. Various other systems, methods, and devices are also disclosed.

The present invention is a digging auger. The digging auger comprises a shaft with a proximal end and a distal end. The digging auger also comprises a screw extending from the proximal end to the distal end of the shaft. The digging auger further comprises a paddle attachment adapted to be removably attached at the proximal end of the shaft. The paddle attachment comprises two pieces of rubber strips arranged on opposing sides of the shaft and extending generally radially outwards therefrom.

The disclosed systems for laying underground fiber optic cable may include a drive body, at least one rotational motor, a forward auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a first rotational direction, and a rear auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a second, opposite rotational direction. Various other systems, methods, and devices are also disclosed.

An apparatus and method for drilling an underground borehole is presented, wherein pressurized air may be used to discharge out of the borehole cuttings created by a cutter head. A casing may be secured to the cutter head such that the cutter head and casing may be rotatable together as a unit. The casing may have larger and smaller diameter sections. An auger may be disposed adjacent the front of the casing.

A boring apparatus for coupling to a drill rod and drilling a borehole includes a boring tool head configured to couple to the drill rod and receive drilling fluid. The boring tool head has an exterior surface with a hole and defines an internal cavity. The hole is configured to receive ground spoils such that the ground spoils are conveyed into the internal cavity, and the drilling fluid dispenses into the cavity such that the drilling fluid mixes with the ground spoils to form a drilling slurry. A housing is coupled to the boring tool head and has a chamber in fluid communication with the cavity. A pump in the chamber is configured to pump the drilling slurry out of the cavity and the chamber.

The present invention relates to a hollow boring auger for use for poles, including a first and second mounting part moveably connected, one to the other, to substantially encircle the pole. A first and second auger part are also included, correspondingly attachable to the first and second mounting part, to substantially encircle the pole, A rotation apparatus associated with the mounting parts and the auger parts is included such that in use the auger parts can be rotated about the pole to bore a hollow trench about the pole. The invention also relates to a method of use.

An auger attachment system for an extendable boom having a first stage, and a second stage, the auger attachment system having a fixed mounting configured to couple to an auger, the fixed mounting being coupled to the second stage of the extendable boom, an extendable mounting, configured to couple to the auger, the extendable mounting being coupled to the first stage of the extendable boom, and a linear actuator configured to extend and retract the extendable mounting to transfer the auger from the extendable mounting to the fixed mounting.

A mixing system for producing a drilling fluid for ground drilling includes a feed for a powdered medium and a mixing chamber with a feed for a fluid medium. A space is provided between the feed for the powdered medium and the mixing chamber, having sliding elements therein, which sliding elements can seal off the space at one end.
