  • Patent number: 7883295
    Abstract: A method and apparatus are provided for forming an in situ subterranean soil cement structure wherein a soil processing tool incorporates a novel cyclonic mixing region. The cyclonic mixing region is formed by deflecting a jetstream which initially moves away from a hollow Kelly and, after being deflected, the jetstream is redirected into a direction flowing towards the hollow Kelly. A contoured flight is provided having an exterior contoured surface extending upwardly from a central section of the contoured flight and bends through an angle greater than 110° in order to deflect a jetstream which is directed outwardly from the hollow Kelly back towards the hollow Kelly. By preventing any of the high pressure jetstreams from impacting the side wall of the hole, higher jetstream velocities and pressures may be utilized. Two or more jetstreams may also be utilized to direct their jetstreams around a central horizontal axis to provide the cyclonic mixing region.

  • Patent number: 7338232
    Abstract: A screw pile is equipped with internal grout pipes extending downwardly through the bore of the tubular pile shaft. The grout pipes connect with side-opening ports in the shaft side wall, to form conduits through which fluid grout may be injected into the surrounding ground. The grout is injected at high pressure as the pile is rotatively driven into a sub-surface target formation in which the pile is to be landed. In this way, the grout is distributed along a vertical interval of formation. It has been shown that this technique is characterized by increased load capacities of the implanted pile, relative to piles implanted without grouting or with grouting but only at landed depth.

The enlarged base area provides greater load bearing capacity.

The apparatus comprises a beam for making insertions into and extractions out of the ground to form a series of voids therein. The beam includes a hollow interior portion which receives a supply of granular material. The beam also has a plurality of outwardly projecting spurs on the outer faces thereof for scarfing the sidewalls of the void as the beam is extracted. The apparatus also includes a disposable shoe which is removably attached to the open bottom portion of the beam to prevent earthen material from entering the hollow interior portion of the beam as the beam is inserted into the ground. An actuating mechanism detaches the shoe from the open bottom portion of the beam after the beam has been inserted into the ground so that granular material is released into the void as the beam is extracted therefrom.

  • Patent number: 6238142
    Abstract: An apparatus for erecting a foundation element in a ground surface including a drilling device, a pumping device, a pressure transducer and a control unit. The drilling device includes a hollow core tube and an auger bit adapted to drill a hole in the ground surface while the pumping device is adapted to pump a solidifying suspension material under pressure through the hollow core tube and into the hole in the ground surface. In addition, the pressure transducer is mounted on the core tube and is adapted to provide a pressure signal indicative of a pressure of the solidifying suspension material in the core tube while the control unit is adapted to control the pressure of the solidifying suspension material.

  • Patent number: 6183166
    Abstract: A method is provided for centrifugally forming a subterranean, cylindrically shaped soil-cement casing in material located in a subterranean earth situs. A soil processing tool is advanced and rotated into the subterranean situs and as the tool advances a high velocity cement slurry is introduced through said tool to hydraulically divide the pieces of soil into particles and to mix the cement slurry with the particles to form a soil-cement slurry. As the soil processing tool is then withdrawn from the situs, the tool is rotated at a speed to exert a centrifugal force by the tool on the soil-cement slurry in excess of two G's, causing the solids of the soil-cement slurry to migrate away from the center of the hole to form a first cylindrical region at the edge of the hole and a second cylindrical region at the center of the hole. The first region has more of the dense solids and the second internal region has a greater proportion of free water and less of the dense solids.

  • Patent number: 6120214
    Abstract: A process for constructing a jet grouted subterranean column provided with reinforcement. A hole is drilled in the ground to the desired depth using a drill bit carried in a hollow drill rod to which a drill casing is detachably coupled. As the drilling proceeds, grout is applied through the drill rod and is injected sidewardly at high pressure to cut into and mix with the bore wall. The casing is detached from the drill rod and lowered to the bottom of the bore, with the grout filling the annular space between the casing and enlarged bore wall. After the drill rod has been withdrawn from the casing, the casing may be left in place and filled with grout such that the casing provides reinforcement for the resulting grout column. Additional reinforcing material may be inserted through the casing. In an alternative process carried out in accordance with the invention, a bore is drilled with a special drill rod and a sacrificial drill bit.

  • Patent number: 6116819
    Abstract: There is disclosed a method of continuous flight auger piling and a continuous flight auger rig (1), wherein an auger (2) is applied to the ground so as to undergo a first, penetration phase and a second, withdrawal phase, and wherein the rotational speed of and/or the rate of penetration of and/or the torque applied to the auger (2) during the first, penetration phase are determined and controlled as a function of the ground conditions and the auger geometry by means of an electronic computer (8) so as to tend to keep the auger flights loaded (11) with soil originating from the region of the tip of the auger (2).

  • Patent number: 6079906
    Abstract: A method for making foundation piles in soil with a drilling device having an auger, the auger including two concentric tubes, an outer tube occupying an upper part of the auger and an inner tuber projecting partially as a prolongation of the upper part and occupying a lower part of the auger, the inner tuber having a first screw and the outer having one of a second screw and a plurality of blades, both of said tubes being displaceable with respect to each other, the method including the steps rotating the inner tube in a first direction, simultaneously rotating the outer tube in an opposite direction of the first tube and advancing the auger through said soil whereby the soil is compacted against a wall of a formed hole by the combined action of the first screw and the one of the second screw and plurality of blades of the inner and outer tubes.

  • Patent number: 6033152
    Abstract: An improved lateral soil displacement and compaction auger (24) is provided including a central shaft (34) equipped with a central cementious material pipe (42), helical flighting sections (36,38) and lower rollers (64A-64E) positioned between lower flight sections. The rollers (64A-64E) are strategically located so that their outer peripheries cooperatively define an expanding spiral from the lower end of the auger (24) towards the central section (50) thereof. The rollers (64A-64E) are primarily responsible for lateral soil displacement and compaction during rotation of the auger (24) and do so with reduced frictional buildup. The preferred auger (24) also includes a lower cap (40) which is retained during auger rotation by teeth (90,92); during filling operations, the cap (40) is shifted downwardly to allow ejection of cementious material from the pipe (42) while retaining the cap (40).

  • Patent number: 5927905
    Abstract: A method for and inserting a ground anchor into the ground, comprising the step of screwing an elongated anchor body into the ground by means of an extension tube that is to be connected to the proximal end of the anchor body. The distal end of a tension line is connected to the anchor body above the screw blade turns. A pipe sleeve is slid onto the extension tube, while guiding the tension line via an eyelet at the pipe sleeve adjacent to the distal end of the pipe sleeve, from the anchor body along the pipe sleeve. The anchor body is then screwed downwardly by turning the extension tube and the pipe sleeve jointly to a predetermined depth. Finally, the pipe sleeve together with the line extending there along are rotated around the stationary anchor body/extension tube assembly.
