The apparatus includes an aggregate materials hopper; a hollow mandrel adapted to be driven into the ground; a plurality of rubber bearing isolators disposed between the mandrel and the hopper for reducing transmission of vibratory energy between the mandrel and the hopper, and a rubber seal encircling and moulded to the outer circumference of the mandrel for preventing aggregate leakage from the hopper; flow control means comprising a stone gate or hinged tip convertible between an open position and a closed position for controlling aggregate flow, one or more collars encircling the mandrel disposed along the length of the mandrel, each collar having an outer circumference greater than the mandrel circumference; a vibratory hammer attached to a vehicle for inserting and removing the mandrel into the ground; and a monitoring and control system in the cab of the vehicle. | 07-11-2013 |
| 20140056651 | METHOD OF PROVIDING A SUPPORT COLUMN - A primary earth penetrating mandrel formed of a hollow shell steel plate has an upper end and an open lower end joined by an upwardly and outwardly tapered wall. The mandrel is driven downwardly in the earth to simultaneously form a vertical cavity while compacting the sidewall of the cavity to provide structural integrity. The mandrel is then moved upwardly from the bottom of the cavity and aggregate is deposited in the bottom of the cavity following which the mandrel is lowered so that its lower end engages the deposited aggregate and densifies the aggregate by vertical vibratory action and static force with these steps being repeated until the pier top is near the surface of the earth. A second embodiment includes a conduit in the primary mandrel for injecting concrete or grout into aggregate previously deposited in the cavity. | 02-27-2014 |
| 20140314497 | Polymer grouting method for constructing gravel pile - A polymer grouting method for constructing gravel pile for reinforcing the soft and special soil foundation includes steps of: (1) pile-position-pore-forming; (2) installing a grouting pipe; (3) putting graded stones; (4) polymer lifting grouting; and (5) pile-forming. By pile-position-pore-forming, putting graded stones, polymer lifting grouting in the reinforcement site and other steps, the injected two-component expansive polymer material expands rapidly after a chemical reaction, and then is solidified with the graded stones for filling in the pile hole from below to above, the blast hole wall rock-soil is expansive compacted and fully integrating with the surrounding rock-soil, thus forming the polymer gravel pile. The present invention can rapidly reinforce the soft and special soil foundation, thereby providing an advanced, highly efficient, safe and practical method for reinforcing the soft and special soil foundation. It has great economic and social benefits and broad development prospects. | 10-23-2014 |
| 20160017562 | RAPID PIER - A method and apparatus for rapidly constructing a structural pier comprising the steps of placing into a soil under a structure to be supported a casing having an inner diameter and an outer diameter, positioning an injection tube into the inner diameter of the casing, and injecting an expansive material into the casing. Optional perforations in the casing allow some of the expansive material to be ejected from the casing into the surrounding soil to create fingers or branches for the purpose of adding friction to the structural pier. | 01-21-2016 |

| 405241000 | Dispensing auger | 3 |
| 20120087740 | AUGER GROUTED DISPLACEMENT PILE - Disclosed in this specification is a method and apparatus for placing an auger grouted displacement pile or helical pile in soil. The pile has an elongated shaft with at least one lateral compaction protrusion which establishes a regular bore diameter in the supporting medium. The pile also has a helical blade configured to move the pile into the supporting medium. The bottom of the shaft includes means for forming irregularities in the bore diameter after compaction by the lateral compaction protrusion. The bore is then filled with grout while leaving the pile in the soil. | 04-12-2012 |
| 20150345094 | APPARATUS AND METHODS FOR THE PLACEMENT OF PIPE PILING - Apparatus and methods for the installation of pipe pilings into the ground for use as structural building foundations, geothermal piles, or both, are disclosed. In addition to specialized fittings for pipe pile assemblies, the inventions include specialized drive mechanisms used in conjunction with rotary or vibratory motors. Methods of installing pipe pilings are further improved with the disclosure of methods of adding grout or similar materials during or after installation of the piles. | 12-03-2015 |
| 20160060838 | SEISMIC RESTRAINT HELICAL PILE SYSTEMS AND METHOD AND APPARATUS FOR FORMING SAME - A reinforced helical pile system suitable for use in seismically active areas incorporates steel fibers in the grout and a fiber reinforced polymer sleeve (casing). A low-friction driving assembly and low-friction sleeve couplings enable the sleeve to be drawn into the soil substantially without rotation, reducing power consumption and preserving the integrity of the casing. | 03-03-2016 |

| 20140178131 | Efficiency of Geothermal Ground Improvement System - Provided herein are apparatus, systems and methods for use in ground construction. New ground improvement methods have been developed using pervious concrete piles, the piles having material properties of the pervious concrete, as well as positive response to different vertical loads. The methods produce piles that are superior to aggregate piles in most aspects, and that can be utilized in construction in a wider variety of soils and applications, including in geothermal heat exchange (energy pile) systems. | 06-26-2014 |
