摘要： Systems and methods to provide pressed aggregate-filled cavities for improving ground stiffness and uniformity are disclosed. According to an aspect, a method includes using a mechanism to press into a ground surface in a substantially downward direction to create a concavity. The method also includes substantially or completely filling the concavity with unstabilized or chemically stabilized aggregate, soil, or sand. Further, the method includes using the mechanism to press the aggregate within the concavity to achieve a desired ground stiffness.

摘要： Extensible shells and related methods for constructing a support pier are disclosed. An extensible shell can define an interior for holding granular construction material and define a first opening at a first end for receiving the granular construction material into the interior and a second opening at a second end. The extensible shell can be flexible such that the shell expands when granular construction material is compacted in the interior of the shell. A method may include positioning the extensible shell in the ground and filling at least a portion of the interior of the shell with the granular construction material. The granular construction material may be compacted in the interior of the extensible shell to form a support pier.

摘要： An apparatus and method for ground improvement includes a device having a plurality of tines extending downwardly from a top plate in a manner to achieve displacement of ground material downward and radially outward. The tines may include ridges spaced vertically along an outer surface of the tines. The tines may also be in the form of opposing plates. The device is mechanically driven into the ground to achieve predetermined depths of penetration by the tines/plates. The device is retracted and driven repeatedly to achieve densification. Optionally, voids made by the device can be filled with a flowable media.

摘要： Methods and apparatuses for compacting soil and granular materials are disclosed. In some embodiments, the soil compaction apparatuses include an arrangement of diametric expansion elements that, in their expanded state, form a larger compaction surface. In another embodiment, a compaction chamber can be provided with diametric restriction elements and a flow-through passage in the upper portion of the chamber exterior of a drive shaft. The diametric expansion or restriction elements can be fabricated from, for example, individual chains, cables, or wire rope, or a lattice of vertically and horizontally connected chains, cables, or wire rope. Embodiments of the soil compaction apparatus include, but are not limited to, closed-ended driving shafts, open-ended driving shafts, flow-through passages, no flow-through passages, removable rings for holding the diametric expansion/restriction elements, and any combinations thereof.

摘要： 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.

摘要： A primary earth penetrating mandrel formed of a hollow shell steel plate octagonal in cross-section has an upper end and a blunt lower end joined by an upwardly and outwardly tapered wall. The mandrel is driven downwardly in the earth to simultaneously form a vertical tapered 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 blunt 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 at which time the upper aggregate portions are densified by either the primary mandrel or a secondary mandrel having a substantially larger lower end surface than the lower end surface of the primary mandrel. A second embodiment includes a conduit in the primary mandrel for injecting concrete or grout into aggregate previously deposited in the cavity.
