An aggregate pier compacting system for forming a compacted aggregate pier (AP) at a target location includes a mandrel, a tamper device, and a finishing tamper device. The mandrel includes a casing for housing a drilling shaft (DS). An external vibratory hammer (EVH) repeatedly impacts a hammer element (HE) extending from the DS. The DS transfers the impact to a bore head to form a cavity at the target location. The DS is removed and the casing is filled with aggregate. The tamper device includes a compacting shaft. The EVH impacts a second HE extending from the compacting shaft and transfers the impact to a compaction head to form the compacted AP. The finishing tamper device includes a shaft. The EVH impacts a third HE extending from the shaft and transfers the impact to a finishing head compacting a top layer of the AP to form a finished AP.

The present invention relates to the field of bioinspired geotechnics to provide an alternative to conventional vertical and inclined skirted footings and their method of installation. The invention provides tree root inspired substructure with improved load carrying capacity and a method of installation. Tree root inspired substructure herein defines a square or rectangular or circular or strip footing with closely spaced vertical/inclined micropiles. This hybrid substructure takes advantage of depth effect, width effect, arching effects, compaction and relative ease in installation on level and sloping grounds as compared to conventional skirt/bucket foundation. The micropiles attached to the traditional footing are spaced such that the trapped soil in-between behaves as a plug and major load shearing/transfer takes place at the level of tip of micropiles. Some load distribution also takes place along the micropiles and underneath the footing. The uplift, moment, lateral and vertical load carrying capacity gets enhanced due to the increase in the depth of foundation without much efforts on excavation. The proposed foundation can be cast-in-situ or precast or hybrid. Micropiles of the footing could be installed by either driving or boring. Micropile material can be solid/hollow steel or reinforced/unreinforced concrete, while the footing can be made up of steel plate/frame or reinforced/prestressed concrete. Appropriate selection of a bioinspired skirted footing saves a lot of material and construction time as compared to conventional skirted footing, leading to cost savings.

An assembly for a truss foundation embedment and installation machine. The machine mast has a rotary driver, target assembly, and a truss component holder. After a pair of foundation components are embedded, the truss component holder is moved to an orientation location that aligns the rotational axis of a specific tracker bearing with respect to a work point of the truss foundation. A truss cap is placed on the truss component holder and held in place while upper leg sections are sleeved over the truss cap and down onto the embedded foundation components. A hydraulic crimper is used to crimp the portions of each upper leg section that overlap with the truss cap and the embedded foundation components to unify the truss foundation.

A first support assembly for supporting a building structure includes: a pile adapted to be anchored into a ground surface; a first bracket extending from the pile in a first lateral direction; a second bracket extending from the pile in a second lateral direction substantially perpendicular to the first lateral direction; a top surface for receiving a beam; a first attachment member for connecting the first bracket to a first beam supported by a second support assembly in the first lateral direction; and a second attachment member for connecting the second bracket to a second beam supported by a third support assembly in the second lateral direction. A method is also described.

Methods and Systems provide for a Rapid Deployment Robotic Self-Installing and Self-Leveling Payload Structure (hereinafter, RDR-PC) anchors a payload structure to site with no prior site preparation. The RDR-PC is ideal for remote, and/or difficult installations-whether on/off world-where deployment/development speed is critical and prior access to site is impractical, limited, or impossible. Leave-no-trace removal of the same system is achieved by reverse process.
