A frangibility device for creating a preferred breakage plane or weakness within cured columns such as rigid inclusions (RIs) and/or vibratory concrete columns (VCCs) comprises a cutting disc, an elongate strut attached to the center of the disc, and a detachable handle for turning. The disc comprises a thin geometric plate slit from center to periphery, so that a slicing wing can be bent downward at a shallow angle from the slit. The slicing wing advances the cutting disc through the cementious material of the uncured column. When the disc reaches the desired depth, the handle is removed and both disc and strut are left in place during curing.

An alignment and installation jig for a screw anchor driving machine. The alignment and installation jig includes a laser target that can be moved from an alignment position to a driving position. The jig may also include one or more automated crimping assemblies to form permanent connections between overlapping foundation components while the machine is correctly oriented.

Various examples are provided related to mobile segmental rail foundation systems, and their assembly, deployment and use. In one example, among others, a mobile rail foundation system includes a segmental rail foundation including a plurality of anchor assemblies and at least one sectional spacer rail assembly configured to detachably attach adjacent anchor assemblies to form the segmental rail foundation. The anchor assemblies can be coupled to soil anchor assemblies and/or hold down assemblies to secure the segmental rail foundation in position. The soil anchor assemblies can include helical pile soil anchor assemblies and the hold down assemblies can include forked hold down plate or brackets secured by anchor bolts.

In a machine for driving screw anchors and other foundation components, a desired embedment depth is calculated based on a minimum required embedment depth, work point height and length of available upper leg sections. Once calculated, the machine automatically drives the screw anchor to the depth so that one of the available upper leg lengths will fit between the driven screw anchor and apex truss hardware. If uplift is detected during driving, the machine will add additional embedment depth. In-situ validation of driven screw anchors may be performed after the embedment depth is reached.

The present invention relates to a building system and a method of making and assembling the building system. In particular, the present invention relates to a footing for a building structure, the footing comprises a plurality of precast concrete layers, each precast concrete layer comprising reinforcement bars and a plurality of apertures. The footing further comprises a base structure comprising a base plate and a plurality of alignment bars protruding from the base plate. The footing is configured such that when the plurality of precast concrete layers are positioned on top of one another, the plurality of alignment bars of the base structure extend through the respective apertures of each precast concrete layer. Furthermore, the present invention relates to a building structure having one or more building modules.

A grouting module may include a lower surface configured for connection to a screw pile component, an upper surface configured for connection to an upper hollow pile shaft, a body disposed between the upper surface and the lower surface, and an axial bore through the upper surface and at least a portion of the body. The body may include a flange configured to create an annular space around the upper adapter and one or more flow injection conduits configured for injecting grout received from the upper hollow pile shaft through the axial bore extension into the annular space while the pile is advanced downward into a substrate. Once the final pile tip elevation is reached, the pile extensions above the grouting module are counter-rotated slightly to realign the ports in the grouting module from side to bottom discharge and allow post-grouting of the lead pile extension.

A rotary auger support stand for holding objects such as decoys above the ground. The auger support stand includes at least one rod of longitudinal support member or shaft. The rotary auger anchor comprises a helical coil for screwing that end of the stake into the ground. handle means such as an S-shaped handle provides a crank handle for rotatably screwing the anchor into the ground or at least two opposing legs extend perpendicular from and between the shaft and auger forming a base. The distal end of opposing legs are bent upward perpendicular from the ground or bent upward and inwardly at an acute angle toward the shaft forming handles for rotating the auger into the ground. The transverse legs extending from the elongated support pole provides a base bearing against the ground for increased lateral support. The top distal end of the shaft includes means for supporting an object.

The present disclosure provides embodiments of anchors and screw anchor kits. The anchors are used to pull anchor rods used for anchoring loads to the ground. The anchors may include a wrench hub, a power point and a helical plate. The screw anchor kits may include an anchor and an anchor rod. The screw anchor kits may also include a drive wrench used to drive the anchor and anchor rod into the ground, and an eyelet that can be attached to an end of the anchor rod extending above the ground.

In general, one aspect disclosed features an anchoring system for anchoring an at least partially floorless mobile livestock enclosure to the ground. The anchoring system comprising: a securing flange configured to mechanically couple the anchoring system to the enclosure; an anchor; and a drive configured to place the anchor into contact with the ground, and to retract the anchor from contact with the ground.

A grouting module may include a lower surface configured for connection to a screw pile component, an upper surface configured for connection to an upper hollow pile shaft, a body disposed between the upper surface and the lower surface, and an axial bore through the upper surface and at least a portion of the body. The body may include a flange configured to create an annular space around the upper adapter and one or more flow injection conduits configured for injecting grout received from the upper hollow pile shaft through the axial bore extension into the annular space while the pile is advanced downward into a substrate. Once the final pile tip elevation is reached, the pile extensions above the grouting module are counter-rotated slightly to realign the ports in the grouting module from side to bottom discharge and allow post-grouting of the lead pile extension.
