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.

The invention relates to a ground anchor with a mounting (1) for a parasol or the like, having a sleeve (8) which is pushed over the mounting (1) and on which stabilizers (9, 10, 11) are mounted that can be folded out in a radial or preferably tangential manner. A ground screw (4) is connected to the mounting (1) on the ground side and opposite the object to be supported, for example the parasol. A driver, such as a projection section, a shoulder, or a nut (12) which can be screwed onto the mounting for example, drives the sleeve (8) during the screw-in process and expands the stabilizers (9, 10, 11) against the ground. The mounting (1) can be angled relative to the ground screw (4) by 90 and thus forms a lever for rotating the ground screw (4). The stabilizers (9, 10, 11) can be pivoted onwards in a tangential manner selectively clockwise as well as counterclockwise to a limited degree as a result of stops (14, 15).

Fixed-tilt solar arrays constructed from screw anchors. A row of truss foundation is installed, with each foundation consisting of a pair of adjacent angled truss legs. A truss cap or adapter joins the legs and provides a support structure to support a rail that in turn supports purlins extending between adjacent, spaced apart truss foundations. Solar panels are attached directly to the purlins using clamps or other conventional mounting systems.

A method of installing one or more anchors in an underwater substrate in a body of water including installing an anchor into the underwater substrate by rotating an anchor installation vehicle about a central axis Y to drive the anchor coupled to the anchor installation vehicle into the underwater substrate. The anchor installation vehicle includes a vehicle frame having a top end and bottom end, a plurality of arms extending outward from the vehicle frame, one or more rotational thrusters disposed at distal ends of the respective arms, and an anchor system that holds the anchor extending from the bottom end of the vehicle frame with the anchor aligned with a central axis Y.

Embodiments of the present disclosure relate to a system for reinforcing compressible soil strata. The system comprises at least one helical rigid-inclusion comprising a elongate body, a top member secured to one end of the elongate body, and at least one lower helically-formed member secured to the end of the elongate body opposite to the top member, and a load transfer platform configured to transfer at least a portion of a load from an overlying surface to the helical rigid-inclusion. Embodiments of the present disclosure also relate to methods of installing the system for reinforcing compressible soil.

A ladder anchoring system utilizing a ground anchoring device and a series of strap assemblies to secure the ladder in position and hold the ladder tightly against both the ground surface and the associated structure to prevent tipping or falling. Further, the ladder anchor system of the present disclosure is quickly and easily installed and/or adjusted to allow for ease of manufacturing, assembly, and/or use thereof.

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 to assembly a truss foundation. One crimping assembly device may effect crimp joints between a foundation component held by the jig and overlapping upper ends of a pair of adjacent foundation legs. Second crimping assemblies may telescope down each leg to effect respective crimp joints between the lower end of the leg and the upper end of a driven foundation component.

A pair of truss legs forming an A-frame-shaped truss foundation system, wherein each truss leg is formed from a hollow lower screw anchor having threading around its lower end connected to an upper leg, wherein both the screw anchor and the upper leg have corrosion protection layers formed on their inner and outer surfaces thereof, but wherein only the screw anchor also has a second corrosion protection layer formed over the first protection layer on its outer surface only.

Automated systems and methods for drilling while driving foundation components are provided. In some cases, based on detected conditions, it may be desirable for an automated controller to change the bore diameter of a drill bit during a drilling and driving operation. The need for this may be determined based on monitoring the output of one or more sensors related to one or more corresponding performance metrics of the drilling and driving operation.

A soil nail or micropile comprises a first steel bar having a first end, a second end and a non-threaded exterior surface, a second steel bar having a first end, a second end, and an exterior surface which is threaded at the second end, and a transition coupler joining the second end of the first steel bar to the first end of the second steel bar, whereby when installed in-ground, the first steel bar is located in the ground and the second threaded end of the second steel bar protrudes from a surface of the ground, such as for accepting a bearing plate and threaded nut.
