The present disclosure relates to a soil displacement drill comprising a drill pipe; a widening at one end of the drill pipe that is provided with (1) a screw blade for screwing the drill into the substrate, and (2) an outlet opening for the passage of material that is introduced for forming the foundation pile; and a flap that is movable between a first position for allowing unhindered screwing of the drill into the substrate and a second position for preventing the material from entering a screw groove. The screw groove is formed in the substrate by the screw blade during unscrewing of the drill from the substrate. The disclosure further relates to a method for forming a smooth foundation pile using such a drill.

A modular foundation support system includes modular foundation support components including shafts provided with integrally formed coupler features on their respective distal ends. The coupler features are configured with a non-uniform wall thickness defining a plurality of sections of respectively different diameter to matingly couple the shafts to one another in a torque transmitting relationship. The coupler features may be integrally formed and fabricated on the distal end of each respective shaft.

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.

Disclosed is a pylon anchoring system in the form of an extruded strip that may be wrapped around, and affixed to, a pylon or post such that the pylon anchoring system is positioned beneath a sand line when the pylon or post is installed and set. Advantageously, when the post or pylon is installed such that the pylon anchoring strip is positioned beneath sand (or some other ground surface), a plurality of anchor elements on the system generate a counteracting force to any external force that might cause the pylon to shift from a set position.
