A support system and method to support structures in a substrate such as the ground. The system generally comprises a tubular hollow body with a conical head, and a number of smaller hollow tubes positioned inside. Each of the smaller tubes having a bend and an opening adapted to communicate with a corresponding opening in the hollow body head. In use, the assembly is driven into the substrate to the desired depth, and rods are driven down each of the smaller tubes so that they at least partially extend out from the head and into the surrounding substrate. The support system may also include a screw structure at the head to aid in driving the support system into the ground, and guards to protect the smaller tubes from damage during installation.

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.

An anchor installation vehicle that includes a vehicle frame having a top end and bottom end, one or more rotational thrusters, and an anchor system configured to hold an anchor extending from the bottom end of the vehicle frame.

An expanding anchor and/or pile system wherein an outer shell of the pile/anchor is split lengthwise into at least two pieces and can be placed or driven into a hole in the earth in a retracted state and can subsequently be expanded such that the two or more pieces are forced outwardly—away from one another, thus causing them to exert a lateral force against the sides of the hole and thereby resulting in greater axial load carrying capacity in tension or compression of the anchor/pile.

The present invention relates to a method and a system for making prefabricated foundations ready to be driven into the ground, these foundations have the fundamental characteristic of increasing the size of the reacting pressure “bulb” in the ground compared to the currently known fixed foundations, in fact, compared to a traditional foundation fixed in the ground, in which the area of the foundation section is constant, the present invention allows to increase this area by increasing it during the insertion of the foundation itself.

The present invention is directed to a horizontally extendable silt fence. The present invention is also directed to a silt fence system comprising a horizontally extendable silt fence comprising a water permeable geotextile material having an upper edge and a lower edge, and a plurality of posts comprising an upper portion strutted and arranged to be coupled with the upper edge of the water permeable geotextile material, a lower portion structured and arranged to be coupled with the lower edge of the water permeable geotextile material, and an anchor portion structured and arranged to be driven into the ground to anchor the post. Also disclosed is a method of filtering silt from a fluid stream.

The invention relates to an elongate fixation device (1) for use in subsea anchoring, and a method for installation. The device (1) has a triple nested stem arrangement, the innermost stem (2) of which has a cutter (9) disposed at a distal end and a tapered section (8) located adjacent to and proximally behind the cutter (9). An intermediate stem (3) surrounds at least a central portion of the inner stem (2) and has one or more flareable cutting fingers (7) at its distal end. An outer stem (4) surrounds a proximal portion of the intermediate stem (3). The inner (2) and intermediate (3) stems are coupled by a first releasable coupling (17) which when released allows relative axial motion along a first distance. The outer and intermediate stems are coupled by a second releasable coupling (18) which when released allows relative axial motion along a second distance. The intermediate stem 3 is nested within the outer stem (4), in some cases for at least a majority of the outer stem (4). In some examples, the outer stem (4) has a rotationally driveable portion 10 and the inner stem 2 has a tensioning nut (12) for adjusting the relative axial positions of the inner (2) and outer 4 stems. The tensioning nut (12) and the driveable portion (10) are coupleable to a single rotational drive (23). The invention also relates a method for installation and to installation apparatus (21).
