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.

This patent pertains to secondary containment systems. One implementation includes a support assembly that includes an elongate post member and a stabilization plate. In one instance, a stabilization plate is mounted on the elongate post member to reduce movement of the elongate post member when the stabilization plate is embedded in the ground. Another implementation includes a panel splice assembly including reinforcing members that secure overlapping, corrugated panels.

Backflow during installation of a ground anchor is controlled using a preventer, and the preventer is removed during curing of grout and backflow. A cylinder may be inserted at least partially into a structure, and the preventer placed or attached atop the cylinder. A hollow bar may be extended through the preventer and cylinder into one or more layers of materials beyond the cylinder. Grout may be delivered to the layer(s) through the hollow bar, which may cause a viscous backflow to flow into the cylinder and preventer. During application of the grout, the preventer may be used to control a rate of backflow. After application of the grout, the preventer may put into an open position, and a seal assembly forced down the hollow bar, through an interior cavity of the preventer, to a position below the preventer, after which the preventer may be removed while the grout and backflow cure.

A barbed micropile for soil reinforcement at a target location and a method for soil reinforcement at a target location. The barbed micropile includes a conical-head pipe which comprises a hollow rod, a conical head, and a first plurality of T-shaped elements mounted around an outer surface of the hollow rod. The method may include generating a cavity at the target location, filling the cavity with grout, generating a well at the target location by inserting a barbed micropile into the ground at the target location, filling a space between the barbed micropile and the well's wall with grout, and filling an inner chamber of the hollow rod.

A pile is disclosed which includes an elongate member having a longitudinal axis, and an anchoring portion connected to the elongate member. The anchoring portion has a plate and also an arcuate member that is radially spaced from the elongate member. The plate has an arcuate distal edge. The plate is connected to the elongate member at a non-perpendicular angle to the longitudinal axis. The arcuate member is located on the arcuate distal edge of the plate. The plate has a leading portion which includes a lower portion of the arcuate distal edge that extends beyond the arcuate member and engages the earth as the pile is screwed into the ground.

The present invention relates to a foundation reinforcing apparatus using a bracing-type supporting structure and a lateral prestressing device and a foundation reinforcing method using the same, wherein, in the foundation reinforcement used for remodeling construction that requires an extension of a building such as an apartment, the foundation reinforcing apparatus introduces lateral pre-stressing force into a bracing-type supporting structure to introduce a preloading load to a new pile of a new footing by using an upper supporting plate, which is connected to an existing vertical part and an existing slab, as a reaction bed and allows the new pile to share a load applied before and after the extension of the building so that reinforcement efficiency is increased, and thus construction is performed economically.
