The invention relates to a method for forming a support wall in the ground from a soil mortar which is made in the ground by mixing soil material and a cement suspension, wherein vertically directed support beams comprising a structural steel are set into the soil mortar in the ground prior to curing, and after curing, soil material is removed along an upper support wall section on at least one side of the support wall, while a lower support wall section continues to be surrounded by soil on both sides. According to the invention, it is provided that a thin-walled sheathing element from concrete is attached to at least one support beam, which extends along an upper support beam section, and that the support beam is set into the soil mortar in such a way that the upper support beam section with the sheathing element from concrete extends along the upper support wall section.

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.

The present invention is a tieback installation system, comprising: a mount, wherein the mount is secured to a piece of machinery having mechanical, hydraulic, and electrical connection means; a motor mechanically connected to the mount and hydraulically and electrically connected to the piece of machinery; and a drive shaft connected to the motor, wherein the drive shaft is sized to receive an anchoring member.

Reinforcement assemblies, reinforcement fixtures, methods of constructing a reinforcement assembly, and methods of constructing a reinforcement fixture are described herein. An example embodiment of a reinforcement assembly comprises a plate, a plurality of connectors, and a plurality of elongate members. The plate comprises a plate lengthwise axis, a plate center axis, a plate top surface, a plate bottom surface, and a plate outer surface. Each connector of the plurality of connectors is attached to the plate outer surface and each elongate member of the plurality of elongate members is attached to a connector of the plurality of connectors.

An apparatus for connecting an earthen formation to a concrete facing of a mechanically stabilized earth (MSE) structure, and a method of manufacturing the same. A one-piece, flat, plate-like connector has a stem and a tab, wherein the stem is resistance welded to a soil reinforcing element embedded within the earthen formation. The tab is connected to a facing anchor attached to the concrete facing. The stem of the plate connector has grooves formed in its opposing sides and longitudinal channels to increase the strength of the resistance weld.
