A budding element for coupling with other budding elements to erect a retaining wall. Exemplary building elements have receiving spaces for receiving increased weight of fill material to provide increased stability. Optionally, each building element can have an enlarged face profile that provides efficiency in the shipping and assembly process. Optionally, each building element can define alignment voids that receive portions of alignment posts for ensuring vertical alignment between adjacent building elements or portions of building elements.

A method for constructing a retaining wall using an adjustable single stage panel system has the steps of placing a wall panel adjacent a fill location, then placing a facing wedge adjacent the wall panel, and installing fabric sheet. Next, adding a layer of fill material in the fill location abutting against the facing wedge, and compacting the layer of fill material so that it is compacted against the facing wedge. Then, placing an elongate non-extensible panel anchor on top of the layer of fill material, and attaching the elongate non-extensible panel anchor to the wall panel. At a next step, the facing wedge is moved up to a next course above the layer of fill material, and fabric sheet is installed. An additional layer of fill material is added and compacted with enough force to mobilize the fill. Finally, the method includes the steps of removing the facing wedge, and adjusting the elongate non-extensible panel anchor so that it is plum with the wall panel.

A reinforcement element for a diaphragm wall including a reinforcement cage, the reinforcement element further including a seal-carrier provided with a mounting part for receiving at least one seal, which is elongated, the seal-carrier being fixed to the first end part of the reinforcement cage and extending along the longitudinal direction of said reinforcement cage, the seal-carrier defining a housing for receiving the seal, at least a first part of which is surrounded by a sacrificial material.

The foundation system includes a below ground rigid raft foundation to bear a load for an above ground structure, and granular cushions and piles formed below the raft foundation. The granular cushions are configured for uniform load distribution of the raft foundation and the piles are configured to bear a load of the above ground structure and the raft foundation. The foundation system further includes stone columns encapsulated with a non-woven geofabric and configured to stabilize the raft foundation. The raft foundation is disposed adjacent and above the stone columns, the granular cushions are present between neighboring stone columns, and the granular cushions are present between the stone columns and the piles. The stone columns have a cementing agent for stabilization.

Provided is a removable ground anchor body using a rotation wherein when a pc strand or a deformed steel bar is rotated, a screw bar is interlock-rotated to raise an operation member and sequentially raise a body and a wedge from the pc strand or the deformed steel bar thereby to release the connection state.

A pier assembly for supporting a structure has a vertically oriented central axis and includes a plurality of horizontally spaced apart elongate members disposed in the ground and arranged about the central axis. Each elongate members directly contacts the ground. Each elongate member has a length-to-width ratio greater than 10.0.

Disclosed is a multiple friction joint pile connection construction system to construct: shallow and deep foundations for structures, tie beam construction between footings, passive piles to prevent slope failures beam on elastic foundation, pile cap and tie beam in the construction of pile groups, load transfer platforms isolated (not connected) from the upper structure, retaining structure when constructed with vertical and horizontal orientation, vertical and horizontal drain when perforated blocks are used, landing pier, quay wall and platform construction for coastal and harbor structures, by anchoring to the upper section of the existing bored piles, by anchoring to the upper sections of the columns of the upper structure, in railroad tie manufacture, in transportation structures and in all kinds of similar geotechnical applications.

A hexagonal wire netting (7), a process for manufacturing such a wire netting and a device for manufacturing a hexagonal wire netting (7), the device comprising an assembly of tubes (5) for leading the wires (I) of which every other is twisted into a spiral shape, a spindle (6) assembly and a drum (8) receiving the wire netting (7), the drum (8) being provided with detent elements (21). Between each tube (5) leading the spirally twisted wire (I) and the cooperating spindle (6) a straightening guide (IO, IO′) is located having an inlet opening (13, 15) cooperating with the tube (5) and an outlet opening (12, 20) cooperating with the spindle (6). The detent elements (21 are arranged on the drum (8) in such a way that the produced wire netting (7) has meshes in which the proportion of the width (A) to the length (B) is less than 0.75.

What is provided is a precast hollow block, a precast wall system incorporating the precast hollow block, and forms for manufacturing a hollow block and a coping cap. Accordingly, the precast hollow block and its incorporation into a precast wall system provide solutions to current “level up” block coping techniques, wall flood protection, wall force protection, and the like. Instead of having mismatched or missing face textures on sloped portions of the wall, the precast wall system allows for easier installation of face-textured blocks directly at the top of the wall. As a result, the precast wall system may readily account for slope transitions of a wall, conform to specific Department of Transportation project requirements, accommodate existing wall construction specifications, and be easily customizable for a variety of applications.

Disclosed is a device for containing granular elements, comprising a metal mesh panel having metal wires welded together, the panel comprising at least one curvature of a first orientation and at least one curvature of a second orientation, the first orientation being characterized by a first axis and the second orientation being characterized by a second axis, the first axis and the second axis being non-collinear.
