Disclosed are embodiments of a method for manufacturing concreate panels for a mechanically stabilized earth (MSE) retaining wall that employ geosynthetic strips that attach to the MSE retaining wall and extend into the backfill soil. One embodiment can be generally summarized as follows: (a) providing a mold for the concrete panel; (b) providing in the mold: (1) a plastic pipe; (2) a metal rod situated in the pipe; (3) a removable block-out insert that creates a geosynthetic strip cavity within the panel body around the pipe for enabling a geosynthetic strip to be looped around the pipe; (c) introducing concrete into the mold; (d) permitting the concrete to substantially solidity within the mold; and (e) after the concrete has substantially solidified, separating the panel from the mold and removing the block-out insert to expose the cavity and the pipe extending through the cavity.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

An apparatus, system and method of connecting an earthen formation to a facing of a mechanically stabilized earth (MSE) structure in which a connector includes a single piece of wire that defines an opening for coupling the connector to an anchor and a pair parallel legs for mechanically connecting the to a soil reinforcing element.

A retaining wall installation process for earth and water retaining wall, first step starting from preparing precast reinforced concrete heavy duty retaining wall (1) on the ground, inserted horizontal rebars (12) at each fin (7) passed to the holes (8), connected mechanical couplers (14) only one end of horizontal rebars. Attached shuttle-platform (16) to precast reinforced concrete heavy duty retaining wail (1). Then lift up to installed the wall at construction site, put down the vertical rebars (15) connected to the lower vertical rebars by using mechanical couplers (14), tie vertical rebars to horizontal rebars, then closed the vertical cavities (24) by using panel closer (28) and poured fresh concrete (29). After final setting time, removed shuttle-platform down to the ground.

The present invention is directed to a retaining wall system including a retaining wall having with at least one retaining wall rebar extending along a vertical direction, the at least one retaining wall rebar includes an end formed into a first retaining wall rebar hook, at least one deadman spaced from the retaining wall, each deadman including a concrete base extending along the vertical direction, the concrete base including rebar extending past the concrete base and having an end formed into a deadman rebar hook, at least a first hole at a top portion of the retaining wall and extending into the retaining wall to expose the retaining wall rebar hook, and a first cable attached to the retaining wall rebar hook and to the deadman rebar hook to support the retaining wall.

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 tieback alignment and access device has a hollow core and vertically aligned angled anchor subassemblies that provide attachment points for tieback anchors that pass laterally through the hollow core. The hollow core is configured to allow a cutting tool (e.g., a drill bit) to be inserted therein longitudinally and used to cut the tieback anchors at any time. When cast into a contiguous temporary support-of-excavation wall, the angled anchor subassemblies are set back from an outwardly facing surface of the wall resulting in a smooth surface.

A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus.

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.
