Disclosed is a metallic cage (to create inverted cantilevered and counterfort forces) for supporting a retaining wall of hollow-cored blocks, having (a) first vertical (stem, post) insertable into such cores, a base member extending into the retained soil and a diagonal strut member securely connecting the top of first stem with the distal end of the base member embedded in the retained soil, where the base member has a platform on which to locate a suitable weight.

A method for manufacturing modular retaining wall blocks in natural stone, wherein the blocks are trapezoidal blocks having top and bottom surfaces with channels that receive offset connectors in multiple orientations for building upright, offset, and curved walls. Stone from a quarry is cut or split to form substantially rectangular elongate blocks having top and bottom surfaces, opposed side faces, and opposed ends. A series of channels running parallel to the side faces is cut in each of the surfaces, the top channels lying across from the bottom channels but offset therefrom. The elongate blocks are then cut between opposing pairs of channels to form trapezoidal blocks having front and rear faces.

Landscaping walls, systems and methods of manufacturing and installation of such walls include in aspects a fiberglass based wall having a decorative front side and a back side having at least one conduit where the conduit receives a cable or fastener extending outward from both ends of the conduit to connect to a stake to be inserted into ground adjacent the wall. The conduit in one aspect is a PVC tube mounted vertically against the wall and in aspects is embedded within the wall. The conduit allows for self-adjustment of the cable while also providing solid anchoring of the wall to prevent movement. The wall and system is lightweight, good looking and easy to install.

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.

A segmental wall block, soil reinforcing system, and method related thereto, wherein the wall block may be used for constructing retaining walls. In one embodiment, the segmental wall block may include: a front face; a rear face; a slot disposed along the rear face; a troughed top face; a bottom face; a first and second open core extending from the top face to the bottom face; a first side having a tongue; and an opposing second side having a groove, wherein the tongue is shaped to interlock with the groove. A soil system may include: a wall block component including a first configuration of interlocked segmented wall blocks as described, and a stabilizing component. A method of reinforcing soil may include the steps of: installing a leveling pad of concrete or gravel; and providing a soil stabilizing system.

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.

A load-retention panel having an anchor rod on a load-bearing side thereof forming a horizontal slot therebetween. A securing rod having a diameter greater than or equal to a width of the slot and seated against the load-retention panel and the anchor rod on a first side of the slot. A first section of a flexible sheet extends between the anchor rod and the securing rod and wraps about the anchor rod and the securing rod on opposite sides thereof. The distal end of the flexible sheet extends away from the load-retention panel into and within a landfilling material. The flexible sheet may further wrap about a combination of the anchor rod, the securing rod, and the first section of the flexible sheet with its proximal and distal ends extending through the slot from the first side thereof, and out of the slot from an, opposite second side.

A form system for an in-ground swimming pool may include inner and outer form panels to be coupled in side-by-side relation. Support members may be for coupling the outer form panels in spaced relation from the inner form panels to define a wall space therebetween. Each of the support members may include a base member to be carried by respective inner and outer form panels over the wall space, an arm extending from the base member for coupling to the respective outer form panel, and a wall support member for coupling to the respective inner form panel. The wall support member may include a wall support lip extending from a wall support body for engaging the respective inner form panel so that the respective inner form panel is suspended from the wall support lip.

Provided are a strip-type reinforcing material and a reinforcing material assembly having the same. The strip-type reinforcing material includes: strip bases extending in one direction and made of a flexible material; and resistance means protruding from respective upper and lower parts of the strip bases. Multiple resistance means are provided along the strip bases. The resistance means includes: a first resistance part protruding from the upper parts of the strip bases and having an opening being open in a direction parallel to a longitudinal direction of the strip bases; and a second resistance part protruding from the lower parts of the strip bases and having an opening being open in an opposite direction to the opening of the first resistance part.

A soil reinforcing element for use in a mechanically stabilized earth structure. The soil reinforcing element may include a longitudinal wire including a helical portion and a connection element disposed at a first end of the longitudinal wire and configured to couple to a facing of the mechanically stabilized earth structure. The helical portion included in the longitudinal wire may introduce extensibility to the longitudinal wire under loading conditions.
