  • Publication number: 20240133147
    Abstract: A retaining wall system, retaining wall panel, and method of constructing a retaining wall, wherein panels of the retaining wall may define an arched or curved profile in plan view, for example following a catenary curvature, with the wall panel curvature being concave in a direction extending into the backfill area behind the retaining wall. The curvature resists backfill loading on the panel and evenly distributes the load across the panel without significant stress concentrations and transfers the load to posts or columns to which the panels are mounted. A wall panel having a post attachment flange on one side for attachment to one post, and a post surround channel on the other side for at least partially surrounding another post. The system may optionally include one or more composite polymeric posts for supporting the panels.

  • Publication number: 20210164187
    Abstract: A sheet piling filler-corner member includes one or more female couplings for engagement of male couplings of connected sheet pilings, and one or more male coupling members for engagement within female couplings of connected sheet pilings. Selective attachment of sheet pilings using the filler-corner member, and/or modification of the filler-corner member into different configurations allows the filler-corner member to universally function as a spacer or filler for adding length to a sheet piling assembly, as a corner coupling, or as a gender-change adapter between sheet pilings.
