Publication number: 20240133147Abstract: 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.Type: ApplicationFiled: January 2, 2024Publication date: April 25, 2024Applicant: CMI LIMITED CO.Inventors: Steve HARGRAVE, Keith PANIK

Publication number: 20190338819Abstract: Example embodiments of the invention generally relate to a dampening and impact absorption device including a first component, a second component, and at least one elastomeric element operatively coupled between the first component and the second component. Other example embodiments of the invention generally relate to a dampening and impact absorption system including one or more such dampening and impact absorption devices. In example applications, the dampening and impact absorption device is utilized to dampen and reduce impacts, forces and noise between the platform and anchor pilings of a floating dock system, for example resulting from wave action or other dynamic effects.Type: ApplicationFiled: July 15, 2019Publication date: November 7, 2019Applicant: CMI LIMITED CO.Inventors: Allen Jason NAIL, Steve HARGRAVE, Charles BROWN

Patent number: 9745710Abstract: A convertible capping system and methods of use thereof for capping a top portion of a sheet piling wall or other structure. A top panel of the capping system includes a widthwise spaced array of longitudinally extending parallel connection ribs, and defines an initial width at least equal to or greater than an intended final width, whereby a user can cut the top panel down to a desired final width corresponding to the thickness of the wall. A pair of side flanges have engagement features configured to attach to the connection ribs of the top panel after adjusting the width of the top panel, to assemble the capping system. A wave diverter and/or structural reinforcement system can optionally be provided with the convertible capping system or sheet piling wall.Type: GrantFiled: April 12, 2016Date of Patent: August 29, 2017Assignee: CMI LIMITED CO.Inventors: Steve Hargrave, Ben Brown

Publication number: 20170030041Abstract: Improved systems, apparatus and methods for construction of slurry walls are provided. A sheet piling barrier is installed into a slurry wall construction to provide improved fluid barrier capability and/or structural integrity. A void creation device allows removal of cementitious material from around the engagement lock element of an installed sheet piling member to prevent interference with engagement of the engagement lock element of a subsequently installed sheet piling member after hardening of the slurry wall.Type: ApplicationFiled: July 28, 2016Publication date: February 2, 2017Applicant: CMI LIMITED CO.Inventors: Steve HARGRAVE, Brendan SHEPARD, Tony PARISE

Publication number: 20060010819Abstract: A retaining wall (10) is formed by a series of structural panels (18) arranged in edge-to-edge relationship, supported by horizontally extending wales (16) and vertically extending piles (14). The panels are formed of a rectangular board (40) with a plastic envelope (42) adhered to the board. Strips (60 and 61) are adhered to the plastic material at one edge portion of each panel, with the strips forming protruding lips (58 and 50) that receive the second edge of an adjacent panel, thereby guiding the new panels into place and forming a barrier to the movement of water and water borne debris between the panels.Type: ApplicationFiled: August 5, 2005Publication date: January 19, 2006Inventors: John Irvine, Steve Hargrave
