Patent number: 6224295Abstract: To secure a polymeric strip (5) to a facing (10) of a reinforced soil structure, the strip (5) is circumflected about a plastics rod (4) and the circumflected strip and the rod are interposed between two or more blocks (1, 2) in a cavity (7) to retain the rod and thereby secure the strip (5) to the facing (10). The location of the rod (4) within the facing serves to distribute more uniformly the load imposed by the facing (10) on the strip (5), and the plastics rod (4) is resistant to corrosion.Type: GrantFiled: March 30, 1999Date of Patent: May 1, 2001Inventors: Derrick Ian Peter Price, Christopher Martin

Patent number: 6193445Abstract: A textile mesh for stabilizing earthen slopes and subgrades formed of interwoven, knitted, or stitch-bonded weft and warp elements that define a plurality of stable apertures of substantially uniform size by respective portions of the elements which have respective lengths of less than 12 millimeters. The textile mesh is coated with a curable material for interlocking the elements at junctions, whereby the textile mesh is rigidly flexible for facilitating handling during construction of a soil-stabilized earthen slope yet the junctions are substantially rigidly interlocked in order for the apertures to remain of substantially uniform size. The textile mesh is enclosed by layers of a backfill comprising particles of a size having an average diameter that is less than or equal to about 30% of the smaller of the lengths of the portions defining the apertures and at least 50% of which pass a number 4 sieve (4.75 mm).Type: GrantFiled: February 19, 1999Date of Patent: February 27, 2001Inventor: John M. Scales

Patent number: 6186703Abstract: An improved method and system for attaching a welded wire grid-work panel to a plurality of face panels of a retaining wall. The method first begins by providing a plurality of stackable face panels, each face panel having a plurality of anchor links fixed within a back portion of the face panels. Each of the anchor links forms a vertical loop extending outwardly generally perpendicular to the back portion of the face panels. Additionally, each anchor link includes two legs extending laterally from each anchor link within the face panel. Next, a first tier of the face panels is disposed at the bottom of the embankment being erected. Soil is then back-filled behind the first tier of panels to a level of the anchor links disposed within the first tier of face panels. A welded wire grid-work panel, which extends perpendicularly from the back portion of the face panels into a soil embankment, is positioned so that a plurality of wire loops at the edge of the grid-work panel aligns with the vertical loops.Type: GrantFiled: March 12, 1999Date of Patent: February 13, 2001Assignee: Shaw TechnologiesInventor: Kenneth L. Shaw

Patent number: 6174109Abstract: A retaining wall construction includes a first lower mechanically stabilized earthen bulk form with tensile members projecting from the front face of the first bulk form connected to precast wall panels that are spaced from the front face of the first bulk form. The space between the front face of the first bulk from and the panels is filled with concrete. Positioned on top of the concrete and the first bulk form, as well as along the sides thereof, are additional bulk forms which include tensile members connected to precast wall panels.Type: GrantFiled: March 17, 2000Date of Patent: January 16, 2001Assignee: Freyssinet International (Stup)Inventors: Eugene A. Lamberson, Sherif A. Aziz, Roger A. Bloomfield

Patent number: 6168351Abstract: A retaining wall anchoring system for a segmental retaining wall comprising a plurality of tieback rods adapted to be embedded into soil or rock with a proximal portion extending therefrom, at least one elongated force distribution member positionable directly adjacent the proximal portion of at least one of the tieback rods, a washer positionable about the proximal portions of the tieback rod in abutment with the force distribution member, and a fastener fixedly securable to the proximal portion of the tieback rod to securely clamp the washer against the force distribution member such that tensile forces imposed on the tieback rod are transmitted to the force distribution member so as to distribute these forces throughout a portion of the retaining wall.Type: GrantFiled: March 3, 1999Date of Patent: January 2, 2001Assignee: Anchor Wall Systems, Inc.Inventor: Thomas L. Rainey

Patent number: 6113317Abstract: A retaining wall system and method for stabilizing earthen walls comprises box members assembled together to form a reinforcing wall assembly and anchor mesh connected to the box members and buried within the earthen wall. The box members define an interior cavity and a rear wall that engages the face of the earthen wall. Waste material such as used tires or waste dirt may be placed within the interior chambers of the box members. The anchor mesh is attached to the rear wall to inhibit lateral movement of the reinforcing wall assembly. The box members are connected to the anchor mesh by locking pins that extend through loop portions of the anchor mesh and engage a front face of the wall panels. Anchor bars are connected to the loop portions of the anchor mesh. These anchor bars engage a back face of the box members to control and limit the movement of the box members relative to the anchor mesh as earth is back-filled against the box members.Type: GrantFiled: June 2, 1998Date of Patent: September 5, 2000Inventor: Clinton Charles Myers

Patent number: 6102118Abstract: A novel centralizer system adaptable to virtually all known rock and soil anchoring applications. Most preferably made from a petroleum based material, the primary components to the centralizer include a plurality of straps and two collars at opposite ends of the straps. The straps are easily and manually inserted into slots in each of the collars. Each collar may be molded to provide slots for three or more straps. The collars are molded with grout passages between slots thereby allowing more than the required amount of grout to be fed through the centralizer. On a least one strap are molded two lock hold pins distally located along an outer edge of the strap yet before the point where the strap is inserted into each collar. A separate yet component tool is manually and virtually simultaneously placed over both lock pins. The tool is a narrow band of material punched with a plurality of holes and placed over both lock hold pins.Type: GrantFiled: December 30, 1998Date of Patent: August 15, 2000Inventor: Curt A. Moore
