Abstract:
A connection device for fastening two expanded cellular confinement structures includes an insertion member having insertion ends, an insertion member extension, an integral shank, and a handle member. A cellular confinement system includes first and second webs of cells made from strips bonded together in spaced apart areas. The strips form walls of the cells and at least some of the cells define open slots. At least one connection device fastens the first web and the second web together through the open slots. A method of fastening two expanded cellular confinement structures includes aligning two expanded cellular confinement structures; inserting an insertion member of a connection device through open slots; and turning the connection device.
Abstract:
A clamping device for a portable porous pavement system includes a first bracket and a second bracket. The first bracket includes a U-shaped section extending between first and second wings; a first slot defined by the first wing; and a second slot defined by the second wing. The second bracket includes a C-shaped member having first and second arms with a base member joining the first and second arms; a first twistable section defined by the first arm; and a second twistable section defined by the second arm. The first arm is sized to fit through the first slot of the first wing such that the first twistable section and the base member are on opposite sides of the first wing; and the second arm is sized to fit through the second slot of the second wing such that the second twistable section and the base member being on opposite sides of the second wing.

Abstract:
A portable porous pavement system includes a plurality of porous pavement units and a plurality of clamping devices, in which each of the porous pavement units is connected to an adjacent porous pavement unit by at least one clamping device. Each clamping device includes a first bracket and a second bracket. The first bracket defines a slot arrangement. The second bracket is in intimate communication with the slot arrangement of the first bracket. The second bracket has a twisted arrangement to secure the second bracket and the first bracket together. Two adjacent walls of two adjacent porous pavement units are sandwiched between the first bracket and the second bracket to secure the two adjacent porous pavement units together. A method for assembling a portable porous pavement system includes providing first and second porous pavement units; mounting a C-shaped clamp member over two adjacent walls of the first and second porous pavement unit; orienting the first and second porous pavement units with the C-shaped clamp member on a surface; providing a locking bracket having a U-shaped section extending between first and second slotted wings; mounting the locking bracket over the C-shaped clamp member by orienting the U-shaped section over the two adjacent walls, with the first arm going through the first slotted wing and the second arm going through the second slotted wing; and twisting the first arm and the second arm to secure the locking bracket and the C-shaped clamp member around the first and second porous pavement units.
Abstract:
A cell material structure for confinement of concrete and earth material, having a plurality of plastic strips bonded together on their faces in a side by side relationship at bonding areas which are staggered from strip to strip such that the plurality of strips may be stretched in a direction perpendicular to the faces of the strips to form a web of cells, the strips forming cell walls. At least one of the strips has an aperture through which a reinforcing member extends. Preferably, the reinforcing member is a tendon made of a polymer having a nominal breaking strength of from about 100 to about 2,500 lb.
