Panel system for slope protection

Claim 1

A system of panels and accessory anchoring devices for providing erosion protection to the slopes of a watercourse, including: a plurality of panels of a weight such that each is man portable, and designed to be placed vertically one upon the other along a watercourse slope; said panels each being made of a plurality of hollow sections designed and constructed to mate with each other, each of said sections being extruded in a hollow rectangular configuration from light weight material, the mating surfaces of the sections carrying interlocking, longitudinally extending tongue and groove means thereon, and the hollow interiors thereof accommodating the reception of other material and items within the sections and the panels formed thereby; a plurality of deadman elements, for burying in the earth fill placed behind each panel; and means connecting said deadman elements with the rear sides of said panels, whereby when said deadman elements are buried in the earth fill said panels will be secured in position.

Claim 2

A system of panels and accessory anchoring devices for providing erosion protection to the slopes of a watercourse, including: a plurality of panels of a weight such that each is man portable, and designed to be placed vertically one upon the other along a watercourse slope; said panels each being made of a plurality of hollow sections designed and constructed to mate with each other, each of said sections being extruded in a hollow rectangular configuration from light weight material, the mating surfaces of the sections carrying interlocking, longitudinally extending tongue and groove means thereon, and the hollow interiors thereof accommodating the reception of other material and items within the sections and the panels formed thereby; a plurality of deadman elements, for burying in the earth fill placed behind each panel; and means connecting said deadman elements with the rear sides of said panels, whereby when said deadman elements are buried in the earth fill said panels will be secured in position.

Claim 4

A system of panels and accessory anchoring devices for providing erosion protection to the slopes of a watercourse, including: a first, bottommost vertical panel having a weight such that it is man portable, said first panel being placed at the edge of the bed of said watercourse; a first layer of earth fill, placed behind said bottommost vertical panel and generally level with the top thereof; a second panel placed atop said first panel and engaged therewith, said second panel also having a weight such that it is man portable; said panels each being made of a plurality of hollow sections designed and constructed to mate with each other, each of said sections being extruded in a hollow rectangular configuration from light weight material, the mating surfaces of the sections carrying interlocking, longitudinally extending tongue and groove means thereon, and the hollow interiors thereof accommodating the reception of other material and items within the sections and the panels formed thereby; at least one deadman element placed upon said first layer of earth fill, rearwardly of said first and second panels; means connecting said deadman element with at least said second panel, including a tie member having on one end thereof a wedge-shaped element receivable in the interlocking grooves on said sections; and a second layer of earth fill, placed upon said first layer behind said second panel, and covering said deadman element and said connecting means.

Claim 5

A system of panels and accessory anchoring devices for providing erosion protection to the slopes of a watercourse, including: a first, bottommost vertical panel having a weight such that it is man portable, said first panel being placed at the edge of the bed of said watercourse; a first layer of earth fill, placed behind said bottommost vertical panel and generally level with the top thereof; a second panel placed atop said first panel and engaged therewith, said second panel also having a weight such that it is man portable; said panels each being made of a plurality of hollow sections designed and constructed to mate with each other, each of said sections being extruded in a hollow rectangular configuration from light weight material, the mating surfaces of the sections carrying interlocking, longitudinally extending tongue and groove means thereon, and the hollow interiors thereof accommodating the reception of other material and items within the sections and the panels formed thereby; at least one deadman element placed upon said first layer of earth fill, rearwardly of said first and second panels; means connecting said deadman element with at least said second panel, including a tie member having on one end thereof a wedge-shaped element receivable in the interlocking grooves on said sections; and a second layer of earth fill, placed upon said first layer behind said second panel, and covering said deadman element and said connecting means.
