Abstract
Abstract A structure for stablizing an earth mass, particularly an embankment. The structure includes elongated reinforcement members having transverse ribs for enhancing frictional engagement with the adjacent earth. The structure also includes skin or facing elements with brackets for connecting the reinforcement members to the skin elements. The connection between the brackets and the reinforcement members is arranged to minimize the effects of corrosion.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
117 words
A stabilized earth structure comprising a mass of earth, a plurality of reinforcing elements embedded in the mass, said reinforcing elements being elongated and pliable and being capable of sustaining tension without permanently elongating and without fracture, a portion of said earth being in direct frictional engagement with one surface of said reinforcing elements, said one surface having a plurality of ribs spaced apart longitudinally of said element, said ribs having a height of about 3 millimeters, said earth being pressed against said one surface with sufficient pressure to be retained by said ribs and to become an integral part of said reinforcing element, and thereby increasing frictional resistance between said earth mass and said reinforcing elements.
Claim 2
Dependent Claim
117 words
A stabilized earth structure comprising a mass of earth, a plurality of reinforcing elements embedded in the mass, said reinforcing elements being elongated and pliable and being capable of sustaining tension without permanently elongating and without fracture, a portion of said earth being in direct frictional engagement with one surface of said reinforcing elements, said one surface having a plurality of ribs spaced apart longitudinally of said element, said ribs having a height of about 3 millimeters, said earth being pressed against said one surface with sufficient pressure to be retained by said ribs and to become an integral part of said reinforcing element, and thereby increasing frictional resistance between said earth mass and said reinforcing elements.
Claim 3
Dependent Claim
22 words
A stabilized structure according to claim 1 wherein the height of the ribs is less than the thickness of the reinforcing element.
Claim 4
Dependent Claim
19 words
A stabilized structure according to claim 1 wherein the ribs are perpendicular to the length of the reinforcing elements.
Claim 5
Dependent Claim
21 words
A stabilized earth structure according to claim 1 wherein the ribs extend obliquely to the longitudinal axis of the reinforcing element.
Claim 6
Dependent Claim
15 words
A stabilized earth structure according to claim 1 wherein the ribs have a chevron shape.
Claim 7
Dependent Claim
35 words
A stabilized earth structure according to claim 1 wherein said reinforcing element has a surface opposite to said one surface, and said opposite surface has a plurality of ribs spaced longitudinally of said reinforcing element.
Claim 8
Dependent Claim
25 words
A stabilized earth structure according to claim 6 wherein said ribs on said opposite surface are longitudinally offset from said ribs of said one surface.
Claim 9
Dependent Claim
136 words
In a stabilized earth structure of the type having a plurality of reinforcing elements embedded in a mass of earth, said mass having a face along at least one side of the mass, said reinforcing elements being elongated and pliable and being capable of sustaining tension without permanently elongating and without fracture, said earth mass being in direct frictional engagement with opposed surfaces of said reinforcing elements, the improvement wherein said opposed surfaces reinforcing elements have a plurality of transverse ribs spaced apart longitudinally of said elements, said ribs having a height of about 3 millimeters, said ribs on one surface of a reinforcing element being longitudinally offset from the ribs on the opposite surface of said element, said earth mass filling the space between said ribs and engaging substantially the entirety of said opposed surfaces.
Claim 10
Dependent Claim
136 words
In a stabilized earth structure of the type having a plurality of reinforcing elements embedded in a mass of earth, said mass having a face along at least one side of the mass, said reinforcing elements being elongated and pliable and being capable of sustaining tension without permanently elongating and without fracture, said earth mass being in direct frictional engagement with opposed surfaces of said reinforcing elements, the improvement wherein said opposed surfaces reinforcing elements have a plurality of transverse ribs spaced apart longitudinally of said elements, said ribs having a height of about 3 millimeters, said ribs on one surface of a reinforcing element being longitudinally offset from the ribs on the opposite surface of said element, said earth mass filling the space between said ribs and engaging substantially the entirety of said opposed surfaces.
Claim 11
Dependent Claim
25 words
The stabilized earth structure according to claim 8 wherein said opposed surfaces are substantially flat between said ribs, and said ribs are of equal height.
Claim 12
Dependent Claim
23 words
The stabilized earth structure according to claim 8 wherein said ribs are thicker at their base than at their tip to resist deflection.
Claim 13
Dependent Claim
21 words
The stabilized earth structure according to claim 8 wherein said reinforcing elements have a thickness of between 5 and 12 millimeters.
