Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
127 words
An embankment shoring structure comprising a cast foundation, a number of prefabricated reinforced concrete panels disposed substantially vertically side by side on the foundation so as to form a supporting wall, a cast reinforced concrete anchoring bed extending upwards from the bottom of the supporting wall so as to form a unitary structure having a substantially L-shaped transverse section, and a rigid brace connected to each panel, each brace when installed on site being fixed at one end to the wall of the panel facing the material to be supported and the opposite end of the brace being embedded in the anchoring bed, wherein the brace comprises a curved arm the concave side of which faces towards the material to be supported, away from the supporting wall.
Claim 2
Dependent Claim
127 words
An embankment shoring structure comprising a cast foundation, a number of prefabricated reinforced concrete panels disposed substantially vertically side by side on the foundation so as to form a supporting wall, a cast reinforced concrete anchoring bed extending upwards from the bottom of the supporting wall so as to form a unitary structure having a substantially L-shaped transverse section, and a rigid brace connected to each panel, each brace when installed on site being fixed at one end to the wall of the panel facing the material to be supported and the opposite end of the brace being embedded in the anchoring bed, wherein the brace comprises a curved arm the concave side of which faces towards the material to be supported, away from the supporting wall.
Claim 3
Dependent Claim
36 words
Shoring structure as defined in claim 1, wherein the ratio between the radius of curvature (R) of the brace and the height (H) of the panel to which it is connected is between 1 and 5.
Claim 4
Dependent Claim
23 words
Shoring structure as defined in claim 1, wherein the radius of curvature (R) of the curved brace is between 15 and 25 meters.
Claim 5
Dependent Claim
20 words
Shoring structure as defined in claim 1, wherein the curved brace has a radius of curvature of substantially 20 meters.
