Abstract
Abstract A steel cable anchor comprises a plurality of individual steel cables bundled together to form a steel cable anchor adapted to be embedded within the ground by being buried in a hole filled with a hardening material such as cement. One or more of the individual steel cables have their surfaces coated with an antifriction material. The remaining individual steel cables have their surfaces free of such anti-friction material. The method for withdrawing the steel cable anchor from its embedded position in the ground comprises the steps of first withdrawing one or more of the individual steel cables whose surfaces are coated with the anti-friction material and then withdrawing the remaining elemental steel cables whose surfaces are free of such anti-friction material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
89 words
A method for withdrawing a steel tension cable anchor embedded within hardening material in the ground, said cable anchor including a plurality of individual tension steel cables assembled in a bundle of cables, some but not all of said cables having their surfaces coated along at least the effective length thereof with an anti-friction material, the method comprising the steps of first withdrawing from said hardening material at least one individual cable whose surface is coated with said antifriction material, and thereafter withdrawing the remaining individual steel tension cables.
Claim 2
Independent Claim
89 words
A method for withdrawing a steel tension cable anchor embedded within hardening material in the ground, said cable anchor including a plurality of individual tension steel cables assembled in a bundle of cables, some but not all of said cables having their surfaces coated along at least the effective length thereof with an anti-friction material, the method comprising the steps of first withdrawing from said hardening material at least one individual cable whose surface is coated with said antifriction material, and thereafter withdrawing the remaining individual steel tension cables.
Claim 3
Dependent Claim
28 words
The method of claim 1, wherein all the individual steel cables coated with anti-friction material are removed from said bundle prior to removing any un-coated individual steel cables.
Claim 4
Independent Claim
124 words
A method of assemblying a steel tension cable anchor comprising coating the surface of at least one individual steel cable with anti-friction material along a length thereof, positioning said at least one coated cable in lengthwise proximity to at least one cable not coated with an anti-friction material, binding said coated and un-coated cables into a bundle, providing a hole in the ground and inserting said bundle therein, filling said hole with a hardening material to cover said bundle up to a length substantially corresponding to the length of individual cable coated with anti-friction material, leaving one end of said coated and un-coated cables to protrude from said hardening material, and securing the protruding ends of said cables to a structure to be anchored.
Claim 5
Independent Claim
124 words
A method of assemblying a steel tension cable anchor comprising coating the surface of at least one individual steel cable with anti-friction material along a length thereof, positioning said at least one coated cable in lengthwise proximity to at least one cable not coated with an anti-friction material, binding said coated and un-coated cables into a bundle, providing a hole in the ground and inserting said bundle therein, filling said hole with a hardening material to cover said bundle up to a length substantially corresponding to the length of individual cable coated with anti-friction material, leaving one end of said coated and un-coated cables to protrude from said hardening material, and securing the protruding ends of said cables to a structure to be anchored.
Claim 6
Dependent Claim
21 words
The method of claim 3, wherein only the cables without anti-friction material thereon are secured to said structure to be anchored.
Claim 7
Dependent Claim
25 words
The method of claim 3, further including attaching fixing means to the protruding portion of said cables and positioning said fixing means adjacent a revetment.
