Patent ID: 7441471

Claim:
A ground anchor load testing system comprising: a. A ground anchoring unit including an drilling shaft including: i. a first flanging end; ii. a drilling end; iii. a bare upper portion adjacent said first flanging end; and iv. a bottom portion adjacent said drilling end, said bottom portion featuring a push load ground transferring anchoring structure; b. A reaction anchor including a hollow shaft fitting around and along said bare upper portion, said hollow shaft including: i. A second flanging end; ii. A pull load ground transferring anchoring structure; c. A test loading head including: i. a first coupling that is at least axially push rigidly fitting on said first flanging end; ii. a second coupling that is at least axially pull rigidly fitting on said second flanging end; iii. a loading unit combined with said first coupling and said second coupling such that said first coupling is axially displace able with respect to said second coupling while: 1. said push load is created by said loading unit and transferred via said first coupling and said drilling shaft onto said push load ground transferring anchoring structure; 2. said pull load is created by said loading unit and transferred via said second coupling and said hollow shaft onto said pull load ground transferring anchoring structure; wherein said push load and said pull load are acting in substantially opposing direction and axially with respect to said drilling shaft and said hollow shaft; iv. an axial displacement indicator in axial connection with said first coupling, said axial displacement indicator externally accessibly references an axial ground anchor displacement of said drilling shaft while said push load is said transferred onto said drilling shaft, said axial ground anchor displacement being correlated to said push load; and d. A ground referencing axial displacement measurement device including: i. A ground contacting base; ii. An axial displacement recognition unit combined with said ground contacting base, such that said axial ground anchor displacement is recognized with respect to said ground by said ground referencing axial displacement recognition device.
