ABSTRACT:
A ground anchor load testing system includes a ground anchoring unit having a bare upper drill shaft portion along and around which a reaction anchor with its hollow shaft is temporary installed. During test loading of the installed ground anchoring unit, a test loading head is coupled with both concentric flanging ends of the ground anchoring unit and the temporarily installed reaction anchor. The test loading head exerts via a first coupling the push test load on the first flanging end of the ground anchoring unit while withholding itself via a second coupling on the second flanging end of the reaction anchor. A measurement device may be positioned on the ground adjacent the test load head. Eventual axial displacement of the ground anchoring unit under test load may be externally recognized by the measurement device via an axial displacement indicator in axial connection with the first coupling.
