ABSTRACT:
Pile testing apparatus and method apply static compressive forces on a pile to be tested for load bearing capacity. Retractable and reusable reaction anchor assemblies are installed into the ground for pile testing and then are retrieved from the ground after completion of the pile testing and are reused from one pile test site to another. The invention operates to receive an equal and opposite reaction force on an I-beam and provide at least two retractable and reusable reaction anchor assemblies installed into the ground at a depth significantly less than required with conventional pile testing methods. The I-beam is braced by the two retractable and reusable reaction anchor assemblies and held stationary in counter-action against the opposite reaction force on the I-beam. The pile testing apparatus and method of the present invention reduce costs considerably and can be used immediately as contrasted to conventional methods using concrete.
