Abstract

A novel apparatus and method are disclosed for testing piles for load bearing capacity. The novel means and method of the present invention include applying a static compressive force on a pile or group of piles to be tested for load bearing capacity, receiving an equal and opposite reaction force on an I-beam, providing at least two reaction anchor assemblies on opposite sides of the pile, and bracing the I-beam by the two reaction anchor assemblies to hold the I-beam stationary in counter-action against the opposite reaction force on the I-beam. In one aspect, each reaction anchor assembly has an anchoring head, a pipe column, a center, a pulling rod passing through the center, a pair of the swingable anchoring plates, and a frusto-cone for pivoting the swingable anchoring plates. In one aspect, the pipe column has four fins welded longitudinally along the pipe column. In one aspect, the reaction anchor assembly is preassembled for transportation to a pile test site. The novel means and method retrieve the reaction anchor assemblies from the ground after completion of the pile test and reuse them from one pile test site to another.
