Abstract: Embodiments of the subject invention are directed to a method and apparatus for measuring torque applied during installation of a helical pile. Specific embodiments relate to a helical pile installation torque measuring and monitoring system for use during helical pile installation. In a specific embodiment, a load cell pin, or torque pin, is incorporated into the drive head and equipment attachment to measure the direct forces, or torque, that is being applied by the drive head as the helical pile is rotated into the ground. The direct forces, or torque, are relayed to a data capturing device, which records the data and, optionally, displays one or more of the following: the forces, the torque created by the forces, the inclination angle of installation, and the downward, or longitudinal, force applied to advance the helical pile.

Abstract: Embodiments pertain to a bi-directional testing method and apparatus for use with a pile. One embodiment utilizes a helical pile central shaft divided into two sections. An expandable bi-directional testing apparatus that includes a sacrificial hydraulic jack, such as, for example, an Osterberg Cell®, that can be installed within the central shaft between the two sections. One or more tell tale rods can be attached to the bi-directional testing apparatus. During testing, expansion of the Osterberg Cell® causes the bi-directional testing apparatus to expand, which can result in movement of the one or more tell tale rods. The movement of the tell tale rods can be correlated to the force exerted by the Osterberg Cell® and provide information regarding the status load bearing capacity of the helical pile.
