Measuring for Success
There is a direct correlation between installation torque and the capacity a helical can achieve. Therefore, it is imperative to accurately measure the torque values for each pier or anchor as it is installed. Even as a geotechnical report indicates the likely depth at which helicals will obtain capacity, borings are rarely taken at every pile location. Torque logs provide in-field verification that helical piers and anchors have been installed to the depth necessary to achieve their ultimate capacity.
The Best Advice From the Experts
As with other helical pile installation equipment, you want to select a torque indicator that is compatible with the type of work that you do. Popular torque indicators include a shear pin indicator, a differential pressure indicator, a digital torque indicator, and strain gauge technology; they can be synced with other devices through Bluetooth. A simple gauge indicating pounds per square inch can also be used along with a conversion chart indicating torque. Danbro sells a variety of torque indicators and will advise you on the best choice for you and your work.
