Load cell for ground anchors

摘要

There is provided a load cell for monitoring the residual forces in a pre-stressed soil and rock anchor, including a locking body having one hole through which a tensioning element passes, and an electronic bridge circuit containing strain-responsive elements affixed to the circumference of the locking body. The elements are oriented to detect changes in axial and circumferential dimensions of the locking body caused by changes in the residual forces of the soil and rock anchor,
