Abstract:
To inspect a tensioning force of a tension device such as a ground anchor easily and efficiently.SOLUTION: A measurement circuit board 29 and a physical property sensor (a strain sensor) 23 are assembled into an anchor plate 37 of a ground anchor 3. The measurement circuit board 29 detects physical property change of the anchor plate 37 using the physical property sensor 23 to measure a tensioning force of the ground anchor 3 and transmits the measurement data to an outside by radio. The measurement circuit board 29 and the physical property sensor 23 are covered by protective materials 45, 47. On the protective material 45 of the measurement circuit board 29, a marker protrusion 49 exhibiting a position of the measurement circuit board 29 is provided.SELECTED DRAWING: Figure 3
