<p>PROBLEM TO BE SOLVED: To detect abnormality of the ground, a building, and the like, quickly by measuring the physical geographic displacement thereof with high accuracy. SOLUTION: A tubular body 1 being buried under the ground is formed by coupling a plurality of tubular parts 1a of appropriate length depending on the burying depth, A detecting section comprising a clinometer 3 and a vibrometer 4 for the axes of three-dimensional solid gyrosensors 2, 3 is disposed in the tubular body 1 through a supporting plate 1b secured to the inner wall face of the tubular part 1a. A drive power supply, i.e., a battery 5, the gyrosensor 2, a section 6 for amplifying and operating detection signals from the clinometer 3 and the vibrometer 4, and a section 7 for transmitting the detection signal processed at the operating section 6 are disposed in the tubular part 1a through the supporting plate 1b secured to the inner wall face of the tubular body 1.</p> |
