GROUND DISASTER DETECTOR, GROUND DISASTER DETECTION METHOD, AND GROUND DISASTER NOTIFICATION SYSTEM
PROBLEM TO BE SOLVED: To provide a ground disaster detector capable of precisely and swiftly detecting the possibility of ground disaster for long period of time without requiring a large cost, and to provide a ground disaster detection method and a ground disaster notification system using the ground disaster detector.SOLUTION: The ground disaster detector includes: a hollow pipe body member 10 which is embedded in the underground; and three or more piezoelectric elements 20a-20c which are disposed at a uniform distances in a peripheral direction on the inner wall of the body member 10. Each of the piezoelectric elements 20a-20c receives a stress due to a deformation of the body member 10 and outputs an electric signal.
【課題】大きなコストを必要とせず、長期間、高精度且つ迅速に、地盤災害の有無を把握することができる地盤災害検出装置を提供し、さらに、該地盤災害検出装置を用いた地盤災害検出方法及び地盤災害通報システムを提供する。【解決手段】地中に埋設される中空パイプ状の本体部材１０と、該本体部材１０の内壁に、周方向に等間隔で３箇所以上配設された圧電素子２０ａ〜２０ｃを有し、それぞれの前記圧電素子２０ａ〜２０ｃが、前記本体部材１０の変形による応力を受けて電気信号を出力することを特徴とする。【選択図】図１
