Zusammenfassung: | To provide a borehole inclinometer device that can properly measure an underground inclination change over a long period, as suppressing damage of an inclinometer main body embedded underground.SOLUTION: A borehole inclinometer device 1 for measuring an underground G inclination change, comprises: a plurality of unit pipes 11 that are formed into cylinders each made of a prescribed kind of a metal material, and are embedded underground G in a state with the unit pipe coupled to each other in a length direction; a plurality of inclination sensors that are built in each of the plurality of unit pipes 11, and detect respectively an inclination angle of the corresponding unit pipe 11; a plurality of azimuth sensors that are built in each of the plurality of unit pipes 11, and detect respectively an azimuth of the corresponding unit pipe 11; and a plurality of connection pipes 16 that are formed into cylinders each composed of a material softer than the unit pipe 11 and having a prescribed length, and are fixed to mutually facing end parts of the unit pipes 11 to be coupled in a state where each of the plurality of connection pipes is inserted to the end part thereof.SELECTED DRAWING: Figure 3
【課題】地中に埋設された傾斜計本体の破損を抑制しながら、地中の傾斜変動を長期にわたって適切に計測することができる孔内傾斜計装置を提供する。【解決手段】地中Gの傾斜変動を計測するための孔内傾斜計装置1であって、各々が所定種類の金属材料から成る筒状に形成され、互いに長さ方向に連結された状態で地中Gに埋設された複数のユニット管11と、複数のユニット管11の各々に内蔵され、対応するユニット管11の傾斜角度をそれぞれ検出する複数の傾斜センサと、複数のユニット管11の各々に内蔵され、対応するユニット管11の方位をそれぞれ検出する複数の方位センサと、各々がユニット管11よりも軟質の材料で構成されるとともに所定長さを有する筒状に形成され、連結すべきユニット管11の互いに対向する端部にそれぞれ挿入された状態で固定された複数の連結管16と、を備えている。【選択図】図3 |
