Optical fiber inclination measuring device and failure inclination measuring hole remeasuring method
The invention relates to an optical fiber inclinometry device and a failure inclinometry hole remeasurement method, the optical fiber inclinometry device comprises an inclinometry optical cable installed in a failure inclinometry hole, and the inclinometry optical cable comprises a metal seeker, a multi-core optical cable and an optical cable orifice protection head; the metal seeker is located at the lowermost end of the inclinometry optical cable and is conical. The multi-core optical cable is formed by compounding two ultra-weak grating optical fibers and a rubber material. And the optical cable orifice protection head is fixed at the pipe orifice of the failure inclinometer hole, and the inclinometer optical cable passes through the optical cable orifice protection head when going out of the orifice. According to the invention, the inclinometer optical cable is installed in the inclinometer hole which is failed but still has an internal space, the deep displacement monitoring function of the original hole position is recovered, no new damage is generated to the existing engineering structure, and the continuation of the monitoring data of the original hole can be realized.
一种光纤测斜装置及失效测斜孔复测方法，所述光纤测斜装置包括安装在失效测斜孔内的测斜光缆，所述测斜光缆包括金属导引头、多芯光缆、光缆孔口保护头；金属导引头处于测斜光缆最下端，金属导引头为圆锥形。多芯光缆由两根超弱光栅光纤与橡胶材料复合而成。光缆孔口保护头固定在失效测斜孔的管口，测斜光缆出孔口时穿过光缆孔口保护头。本发明将测斜光缆安装在已失效但尚有内部空间的测斜孔内，恢复原孔位置深部位移监测功能，不会对现有工程结构产生新的破坏，还可以实现原孔的监测数据的延续。
