Background Art
[0002] Most of the existing monitoring devices for pile hole inclination and deviation of pile foundations passing through karst cave development areas use inclinometers for detection. Inclinometers are instruments used to measure the top angles and azimuths of engineering structures such as boreholes, foundation pits, foundations, walls and dam slopes. They are widely used in the fields of water conservancy and hydropower, mineral metallurgy, transportation and urban construction geotechnical engineering, and play an important role in ensuring the safety of geotechnical engineering design, construction and use.
[0003] The manual operation of pulling the cable and measuring head can flexibly and instantly control the rise and stop of the probe.
