How to Install Digital Inclinometer in a Borehole? Borehole Drilling Start by drilling a 125mm hole around 0.5m more than the planned depth of the inclinometer casing. (Try keeping the hole as vertical as possible) The diameter of the drill hole should facilitate grouting around outside of the casing. See more Casings must be grouted as directed by project authorities. Ideally, grout should be mixed to match the strength and deformation characteristics of material around the borehole. … See more Check installed access tubing by dummy probe (EAN-26) for smooth movement up to the bottom of the borehole.

WebSlope inclinometers are geotechnical instruments used to measure horizontal displacements along various points on a borehole. For this reason, sometimes they are also called borehole inclinometers or simply inclinometers. Slope inclinometers are the most important source of geotechnical data during construction (Erikson et. al., 1992). WebA borehole inclinometer is an example of the established method to monitor such ground movements. For real-time data, a series of in-placed inclinometer probes are installed inside the borehole casing to provide the lateral displacement response over time. The limitation of the conventional system is the high cost and the practicality of ...
WebBorehole inclinometer. The digital inclinometer probe is used for section-by-section displacement measurements radial to the axis of the measuring tube. The probe has a base length of 0.5 or 1.0 m. The vertical inclinometer is used in vertical boreholes and the horizontal inclinometer in horizontal boreholes. These probes can be integrated into ... WebMeasurements from the deepest part of an inclinometer casing have the highest potential for systematic errors due to four factors: (1) instrument warm-up drift being most acute, (2) calibration hysteresis more probable, (3) tendency of the borehole to drift from vertical, and (4) greatest distance from the top reference point.
