Introduction

Drilling inclinometer is mainly used for geological disaster monitoring, highway bridge foundation safety monitoring, hydropower dam monitoring, earthquake Forecasting and other fields. This specification is written in accordance with JJF 1083-2002 "Optical Tiltometer Calibration Specification". This specification is the first release. Drilling inclinometer calibration specification

1 Scope

This specification applies to the measurement range of -30 ° ~ 30 °, the maximum allowable error of ± 0.025% FS based on gravity plus Speed sensor inclinometer calibration, other inclinometer can refer to the implementation.

2 reference file

This specification refers to the following documents. JJF 1083-2002 optical inclinometer calibration specification For dated references, only the dated edition applies to this specification; references that are not dated , The latest version (including all modifications) applies to this specification.

3 Overview

Drilling inclinometer is based on the vertical direction by gravity, gravity acceleration sensor output voltage linearly corresponding to The vertical direction of the sensor after the tilt angle of the acceleration component (cosine component), the same can be converted into horizontal displacement Component (sine component). From the structure can be divided into two kinds. deep and slip type. The submerged borehole inclinometer installs the acceleration sensor In the probe, dozens of drill inclinometers are permanently fixed in the array to monitor the key position. Slip drilling The inclinometer can be measured along the vertical buried pipe, the angle between the axis of the measuring probe (probe) and the vertical line of gravity, Is the drilling angle. The amount of change in the tilt angle from the meter (display device) for data collection, the computer software Statistical analysis can directly or indirectly reflect the stability of the geological structure. This type of instrument is mainly used for geological disaster monitoring Measurement, highway bridge foundation safety monitoring, hydropower dam monitoring, earthquake prediction research and other fields. Drilling inclinometer typical structure shown in Figure 1. Figure 1 Schematic diagram of drilling inclinometer Measurement model. Xi = Lsinαi
