Geotechnical Monitoring Inclinometer Real Time Slope Monitoring Landslide Inclination Monitoring Instrument Slope Movement Stability Inclinometer
Foundation pit displacement inclinometer (Engineering inclinometer) is an instrument to determine the displacement by precise measurement of inclination angle. It is mainly used to monitor the horizontal displacement of deep foundation pit, slope, foundation, pier and other foundations during the observation period.
When the foundation pit, slope and foundation are deformed, the inclinometer tube will be deformed. The pulley on the inclinometer probe will be measured point by point along the groove, so that the horizontal displacement can be accurately measured. According to the value of horizontal displacement, the prediction is made to guide the construction; When measuring the pier, the inclinometer head is fixed on the pier to monitor the inclination change of the pier.
1. The inclinometer consists of an inclinometer probe, a ground controller, a charger, and a cable with depth marks.
2. Adopt the working mode of collecting data by depth marking fixed-point measurement on the outdoor site, and indoor analysis and processing to form a map.
3. The control unit can record the measurement data of 60 monitoring boreholes at a time. The measurement data is transmitted from the control unit to the computer, and then the computer analyzes the data processing, data sorting and printing out the map.
4. The measurement data is reliable, easy to operate, and suitable for various outdoor environments. It is a common measuring instrument for monitoring the displacement of foundation pits, slopes and foundations.

1. Surface displacement monitoring technology
The surface displacement monitoring technology can be divided into three categories according to its measuring methods: measuring point type, measuring line type and measuring surface type.
Point type
Measuring point type technology is mainly concerned with the change of relative displacement between two points. By laying a large number of measuring point type monitoring instruments on the surface of the landslide, it can also monitor the displacement of a certain line and surface of the landslide. The measuring point type equipment has high precision, which is suitable for accurately detecting the displacement of the key point of the landslide, and provides a basis for accurate analysis of the stable state of the landslide. Measuring point type equipment mainly includes GPS, automatic total station, pull line type surface displacement meter, etc.
Linear measurement
Linear measurement technology is mainly concerned with the deformation of each point on a line, and the signal transmission line of such equipment is the data sensor element. Compared with the measuring point type equipment, this kind of equipment can find out the deformation status of any position within the measuring line range, and the sensing circuit is conveniently arranged, but the monitoring accuracy is lower than the measuring point type equipment.
2. Deep displacement monitoring technology
Deep displacement monitoring technology can be divided into two types according to its measurement methods: point-type measurement and line-type measurement.
Point type
Borehole inclinometer and draw-line deep displacement meter are typical point-type deep displacement monitoring techniques. This kind of technology uses fixed probe or movable probe as sensing element to sense the change of position displacement of measuring point through the probe.
Linear measurement
Linear monitoring technology mainly refers to the accurate detection of the lateral displacement of any point in the measuring line by distributed sensing elements. TDR technique is the most typical technique for deep displacement monitoring of linear. After the monitoring data of surface displacement and deep displacement are converted into electrical quantities, they are converted into digital signals through analog-to-digital converters and sent to remote terminals in GSM, GPRS, 3G or Beidou navigation satellite communication mode.
