Inclinometers are generally composed of a probe, a cable assembly, a reading device, accessories, etc.
The sliding inclinometer adopts a forward and reverse measurement method, and the forward and reverse measurement method comprises the following steps: the inclinometer is embedded in the monitoring body in advance. During the measurement, the measuring head is transferred from the upper end of the pipe orifice of the inclinometer pipe, then the measuring head is lifted from bottom to top, the lifting process is used for measuring according to the specified measuring interval, and the inclination displacement is recorded once when the measuring interval is lifted. And after the measurement is finished by one stroke, the measuring head is rotated by 180 degrees and then is placed into the inclination measuring tube again, the measuring head is lifted from bottom to top, and the inclination displacement is recorded once every time the measuring head is lifted by one measurement interval. And accumulating the inclined displacements of all the depth sections, and performing corresponding data processing to finish measurement to obtain all the deep displacements of the inclinometer.
According to the use requirement of the inclinometer, when reading each measurement interval, the mark and the inclinometer pipe opening need to be aligned, and whether the alignment is accurate or not directly influences the measurement data. When the cables are aligned, the cables are required to lean against an inclinometer pipe orifice, the inclinometer pipe is made of PVC (polyvinyl chloride), ABS (acrylonitrile butadiene styrene) or aluminum alloy, and the pipe orifice is sharp and is easy to cut the cables. In the measuring process, the cable is easy to deviate from the central axis of the inclinometer pipe when being lifted, and the displacement measuring precision is influenced. In the measuring process, when the measuring head lifts measured data from bottom to top, the inclinometer falls off frequently due to improper operation.
