Description

technical field [0001] The invention belongs to the field of deep horizontal displacement monitoring, and relates to an inclinometer, in particular to a double-tube fully automatic layered inclinometer system and an inclinometer method. Background technique [0002] Deep horizontal displacement monitoring is often used in the monitoring of deep foundation pits, vacuum preloading areas, dams, wharves and other structures. It is one of the main means to understand the deep changes of deep foundation pits, slopes and foundation soil. [0003] The inclinometer is mainly composed of a pre-buried inclinometer tube, a probe, a control cable, a pulley device and a reading instrument. The initial data of the displacement of the inclinometer tube can be recorded for the first observation. Subsequent observations will show changes in section displacement as the ground moves. When observing, the probe moves from the bottom to the top of the inclinometer pipe, pauses at every half-meter...

AI Technical Summary

Problems solved by technology

[0005] At present, the traditional inclinometer method is manual operation. First, the probe is lowered to a predetermined depth, and then measured from bottom to top. Areas such as the mud accepting area are greatly affected by the harsh natural environment, and there may be safety risks; data collection is greatly affected by the environment, and the continuity is poor; in addition, each measurement requires a rise or fall of 50cm, which cannot be accurately controlled by manual measurement, which will bring great harm. Large deviations lead to unavoidable human errors in the measurement data, and the accuracy is low; in addition, the frequency of manual monitoring is low, the monitoring data is lagging, and the real-time performance is poor; it is greatly affected by the interference of construction operations, and the data cannot be shared.

[0006] At present, the fixed inclinometer that has been studied more is to use the inclination sensor to measure and convert the displacement data, because the precision required by the fixed inclinometer is higher (the angle error is not greater than 0.005 degrees), and each sensor is expensive and affected by temperature. The impact is large, and the installation distance is too much affected by the cost (the distance is 1 ~ 2m), so the installation cannot meet the accuracy and specification requirements. In addition, the fixed sensor cannot eliminate zero drift, temperature drift and equipment. error, and this error is generally large and has a certain degree of randomness, which cannot be effectively eliminated, resulting in unsatisfactory measurement results, and even deviates from the actual soil displacement

[0007] Some scholars also try to adopt the automatic one-way sliding type, but they cannot eliminate and reduce the influence of the instrument's zero drift, temperature drift, instrument error and assembly error.

[0008] The above-mentioned traditional methods have not proposed a substantial solution to the problems of how to reduce the influence of errors, reduce costs, and control the sliding travel distance of the instrument.
