Automatic measuring device used for horizontal displacement of rock soil and using method of automatic measuring device

Abstract

The invention discloses an automatic measuring device used for horizontal displacement of rock soil and a using method of the automatic measuring device. The measuring device comprises a protective barrel which is of a hollow structure, a guide wheel structure and an inner data acquisition and processing part, wherein the protective barrel is divided into an upper guide wheel protective barrel, amiddle sensing part protective barrel and a lower guide wheel protective barrel; the guide wheel structure is arranged in the protective barrel and comprises an upper guide wheel structure and a lowerguide wheel structure that are arranged at an interval; the inner data acquisition and processing part is arranged in the middle sensing part protective barrel and comprises a sensing module, a micro-processing module, a communication module and a power supply module; wherein, an antenna is arranged at the top end of the upper guide wheel protective barrel and is electrically connected with the communication module. According to the measuring device provided by the invention, a measuring manner of tandem type static fixed inclination measurement can be simulated, so that the accuracy of datais ensured; in addition, the measuring device does not need to be in wired connection with an external device, so that the abrasion of cables is avoided, and the waterproof problem does not need to besolved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering deformation monitoring, in particular, the invention relates to an automatic measurement device for horizontal displacement of rock and soil and a use method. Background technique [0002] With the continuous rise of industrial and civil construction projects, the current engineering projects have become more and more strict on the quality control of the project, and the safety construction management in the construction process has played a vital role. Deep horizontal displacement is a key monitoring item for most projects, especially foundation pit projects. However, so far, the traditional deep horizontal displacement measurement method is still manual lowering and lifting of the portable inclinometer, and manual measurement. In some projects, automated measurement methods have begun to be used, including serial static fixed inclinometers and split static fixed inclinometers. ...

AI Technical Summary

Problems solved by technology

The main problem of this method is that the sensor cannot be recycled, which is a one-time hardware investment, and the cost is high. In addition, the more critical point is that due to the non-rigid connection between the sensor and the sensor, the impact of local micro-deformation on data accumulation is not considered. After data accumulation There will be a large error, and the measured data does not have high reliability
