AI Technical Summary

Technical Problem

In existing technologies, laser rangefinders have large measurement errors when detecting local deformation of underground walls due to benchmark positioning deviations and contamination of the outer wall surface, making it impossible to accurately detect the local deformation of the wall.

Method used

The system employs a combination of reference supports and detection components, including vertically mounted main and auxiliary supports, balancing components, lifting sleeves, electric slide rails, and a multi-point array laser distance monitor. The accuracy of the laser rangefinder is ensured through precise positioning of the external reference supports and cleaning by the cleaning group.

Benefits of technology

The precise positioning of the reference support and the cleaning by the cleaning team reduced detection errors, improved the accuracy and efficiency of detecting local deformation of underground walls, and reduced the impact of soil pollution on the measurement.

Abstract

The present application relates to the technical field of underground wall deformation detection, in particular to a wall structure local deformation detection device and method, the detection device is used for detecting the deformation of the external corner of the underground wall of the sewage treatment plant, comprising a reference support vertically arranged at the external corner of the wall and a detection assembly installed on the reference support, the detection assembly comprises a liftable and rotatable electric slide rail, a multi-point array laser distance monitor and a cleaning group; the reference support is independently arranged at the external corner of the underground wall, and the balance member is used to first keep the main support and the auxiliary support forming a right angle track, and then the calibration assembly is used to fine-tune the reference support, so as to reduce the angle deviation between the right angle track and the external corner, reduce the error of the local deformation detection of the wall structure, the multi-point array laser distance monitor and the cleaning group move synchronously, which can shorten the detection time and reduce the influence of soil adhesion on the wall deformation detection, and the detection error is reduced through the two improvements.
