AI Technical Summary

Technical Problem

The existing highway tunnel crack depth measurement equipment has limited scope of application, and it is impossible to accurately measure non-horizontal cracks. Moreover, since the tampon cannot reach the bottom of the crack at the same time, the measurement error is large, which affects the tunnel crack condition evaluation and maintenance decisions.

Method used

A measurement assembly including a first measuring plate and a second measuring plate is designed, and the angle between the measuring plates is flexibly adjusted by the adjustment assembly, adapting to cracks of different shapes, and improving the accuracy of the measurement through a dual measurement method of the moving rod and the transducer.

Benefits of technology

Accurate matching and measurement of complex cracks is achieved, measurement errors are reduced, and the accuracy of evaluation of tunnel crack conditions is improved and maintenance decisions are made.

Abstract

The invention discloses highway tunnel crack depth measuring equipment and method, and relates to the technical field of tunnel crack measurement, the highway tunnel crack depth measuring equipment comprises a measuring assembly and a moving rod, first and second measuring plates of the measuring assembly are connected through an adjusting assembly, and the second measuring plates are symmetrically arranged on two sides of the first measuring plate and can rotate to adjust the angle so as to match the outer contour of a tunnel crack; the moving rod is inserted into the through hole of the measuring plate to form the inner contour of the crack, the adjusting assembly can enable the measuring plate to adapt to various crack shapes and improve the measuring adaptability, and the moving rod is matched with the measuring plate to visually present the depth and the inner shape of the crack. Meanwhile, the measuring method adopts the moving rod and the transducer for dual measurement, so that the limitation of single measurement is avoided, and the data accuracy is greatly improved; compared with a traditional measurement mode, the method effectively solves the problems of poor measurement adaptability and low data accuracy caused by complex crack forms, and provides a more reliable technical means for highway tunnel crack measurement work.
