Subway shield tunnel lining quality high-precision rapid vehicle detection method and apparatus

Abstract

The invention discloses a subway shield tunnel lining quality high-precision rapid vehicle detection method and apparatus. The detection apparatus comprises an image acquisition module, a ground-penetrating radar module, a multi-sensor fusion positioning module, a laser range-finding module and an industrial personal computer, the image acquisition module comprises a linear array CCD industrial camera and an LED light source, the ground-penetrating radar module comprises a ground-penetrating radar antenna and a ground-penetrating radar host, and the multi-sensor fusion positioning module comprises an inertia measuring apparatus and an encoder. The method and apparatus can be used for automation and normalization detection of the shield tunnel lining quality of existed subway lines, the power failure operation is avoided, a maintenance skylight is not occupied, normal operation of the subway is not influenced, the detection efficiency is substantially improved, the detection time of disease types and positions is greatly shortened, the damage to the tunnel lining can be eliminated in time, and the safety operation of the subway and the life and property safety of people are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of subway public works system detection, and relates to a high-precision and fast vehicle-mounted detection method and device for the lining quality of a subway shield tunnel. Background technique [0002] With the sustained and rapid development of my country's national economy and the continuous acceleration of urban construction, the urban population has increased sharply, urban traffic has become increasingly congested, and the contradiction between urban transportation facilities and urban rapid development has become increasingly prominent. Due to its large carrying capacity, low impact on the urban environment, safety, punctuality, and convenience, underground rail transit has become an inevitable trend and choice for large and medium-sized cities in my country to improve public transport capacity. The shield tunneling method refers to a construction method that uses shield machines to excavate tunnel...

AI Technical Summary

Problems solved by technology

The present invention utilizes two different technical means of linear array CCD industrial camera and ground-penetrating radar to obtain high-definition images of the surface structure of the subway shield tunnel lining and geological images of the inner structure of the tunnel lining at the same time, so as to solve the shortcoming that the detection basis is too single, which can be used for detection personnel to provide a more complete and comprehensive view of the condition of the tunnel lining
