Abstract

The invention discloses a rapid and comprehensive tunnel measurement system which comprises a chassis truck, a sensor bracket, a sensor, a sensor synchronizing and signal processing device, a data acquiring and processing device as well as a power supply device, wherein the sensor bracket is mounted on the chassis truck through a horizontal rotating shaft, and a plurality of area array cameras, LED lamps and thermal infrared imagers are mounted on the sensor bracket respectively; the area array cameras acquire image data of the section of a tunnel; the thermal infrared imagers acquire the temperature information of the inner wall of the tunnel; the synchronizing and signal processing device provides synchronous signals for the thermal infrared imagers and the area array cameras; the data acquiring and processing device acquires signals of the thermal infrared imagers and the area array cameras. The rapid and comprehensive tunnel measurement system can acquire data of various tunnel defects such as lining cracks, lining water leakage, section deformation, a disengaging defect and the like simultaneously and rapidly, the detection efficiency and the detection accuracy are improved greatly, manual intervention is not required in a detection process, and the safety is good when the system is used for detecting the lining water leakage and disengaging defect of the tunnel.

Description

technical field [0001] The invention belongs to the field of highway tunnel detection technology, and in particular relates to a tunnel rapid comprehensive measurement system for detecting indicators such as tunnel lining cracks, lining water leakage, and tunnel section geometric deformation. Background technique [0002] At present, the daily inspection work of operating tunnels is mostly inseparable from manual work. For example, the detection of tunnel lining cracks is identified by human eyes, then measured with a ruler, the camera takes pictures to record the crack characteristics, and the crack position information is manually recorded. For the inspection of lining cracks above the arch waist and the vault, scaffolding or high-altitude lifting platform trucks are required, so that inspectors can get close to the inner wall of the tunnel, use flashlights to illuminate, and visually inspect the defects of the arch waist and vault. The detection accuracy of lining cracks...
