Abstract

A tunnel full-section lining crack intelligent acquisition and detection system belongs to the technical field of tunnel lining crack intelligent acquisition and detection, and has the following specific scheme: the tunnel full-section lining crack intelligent acquisition and detection system comprises a mobile device and a detection device, the detection device is mounted on the mobile device, the mobile device comprises an arch-shaped frame, trundles and trundle driving devices, the trundle driving devices are installed on the trundles, the trundles are arranged at the bottoms of the two sides of the arch-shaped frame, and the detection device comprises a plurality of image acquisition units, a storage unit, an image processor and a control module. The plurality of image acquisition units are arranged in an arch shape, are uniformly distributed on the outer surface of the arch-shaped frame and are electrically connected with the storage unit, the storage unit is electrically connected with the image processor, and the image processor and the trundle driving devices are electrically connected with the control module. Full-section detection can be carried out on the tunnel at any time, and the problem that transportation is affected due to traffic blocking in the detection process is solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent collection and detection of tunnel lining cracks, and in particular relates to an intelligent collection and detection system of tunnel lining cracks. Background technique [0002] After the tunnel is built, because the tunnel lining is subjected to complex ground stress and confined water, cracks and water leakage will appear in the tunnel lining structure, and even icing will occur in the alpine region, which will bring extreme difficulties to the later operation of the tunnel. Great hazard, affecting the service life of the tunnel. [0003] How to accurately and quickly detect the cracks in the tunnel lining has been a concern in the industry. The most primitive way is manual inspection, which is time-consuming and labor-intensive, cracks are missed, and the tunnel needs to be temporarily closed. Later, a vehicle-mounted tunnel crack detection system appeared. Although the detection rate ...
