Problems solved by technology

[0003] At present, the detection of cracks and water leakage in highway tunnels and subway tunnels in my country is mainly carried out by manual on-site records and disease marks. Finally, the workers draw the expansion diagram of the disease on the tunnel vault, and the traffic roads need to be closed during the detection. , the efficiency is low, this kind of detection method requires a lot of manpower and material resources, and the degree of danger is high. For the detection of tunnel vaults, special lifting equipment is required. The detection results are highly subjective, and different detection personnel will get different results. The safety evaluation of lining structure is mostly qualitative description
Foreign research institutes have developed different types of tunnel defect detection vehicles, but the monitoring indicators are single and the accuracy is low, and the detection of tunnel defects has high requirements for light. greater impact

Abstract

The invention discloses an automatic detection system device for apparent diseases of a highway tunnel and a subway tunnel. The device comprises a carrier vehicle provided with a power system, a positioning system and an identification system, an image acquisition system, and a lighting system. The power system drives the carrier vehicle to move forward; the positioning system acquires and recordsdisease location information of the tunnel lining; and the identification system recognizes a tunnel lining crack picture and calculates the opening and length of a crack. The image acquisition system collects apparent image data of the tunnel lining; and the lighting system covers the tunnel lining surface by light and eliminates a shadow caused by the uneven surface of the tunnel lining. Therefore, the simultaneous detection of the tunnel lining crack and the leakage water diseases is realized; and the detection equipment has characteristics of high monitoring efficiency, less lighting shadows, high detection accuracy, non-contact mode and the like.

Description

technical field [0001] The invention relates to the technical field of tunnel apparent disease detection, in particular to an automatic detection system device for road tunnel and subway tunnel apparent disease. Background technique [0002] In recent years, as the country has increased investment in infrastructure facilities, my country's transportation construction has achieved rapid development, and the construction of highway tunnels, especially long tunnels, has also achieved rapid development. At present, my country and become the world's largest tunnel project The largest, most complex, and fastest-growing countries. Tunnels are semi-hidden projects built in underground rock-soil media. Tunnels built in different periods and under different technical conditions have been operated for many years, and many diseases have appeared. Common tunnel diseases include: deformation encroachment, cracks, water leakage , Wrong platform, falling blocks, collapse, basement turbulenc...
