High-speed precision subway tunnel concrete lining crack detection equipment

Abstract

The invention discloses high-speed precision subway tunnel concrete lining crack detection equipment. The equipment comprises an image acquisition device, a shock-proof transportation device, a positioning device and a power supply control device. In this way, according to the high-speed precision subway tunnel concrete lining crack detection equipment, the image acquisition device is mounted on the shock-proof transportation device, a camera is mounted on a telescopic vertical frame, the camera performs image acquisition work while advancing along the tunnel direction, then an image signal acquired by the camera is converted into a digital signal which can be recognized and processed by an industrial personal computer through an image acquisition card, and finally, the digital image is processed to obtain a crack damage grade, safe operation of the tunnel is guaranteed. The equipment has the advantages of firm and stable overall structure, rapidity, high in precision, reliable detection and comprehensive and intelligent detection, and meanwhile has wide market prospects in application and popularization of tunnel disease detection.

Description

technical field [0001] The invention relates to the technical field of subway tunnel detection, in particular to a high-speed precision subway tunnel concrete lining crack detection device. Background technique [0002] At present, my country's social economy is growing rapidly, and the transportation is developing rapidly. Various railways, highways, tunnels, and subways are also being built on a large scale. Lining refers to the permanent construction of reinforced concrete and other materials along the periphery of the tunnel body in order to prevent the deformation or collapse of the surrounding rock. Permanent support structures are usually used in tunnel engineering and water conservancy channels, but in tunnel engineering construction, due to the temperature difference between the inside and outside of the concrete, the inconsistency of the humidity inside and outside the concrete, the reduction of the curing time after pouring, and the segmental pouring of concrete, et...
