Description
technical field [0001] The invention belongs to the technical field of bridge crack detection, and in particular relates to a bridge crack detection device and a detection method. Background technique [0002] Nowadays, with the continuous development of bridge technology, not only the total mileage of bridges is also increasing year by year, but also the length of bridges is also lengthening, and bridges are also being built in places with harsh environments. The bridge is the throat of traffic, coupled with the rapid increase of existing traffic volume, the increase of heavy vehicles, and the overspeed and overweight transportation of vehicles, it is difficult for the bearing capacity of the bridge to adapt to the rapid increase of traffic load, and the bridge is in an overloaded state for a long time Cracks are prone to appear in underground work; in addition, the geological conditions, topographical conditions, climatic conditions and the influence of various factors in ...
