Description

Municipal road crack length degree of depth integration detection device Technical Field The invention relates to the technical field of road crack measurement, in particular to an integrated detection device for the length and depth of a municipal road crack. Background In the long-term use process of municipal roads, the pavement is easily cracked, pits and other diseases due to the influence of factors such as vehicle load and natural environment erosion, and the accurate detection of critical dimensions such as the length, depth and the like of the diseases is a precondition for the establishment of a scientific repair scheme. In the prior art, the detection of the road cracks and pits is usually carried out in steps, wherein tools such as chalks, lime and the like are adopted to manually mark the boundaries of the diseases, particularly the irregular diseases are marked one by one after being divided into regular shapes, and then the length, the width and the depth are respectively measured through equipment such as a tape measure, a range finder and the like.
