Abstract

The invention relates to airport runway crack detection and maintenance equipment. According to the airport runway crack detection and maintenance equipment, problems of low detection efficiency and low automation level of an existing airport runway crack detection device are effectively solved. The technical scheme for solving the problems is that a crack real-time monitoring device is arranged on a trailer; monitored data are transmitted to a micro-controller in real time; the micro-controller controls a grooving device to groove a rack according to the monitored crack data information; while the grooving device grooves the crack, protective plates are arranged on the trailer; during grooving, the two protective plates are closed to protect the crack detection device arranged on the trailer (damages of crushed stones and sand particles on the crack detection device during grooving can be avoided); while the grooving device grooves the crack, water in a water tank arranged on the trailer is sprayed to the grooving position through water spraying holes formed in the bottom walls of the protective plates; and therefore, larger dusts can be avoided during grooving.

Description

technical field

[0001] The invention relates to the technical field of airport runway surface detection, in particular to an airport runway crack detection and maintenance equipment. Background technique

[0002] In recent years, China's civil aviation industry has developed rapidly, and the total turnover of air transport has ranked second in the world. However, with the rapid growth of air traffic volume and the proportion of large-scale wide-body technology, some early-built airport runways may be in places with large temperature differences. The airport runway built in the area has serious damage to the pavement structure. It is more common that there are many cracks on the runway pavement, and these cracks are usually vertical (due to the long construction time, such cracks are mostly caused by the subsidence of the roadbed and base) or transverse cracks (Because the temperature difference changes greatly throughout the year, such cracks are mostly caused by the shrinka...
