[0002] With the development of my country's highway bridge industry, the research on the mechanism of bridge cracks has become more in-depth. The types and causes of cracks in concrete bridges are often due to the following factors: concrete shrinkage cracks, temperature cracks, bending cracks caused by load, shear cracks, disconnection cracks, cracks caused by steel corrosion, cracks caused by uneven foundation settlement, cracks caused by frost heave, cracks caused by construction quality, etc.

[0003] The following methods are often used to repair cracks: surface sealing repair method, deep groove repair method and surface spraying method, etc. The inspection of crack treatment effect includes repair material test, core sampling test, water pressure test, air pressure test, etc. In order to carry out crack repair work, it is usually necessary to clean the existing state or the state after chiseling and expansion. The traditional process uses air blowing and manual cleaning. Air blowing uses high-pressure air jets to blow away the garbage at the crack position. This practice often causes dust and garbage dispersion on the working surface, which has high requirements on equipment performance, is not conducive to benefit control, and cannot meet the environmental protection requirements of the construction site; manual cleaning is inefficient and has high labor costs. It cannot achieve a uniform effect for crack cleaning, resulting in a great reduction in construction efficiency. Summary of the invention
