Intelligent highway engineering maintenance operation device

The invention discloses an intelligent highway engineering maintenance operation device which comprises a traveling vehicle body and a water tank body arranged outside the traveling vehicle body, a laying mechanism is arranged outside the water tank body, the laying mechanism comprises a telescopic roll shaft, a water sprinkling mechanism is arranged outside the water tank body, and the water sprinkling mechanism comprises a horizontal connecting pipe. A variable-frequency constant-pressure water pump is installed outside the horizontal connecting pipe, a plurality of corrugated connecting pipes fixedly communicate with the outside of the horizontal connecting pipe, duckbilled spray heads are installed at the ends, away from the horizontal connecting pipe, of the corrugated connecting pipes, and telescopic control assemblies are arranged outside the duckbilled spray heads. The distance between the two vertical sliding rails A is changed by starting the horizontal electric-hydraulic push rod, the distance betw
