Abstract: The present invention relates to the technological field of civil engineering, particularly to a dust reduction device for building engineering. The device includes a water tank with a controller and a booster pump, a driving mechanism enabling the device to cross obstacles, an adjustable spray mechanism with a mist intercepting mechanism, and an environment detection mechanism. The dust reduction device comprising the above components can move along the enclosure barrier to a target position for spraying according to real time requirements. The adjustable spray mechanism is configured in such a way that, when the wind force is between the specified minimum value and maximum value, and the wind direction is opposite to the spray direction, the mist intercepting mechanism is activated to avoid water mist blowing outside the construction site by wind and affecting the normal passage of pedestrians.
