Environment-friendly construction equipment for civil engineering

The invention discloses environment-friendly construction equipment for civil engineering, and relates to the technical field of civil engineering equipment. An air inlet pipe is arranged on one side of the box body, an air outlet pipe is arranged on the other side of the box body, an impeller is rotationally installed in the air inlet pipe, a connecting shaft is fixedly installed on the impeller, a first gear is fixedly installed on the connecting shaft, the first gear is in transmission connection with a second gear through a gear belt, and the second gear is fixedly installed on a rotating shaft. The rotating shaft is fixedly provided with a cam, the rotating shaft is rotatably mounted in the water tank, and one end of a first filter screen is rotatably mounted above the water tank. When a cam rotates, the bottom of the first filter screen can be continuously collided, so that the first filter screen is vibrated, filtered dust slides in the inclined direction of the first filter screen and then slides out
