Dustproof device for tunnel construction

The utility model discloses a dustproof device for tunnel construction, which comprises a base, a damping structure, an atomizing nozzle and a support, the top end of the base is fixedly connected with the damping structure, the top end of the damping structure is fixedly connected with a main frame, one side of the main frame is fixedly connected with a control box, and one side of the control box is fixedly connected with a switch. The top end of the main frame is fixedly connected with a water outlet pipe, the top end of the water outlet pipe is fixedly connected with an atomizing nozzle, awater suction pump is fixedly connected to the middle of the water outlet pipe, and a water inlet pipe is fixedly connected to the interior of the main frame. When an object is maintained, due to thefact that the interior of a construction tunnel is dark, the internal visibility is low, the construction difficulty is increased, the visibility during maintenance can be increased through turning on an illuminating lamp at
