This utility model discloses a road marking pollution prevention device during construction, relating to the technical field of road construction equipment. It includes a fixed plate, with several electric push rods evenly arranged on the left outer wall of the fixed plate. A mounting shell is provided at the end of the telescopic arm of each electric push rod. A slider is slidably mounted inside the mounting shell, and a threaded rod is rotatably mounted inside the mounting shell, passing through and threadedly connected to the slider. A mounting frame is provided on the side wall of the slider, and a fixed shell is located at the bottom left side of the mounting frame. A groove is provided on the upper inner wall of the fixed shell, and two sliding plates are slidably mounted on the fixed shell. A protective plate is provided at the bottom of the sliding plates.
