This invention discloses an integrated sand and gravel sorting and cleaning machine for civil engineering, including an outer casing. In this invention, a vibrator is fixedly connected to the bottom end of the outer casing, and a motor is fixedly connected to the bottom end of the inner wall of the outer casing. A hollow shaft extends from the upper end of the motor, and two sets of hollow rotating rods are fixedly connected to the cylindrical outer surface of the hollow shaft, with the hollow shaft communicating with the hollow rotating rods. Each set of hollow rotating rods has brush bristles at its lower end. The motor drives the hollow rotating rods to rotate via the hollow shaft.

Simultaneously, when the regulating valve is opened, water is sprayed through the nozzles to clean the coarse and fine filter screens. The regulating valve can also be opened slightly, and the small water flow from the nozzles can further clean the sand and gravel, preventing dust from splashing during sand screening.
