The utility model relates to a sand screening device for bridge construction. The sand screening device effectively solves the problems that sand screening efficiency is low, and secondary screening is needed. According to the technical scheme, the device comprises a fixed screen with the left high and the right low, identical supporting plates are fixed to the front end and the rear end of the screen correspondingly, sliding blocks are slidably installed on the supporting plates correspondingly and can slide back and forth along the supporting plates, a rectangular baffle is placed between the two sliding blocks, and the baffle is obliquely placed relative to the screen; the sliding block can drive the baffle to slide back and forth; the fine sand screening device is novel in conception, ingenious in structure and high in practicability, the baffle moves upwards along the screen, fine sand which cannot be screened off on the screen is collected and gathered again, then the fine sand is fully and repeatedly s
