Screening system for shield muck treatment

The invention belongs to the technical field of shield muck treatment, particularly relates to a screening system for shield muck treatment, and solves the problems that a screening device is low in screening efficiency, poor in effect and high in sand and stone mud ratio in the prior art. The screening system comprises a vibrating screen (1) and a mounting frame (2), wherein the vibrating screen (1) is fixedly connected to the mounting frame (2); a feeding machine (3) is arranged at the feeding end of the vibrating screen (1); the vibrating screen (1) is provided with a high-pressure spraying pipeline (4) in a matched mode; and the high-pressure spraying pipeline (4) flushes each layer of screen. According to the screening system, the feeding machine is used for feeding materials to the vibrating screen, so that the amount of shield muck entering the vibrating screen is uniform, the muck is loose, the screening efficiency and the screening effect can be improved, and the high-pressure spraying pipeline flush
