Abstract

The utility model discloses a muck scattering prevention device for an open cut subway station. The device comprises a concrete support, the two opposite sides of the upper portion of the concrete support are each provided with a steel angle, the steel angles are clamped to the upper edge of the concrete support, the outer sides of the two steel angles are correspondingly and fixedly connected with a plurality of vertical square steel pipes which are vertically arranged at intervals in the length direction of the steel angles, the length of each vertical square steel pipe ranges from 500 mm to 1000 mm, and the length of each vertical square steel pipe ranges from 500 mm to 1000 mm. The upper portions of the two pieces of angle steel are fixedly connected through a plurality of transverse square steel pipes arranged at intervals in the length direction of the angle steel, the transverse square steel pipes and the vertical square steel pipes are arranged correspondingly, and the upper ends of the two corresponding vertical square steel pipes on the two sides are each fixedly connected with an inclined supporting steel pipe. The upper ends of the two diagonal bracing steel pipes are fixedly connected and form tripods with the transverse square steel pipes, protective steel plates are laid on the outer sides of the diagonal bracing steel pipes on the two sides respectively and fixedly connected with the diagonal bracing steel pipes through dovetail screw bolts, and the tops of the tripods at the two ends are each fixedly provided with a hanging ring.
