Anti-collision structure of road bridge

The invention discloses an anti-collision structure of a road bridge. Stand columns are included, and there are several groups of stand columns. The two stand columns are arranged in each group; the two stand columns in each group are inserted into support cylinders; the two supporting cylinders are arranged at a lower end of each stand column; a transverse supporting rod is connected between thesupporting cylinders at the bottoms of the stand columns; and a plurality of connecting ribs are connected between the transverse supporting rods at the bottoms of the multiple groups of stand columns, there are a plurality of the connecting ribs, the connecting ribs are symmetrically distributed relative to two sides of the transverse supporting rods, tie bars are arranged between the connectingribs on the two sides of the transverse supporting rods, the tie bars are an ''X''-shaped cross distribution structure, and a strip-shaped notch is formed in one side of each supporting cylinder. According to the anti-collisio
