Bridge pier steel jacket box anti-collision structure

The invention discloses a bridge pier steel jacket box anti-collision structure. The bridge pier steel jacket box anti-collision structure comprises cylindrical anti-collision steel jacket boxes arranged on a bridge pier, at least two pier columns are arranged on the bridge pier, each pier column is sleeved with one anti-collision steel jacket box, the outer walls of every two adjacent anti-collision steel jacket boxes are connected in a tangent mode, each anti-collision steel jacket box comprises an inner steel coaming and an outer steel coaming. A plurality of FRP roller structures annularly arranged and distributed along the peripheral face of the pier column are arranged between the inner steel coaming and the pier column, and the outer steel coaming and the inner steel coaming are connected through a plurality of deformable energy dissipation elastic pieces. According to the bridge pier steel jacket box anti-collision structure, when the anti-collision steel jacket box is impacted by a ship, deformation
