The invention discloses a bridge pier anti-collision and anti-scouring device. The bridge pier anti-collision and anti-scouring device comprises a bridge pier body (1), multiple fixing piles (2), a cage frame (3) and an elastic plate (4), wherein the multiple fixing piles (2) surround the outer side of the bridge pier body (1); the fixing piles (2) are provided with flow blocking pieces (21); the steel cage frame (3) is fixed to the fixing piles (2) which are arranged at a water facing side of the bridge pier body (1); the cage frame (3) is filled with a first anti-collision body formed by irregular riprap; the elastic plate (4) is fixed to the fixing piles (2) arranged at a water backing side of the bridge pier body (1), so that a second anti-collision body is formed; water inlet holes are formed in the elastic plate(4). According to the bridge pier anti-collision and anti-scouring device disclosed by the invention, a scouring action on a bridge pier by water flow can be avoided, a collision action on the bridge pier by a collision body in water can also be avoided, the structure is simple, the cost is low, and the bridge pier anti-collision and anti-scouring device not only is suitable for the protection of newly-constructed bridge pier, but also is suitable for complementary protection of a constructed bridge pier.
