Fabricated anti-collision facility for water area pier

The invention provides a fabricated anti-collision facility for a water area pier. The fabricated anti-collision facility comprises a plurality of anti-collision buoyancy tanks which are sequentially connected around the pier, each anti-collision buoyancy tank comprises an anti-collision buoyancy tank body and tank body connecting parts, each anti-collision buoyancy tank body is of a reinforced concrete structure, two vertically-distributed tank body connecting parts are arranged at the two connecting ends of the anti-collision buoyancy tank body, and an internal energy consumption device used for absorbing and consuming impact energy generated when the anti-collision buoyancy tank body is impacted is arranged in the anti-collision buoyancy tank. Gaps in the anti-collision buoyancy tank are filled with macromolecule damping energy dissipation materials, and when the anti-collision buoyancy tank body is damaged, buoyancy borne by the macromolecule damping energy dissipation materials filled in the anti-collisi
