The application relates to a group pile type bridge anti-ship collision device, which belongs to the field of bridge anti-ship collision devices. It includes structural piles and floating islands. The structural piles are arranged around the outer periphery of the bridge. The floating island is composed of multiple sections of floating boxes connected by connectors. The floating boxes are installed on the structural piles. There is a gap between the floating island and the bridge. There is a sealed air chamber to make the floating box float in the water. There are rollers on the structural piles. The rollers protrude from the surface of the floating box. The surface of the rollers is coated with lubricating glue. . In the present application, by arranging floating islands, structural piles and rollers, and by applying lubricating glue on the rollers, when the ship hits the floating island, it can be guided to slide toward the side wall of the floating island by contacting the rollers, so that the ship is not easy to stop instantaneously. If the impact force is too large, it also increases the impacted area of ​​the floating island, so as to better dissipate the energy of the ship and play a good anti-collision protection effect on the bridge.
