[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 and 2 As shown, the present embodiment discloses a highway bridge anti-collision facility, including a base plate 2 fixed on the side wall of the bridge 1, a plurality of energy dissipation blocks 3 are arranged on the side of the base plate 2 away from the bridge 1, the energy dissipation blocks 3 are arranged in sequence along the length direction of the bridge 1, a plurality of elastic buffers 4 are arranged between the energy dissipation blocks 3 and the base plate 2, one end of the elastic buffer 4 is connected to the base plate 2, and the other end is connected to the energy dissipation blocks 3, the energy dissipation blocks 3 and the elastic buffers 4 absorb the impact force of the super-high vehicle at the same time.

[0020] The bottom plate 2 is arranged along the length direction of the bridge 1. The bottom plate 2 converts the impact force into a large area distributed load, which greatly reduces the force on the bridge. There are multiple energy dissipation blocks 3 arranged at intervals, and each energy dissipation block 3 is an independent individual. In this way, a local number or a single energy dissipation block 3 can be replaced separately, saving the cost of destruction.

[0021] In order to prevent the elastic buffer 4 from bending due to the weight of the energy dissipation block 3 , a suspension member 6 is provided above the energy dissipation block 3 , one end of the suspension member 6 is connected to the energy dissipation block 3 , and the other end is connected to the bottom plate 2 .

[0022] The energy dissipation block 3 is L-shaped, the vertical part of the energy dissipation block 3 is arranged parallel to the side wall of the bridge 1, and the horizontal part of the energy dissipation block 3 extends toward the side wall of the bridge 1. The horizontal part of the energy dissipation block 3 can protect the elastic buffer 4 to prevent the vehicle from directly contacting and damaging the elastic buffer 4 structure after passing over the energy dissipation block 3. Secondly, the horizontal part of the energy dissipation block 3 presses down the super-high part of the vehicle to a certain extent, absorbing energy itself while destroying the super-high part of the vehicle, reducing the risk of the super-high part of the vehicle directly hitting the bridge.

[0023] like Figure 3As shown, the structure of the energy dissipation block 3 includes a closed structure shell 301, and the shell 301 is filled with energy absorbing material 302. The shell 301 can be made of metal, and the energy absorbing material 302 can be polyurethane or fiber-vinyl reinforced material.

[0024] In this embodiment, the energy dissipation block 3 is provided with a wear plate 5 on the side surface facing away from the elastic buffer 4. The wear plate 5 first contacts the super-high vehicle to resist the vehicle collision. In the case of a minor collision, the wear plate 5 is intact and does not need to be replaced; or the wear plate 5 is damaged and the energy dissipation block 3 is intact, so only the wear plate 5 needs to be replaced. The wear plate 5 can be made of polytetrafluoroethylene.

[0025] In this embodiment, the elastic buffer 4 is a spring, and connecting seats are fixed at both ends of the spring. The connecting seats can be fixed to the metal base plate 2 and the shell 301 by pin riveting.

[0026] In this embodiment, the suspension member 6 is a steel wire rope. Both ends of the steel wire rope are connected to the lifting rings, and the lifting rings are fixed on the bottom plate 2 and the energy dissipation block 3.

[0027] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
