[0003] On the one hand, the traditional bridge anti -collision device buffer energy absorption effect is poor. Common simple structure anti -collision facilities, such as part of the device only relying on single material or basic structure, when facing high-speed vehicle impact, cannot effectively disperse and absorb huge impact force. When the vehicle collides with the bridge, the strong force is directly transmitted to the bridge body, which can easily cause the bridge structure damage, such as pier cracking, bridge deformation, etc., seriously affecting the safety and service life of the bridge, increasing the maintenance cost and safety hazard.

[0004] On the other hand, the installation and connection mode of the traditional anti -collision device is not reasonable. Part of the device installation process is complex, which needs to consume a lot of manpower, material resources and time, and the stability is insufficient after installation. In the long-term use process, affected by external environmental factors (such as temperature change, rain and wind erosion) and vehicle impact, the connecting part is easy to loosen, which causes the anti -collision device to fail to play a normal role and cannot continuously provide reliable protection for the bridge.

[0005] In addition, the traditional anti -collision device has poor durability. Some anti -collision facilities made of ordinary materials are easy to age and corrode under the action of natural environment such as wind and sun, rain erosion. Moreover, after being hit for many times, the structural performance will decrease significantly, which is difficult to maintain effective protection for the bridge, and frequent replacement not only increases the economic cost, but also may affect the normal passage of the bridge.

[0009] A plurality of the aluminum foam columns are arranged in the buffer cavity, and the top and bottom of each of the aluminum foam columns are fixedly connected to the surfaces of the upper and lower aluminum plate layers, respectively.

[0010] The aluminum foam column is surrounded by an aluminum skin to form a containing cavity, and the containing cavity is filled with aluminum foam to form a hollow structure inside the aluminum foam column, which extends along the length direction of the aluminum foam column and has a rectangular cross-section in the horizontal direction.

[0023] In addition, the rubber ring layer 13 also has the functions of sealing and shock absorption, can fill the gaps between the aluminium plates, prevent dust, moisture, etc. from entering the buffer cavity 14 and affecting the performance of the internal components, and further reduce the vibration caused by impact, improve the stability and reliability of the entire device, work cooperatively with the aluminium plate layer 11, foamed aluminium column 21, etc. to improve the protection effect of the bridge anti-collision device.
