[0002] Bridge piers are the core load-bearing components of a bridge, directly affecting its overall stability and safety. During bridge operation, piers are susceptible to collisions with ships, vehicles, and other objects, leading to pier damage and even serious accidents such as bridge collapse.

[0003] Existing bridge pier anti-collision structures mostly use single buffer materials or rigid protective devices, which have many shortcomings: single buffer materials have limited energy absorption effects and are difficult to cope with high-intensity impacts; although rigid protective devices can resist impacts, they easily transfer the impact force directly to the pier, causing damage to the pier; some anti-collision structures are integral designs, which are inconvenient to disassemble and assemble, and have high maintenance and replacement costs; and they lack effective guiding mechanisms, which cannot guide the impacting object away from the pier, and the impact force is concentrated on a local area of ​​the pier, resulting in poor protection.

[0004] Therefore, there is an urgent need for a bridge pier anti-collision buffer structure with good buffering and energy absorption effect, comprehensive protection, and convenient assembly and disassembly, in order to solve the problems existing in the current technology. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7 This utility model provides a technical solution: a bridge pier anti-collision buffer structure, including a buffer component 2, an elastic support component 3, and a guide component 4; the buffer component 2 is sleeved on the outside of the bridge pier 1 and is a multi-layer composite structure, which includes an elastic pad layer, an energy-absorbing layer, and a protective outer layer from the inside to the outside; the elastic support component 3 is evenly distributed along the circumference of the bridge pier 1, one end of the elastic support component 3 is connected to the inner side of the buffer component 2, and the other end is connected to the outer wall of the bridge pier 1; the guide component 4 is fixed to the outside of the buffer component 2.

[0022] Furthermore, the elastic pad is made of rubber material, and the inner side of the elastic pad has anti-slip texture, which can enhance the fit between the elastic support component 3 and the support seat 32, prevent the buffer component 2 from sliding, and at the same time play a preliminary buffering role.

[0023] Furthermore, the energy-absorbing layer is a honeycomb aluminum structure or a foamed concrete structure, with a thickness of 5-15cm. Honeycomb aluminum and foamed concrete have excellent energy absorption performance, which can effectively absorb impact energy and reduce the impact force transmitted to the pier.

[0024] Furthermore, the protective outer layer is made of high-strength polyethylene board, and the outer side of the protective outer layer is coated with a wear-resistant coating. The high-strength polyethylene board has high strength and good wear resistance, which can protect the internal buffer structure and extend its service life.

[0025] Furthermore, the elastic support component 3 includes a pier connector 31, a support base 32, and a spring 33. The support base 32 is fixed to the inner side of the buffer component 2. One end of the spring 33 is fixedly connected to the support base 32, and the other end is fixedly connected to the pier connector 31. The spring 33 is evenly distributed between the pier connector 31 and the support base 32. The pier connector 31 is connected to the outer side of the bridge pier 1. The spring 33 can further buffer the impact force and can return to its original shape after the impact, ensuring the reusability of the structure.

[0026] Furthermore, the pier connector 31 and the support base 32 are semi-circular structures. A rubber pad is adhered to the inner side of the pier connector 31, and the inner side of the pier connector 31 is connected to the outer side of the bridge pier 1 through the rubber pad, ensuring the stability of the connection between the pier connector 31 and the pier connector 32, and strengthening the overall structural stability.

[0027] Furthermore, the edge of the pier connector 31 is provided with a first mating edge 34. The first mating edge 34 of the two pier connectors 31 is fixed on the outside of the bridge pier 1 by bolts 5 and nuts, which also facilitates disassembly from the pier connector 31. The edge of the support seat 32 is provided with a second mating edge 35, and the second mating edge 35 of the two support seats 32 is also fixed to the buffer assembly 2 by bolts 5 and nuts, forming a stable ring structure on the outside of the bridge pier 1, ensuring the stable working state of the buffer assembly 2 on the support seat 32, and also facilitating the disassembly and assembly of the overall structure.

[0028] Furthermore, the guide component 4 is roller-shaped, with multiple components arranged vertically at equal intervals on the outside of the buffer component 2. This guides the impacting object to roll along the guide component 4, deviating from the bridge pier 1 and preventing the impact force from being concentrated on a localized area of ​​the bridge pier 1. The outer side of the guide component 4 is provided with a wear-resistant coating to improve its wear resistance and extend its service life.

[0029] Working principle: When using this anti-collision buffer structure, it is first necessary to install it on the bridge pier 1. Select a suitable height position on the bridge pier 1, and connect the two elastic support components 3 to the outside of the bridge pier 1. The first connecting edge 34 on the pier connector 31 is fixed with bolts and nuts. Under the action of the inner rubber pad, a stable connection with the bridge pier 1 is ensured. Then, the two buffer components 2 are installed on the outside of the support base 32, and the buffer components 2 are fixed to the second connecting edge 35 on the support base 32 with bolts 5 and nuts. This forms a stable ring structure around the bridge pier 1.

[0030] When an impacting object strikes the anti-collision buffer structure, it first contacts the guide component 4. The roller structure of the guide component 4 guides the impacting object to roll along its surface, changing the impact direction and preventing the impact force from being concentrated on a local area of ​​the bridge pier 1. Subsequently, the impact force is transmitted to the protective outer layer of the buffer component 2, which resists the impact and disperses the impact force. Then, the energy-absorbing layer deforms, absorbing a large amount of impact energy, achieving primary buffering. The elastic pad layer further buffers the remaining impact force, while the spring 33 of the elastic support component 3 is compressed, absorbing some energy and generating a rebound force, achieving secondary buffering. Through multi-stage buffering, energy absorption, and guiding effects, the damage to the bridge pier 1 caused by the impact force is significantly reduced.

[0031] The anti-collision buffer structure of this embodiment can effectively resist the damage to the bridge pier 1 caused by impacting objects through multi-level buffering energy absorption and guiding effects. It is also easy to assemble and disassemble, has low maintenance costs, and is suitable for the protection of various types of bridge piers.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
