TECHNICAL FIELD

[0001] The utility model relates to bridge pier protection device technical field, concretely relates to a bridge pier protection sleeve. BACKGROUND

[0002] In the field of bridge engineering, bridge piers, as the key part of supporting bridge structure, are exposed to the natural environment for a long time and face many severe challenges. The continuous erosion of water flow will gradually erode the soil around the bridge pier foundation, leading to the decline of the foundation stability; high-speed ships may collide with the bridge pier due to loss of control or improper operation, causing direct structural damage to the bridge pier; in addition, chemical substances in water and corrosive components in the atmosphere will erode the surface of the bridge pier, weakening the strength of the bridge pier over time.

[0003] Traditional bridge pier protection measures have obvious limitations. Some simple protection methods, such as applying ordinary protective paint only on the surface of the bridge pier, can resist slight corrosion to some extent, but they are almost ineffective in providing protection against water erosion and strong impact. Existing partial protection structures are often complex to install, requiring a large amount of manpower, material resources, and time cost, and have defects in sealing performance, which cannot completely prevent the intrusion of water and impurities, leaving the internal reinforcement of the bridge pier still at risk of corrosion, thereby affecting the overall durability and safety of the bridge pier. In addition, some protection devices lack consideration of water flow dynamics and cannot effectively change the water flow pattern to reduce the impact force and erosion of water flow on the bridge pier foundation. Therefore, it is a technical problem to be solved to develop a new type of bridge pier protection device that can comprehensively, efficiently, and conveniently protect the bridge pier while having good durability, sealing performance, and water flow guiding function.
