Description

TECHNICAL FIELD

[0001] The utility model relates to bridge protection technical field, concretely is a novel self -floating bridge protection device. BACKGROUND

[0002] As is known to all, with the continuous expansion of global transportation network, the safety of bridges, which serve as important transportation hubs connecting different regions, is of vital importance. Bridge structures not only need to bear daily traffic loads, but also face challenges from natural environments (such as floods, storms) and human factors (such as ship impacts, floating object impacts). Especially for bridges located on rivers, lakes or oceans, they are more likely to be accidentally impacted by water-borne vehicles and floating objects. These external impacts may cause damage to bridge structures and even lead to serious safety accidents.

[0003] Traditional fender piers are usually fixed around the bridge piers and cannot adapt to changes in water level. Although the existing rubber buffers can absorb impact force to a certain extent, their buffering effect is limited, especially when facing larger impacts, which may easily cause damage to the buffers themselves or the bridge structure. Moreover, traditional protective facilities are usually designed as a whole, so once a part is damaged, the entire facility needs to be replaced, increasing maintenance costs and time. SUMMARY
