Description

Detachable steel buffer bracket for preventing ship collision of bridge pier Technical Field The utility model relates to the technical field of anti-collision buffer supports, in particular to a detachable steel buffer support for preventing a bridge pier from being bumped by a ship. Background With the rapid development of the construction of the traffic infrastructure in China, the number of bridges crossing rivers, lakes and offshore channels is increased year by year, in the navigation water, bridge pier columns often face the risk of ship collision, particularly, the occurrence of accidents caused by the collision of the ships with the bridge pier columns under severe weather such as strong wind, heavy rain, dense fog and the like or improper navigation operation, and the collision can possibly cause damage to bridge structures and serious traffic safety accidents, thereby bringing great threat to the life and property safety of people. At present, the protection measure against ship collision to bridge pier stud mainly includes setting up crashproof fender, installation concrete anticollision body and adopts steel buffer stop etc. wherein, traditional crashproof structure is mostly fixed design, although can absorb the impact energy to a certain extent, but ubiquitous buffer performance is limited, the installation is maintained inconvenience, reuse rate low grade problem, in addition, some current buffer stop easily appear structural deformation or material fatigue damage after receiving the striking, lead to its damping performance to descend, influence follow-up result of use and security.
