Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge pier anti-collision, in particular to a bridge pier anti-collision hoop buckle structure and a use method thereof. BACKGROUND

[0002] With the increasing frequency of exchanges between regions and the continuous improvement of road traffic facilities, a large number of sea-crossing and river-crossing bridges have been built in China. Many bridges are built on navigable waterways, and in recent years, ship collisions with bridge piers have occurred from time to time, and some have even caused major safety accidents.

[0003] The bridge pier is the basic structure that supports the bridge, usually made of stone or reinforced concrete. Its role is to bear the weight of the bridge and withstand the pressure of the bridge deck, and its role is very important. Therefore, when building a bridge pier, not only its stability, durability and load-bearing capacity need to be considered to ensure the safety and durability of the bridge body. Anti-collision measures should also be taken to improve the anti-collision ability of the bridge pier to ensure the safety and durability of the bridge pier after being hit by a ship.

[0004] After searching, the existing patent (publication number: CN 209603017 U) discloses a bridge pier anti-collision structure, which includes an energy dissipation layer wrapped on the outside of the bridge pier and an anti-collision layer wrapped on the outside of the energy dissipation layer. The energy dissipation layer is filled with light aggregate concrete, and the anti-collision layer includes an inner wall, an outer wall, and a filling structure arranged between the inner wall and the outer wall. The filling structure includes a plurality of parallel arranged ridge skeletons and energy absorbing materials filled in the gaps of the ridge skeletons. The bridge pier anti-collision structure provided by the technical solution can effectively reduce the damage to both parties when a vehicle or a ship collides with the bridge pier.

[0005] However, in the implementation of the related technology, the above-mentioned problems are found: the above-mentioned anti-collision structure uses a fixed energy dissipation layer and an anti-collision layer to protect the bridge pier from collision, which can only physically protect the lower half of the bridge pier. Its anti-collision range and anti-collision performance are poor, and after being hit by a ship, it cannot effectively and reasonably transmit the impact pressure to the bridge pier, and cannot form a counter thrust to do work on the ship, resulting in serious damage to both the bridge pier and the ship after being hit. In addition, the above-mentioned structure has high requirements for the environment of the bridge pier, and it is not only difficult and costly to construct in the seabed, but also inconvenient to maintain the bridge pier in the later period, so its application range is small and its practicality is not strong.
