Pier anti-collision device with relative height position capable of being adaptively adjusted

Abstract

The invention relates to a pier anti-collision device with the relative height position capable of being adjusted in a self-adaptive mode. The pier anti-collision device comprises an annular floating body and an energy dissipation assembly. The annular floating body sleeves the periphery of the pier in a clearance fit mode, and the relative height position of the annular floating body can be adaptively adjusted according to different water levels under the action of water buoyancy. The energy dissipation assembly is used for directly bearing impact force from a ship and is assembled with the annular floating body into a whole. The annular floating body has the capacity of absorbing residual impact energy conducted by the energy dissipation assembly. Therefore, on one hand, on the premise that the manufacturing cost and the construction difficulty are not obviously increased, all-directional protection of the pier is achieved, and it is guaranteed that the pier has the capacity of meeting accidental collision of ships from different directions; and on the other hand, impact energy from a ship is absorbed by the energy dissipation assembly and the annular floating body in sequence in a coordinated mode, so that the stress form of the pier anti-collision device is effectively optimized when the pier anti-collision device is collided, and it is ensured that the pier anti-collision device has the long service life.

Description

technical field [0001] The invention relates to the technical field of bridge pier protection, in particular to an anti-collision device for bridge piers whose relative height position can be adjusted adaptively. Background technique [0002] The bridge pier is the middle support structure in the bridge with two or more holes except the abutment connected with the embankment at both ends. With the large-scale application of waterway transportation, the number of ships in rivers is also increasing day by day, which will inevitably lead to an increase in the probability of piers being collided by ships. In this way, when the piers are damaged due to collisions, a lot of manpower and material resources need to be invested. It is reworked to ensure the application safety of the bridge. [0003] In the prior art, in addition to increasing the strength of the bridge pier, a ship collision prevention system is usually arranged on the bridge pier to reduce the hazard of collision. ...

AI Technical Summary

Problems solved by technology

If the traditional anti-collision method is adopted, it will inevitably increase the construction height of the artificial island and the pile group, and increase the protective length of the steel casing relative to the pier (that is, a substantial increase in the total design length of the steel casing), resulting in ship-proof The overall cost of the collision system remains high, and it also increases the total manufacturing cycle of the bridge to a certain extent
