Description

Technical Field

[0001] The utility model relates to the technical field of roads and bridges, and in particular to a road and bridge guardrail. Background Art

[0002] Bridge guardrails refer to guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going over the bridge. They have the function of preventing vehicles from breaking through, passing under, or climbing over the bridge, as well as beautifying the bridge structure.

[0003] For example, the Chinese patent application number CN202221390399.5 discloses a bridge guardrail. Specifically, the buffer assembly in this patent includes a rubber sleeve, which can be activated when a vehicle hits it, driving the connecting column to move inwardly toward the guardrail. During this movement, the movable rod is opened by the force, and at the same time, the interaction between the spring and the sliding rod effectively reduces the impact force on the guardrail. In addition, the friction rod will move toward the inside of the sliding hole, thereby increasing the friction and reducing the degree of damage to the guardrail. This not only reduces the damage to the guardrail, but also protects the vehicle that hits the guardrail to a certain extent.

[0004] However, although relevant technologies have made progress in improving protective performance and reducing impact damage, there are still certain deficiencies in anti-corrosion and rust removal, especially in the treatment of the interior of the guardrail, which may affect the long-term durability and overall safety performance of the guardrail.

[0005] In view of this, this application is hereby filed. Utility Model Content
