Description

Technical Field

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. After the bridge is built, it needs to be protected by bridge protection devices. Bridge protection devices are installed on the bridge. 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, and climbing over the bridge, as well as beautifying the bridge building.

[0003] In the prior art, when a vehicle deviates during driving and causes a strong collision with a bridge protection device, the protection device is prone to deformation and damage due to the inability to buffer the impact force caused by the collision. The deformation and damage cause the device to collapse easily, which in turn makes the vehicle prone to falling. Existing protection devices generally install guardrails when building bridges, which is cumbersome to operate and inconvenient for subsequent maintenance and replacement. Utility Model Content
