If you want to know about dry goods sharing: bridge anti-collision steel guardrail anti-collision performance requirements, it is recommended that you take a look at the following article in order to have a more in-depth understanding of it.
Bridge crash steel guardrails are important facilities designed to protect the bridge and its surrounding people and vehicles from collision injuries. The following is a brief introduction to its anti-collision performance requirements, material, type, grade and characteristics.
1. Anti-collision performance requirements:
High Strength: Able to withstand the force of a vehicle crash to protect the vehicle and its occupants from injury.
Anti-corrosion: long-term exposure to oxygen, moisture, chemicals, etc. in the atmosphere, not corroded, maintain a good service life.
Rust resistance: Even in a humid environment, it can effectively prevent the corrosion of the bridge anti-collision steel guardrail.
Serviceability: Easy to repair and replace, able to quickly restore function.
2.Material:
Steel: generally made of galvanized steel or hot-dip galvanized steel, which has good anti-corrosion and anti-rust properties.
Stainless steel: Commonly used stainless steel materials are 304 and 316, which are well resistant to corrosion.
3.Type:
Metal guardrail: It is usually composed of several metal columns and beams, which can withstand large impact forces.
Cable guardrail: A guardrail consisting of multiple steel cables and columns, which mainly uses tension to absorb impact forces.
Concrete guardrail: The guardrail is made of concrete material, which has high strength and stability.
4.Grade:
The traffic volume of different regions and bridges is different, and it is necessary to select the corresponding collision avoidance level, such as identification level, vehicle level, etc. The higher the grade, the greater the impact resistance required.
5.Features:
Aesthetic and generous: According to the design style and environmental requirements of the bridge, you can choose different shapes and colors of bridge anti-collision steel guardrails to make them harmonious and unified with the surrounding environment.
Easy installation: Modular structure, easy to install and disassemble, reduce labor and time costs.
Low maintenance costs: Stainless steel and galvanized steel are corrosion-resistant, requiring less maintenance and reducing maintenance costs.
By meeting the requirements of anti-collision performance, the bridge anti-collision steel guardrail selects the appropriate material, type and grade, has a good anti-collision function, and shows a series of characteristics. This is an important facility to ensure the safety of the bridge.
