Recently, many people are interested in taking you to understand the common types of bridge crash railings, in order to meet everyone's needs, let's talk about it, if you are interested, you can learn about it.
The common types of bridge crash railings mainly include:
1. Metal guardrail: Metal guardrail is one of the common types of bridge crash railings. It is usually made of steel and has high strength and impact resistance. The metal guardrail is simple and convenient to install, which can effectively protect the bridge and vehicles.
2.Concrete crash walls: Concrete crash walls are another commonly used type of bridge crash barrier. It usually consists of precast concrete blocks, which can be designed in different shapes and sizes as needed. Concrete crash walls are strong and durable, which can effectively absorb collision energy and protect bridges and vehicles.
3.Cable guardrail: The cable guardrail is composed of high-strength steel cables and support rods. It has flexibility and an ideal energy-absorbing property on the edge, which can reduce the impact force in the event of a collision. Cable guardrails can also adjust the height and spacing of support poles to accommodate different road and bridge shapes.
4.Plastic crash bars: Plastic crash bars are usually made of materials such as high-density polyethylene, which have good flexibility and impact resistance. It does not rust, corrode, and at the same time does not cause harm to vehicles and pedestrians. Plastic crash bars are often used for crash protection at bridge edges.
In addition to the common types mentioned above, there are some other types of bridge crash railings, such as wooden guardrails, glass guardrails, etc. Depending on the actual needs and environmental conditions, the appropriate type of crash barrier can be selected to protect the bridge and driving safety.
The main goal of bridge crash railings is to protect the bridge and driving safety. Different types of crash rails have different characteristics and scope of application, which can be selected according to the actual situation. When designing and installing crash barriers, it is necessary to consider the speed and collision force of the vehicle, as well as the curvature of the road, height difference and other factors to ensure the safety and effectiveness of the crash barriers. Regular maintenance and inspection is also an important part of ensuring the normal function of the crash barrier.
