Corrugated guardrails are commonly used safety facilities on both sides of the highway, mainly by reflecting the impact force of vehicles to reduce the severity of accidents. Corrugated guardrails can be divided into two types: two-wave and three-wave according to the different anti-collision performance. This article will detail the difference between two waves and three waves of corrugated guardrails.
1. Overview. The corrugated guardrail is a kind of protective fence made of corrugated steel, and its corrugated design can effectively disperse the impact force and reduce the degree of damage to the vehicle in the event of impact. Corrugated guardrails are usually installed on both sides of the highway or on the first divider, which is an important traffic safety facility.
2. Two-wave waveform guardrail.
The two-wave corrugated guardrail is a common form of guardrail, and its height is generally 800mm, the height is small, and the protection ability is relatively weak. The advantages of the two-wave corrugated guardrail are simple structure, low cost and easy installation, so it is widely used on some low-speed highways or rural roads.
3. Three-wave waveform guardrail.
Compared with the two waves, the height of the three-wave corrugated guardrail is higher, generally 1100mm, and the protection capacity is stronger. The advantage of the three-wave corrugated guardrail is that its structure is more stable and can better withstand high-speed impacts, so it is widely used in high-grade highways such as highways.
Fourth, the comparison of two-wave and three-wave waveform guardrails.
The two-wave and three-wave waveform guardrails are different in terms of structure, height, protection capabilities, and application scenarios. Specifically, the two-wave corrugated guardrail has a small height, simple structure, low cost, easy installation, and is suitable for scenarios such as low-speed highways or rural roadsThe three-wave corrugated guardrail has a higher height, stronger protection ability and more stable structure, which is suitable for high-grade highways such as highways.
5. Choose the right corrugated guardrail.
When choosing a corrugated guardrail, it is necessary to consider factors such as road grade, traffic flow, and design speed. If the road grade is low, the traffic flow is small, and the design speed is low, you can choose two waves of corrugated guardrails;If the road grade is high, the traffic volume is large, and the design speed is high, it is necessary to choose a three-wave corrugated guardrail or a higher level of collision avoidance equipment.
VI. Conclusion. Corrugated guardrail is an important part of highway safety facilities and plays an important role in ensuring driving safety. When choosing a corrugated guardrail, it is necessary to consider the actual situation comprehensively and choose the appropriate form and specification. At the same time, it is also necessary to strengthen the maintenance and maintenance of the corrugated guardrail, and carry out regular inspection and repair to ensure its normal operation and provide a strong guarantee for highway safety.
