Corrugated guardrails are widely used in highways, railways and other transportation fields, among which two-wave guardrails and three-waved guardrails are the two most common types. This article will make a detailed comparison and introduction of the differences between these two types of guardrails.
1. Appearance and structure.
The two corrugated guardrails are mainly composed of two corrugated beams, each of which is composed of two peaks and two troughs, and the whole presents a continuous wave shape. This kind of guardrail has a simple appearance, smooth lines, and a certain visual beauty.
The three-wave guardrail consists of three corrugated beams, each of which is also composed of two crests and two troughs. Compared with the two-wave guardrail, the three-wave guardrail is more compact in structure, which can effectively reduce the swing and loss of control probability of the vehicle.
Second, safety performance.
In terms of safety performance, the advantages of three-wave guardrail are obvious. Due to its compact structure, it can effectively reduce the probability of vehicle swing and loss of control, so it can better protect road traffic safety. In contrast, the two-wave guardrail is slightly inferior in terms of safety performance.
3. Construction and maintenance.
In terms of construction and maintenance, the two-corrugated guardrail is easier than the three-corrugated guardrail. Due to its relatively simple structure, it is relatively easy to install and disassemble, and at the same time, the maintenance cost is relatively low. Although the three-wave guardrail is compact, the installation and disassembly are relatively complex, and the maintenance cost is relatively high.
4. Scope of application.
The two-wave guardrail is suitable for ordinary highways, urban roads and other scenarios, especially some road sections with low requirements for traffic safety. The three-wave guardrail is more suitable for scenarios with high requirements for traffic safety, such as highways and mountain roads.
To sum up, there are obvious differences between the two-corrugated guardrail and the three-corrugated guardrail in terms of appearance and structure, safety performance, construction and maintenance, and scope of application. In practical applications, the appropriate type of guardrail should be selected according to specific scenarios and needs to ensure the safety and smoothness of road traffic.
