Introduction to highway guardrail network

Design principles of highway guardrail network

Highway guardrail network, especially when vehicles face emergency situations and dodge or lose control and rush off the road, causing accidents to inevitably occur, the safety of highway guardrail network becomes crucial. Although highway guardrails cannot reduce the occurrence of accidents, they can greatly reduce the number of casualties caused by accidents.
The principle of highway guardrail network's safety function: high-speed vehicles have great kinetic energy. When an emergency occurs, vehicles will rush towards the highway guardrail for reasons such as evasion or loss of control. At this time, the function of the highway guardrail network is to prevent violent vehicle collisions and casualties.
Safety design of highway guardrail network: The kinetic energy of a vehicle is related to its mass and speed. The model, mass and speed of currently common small cars have kinetic energy at 80km and 120km respectively. The masses of these cars are roughly equal, and the maximum speed the vehicle can reach is the main factor that determines the kinetic energy of the vehicle.

The use effect and maintenance of highway guardrail net
1. Not only has the structure reasonable but also has excellent functions.
2. Echoing the surrounding environment, the overall feeling is beautiful. Highway guardrail nets are mainly used for fences in highways, railways, airports, stations, service areas, bonded areas, open-air storage yards, ports and other fields. Such guardrail nets can beautify the environment, are durable and strong, and are not easy to fade. It is also not easy to be bent. The choice of upright columns is generally common round tubes with a cover on the top.
Installation accessories: The mesh and columns are connected with screws and various special metal clips or with wire binding. The screws used are designed to be anti-theft. After rust removal, grinding, passivation, vulcanization and other technologies, plastic plating is used, and the color is green. The plating powder is made of imported weather-resistant resin powder with better anti-aging properties. The coating must be the same color, the surface is smooth, and the color is green. Sagging, dripping, or excess clumps are allowed. The surface of the plated parts should be free of defects such as missing plating and exposed iron.
