How Much Impact Can Crash Barrier Withstand

Crash Barrier is an important facility for road safety protection.
In terms of design, crash barriers come in different types and structures to deal with impact forces. Common rigid crash guardrail, such as concrete guardrail, it relies on its own high strength and mass to resist the impact, can withstand a large horizontal impact, generally can withstand several tons of heavy vehicles at a higher speed impact. The principle is to use the stability of its own structure to prevent vehicle penetration.
There is also a semi-rigid crash barrier, such as a corrugated beam crash barrier. It is composed of wavy beam plate, column and block. When the guardrail crashes, the corrugated beam plate absorbs part of the energy through deformation, and the column and the block work together to disperse and transfer the impact force. Generally, it can withstand the energy generated by the impact of medium-sized vehicles at a certain speed, which can effectively reduce the damage of vehicles and personnel.
In addition, flexible crash guardrail such as cable guardrail, through the tensile deformation of the cable to buffer the impact of the vehicle. Although the carrying capacity of a single cable is limited, the overall system can slow down the speed of the vehicle to a certain extent, and is suitable for sections with high landscape requirements and low speed.
The impact bearing capacity of anti-collision guardrail is affected by many factors such as material quality, structural design, installation quality, etc. Scientific and reasonable design and construction is the key to ensure its performance.
