The height of the center of the guardrail in the normal section is about 60-70 cm, and the ground-anchored end gradually reduces the height of the guardrail through a gradual section with a length of about 6 m. Finally, one end of the corrugated guardrail is directly buried in the ground, and concrete is poured to anchor it. . When the vehicle runs out of control and rushes to the guardrail, the vehicle will climb up along the guardrail, converting kinetic energy into potential energy, thereby reducing speed and injury. The ground anchor type end buries a section of the guardrail into the ground, which actually hides the edge of the section and avoids the risk of the guardrail being inserted into the car.
