But practice has proved that the protective plate of the above structure has no cushioning function. Under the high-speed and powerful impact of an out-of-control car, the protective plate will often be broken. People are more serious, and it cannot effectively prevent the car from turning into the waterproof ditch on both sides of the expressway or rushing into the opposite lane to crash.
On the other hand, the protective plate made of steel plate is also raw, loses the effect of anti-pressure and anti-collision, and has a short service life

Description
technical field [0001] The invention relates to an anti-collision guardrail installed and fixed close to the overtaking lane of an expressway. Background technique [0002] At present, the protective devices on both sides of the expressway are composed of a column and a protective plate positioned on its upper part. The protective plate is made of a steel plate, and the two are rigid materials and are also rigidly connected. When the car loses control and hits the protective plate, the protective device can prevent the car from turning into the waterproof ditch on both sides of the expressway or rushing into the opposite lane to crash. But practice has proved that the protective plate of the above structure has no cushioning function. Under the high-speed and powerful impact of an out-of-control car, the protective plate will often be broken. People are more serious, also can't effectively prevent automobile from turning over into the waterproof ditch on both sides of expre...
