Buffering anti-collision guardrail on expressway

Abstract

The invention discloses a buffering anti-collision guardrail on an expressway. The guardrail comprises a guardrail plate, a connection vertical column, a connection buffering tray, a reinforcing vertical column, a reinforcing buffering tray and a built-in steel plate, wherein the guardrail plate consists of an outer layer pipe plate, an inner layer pipe plate body, a steel plate clamping groove pipe body and a supporting buffer column; three layers of buffering structures are formed in the guardrail, the first layer is a three-layer pressure-reducing and buffering honeycomb, the second layer is a wave-shaped built-in steel plate manufactured in the pressure-reducing and buffering honeycomb, and the third layer is a connection buffering tray or a reinforcing buffering tray arranged between the guardrail and the vertical columns. The strength, toughness and bounciness of the guardrail are enhanced; the guard rail is connected with the vertical column elastically, so that the buffering anti-collision guardrail has high buffering capacity, bounciness, elasticity and impact resistance, phenomena that automobile accidents occur, and loss is caused by the automobile accidents can be effectively avoided; and the guardrail has the advantages of long service life and low using cost.

Description

technical field [0001] The invention belongs to an expressway buffer and anti-collision guardrail. 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 top. The protective plate is made of a steel plate, and the two are rigid materials and are 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 expressway road or rushing into the opposite lane to collide ...

Problems solved by technology

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
