Description
Technical Field
The invention belongs to the technical field of road traffic facilities, and particularly relates to a combined anti-collision guardrail structure.

At present, the protection devices on the two sides of the highway and the highway are composed of upright posts and protection plates positioned on the upper portions of the upright posts, the protection plates are made of steel plates, and the upright posts and the protection plates are made of rigid materials and are also in rigid connection. When the automobile is out of control and collides with the protection plate, the protection device can prevent the automobile from turning into the waterproof ditches at the two sides of the highway or rushing into the opposite lane to collide with the automobile. However, practice proves that the protective plate with the structure has no buffering function, and the protective plate is often broken under the strong impact force of an out-of-control automobile at high speed, so that the out-of-control automobile rushes into an opposite lane to crash, and the automobile is damaged and people die; especially, the broken protective plate is more serious to hurt people, and the danger that the automobile turns into the waterproof ditches at the two sides of the highway or rushes into the opposite lane to collide can not be effectively prevented. On the other hand, the protective plate made of the steel plate is also permeable, loses the anti-pressure and anti-collision effects, has short service life, and shows an increasing trend along with the mass construction of highways, urban overpasses and the like and the great increase of the global automobile holding capacity. At present, both the upright post and the guardrail plate are made of rigid materials. The existing guard rails in the current market do not have the functions of buffering and damping when in use, when an automobile collides with a guard rail plate, the automobile can only damage energy absorption by means of deformation of the guard rail plate, and the deformation capacity and the energy absorption capacity are limited. And the guard rail plate is easy to break under the impact of the automobile, so that the guard rail cannot be normally used, and the safety of the automobile and crewmembers is easy to cause secondary damage.
