Description
Technical Field
The invention belongs to the field of highway traffic facilities, and particularly relates to a central anti-collision isolation guardrail device for a highway.
Background
With the development of national economy, a large number of highways, expressways, etc. are being built or under construction. At present, the protection devices on the two sides of the expressway and the highway consist of upright posts and protection plates positioned on the upper parts 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 rigidly connected. When the automobile runs out of control and collides with the protection plate, the protection device can prevent the dangerous situation that the automobile turns into a waterproof ditch on two sides of a highway or rushes into an opposite lane to collide with the automobile. However, practice proves that the protection plate with the structure has no buffer function, the protection plate is often broken under the high-speed strong impact force of the out-of-control automobile, the out-of-control automobile rushes into the opposite lane to crash, the automobile is destroyed, and especially, the broken protection plate hurts people more seriously, and the danger that the automobile turns into a waterproof ditch on two sides of a highway or rushes into the opposite lane to crash can not be effectively prevented. On the other hand, the protection plate made of the steel plate is also thoroughly grown, the anti-pressure and anti-collision effects are lost, the service life is shorter, and the occurrence rate of traffic accidents also shows an ascending trend along with the great increase of mass construction of highways, urban interchange and the like and the large increase of the global automobile conservation quantity. At present, the upright posts and the guardrail plates are made of rigid materials. When the prior guard rail in the current market is used, the prior guard rail has no buffering and damping effects, and an automobile collides with the guard rail plate and can only damage energy absorption by means of deformation of the guard rail plate, so that the deformation capacity and the energy absorption capacity are limited. And the guardrail plate is broken easily under the striking effect of car, causes the unable normal use of rail guard, also causes the secondary injury to the safety of vehicle and crew, in sum, how to solve the limited problem of current highway guardrail deformability and energy absorption ability, has become the problem that the skilled person need to solve.
