Background
At present, high-speed anti-collision guardrails can be roughly divided into concrete guardrails, square beam guardrails, wave-shaped steel beam guardrails and the like, wherein the wave-shaped steel beam guardrails are the most common. The wave-shaped steel beam guardrail has certain rigidity and toughness, and when a vehicle collides with the guardrail plate, the plastic deformation of the guardrail plate is large. The principle is that after the automobile collides with the guardrail plate, the huge impact force generated by the automobile is mainly absorbed by deformation of soil base, upright posts, cross beams and the like. However, when the automobile runs at a certain speed and collides with the guard rail, the guard rail cannot fully absorb the kinetic energy generated by the automobile, and the rest of the kinetic energy is converted into energy for damaging the automobile, so that the greater the speed, the greater the energy, and the stronger the damage to the automobile.

Detailed Description
The novel highway anti-collision guard rail disclosed by the utility model is further described in detail below with reference to the accompanying drawings and specific embodiments:
the highway anti-collision guardrail plate comprises honeycomb anti-blocking blocks, the main components of the highway anti-collision guardrail plate are hexagonal or circular structural units, spring steel can be used as materials, the highway anti-collision guardrail plate can bear a certain load due to the elastic deformation capacity, and permanent deformation cannot occur after the load is removed. Through the different arrangement combination of the structural units, a larger hexagon is formed, a certain gap is reserved between each structural unit, and each unit is connected through filling foam or other elastic materials to finally form a complete construction. This construction is known as a honeycomb block.
The anti-blocking block is connected with the upright post by a screw, so that a complete whole is formed. When the external impact force is received, the anti-blocking block can absorb a part of energy through self crumple, so that collision to a vehicle and casualties of personnel can be reduced, the baffle plate and the upright post can be protected, and the replacement times of the baffle plate and the upright post can be reduced.
The outer side of the upright post is additionally provided with a blocking foot which is connected with the upright post by elastic damping. The fender foot adopts concrete structure, forms half surrounding structure to the stand, when the stand received the power that comes from wave form guardrail board transmission, and a part passes through the shaft and transmits for the basis, and another part then transmits for the fender foot through elastic damping, and keeps off the foot and can prevent that the shaft from inclining to the outside, and elastic damping can play very big effect, when slowing down the camber force, returns to store in releasing a part of energy, gives the stand certain power and keeps out the power that the collision produced.
Examples
As shown in fig. 1 above, the honeycomb-shaped elastic damping block can be divided into two parts, one part being an outer structure 1 and the other part being an inner filler material 2, and the construction is connected to the corrugated baffles and the columns by bolts 3 and 4. The outer structure 1 is mainly a hexagonal unit, is formed by bending and folding a spring steel into the shape shown in the above figure, and is finally connected by welding. The middle filling material 2 is an elastic porous material such as foam filled into the gaps during welding, so that on one hand, each hexahedral structure unit can be connected, the whole body is more stable, on the other hand, the elastic material can better absorb the impact force generated by automobile collision, the damage to the automobile body and the casualties of people are further reduced, and the deformation cannot occur after the load disappears. The combination of the two can fully play the role of elastic damping. The honeycomb-shaped elastic damping anti-blocking block is connected with the wavy baffle through the bolt 3, and the honeycomb-shaped elastic damping anti-blocking block is connected with the upright post through the bolt 4, so that the honeycomb-shaped elastic damping anti-blocking block, the upright post and the upright post form a problem and play roles together.
The following modifications can be made to fig. 1, as shown in fig. 2 and 3, in which the anti-blocking block with the internal elastic double-cylinder structure can be divided into two parts, one part is a common external structure 1, the other part is a double-cylinder structure 10 with the internal elastic double-cylinder structure, the anti-blocking block is connected with the corrugated guard board through bolts 3 and 4, and the upper and lower connecting pieces 6,7,8 and 9 are fixed in the middle through the middle structure 5 to prevent the upper and lower sliding. The upper cylinder and the lower cylinder are closely attached to the hexagonal anti-blocking block, the bolts 3 and 4 are connecting pieces of the anti-blocking block on the upright post and the waveform guard baffle, and the middle structure 5 is a middle piece when the double-cylinder structure is put in.
The connection of the upright post and the soil base is also a key node, as in fig. 4, a retaining foot 11 is additionally arranged on the outer side of the upright post, and is connected with the upright post by an elastic material, which can be foamed ceramic 12 for absorbing energy.
