Multi-stage buffering highway barrier structure

Abstract

The invention relates to a multi-stage buffering highway barrier structure and belongs to the technical field of highway barriers. The multi-stage buffering highway barrier structure comprises a firstbuffering part, a second buffering part, connecting parts and an upright; the first buffering part is positioned on one side close to a highway and clamped in the second buffering part; the second buffering part is connected with the upright through the upper and lower connecting parts; the first buffering part comprises an anti-collision barrier plate, a filling layer, a vibration absorbing plate and bolts in sequence from outside to inside; the second buffering part comprises a grooved base and a spring layer; and the connecting parts comprise telescopic rods and elastic buffering blocks. The multi-stage buffering highway barrier structure has the advantages that the deformation ability and energy absorbing ability of the barrier are improved, a vehicle body and the crew can be effectively prevented from being damaged and injured by the broken rigid barrier plate, the safety performance of the highway barrier is enhanced, the vehicle loss is reduced, the human safety is guaranteed,the use effect is good and the practicability is high.

Description

technical field [0001] The invention relates to a multi-stage buffer highway guardrail structure, which belongs to the technical field of highway guardrails. Background technique [0002] With the massive construction of highways and urban interchanges and the substantial increase in global car ownership, the incidence of traffic accidents is also on the rise. At present, the protective devices on both sides of the expressway are mainly composed of columns and guardrails on their tops. The guardrails are made of steel plates, and both the columns and the guardrails are rigid materials. At present, the existing guardrails on the market do not have the function of cushioning and shock absorption when they are in use. When a car hits the guardrail, it can only rely on the deformation of the guardrail to damage the energy absorption, and the deformation and energy absorption capabilities are limited. And the guardrail board is easy to break under the impact of the automobile, c...

Problems solved by technology

At present, the existing guardrails on the market do not have the function of cushioning and shock absorption when they are in use. When a car hits the guardrail, it can only rely on the deformation of the guardrail to damage the energy absorption, and the deformation and energy absorption capabilities are limited.

And the guardrail board is easy to break under the impact of the car, causing the guardrail to be unable to use normally, and it is also easy to cause secondary damage to the safety of the vehicle and the crew.

[0003] To sum up, how to solve the problem of limited deformation ability and energy absorption ability of the existing expressway guardrail has become a problem to be solved urgently by those skilled in the art
