Problems solved by technology

Due to the improper handling of the end of the guardrail, the guardrail board inserts and penetrates the car body after the collision, causing casualties.
After the vehicle collides with the end of the guardrail, the unreasonable design of the end structure of the guardrail, the deformation of the end, and the insufficient effect of guiding and energy absorption are the main reasons for the penetration of the guardrail after the end is damaged.
[0004] The current "Code for Design of Highway Traffic Safety Facilities" only stipulates the setting principle of the end of the guardrail, and does not give a specific structure of the end of the guardrail with anti-collision capability, and the structure of the end of the guardrail in the prior art has been unable to meet the needs of the road.

Abstract

The invention relates to the technical field of highway anti-collision facilities and discloses a guardrail terminal and a guardrail, which are used for improving the guiding performance, buffer strength and anti-collision energy of guardrails and improving safety of personnel in vehicles. The guardrail terminal comprises at least two stand columns arranged on a roadside, an end guardrail plate, an energy absorption anti-collision device, brackets fixed with the stand columns one to one and a guide pipe, wherein the end guardrail plate penetrates through the energy absorption anti-collision device and is fixed with a foundation, the guide pipe extends along an arrangement direction of the at least two stand columns arranged on the roadside, the two ends of the guide pipe are fixed with the foundation, the energy absorption anti-collision device sleeves the guide pipe, an open groove towards a vehicle running direction is arranged on each bracket, one end of each fixing bolt penetrates through the open groove and is connected with a corresponding stand column bolt hole to fixedly connect the end guardrail plate and the energy absorption anti-collision device with the corresponding stand column.

Description

technical field [0001] The invention relates to the technical field of highway anti-collision facilities, in particular to a guardrail end and a guardrail. Background technique [0002] In recent years, my country's traffic construction has developed rapidly, and the road mileage and motor vehicle volume in my country have also increased rapidly. The contradiction between road traffic safety and rapid economic development has become increasingly prominent. [0003] At present, the ends of conventional highway guardrails in China are mostly extended and anchored below the ground or extended to the soil road shoulder at the end of the wave beam guardrail. After the vehicle collides with the end of the guardrail, the vehicle is likely to climb along the anchorage guardrail or break the end of the guardrail and drive out of the road. Due to the improper handling of the end of the guardrail, the guardrail plate is inserted into and penetrates the car body after the collision, ca...
