Problems solved by technology

[0005] In order to solve the problems that the impact force cannot be unloaded when a high-speed vehicle collides with the guardrail, and secondary rebound collisions are likely to occur, the present invention provides a highway guardrail that quickly absorbs the kinetic energy of the vehicle and quickly separates the absorbed kinetic energy from the guardrail. The technical scheme adopted is as follows:

Abstract

The objective of the invention is to solve problems that when a vehicle running at a high speed collides with a guardrail, impact force cannot be unloaded, and secondary springback collision is likelyto happen. The invention provides an expressway guardrail capable of quickly absorbing kinetic energy of an automobile and quickly separating the absorbed kinetic energy from the guardrail. The expressway guardrail comprises a base and a plurality of vertical connecting rods fixedly connected to the upper portion of the base, and is characterized in that a horizontal fixing groove is fixed to theupper portions of the connecting rods, the cross section of the fixing groove is in a U-shaped opening shape, and an opening faces the right hand side in the advancing direction; a column body capable of being separated from the fixing groove and being crushed is arranged in the fixing groove; after a vehicle running at a high speed is impacted, the columns in the fixing grooves are damaged and slide down, impact force generated by impact of the vehicle is partially transferred, damage to the vehicle is reduced, and meanwhile secondary impact caused by a guardrail generally provided with buffering or springback components is avoided.

Description

technical field [0001] The invention relates to the technical field of road protection, in particular to a highway guardrail. Background technique [0002] At present, when a high-speed vehicle collides with a guardrail in an accidental traffic accident on an expressway or other roads, the impact force generated by the impact is relatively large, and the impact force often forces the vehicle to stop by forcible impact, which will cause the vehicle to be damaged. The damage is serious, and even the injuries to the occupants of the car are also serious. [0003] At present, the existing technology is to reduce the kinetic energy of the car by increasing the elasticity or cushioning performance of the guardrail to absorb the kinetic energy of the car, thereby reducing the speed of the car and reducing the damage to the car and people. [0004] However, this kind of guardrail with elasticity or cushioning performance is realized by absorbing kinetic energy, and the kinetic ener...
