Anti-collision guardrail for highway traffic safety facility engineering

Abstract

The invention discloses an anti-collision guardrail for highway traffic safety facility engineering. The anti-collision guardrail comprises a plurality of protection assemblies which are arranged on the ground side by side; the protection assembly comprises a stand column, a spherical buffering piece, a spring and a fixing disc. The bottoms of the stand columns are inserted into the ground to be fixed. End covers are arranged at the tops of the stand columns; the multiple spherical buffer pieces are arranged on the periphery of the stand column in a sleeving mode in the vertical direction, and the spherical buffer pieces are in sliding connection with the stand column. Every two vertically adjacent spherical buffering pieces are connected through a spring. The fixing disc is arranged on the lower portion of the protection assembly. The periphery of the stand column is sleeved with multiple springs. The lowest spherical buffer part is supported on the fixed disc; a buffer space is reserved between the uppermost spherical buffer piece and the end cover, and a spring is arranged in the buffer space. The anti-collision guardrail for the highway traffic safety facility engineering is convenient to disassemble and assemble, good in elastic buffering effect, good in protection effect and safer to use.

Description

technical field [0001] The invention relates to the field of anti-collision guardrails, in particular to an anti-collision guardrail for highway traffic safety facility engineering. Background technique [0002] At present, highway guardrails are generally composed of columns and guardrails. The guardrails are made of steel plates, and the two are rigid materials and are also rigidly connected. [0003] When the car loses control and hits the guardrail, the guardrail can prevent the car from rushing off the road. However, practice has proved that the guardrail with the above-mentioned structure has no cushioning function. Under the high-speed and powerful impact of an out-of-control car, the guardrail will break. . When the out-of-control car rushes out of the driveway, it is easy to cause car crashes, and at the same time, the cracked guardrail may cause secondary injuries to the driver and passengers. Contents of the invention [0004] In order to solve the technical ...

Problems solved by technology

However, practice has proved that the guardrail with the above structure has no cushioning function. Under the high-speed and powerful impact of an out-of-control car, the guardrail will break.

When the out-of-control car rushes out of the lane, it is easy to cause car crash and death. At the same time, the cracked guardrail may cause secondary injuries to the driver and passengers
