Problems solved by technology

[0003] At present, the guardrails used in municipal engineering are often guardrails composed of simple railings. When they are hit by cars, the guardrails will be knocked down, and the guardrails adjacent to the hit guardrails will also be damaged; resulting in road blockage, resulting in casualties and Economic loss; in this case, it is necessary to design a guardrail. When hit by a car, the guardrail will not be knocked down easily, and the impact of adjacent guardrails will not cause traffic accidents.

Abstract

The invention belongs to the technical field of municipal road and bridge engineering guardrails, and particularly relates to an anti-knock-down safety guardrail for municipal road and bridge engineering, which comprises guardrail units and connecting mechanisms, wherein the two connecting mechanisms are uniformly mounted at the upper end and the lower end between every two adjacent guardrail units; the guardrail can be prevented from being knocked down by changing the wave shape when the guardrail is knocked down by an automobile; when a bow-shaped elastic strip is subjected to large force, namely the impact force of an automobile is large enough, the straightening part is completely pulled out of the through hole of the guardrail plate, and the bow-shaped part is pulled to the gap between every two adjacent guardrail units, so that the guardrail units are changed into bow shapes; when the impact force is small, all the guardrails do not become arch-shaped, and at the moment, due to the friction between the guardrail base installed on the lower side of the guardrail shell and the ground, the friction between the guardrail plate base installed on the lower side of the guardrail plate and the ground and the traction effect of other adjacent guardrails, the guardrails cannot be knocked down or knocked far.

Description

[0001] Technical field [0002] The invention belongs to the technical field of municipal engineering guardrails, in particular to an anti-collision safety guardrail used in municipal road and bridge projects. Background technique [0003] At present, the guardrails used in municipal engineering are often guardrails composed of simple railings. When they are hit by cars, the guardrails will be knocked down, and the guardrails adjacent to the hit guardrails will also be damaged; resulting in road blockage, resulting in casualties and Economic loss; in this case, it is necessary to design a guardrail. When hit by a car, the guardrail will not be knocked down easily, and the impact of adjacent guardrails will not cause traffic accidents. [0004] The present invention designs a kind of anti-collision safety barrier used in municipal road and bridge engineering to solve the above problems. Contents of the invention [0005] In order to solve the above-mentioned defects in the p...
