Highway guardrail

Abstract

The invention discloses a highway guardrail. The highway guardrail comprises a guardrail body installed in the middle of a road surface, the entire guardrail body is formed by splicing one or more guardrail groups, a gap cavity is formed between every two adjacent guardrail groups, each guardrail group includes more than one buried box embedded in the left and right sides, a containing cavity withan opening in the upper end is formed in the upper end of each buried box, each guardrail group also includes two groups of guardrail bars, and a sliding block is fixedly welded to the portion, opposite to the corresponding containing cavity, of the bottom of each guardrail bar. According to the highway guardrail, two buffering belts are formed on both sides of the middle guardrail body; when a vehicle runs close to a buffering belt area, buffering cushions can be used for buffering deceleration of the vehicle, and the guardrail bars can be used for warning and reminding and moved away from the vehicle for a certain distance after being pressed; in this way, the guardrail rods can be moved back after a driver is reminded to prevent the vehicle from contacting and colliding with the guardrail bars, and the highway guardrail is safer to use.

Description

technical field [0001] The invention relates to the field of municipal roads, in particular to a highway guardrail. Background technique [0002] A middle guardrail will be set up in the middle of the road on highways and municipal roads, and the middle guardrail will be used as a vehicle protection to prevent serious traffic accidents from driving into the opposite lane. The bottom of the traditional guardrail structure is fixed on the road, so that the vehicle will directly hit the guardrail after losing control, resulting in serious deformation of the guardrail and the vehicle, without a buffer and retreat ability. And sometimes, in order to prevent the driver from driving fatigue and bumping into the guardrail, reminder tapes are generally set on both sides of the guardrail. After the vehicle enters the reminder tape, there will be a strong sense of shock to remind the driver to pay attention to the vehicle track, but this structure often It is the function of reminding...

Problems solved by technology

The bottom of the traditional guardrail structure is fixed on the road, so that the vehicle will directly hit the guardrail after losing control, resulting in serious deformation of the guardrail and the vehicle, without a buffer and the ability to retreat

And sometimes, in order to prevent the driver from driving fatigue and bumping into the guardrail, reminder tapes are generally set on both sides of the guardrail. After the vehicle enters the reminder tape, there will be a strong sense of shock to remind the driver to pay attention to the vehicle track, but this structure often It serves as a reminder. Once the driver realizes that he wants to adjust the direction, he often hits the guardrail. There are many deficiencies in its design.
