Description

A wave beam guardrail structure with adjustable column height

technical field

The utility model belongs to the technical field of highway safety facilities, in particular to a wave-beam guardrail structure with adjustable column heights.

Background technique

Wave beam guardrails are usually installed on both sides of the expressway and the central isolation belt. The wave beam guardrail is one of the most important parts of traffic safety facilities. It is a longitudinal energy-absorbing structure. Its function is to absorb vehicle collision energy through self-deformation, Thereby changing the driving direction of the vehicle, preventing the vehicle from going out of the road or entering the opposite lane, and minimizing the damage to the occupants.

The composition of the wave beam guardrail mainly includes: guardrail beams, columns and guardrail anti-blocking blocks. The guardrail beam plate is installed on the column through the guardrail anti-blocking block, and then the column is installed on the ground.

However, in the process of realizing the utility model, the inventors found that the existing corrugated beam guardrail mainly has the following deficiencies:

(1) The traditional wave beam guardrail cannot meet the protection height requirements of the guardrail after paving the road. The service life of expressway guardrail is 15 years, with 5 years as a pavement maintenance cycle, the wave beam guardrail needs to be reconstructed at least twice. After the pavement is overlaid, the actual protection height of the guardrail is reduced, and the protection ability is also reduced.

(2) After the pavement is overlaid, the project of transforming the traditional wave beam guardrail is not economical and difficult to implement. Since the traditional wave-beam guardrail has no reserved design for the insufficient protection height of the guardrail after the pavement is overlaid, when the pavement is rebuilt, in order to ensure the protective height of the guardrail, it is necessary to remove the existing guardrail column and replace it with a guardrail that can meet the requirements of the guardrail at the same time. The new pillars required for the protection height and buried depth are reset, the project cost is high, the construction convenience is not good, and the construction has a great impact on road operation.

It can be seen that how to effectively solve the problem of continuous utilization of traditional wave beam guardrails in road overlaying and reconstruction, so that the wave beam guardrails still have the required protection height and excellent protection ability after road overlaying is of great significance. At present, there is no effective solution with convenient reconstruction and good economy.
