Description
Technical Field
The utility model belongs to the technical field of highway safety facilities, and particularly relates to a waveform beam guardrail structure with an adjustable upright post height.
Background
The wave beam guardrails are usually installed on the two sides and the center isolation layer of the expressway, are one of the most main parts of the traffic safety facilities, and are longitudinal energy absorption structures and act as follows: the collision energy of the vehicle is absorbed through self deformation, so that the running direction of the vehicle is changed, the vehicle is prevented from going out of the road or entering the opposite lane, and the injury to passengers is reduced to the greatest extent.
The wave beam guardrail mainly comprises the following components: guardrail beam plate, stand and guardrail anti-blocking piece. The guardrail beam plate is installed on the upright post through the guardrail anti-blocking block, and then the upright post is installed on the ground.
However, in carrying out the present utility model, the inventors have found that existing wavy beam guard rails suffer mainly from the following disadvantages:
(1) The protection height requirement of the guardrail after the road surface is additionally paved can not be met by the traditional wave beam guardrail. The service life of the highway guardrail is 15 years, and the corrugated beam guardrail needs to be modified at least twice by taking 5 years as a pavement maintenance period. After the pavement is paved, the actual protection height of the guardrail is reduced, and the protection capability is reduced.
(2) After the pavement is paved, engineering economy for improving the traditional wave beam guardrail is poor, and implementation is difficult. Because traditional ripples roof beam guardrail does not reserve the design to the road surface with shop the condition that the back guardrail protection height is not enough, when the road surface with shop the transformation, for guaranteeing the protection height of guardrail, need pull out existing guardrail stand, change to can satisfy the new stand of guardrail protection height and burial depth requirement simultaneously and reset, engineering cost is high, construction convenience is bad, and the construction is great to the influence of road operation.
Therefore, the problem of continuous utilization of the traditional waveform beam guardrail in road pavement paving reconstruction is solved, so that the waveform beam guardrail still has the protection height and excellent protection capability meeting the requirements after pavement paving, and has important significance. At present, no effective solution with convenient reconstruction and good economical efficiency exists.
