Description

Technical Field

[0001] The utility model relates to the technical field of highway corrugated beam guardrails, and specifically provides a device for reinforcing and heightening highway corrugated beam guardrails. Background Technique

[0002] A corrugated guardrail is a combined corrugated plate movable steel guardrail used at the opening of the central isolation belt of a highway. The guardrail consists of two corrugated steel guardrail plates and two columns fixedly clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrail plates. During normal operation of the highway, the guardrail can be conveniently inserted into the pre-set insertion holes at the opening by inserting and pulling out the columns, playing a role in isolation and protection. At the same time, it echoes with the guardrail belt on the outer side of the highway, being neat, uniform, and aesthetically matched.

[0003] After retrieval, a corrugated beam guardrail that is easy to heighten, with the Chinese patent application number 201921416019.9, is disclosed. This patent relates to a corrugated beam guardrail that is easy to heighten and belongs to the technical field of road guardrails. It includes columns, anti-collision blocks, and corrugated beam plates. Installation holes are provided on the columns, and multiple installation holes are distributed along the axial direction of the columns. Installation bolts connected to the anti-collision blocks are inserted into the installation holes, and the corrugated beam plates are fixedly arranged on the anti-collision blocks. When the height of the road surface needs to be heightened and the height of the corrugated beam plates needs to be adjusted, according to the need, the position of the installation bolts is adjusted, and the installation bolts are inserted into the installation holes at a higher position to achieve the purpose of adjusting the height of the corrugated beam plates. The construction is convenient and the cost is low. At the same time, there is no need to replace any components, no additional cost is required, and the cost is reduced.

[0004] Although the above patent achieves the purpose of adjusting the height of the corrugated beam plates, the construction is convenient and the cost is low. At the same time, there is no need to replace any components, no additional cost is required, and the cost is reduced. However, in actual use, multiple installation holes in this patent are set as continuous holes, and the height of the anti-collision blocks is adjusted through the installation bolts. The height adjustment is very limited. Due to the increasing proportion of large vehicles and their development towards heavier, containerized, and increasing vehicle height, the collision position between vehicles and the guardrail has increased significantly. The passive safety measures of small passenger cars have been further strengthened, and the function of the guardrail to prevent secondary accidents has been emphasized. As a result, the adjustable height and protective ability of the guardrail plate in this patent are insufficient compared to the current highway traffic conditions in China.
