Technical Field

[0001] The utility model relates to a corrugated beam guardrail in the field of highway safety protection, in particular to a directly reused double-layer corrugated beam guardrail structure. Background Art

[0002] In order to improve traffic conditions and increase vehicle capacity, some highways need to undergo major or medium-sized repairs or reconstruction and expansion. The existing roadside and central median corrugated beam guardrails were designed and built according to old standards and no longer meet today's safe driving needs.

If all existing guardrails are dismantled and discarded and new guardrails are purchased, the material cost and construction cost will increase, and the construction period will also be longer. In order to save construction funds and shorten the construction period, combined with the requirements of major or medium-sized highway repairs or renovation and expansion projects, based on the current status of existing corrugated beam guardrails, the existing guardrail structure is fully utilized for renovation and upgrading, and no on-site drilling or cutting is performed on the existing guardrails to prevent affecting the anti-corrosion performance of the corrugated beam guardrails, so that their safety performance meets the protection requirements of the current specifications, so as to better protect the safety of highway operations and the safety of people’s lives and property.

[0004] According to the above situation, a direct reuse type double-layer corrugated beam guardrail structure is proposed, which not only improves the protection level of the guardrail but also fully reuses the existing guardrail components. It is suitable for the renovation and upgrading project of the double corrugated beam guardrail. Utility Model Content

[0012] Furthermore, after the sleeve is installed on the top of the old column, the top height is the same as that of the new column.

[0013] Furthermore, the cross-sectional shape of the old column is a hollow cylinder, the cross-sectional shape of the new column is a hollow cylinder or a rectangular square column, and the old column and the new column are anchored to the road surface by piling or burying piles.

[0014] Furthermore, the direction of the bolt holes connecting the old column and the hexagonal anti-obstruction block is toward the collision surface of the double wave plate; the direction of the bolt holes connecting the new column and the adjustable anti-obstruction block is toward the length direction of the double wave plate, the direction of the bolt holes connecting the new column and the hexagonal anti-obstruction block is toward the collision surface of the double wave plate, and the direction of the bolt holes on the sleeve is the same as that of the old column.
