1. Highway guardrail commonly used anti-corrosion treatment methods are hot-dip galvanizing method and spraying method, anti-corrosion treatment of the guardrail plate life is greatly extended, so the highway guardrail anti-corrosion treatment is very important. Due to inappropriate operation in construction, may damage the anti-corrosion layer, reduce its service life, so when found to galvanized guardrail surface damage, should be timely processing, can not make good use of high concentration of zinc-rich paint repair.
2. In the construction, the material of various equipment should be accurately controlled, especially the accurate position of various pipelines buried in the roadbed, and no damage should be caused to the public equipment in the construction process. If encounter public communication pipeline . Drainage pipeline or culvert top soil depth is insufficient, should adjust the position of the column, or change the column fixed way.
3. After the installation of the highway guardrail column, the column can be installed on the anti-block and other connecting parts, do not put too tight when installing the connecting parts, the first will be fixed with the highway guardrail connecting parts. Usually have to fix the guardrail plate first, and pay attention to the driving direction when splicing. In the installation we can fine-tune until the installation in place, and then tighten the screws
