Corrugated Beam Steel Guardrail Old Plate Renovation Method
In order to solve the problem that the old corrugated guardrail used in the highway reconstruction or expansion is abandoned,a guardrail renovation technology is developed.The process of this technology mainly includes refurbishment preparation,old board selection,old board structure shaping,old board paint and rust removal,epoxy zinc-based polyester composite coating spraying and finished product packaging and palletizing.The key point of the technology is that the old guardrail board structure shaping,the old board paint and rust removal and epoxy zinc based polyester composite coating spraying three parts,which can make the old guardrail board meet the anti-collision grade requirements,appearance requirements and performance requirements,and effectively solve the problem of resource consumption and waste caused by the scrap treatment of the old guardrail board.Through the guardrail board renovation technology,the renovated guardrail board meets the requirements of use,and realizes the reuse of the old guardrail board,thus saving steel resources,reducing the processing process of the guardrail,reducing the construction cost of the highway,and having certain economic and social benefits.
