【摘要】：采用热镀锌层剩余厚度和通过人工目视宏观检测的铁塔塔材表面腐蚀形貌作为评判依据,并借鉴钢材表面腐蚀程度的划分和涂层老化评级方法等相关标准,制定了输电线路铁塔腐蚀等级评定规则,并提出了处理建议。该评定规则易于输电线路技术监督人员掌握和应用,使其能够在现场快速准确地对输电线路铁塔腐蚀等级进行判定,并以此为依据制定下一步的处理方案。
[Abstract]:The residual thickness of hot-dip galvanizing layer and the corrosion morphology of tower material through manual macroscopic inspection were used as the basis for judging the corrosion degree of steel surface and the method of coating aging rating, and so on, and some related standards such as the classification of corrosion degree on steel surface and the method of coating aging rating were used for reference. The evaluation rules of corrosion grade of transmission line tower are established, and the treatment suggestions are put forward. The evaluation rule is easy to be grasped and applied by the technical supervisor of transmission line, so that the corrosion grade of transmission line tower can be judged quickly and accurately on the spot, and based on this, the next treatment scheme is worked out.
