摘要
由于居民生活和市政建设的原因,城镇土壤多为回填土,腐蚀性比郊野复杂和严重,埋地钢管安全状况评估需通过周期性检测确定其变化趋势,因而有必要开展专项研究。我们在借鉴国内外相关标准的基础上,提出了适合埋地钢管安全评估的土壤腐蚀性分级标准,经200公里在役管网实际应用,取得了理想的效果。
For the reason of inhabitant sewage and city instruction activities, most of the soil in cities is backfill, whose corrosion is more complicated and grievous than the soil in urban. In order to make the decision about the variety trend, the safety assessment of underground pipe need to be checked and measured periodically. So, it is necessary to do the particular research, basing on the correlative standards overseas, we illustrate our own classification standards, which suit to classify the soil corrosion around the underground pipe. And during the application of putting 200 km pipeline on use, a good result has been confirmed.
