| Cause analysis and countermeasures of defect-missing during railbolt- hole cracking detection |
| 摘要 |
| 在日常的鋼軌探傷作業(yè)中螺孔裂紋易被發(fā)現(xiàn)，，按規(guī)定螺孔裂紋為重傷必須進(jìn)行更換。但在實際養(yǎng)護維修中，由于受維修天窗時間和周轉(zhuǎn)鋼軌等條件的限制,存在無法及時更換的情況，尤其個別膠結(jié)接頭由于探傷工無法抽取傷損螺栓進(jìn)行驗證，膠結(jié)接頭較易形成安全隱患。結(jié)合現(xiàn)場探傷實際 |
