宁芜线K65+198～+834位于慈湖与马鞍山站间,该段基床翻浆冒泥,线路沉陷,尤其是雨季,更为严重,整段线路“雨天水汪汪,晴天稀泥浆,道上不见枕,遍地黄荡荡”;由于翻浆冒泥、沉陷,轨面变化大,零配件损伤严重,养护工作量大大增加,时刻危及行车安全,曾经过数次处理及整治,由于当时资金紧缺,认识尚不一致,因而基床病害未能彻底根治,随着运量的增加,列车密度和行车速度不断增加,基床病害愈来愈恶化,严重地威胁运输安全。 1914年,对病害经过认真细致地调查和分析研究,采取了综合整治方法,取得了明显的效果,三年来通过九千多万吨运量,基床稳定,轨道几何状态良好,行车平稳,轨检车评分均为优良。 Ningwu line K65 + 198 ~ + 834 is located in Cihu and Ma’anshan station, this section of the bed frost mud, the line subsidence, especially the rainy season, more serious, the whole line “Rainy water, sunny days, mud, on the road missing Pillow, all over the yellow swing ”; due to the dumping mud, subsidence, rail changes, serious damage to spare parts, maintenance workload greatly increased, always endanger driving safety, had several treatment and remediation, due to lack of funds at that time, understanding Is not consistent, so the bed disease can not be completely eradicated, with the increase of traffic volume, train density and driving speed is increasing, more and more worse bedrock disease, a serious threat to transport safety. In 1914, the disease was carefully investigated and analyzed. Comprehensive treatment measures were adopted and remarkable results were achieved. In the past three years, it passed more than 90 million tons of transportation capacity, with stable foundation bed, good orbital geometry, smooth running, Check car ratings are excellent.
