目前,由于铁路安全、速度、负载量要求越来越高,使大型养路机械维修线路地位越来越重要,同时也是铁路提速的重要保障。然而,受到地面配合、线路状况等因素影响,造成大机维修作业之后,线路质量达不到预期效果,从而产生一定的安全隐患。本文对其原因进行探讨,并给出相应的整改建议。 At present, as the railway safety, speed and load requirements are getting higher and higher, the status of large-scale maintenance machinery repair lines is becoming more and more important, and it is also an important guarantee for speeding up of the railway. However, due to the influence of the ground coordination and the line condition, the quality of the line can not reach the expected result after the mainframe maintenance work, resulting in some potential safety problems. This paper discusses the reasons and gives the corresponding corrective suggestions.
