铁路基床在各种因素影响下,产生各种类型的永久变形,形成基床翻浆冒泥、下沉和外挤变形等基床病害,必须及时消除,才能确保线路状态良好。我国传统的采用人工换填的作业方法处理基床病害,已逐渐无法满足现在快速重载的运输条件。介绍运用挖掘机等大型机械配合处理基床病害施工技术,总结该整治路基病害施工的主要技术要求、施工天窗、限速条件等,更好地发挥其在整治铁路路基病害施工中的作用。
Under the influence of various factors, the railway bed has various types of permanent deformation, and forms bedrock diseases such as slugging, sinking, crushing and deformation of bedrock, which must be promptly eliminated to ensure the good condition of the railway. The traditional method of manual filling in our country to deal with bed disease has gradually failed to meet the current fast heavy-load transport conditions. This paper introduces the application of large machinery such as excavator to deal with the construction technology of bed disease and summarizes the main technical requirements for the construction of roadbed disease, construction skylight, speed limit conditions, and so on, to better play its role in the remediation of railway subgrade disease.
