谈250km/h有砟轨道精捣精调施工要点

On construction points for refined pounding and tight alignment of 250 km /h ballast track

以250 km/h有砟轨道线路的精捣精调为例,结合线路主要的技术标准,制定了总体施工方案,阐述了有砟轨道人工精调和有砟线路大机精捣的施工方法,并总结了具体的质控措施,以确保工程质量。

Taking the refined pounding and tight alignment of 250 km/h ballast track as the example, the paper combines with the main technical standards for the route, makes the general construction scheme, illustrates the manual tight alignment of the ballast rail and the construction meth- ods for the mainframe refined pounding of the ballast rail, and sums up factual quality control measures, so as to ensure the engineering quality.
