高速铁路CRTSⅡ型无砟轨道板水泥乳化青砂浆灌注封边技术

摘要

In view of the technology of edge sealing by grouting cement emulsified asphalt mortar for the slabsof CRTS II ballastless track on Beijing-Shanghai High speed railway, author of the paper carried out a lot ofin-situ technological tests, designed some edge sealing methods suitable for domestic high speed railways.Through analysis and comparison, the advantages and disadvantages of these sealing techniques aresummarised.%针对京沪高速铁路CRTSⅡ型板式无砟轨道水泥乳化沥青砂浆灌注施工工艺,通过施工现场大量的工艺试验,设计了适合我国高铁建设国情的几种灌浆封边方式.通过对几种封边方式的分析、比较,总结了这几种封边方式的优劣性和适用性.
