摘要
针对既有运营铁路路基实际病害情况,对比分析了不同注浆技术的适用性,提出了精细化袖阀管注浆加固技术。该技术在陇海线等线路开展工程应用,证明了袖阀管注浆加固技术的有效性与适用性,可为类似铁路路基沉降整治提供参考。
According to the actual defects of operation railway subgrade,the applicability of different groutingtechnologies was compared and analyzed.The refined sleeve valve pipe grouting reinforcing technology was proposed.The application in Longhai line(Lanzhou-Lianyungang)and other railway lines proves the effectiveness andapplicability of sleeve valve pipe grouting reinforcing technology,which provides a reference for similar railwaysubgrade settlement treatment engineering.
