摘要
通过上海地铁2号线联络通道采取液氮冻结修复排水管的工程实践,介绍了液氮冻结加固施工技术的液氮冻结设计、冻结施工工艺以及冻结加固的效果。这为今后类似排水管修复工程提供经验。
Through a case of the link passage of Shanghai Rail Line 2 adopting the technique of li-quefied nitrogen frozen repairing drainage pipeline, the design of the technique and the effect of frozen & strengthening construction were introduced, which could provide experience for similar projects in the future.
