南京地铁试验段旁通道水平冻结法施工技术

Construction Technology Analysis of the Horizontal Freezing Method Adopted in Construction of Side Channels of the Test Section of Nanjing Subway

结合南京地铁试验段旁通道冻结法施工,分析总结了冻结法在冻结管施工、冻结、开挖构筑等阶段的施工技术难点及对策,可以为今后旁通道冻结法施工提供一定的参考。

Combining the freezing method construction of side channels of the test section of Nanjing subway, authors analyze and conclude some technical problems and countermeasures of the freezing method in different construction stages such as construction of freezing pipes, frezzing, excavation and so fort. The conculusion can be referred by future freezing method construction of side channels.
