冻结法施工旁通道地段铺轨过渡施工管理

地下线铺轨施工在遇到冻结法旁通道施工地段时,为减少或避免因冻结法旁通道沉降不稳定对轨道结构带来的不利影响,加快施工进度,通常采取临时过渡方法。介绍了冻结旁通道施工对轨道结构的影响和采取的对策,以及旁通道地段过渡施工的管理。组织好冻结法旁通道地段铺轨过渡施工,合理制定过渡方案,加强过渡施工期间管理,对确保工程质量、进度、安全具有重要意义。

Transition Construction and Management of Track-laying in Freezing Method Built Metro Bypass

When the track-laying of underground line encounters the metro bypass constructed by freezing method,temporary transition methods are usually adopted in order to reduce or to avoid the adverse effects of the track structure,which are often caused by the subsiding instability of bypass constructed by freezing method and by the accelerated progress of the engineering.The influence of metro bypass construction through freezing method on the track structure,the countermeasures and the transition construction management of metro bypass are introduce.How to organize the transition construction of track-laying in metro bypass constructed by freezing method,formulate rationally the transition program and strengthen the management during the engineering are of great significance to ensure the quality,progress and security of the construction.
