重庆轨道交通6号线敞开式全断面岩石掘进机施工过站方案研究

摘要

The article introduces the engineering situation of the first stage project of Chongqing Rail Line 6, combined with machine characteristic and construction period requirements of the open tunnel boring machine, comprehensively considers the definite situation of section and station construction passed by open TBM, comes up with the go through station scheme of tunneling, empty push and go through on the middle plate of open TBM using in urban rail transition, to ensure the TBM non-stopping and rapid construction, this research provids the technical support for open TBM large-scale application in Chongqing and other cities rail transit construction.%介绍重庆轨道交通6号线一期工程敞开式全断面岩石掘进机(TBM)试验段的工程情况.结合敞开式TBM的机型特点和总工期要求,综合考虑TBM施工段所经过的区间及车站施工的具体情况,提出了敞开式TBM在城市轨道交通工程施工中掘进过站、步进过站以及步进通过车站中板的过站方案,保证TBM在站内能不停机、不等待、快速施工、顺利过站,成功解决了敞开式TBM在轨道交通施工中的过站难题,为敞开式TBM逐渐大规模应用于重庆及其它城市轨道交通工程建设提供了技术支撑.
