摘要
上海轨道交通9号线九亭站2号出入口深基坑开挖采用SMW(劲性水泥土搅拌连续墙)工法围护,施工中由于受电力排管的影响,SMW工法围护结构需进行间断处理。在对电力排管进行悬吊保护后,通过静压钢板、槽钢施作间断部分的围护结构,再结合背后注浆防水,顺利地完成了基坑的开挖。结合工程施工情况对该处理技术进行了总结,以期对类似工程提供借鉴。
The foundation pits for the No. 2 access of Jiuting Station of Shanghai rail transit Line 9 is excavated with the retaining and protection of SMW method, which is affected by the 2.0 - 0.9m power piping in the construction and requires the interrupted treatment. This paper summarizes this construction technology on the basis of this project, argues this technology can be taken for reference in similar works.
