无内支撑两墙合一逆作法在深基坑施工中的应用

The Application of Reversed Construction Method of Dual-Purpose Diaphragm Wall Without Internal Support in the Construction of Deep Foundation Pit

本研究以中铁上海局承建的上海白龙港污水处理厂扩建二期工程W2.3标为例,着重介绍了大型污水泵站圆形地连墙、无内支撑逆作内衬施工技术、基坑监控量测、污水泵站超长内衬防水技术,以为保障无内支撑两墙合一逆作法的施工质量提供借鉴和参考。

This study takes the W2.3 section of the second phase of the extension project of Shanghai Bailong port sewage treatment plant built by the CREC Shanghai Group as an example, it emphatically introduces the round connecting wall of large sewage pumping station, construction technology of inner lining without internal support, foundation pit monitoring measurement, and the waterproof technology of super long liner in sewage pumping station, so as to provide reference for ensuring the construction quality of the reversed construction method of dual-purpose diaphragm wall without internal support.
