• Abstract: if sewage pipeline is encountered in the open excavation project of subway constructed in the city, it needs to be relocated before construction. This paper introduces the key points in the construction of large-diameter sewage diversion, and through the key control of these points, to achieve the expected diversion effect, so as to ensure the smooth progress of the subsequent excavation construction. 城市内施工的地铁明挖工程如遇到污水管线，则需要在施工前对污水管线进行改移工作。本文介绍了大管径污水导改施工中的施工要点，通过对这些要点进行重点控制，以达到预期的导改效果，进而保证后续的开挖施工顺利进行。
