摘　　要：西北某工业园区污水处理厂污水管网接入工程,由于设计和施工时对高地下水位地质条件考虑不足,导致第一次施工产生一系列问题,第二次施工过程中针对施工现场的实际情况,充分吸取第一次施工中的经验和教训,通过合理确定降水井的数量和井位的布置、改变三通溢流井和接入管的材质,采用适用于高地下水位地质条件的施工方法,取得了成功。以此为例,总结出高地下水位地质条件下管网接入的施工方法和注意事项。Because there was insufficient consideration of geological conditions of high groundwater level in the design and construction of the connection engineering of sewage pipe network to sewage treatment plant in an industrial park in Northwest China, a series of problems occurred during its first construction. According to the actual situation of the construction site, the successful second construction was achieved by drawing experience and lessons from the first construction, reasonably determining number and location of dewatering wells, changing the material of tee overflow well and connection pipe and using construction methods suitable to geological conditions of high groundwater level. In this instance, the construction method and matters needing attention in connection of sewage pipe network under geological conditions of high groundwater level were summarized.
