摘　　要：在市政污水管网施工过程中,往往存在新建超深大型污水管道的新管接驳施工。对于超深大型污水管道接驳而言,其原状管污水排量大,实施临排条件苛刻,无法长时间封堵。因此超深大型污水管道施工如何确保新旧管道安全、快捷的接驳成为当下市政管网工程的难题。依托于惠州金山新城水环境工程,对超深满水带压污水井接驳进行深入研究,采取检查井井碰井的工艺,并引进专业的潜水员作业班组,总结一套深基坑满水带压管网接驳技术。During the construction of municipal sewage pipe network,it is often necessary to construct a new pipe connection for a new super-deep and large sewage pipe.For the connection of super-deep and large-scale sewage pipeline,the original sewage discharge in the pipeline is large and the discharge conditions are harsh,so it can not be blocked for a long time.Therefore,how to ensure the safe and fast connection between the old and the new pipelines in the construction of super-deep and large sewage pipeline becomes a difficult problem in the municipal pipeline network engineering at present.Based onHuizhou Jinshan New City Water Environment Project,this paper makes a deep study on the connection of ultra-deep full water and pressurized sewage well.A set of connection technology of full water and pressurized pipe network in deep foundation pit is summarized by adopting the process of checking well collision and introducing professional diving crew.
