It is necessary to meet certain external conditions and special technical requirements for the integration of gravity-flow sewage pipeline into the utility tunnel, especially when the road is flat without slope, the design is very difficult. Taking Zhuhai Chengxiang Road utility tunnel design as an example, the design key points of pipe selection, inspection well, air vent and connection well were emphasized. The cross section design, plan design, vertical design, special node design were expounded in this case. It could be used as reference for other projects that integrate gravityª²flow sewage pipeline into utility tunnel.
