轨道交通地下区间内置式废水泵房设计研究

Design of Built-in Wastewater Pump Station of Rail Transit Interval Tunnel

内置式废水泵房的研究和应用解锁了轨道交通地下区间联络通道和废水泵房之间的“捆绑”关系,可减小区间联络通道的开挖深度,降低砂性承压水风险地层内区间联络通道的施工风险。研究中综合考虑了给排水、结构、轨道、限界、供电等相关专业需求,对区间内置式废水泵房的方案进行了分类、优化和完善,对工程设计具有指导意义。

The study and application of built-in wastewater pump house unlock the"bond"relationship between the cross passage and wastewater pump station in rail transit tunnels,which can reduce the excavation depth of the cross passage and the construction risk of the cross passage in the sandy soil with confined water.In the study,the comprehensive consideration is given to the needs of water supply and drainage,structure,track,track gauge,power supply and other related specialties.The built-in wastewater pump station scheme is classifed,optimized and improved,which is of significance to the engineering design.
