综合管廊集水泵坑设计规模探讨

Discussion on Design Scale of Water-collecting Pump Pit of Comprehensive Pipe Gallery

综合管廊排水系统设计中,雨水泵的选型及泵坑尺寸预留受到外部进水与内部结构渗水、管道检修等因素影响,存在较大争议,本文针对管廊内排水系统水量计算影响因素的列举,并通过计算实例及实际工程建设过程中碰到的主管部门意见等作为计算参数选取依据,为管廊工程集水泵坑设计提供思路。

In the design of the integrated pipe gallery drainage system,the selection of rainwater pumps and the reserved size of the pump pit are affected by factors such as external water intake and internal structure seepage,pipeline maintenance and other factors.The influencing factors are listed,and the calculation examples and the opinions of the competent authorities encountered during the actual project construction are used as the basis for the selection of calculation parameters to provide ideas for the design of the collection pump pit of the pipe gallery project.
