下穿式立交排水设计要点探讨

Discussion on Key Points of Drainage Design for Underpass Interchange

通过分析城市下穿式立交排水的特点及原理,结合相关规范及工程实例,对汇水范围划定、设计参数选取、雨水收集系统及雨水泵站工艺等设计中存在的问题进行探讨,并提出了合理化建议。

Based on the analysis of the characteristics and principles of urban underpass interchange drainage, combined with relevant codes and engineering examples, the problems existing in the design of catchment scope delimitation, design parameters selection, rainwater collection system and rainwater pumping station technology are discussed, and rationalization suggestions are put forward.
