基于郑州特大暴雨后城市雨水系统设计的建议

摘要:

郑州“7.20”特大暴雨突袭之下,郑州雨水工程基础设施受到了前所未有的考验,在新标准、新规范的指导下,城市现有雨水系统的提标改造已提上日程,本文以郑州高新技术产业开发区雨水系统为分析对象,提出改造城市雨水系统设计的5点建议：综合考虑区域现状,设定雨水工程设计标准；结合重大基础设施探讨区域性提标；结合城市竖向合理设计雨水系统；结合上下游的建设,完善老城区主管网的提标方案；建立管网系统和道路大排水系统的耦合模型合理设计行泄通道。

Abstract:

Accompanied by the “7.20” urban rainstorm flood disaster in Zhengzhou, the storm water engineering infrastructure of Zhengzhou has been suffered a big test unprecedentedly. Under the guidance of new standards and new norms, the upgrading and reconstruction of the existing urban rainwater system has been put on the agenda. This article takes the rainwater system of Zhengzhou High-tech Industrial Development Zone as the analysis object and proposes 5 suggestions for the transformation of the urban rainwater system design: Comprehensively consider the regional status quo, set design standards for rainwater engineering; discuss regional upgrades in conjunction with major infrastructure; rationally design rainwater systems in combination with urban verticals; combine upstream and downstream construction to improve the upgrade plan for the main network in the old city; establish a coupling model of the pipe network system and the road drainage system to design the drainage channels reasonably.
