城市道路雨水口实施重点和优化措施探讨

Discussion on the Implementation Focus and Optimization Measure of Urban Road Gully

雨水口作为城市道路雨水系统的重要附属构筑物,是雨水管渠汇集地面径流的主要通道,也是雨水系统中位于路面、易受外界环境影响的设施。雨水口设计的合理性、施工精细度和维护有效性都是影响路面径流及时排入雨水系统的重要因素,为保证雨水口及时汇集路面径流,减少路面渍水,文章针对上述三个因素,提出城市道路雨水口的实施重点和优化措施,旨在为新建道路和既有道路的雨水系统改造提供参考。

As an important accessory structure of urban road rainwater system,gully is the main channel for rainwater pipe to collect surface runoff,and it is also a facility located on the road surface and vulnerable to external environment in the rainwater system.The design rationality,construction fineness,and maintenance effectiveness of the gully are all important factors affecting the timely discharge of road surface runoffinto the rainwater system.In order to ensure that the gully can collect road surface runoffin time and reduce road surface waterlogging,this paper puts forward the implementation focus and optimization measures of urban road gully according to the above three factors,aiming at providing reference for the reconstruction of rainwater system of newly-built roads and existing roads.
