摘　　要：介绍了成都天府国际机场航站区室外排水管道设计,重点分析了减少管道埋深的措施和结构基础对排水管道布置的影响。项目排水管道与传统建筑工程的排水管道相比,其管径更大,覆土更深,与市政排水管道相比,其安装受到更多的限制。针对狭窄空间,对传统跌水井进行改进,提出了一种尺寸更小、安装更灵活的跌水井方案。其中,设计了一种供多支管接入的矩形混凝土检查井,可有效减少支管检查井数量,节省造价。Outdoor drainage pipework design for terminal area of Chengdu Tianfu international airport was introduced in this paper.The measures to reduce the buried depth of the pipelines and the influence of the structural foundation on the layout of the drainage pipelines were emphatically analyzed.Compared with the drainage pipes of common building projects,the drainage pipes of this project have a larger diameter and deeper soil cover,and their installation is more limited than that of municipal drainage pipes.For the narrow space,the traditional drop well was improved,and a new drop well scheme with smaller size and more flexible installation was proposed.In addition,a new type of rectangular concrete well for multiple branch pipes was designed,which could effectively reduce the number of branch wells and save cost.
