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 addi-tion,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.
