The application of inclined vertical drainage pipes is an attempt and innovation to solve the drainage problems of special architectural shapes.Based on the unique architectural de-sign,compare and select the layout of drainage risers to determine the feasibility of using inclined drainage risers.Analyze the spatial layout of inclined pipes through BIM models,and select the op-timal drainage branch pipe connection method and angle.Conduct simulation of gas-liquid two-phase flow,first simulate the vertical drainage riser under the same height difference conditions,verify the consistency between the simulated values and the standard values in the specifications,and then simulate the inclined riser under the design second flow rate.Determine the drainage ca-pacity of the inclined riser drainage pipe by measuring the maximum value of the intermediate fre-quency fluctuation pressure at the most unfavorable point with a sampling period of 10 ms.
