Study on Siphon Rainwater Drainage System of the Main Building of the High-speed Railway in South China
As a core transportation hub in South China,a high-speed railway station in the south undertakes a heavy passenger transport task.As the main building of a high-speed railway station,the station building has a large build-ing area,a small roof design slope,and there is a certain pressure on rainwater drainage.More seriously,when en-countering rainy weather,due to the insufficient inclination angle,rainwater may flow backwards into the room,caus-ing safety hazards.To solve this problem,two independent siphon rainwater drainage systems have been adopted for the station building.Based on the design of the siphon system on the main station building surface,this paper deeply analyzes the design parameters of the gutter water baffle and the overall structure of the water catchment system;By cal-culating and verifying the hydraulic pressure of the pipeline system at the lowest point of the roof structure,the impact of different node pressure values and head losses on the operation and maintenance of the siphon system is systematical-ly analyzed.At the same time,feasible suggestions are proposed to solve the possible problems in the drainage system.It is expected to provide theoretical support for the roof drainage system design of other high-speed railway stations,promote in-depth research on siphon rainwater drainage systems,and address rainwater drainage issues under different environmental conditions.
