Design of Deck Drainage of Dongbao River Xinan Bridge
The main span for navigation of Dongbao River Xinan Bridge is 156 m long. It is the first combined beam structure of corrugated steel web bridge in China. The drainage of this bridge is the combination of transverse deck drainage and longitudinal drain pipe drainage. Based on the rainfall intensity, the catchment amount is rechecked,and the pipe size water discharge is designed. Also based on the rainfall duration of rainfall return period in the area of Guangdong, the pipe size tables corresponding to the allowed maximum catchment area are calculated and summarized so as to be referenced for the drainage design ofthe other bridges.
