- Abstract:
- Urban road tunnel is an important part of urban three?dimensional transportation and significant facility for improving the smooth operation of urban transportation. The design of efficient drainage system is one of the key factors for keeping a tunnel in good function. This paper introduced the design of Beijing Normal University road tunnel drainage system of Jinqin Expressway between Gangwan Avenue and Meihua Interchange in Zhuhai. The water catchment area of the tunnel is about 1.54 hm2, and the design flow of the drainage pumping station with an independent drainage system is 1 260 L/s. There are four submersible sewage pumps (three in use and one as backup) to pump the rainwater to the current Jinfeng Road flood discharge channel on the east side of the tunnel. The project has been running well after completion.
