- Abstract:
- A deep tunnel drainage system was applied in the sewage transmission system project of Wuhan Dadonghu Core Area. The end of the tunnel is the Beihu deep tunnel pumping station, with a design capacity of 100×104 m3/d. It is a pressure flow pumping station with underground depth of 46.35 m and net lifting height of 16.1-22.4 m. Six centrifugal pumps, including 4 working pumps and 2 spare pumps, were applied, and the working range was Q=2.79-3.87 m3/s and H=196.3-304.4 kPa. In the design of the Beihu deep tunnel pumping station, the computational fluid dynamics (CFD) simulation analysis, physical model test, water hammer analysis and structural vibration analysis were used. According to the analysis results, the design scheme was optimized.
