- Abstract:
- At present, there are two design schemes for section drainage pump house in metro area: the conventional co-built pump house and the new built-in pump house, and their applications in Xuzhou and Ningbo were discussed in combination with engineering cases. Hydraulic calculation of the submersible sewage pump, design idea of the pump house scheme and design size of the sump were comprehensively analyzed, and advantages and disadvantages of the two schemes, such as civil construction risk, structural stability, related design professional influence, project investment and later operation and maintenance were compared. Different schemes should be selected according to the actual situation. The new built-in pump house provided a more flexible design for the drainage pump house in urban rail transit section. However, it still needs to summarize and improve the design technology. It was suggested that the design scheme of a new pump house should be avoided as far as possible unless a special section with poor geological condition, rich water and great construction risk of setting up a contact passage was encountered.
