Abstract:
In the paper, the experience and lessons drawn in the design and construction of the pumping stations of the shieldbored running tunnels in Beijing are summarized and the following suggestions are made: 1) If possible, the cover depth of the pumping stations should be appropriately reduced so as to minimize the difficulty in the construction of the pump stations; 2) In waterrich ground where only deephole grouting is made, there is great water/sand inflow risk in the construction of the pumping stations, therefore artificial freezing or ground surface dewatering should be made as far as possible; 3) Deephole grouting may be used as the final optimized countermeasure.
Key words: Beijing Metro, shieldbored running tunnel, drainage system, pump station, deephole grouting
