Abstract: Through the example of Hangzhou Olympic Sports Center project, based on the analysis of construction period and flow balance, the configuration technology of hydraulic and earth-moving machinery both on site and off site are summarized, when a deep and large foundation excavation is excavated by pumping and flushing. Engineering practice show that through reasonable hydraulic machinery configuration, the effect of saving energy, protecting equipment, reducing cost and increasing efficiency can be achieved.
