| Abstract: | The deep excavation was supported by the structure of no-sand concrete pile and priestess earth anchor. The groundwater of the pit-outside was processed by the water-proof curtain which was composed of the no-sand concrete piles, jet grouting piles and priestess tieback, and one of the pit-inside was dewatered by the well in the sustaining layer-cobbles and fine gravels a series of measure of etc, that guaranteed the safety of the peripheral building, and gave certainly draw lessons to complicated environment next the city engineering construction from the value. |
