杂填土含水层大型深基坑的降水方法

杂填土含水层大型深基坑降水，应根据场地的施工环境，采用人工挖掘辐射降水井、引水入基坑的降水方法，并将排水系统修筑在连梁上面，这样可取得良好的降水效果。

Water Draining Method of Large-scale Deep Foundation Pits in Water-bearing Horizons of Miscelaneous Fill

he paper focuses on the discussion of the water draining method of the large-scale deep foundation pits in the water-bearing horizons of miscelaneous fill. Based on the working conditions of high-building construction site, some radiating dewatering wells should be dug around the foundation pits, the drainage system is immediately building on the post-and-lintel, the water from the water-bearing horizons of mis celaneous fill is drawn into the foundation pits and drains away, which has a good effect on water drain ing of deep foundation pits in the water-bearing horizons of miscelaneous fill.
