| Abstract: | Abstract：Foundation pit of a project is large and deep and encounters special water-bearing stratum, so dewatering process is required. After comparison of various construction schemes and model calculation, it is determined to set decompression dewatering well in the foundation pit and water level observation well and inverted well outside. The dewatering well uses patented technology Johnson filter and wire filter, which realize favorable dewatering effect. Water level in the foundation pit is under effective control and excavation is carried out smoothlv_ |
