1.
The technique of pipe well for lower (obstruct) water is to set pipe well for lower water around deep foundation pit and draw water by phreatic water pump,thus can depress water pressure of underwater and lower water level,avoid great gush water in the process of construction of deep foundation pit and emerged harm of quicksand,and ensure the construction finish successfully.
管井降(截)水技术是通过在深基坑周围设置管井降水井,利用潜水泵抽排地下水,使地下承压力水减压后再降低地下水位,避免深基坑施工过程中大量涌水,并产生流砂危害,确保深基坑顺利施工。
