Abstract：The well pipe and well point drawdown is a simple and effective method to drawdown the level of subterranean water.It is normally used in the sandy soil in which the osmotic ratio is 0.5~5 m/d.In this paper,the well pipe and well point drawdown is used to drawdown the level of subterranean water in strong weathering rock stratum.The selection of pump is also discussed.well pipe and well point drawdown;pump;pit;strong weathering rock stratum
