Rapid dewatering structure for foundation pit of underground station

The utility model discloses an underground station foundation pit rapid dewatering structure which comprises a dewatering pipe, a filtering and collecting device used for filtering and collecting underground water, a water pumping device and a driving device. The downcast pipe is simple in structure and reasonable in design, underground water in the stratum around the downcast pipe is filtered and collected by arranging the filtering and collecting device, and the situation that the underground water flowing into the water collecting cavity contains a large number of impurities is avoided; the water pumping device is arranged to pump underground water in the water collecting cavity, the underground water is filtered again through the filtering pipe when the water pumping pipe is used for pumping the underground water in the water collecting cavity, the water pumping pump is prevented from being blocked, normal work of the water pumping pump is guaranteed, and then the dewatering efficiency of the dewatering s
