Zusammenfassung:The utility model discloses an underground structure decompression drainage anti-floating device which comprises a base, a supporting seat is fixedly connected to the end face of the top of the base, a soil filling pit and a collecting pit are formed in the supporting seat, a contact assembly is arranged in the collecting pit, and the contact assembly is used for connecting the soil filling pit with the collecting pit when much water is stored in the collecting pit. And the contact switch is controlled to start to pump water from the collection pit. The device has the advantages that when groundwater is too much, pumping of water in the filling pit cannot be guaranteed through pumping of the water pumping pipe, at the moment, under the buoyancy of water, the floating plate is driven to float along the water surface, the fixing plate moves to drive the contact switch to make contact with the covering plate, the multiple water pumps are started, and the filling pit is filled with water. Liquid in the collecting
