Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a foundation pit drainage device. Background Art

[0002] Municipal engineering projects often involve excavating foundation pits underground. However, rainy, snowy weather or underground seepage will cause water to accumulate in the foundation pits. If there is too much water in the foundation pits, it may cause the foundation pits to collapse. Therefore, a water pump is usually used to pump water out of the foundation pits.

[0003] When the foundation pit drainage device is in use, water is usually sucked in from a high place by extending the water absorption component into the foundation pit to discharge the accumulated water in the foundation pit. Since the existing foundation pit drainage device cannot adjust the water absorption component, it is usually of fixed height and length, which is not convenient for working under a foundation pit with a large slope or a deep height. In addition, the hose is usually manually wound and stored during and after the work, which wastes time and delays the construction progress. Therefore, it is necessary to solve the problem that the existing foundation pit drainage device cannot adjust the water absorption component, is not convenient for drainage on a foundation pit with a large slope, and is not convenient for winding an overly long hose.
