Description

Self-adaptive underground water drainage control device Technical Field The utility model relates to the technical field of groundwater drainage, in particular to a self-adaptive groundwater drainage control device. Background In the construction and operation of landslide and structures such as piles, spoil areas, roads, buildings and the like, groundwater drainage is important. In order to ensure the safety of the structure, the underground water level needs to be strictly controlled, and the underground water level is prevented from exceeding a set water level control line. Therefore, a water pump which is automatically started and stopped according to the water level is usually arranged, when the water level rises to a certain extent, the water pump starts to drain water, and after the water level drops, the water pump stops, so that the stability of the underground water level is maintained, and the structure is ensured to be in a safe running environment.
