A protective device for a baseplate of a water conveyance canal at high groundwater table is fixedly arranged at the bottom of a water conveyance canal longitudinal slope and comprises a housing, a one-way valve and a cover plate, wherein the cover plate is fixedly arranged at the bottom of the water conveyance canal slope; water passing holes are formed in the cover plate; one end of the housing is open, and the open end is fixed with the cover plate; a water storage cavity is formed between the cover plate and the housing; the one-way valve is mounted in the water storage cavity, and underground water flows into the water storage cavity in one direction; and the difference between the elevations of the protective device and the base plate of the water conveyance canal is larger than zero. After the protective device is arranged at the bottom of the water conveyance canal slope, the effect of automatic closure without increasing water head loss during water conveyance is achieved; and the one-way valve is automatically opened when the groundwater table is higher than the water level of the canal, so that uplift pressure, caused by high groundwater table, on the baseplate of the canal is reduced.
