The invention discloses a blanking cap with a one-way drainage function and a vehicle body floor. The blanking cap with a one-way drainage function comprises a blanking cap body and a blanking cap valve element arranged on the blanking cap body. The blanking cap body is provided with a water leakage opening communicated with the inner side and the outer side of a plugging hole, and the blanking cap valve element seals the water leakage opening under the action of the water pressure from the outer side to the inner side and the water leakage opening is opened under the action of the water pressure from the inner side to the outer side. According to the blanking cap with the one-way drainage function and the vehicle body floor, since the blanking cap valve element arranged in the blanking cap body is subjected to different effects of internal water and external water, accumulated water in a passenger compartment can be drained, water outside a vehicle can be prevented from flowing back into the vehicle; and the structure is simple, and the process is easy to achieve.
