The distance between the drainage pipes of the secondary drainage system and the ground is 10 centimeters, and the distance between the drainage pipes of the tertiary drainage system and the ground is 20 centimeters.

The liquid level sensor is connected with the electric controller through the wire, and the electric controller is respectively connected with the submersible pump and the water pump through the cable, and the electric controller is provided with a microprocessor.

The water pumps are high-power water pumps, the number of which is not less than 3.

The first-level drainage system is evenly arranged on the ground of the underground parking lot, and the second-level drainage system and the third-level drainage system are arranged in every corner or a position that does not affect parking.

The beneficial effect of the utility model is that the structural design is reasonable, the drainage speed is fast, the drainage effect is good, safe and reliable, economical and applicable, and easy to be popularized and used on a large scale. When rainwater enters the underground parking lot, the rainwater will first be drained through the first-level drainage system; when the first-level drainage system cannot meet the drainage needs and the water level exceeds 10 cm, the rainwater will be drained through the second-level drainage system, and the rainwater will enter the well. When the height of the liquid level sensor is exceeded, the submersible pump will automatically start through the electrical controller to quickly drain the water in the well; when the secondary drainage system cannot meet the drainage needs and the water level exceeds 20 cm, the rainwater will be drained through the tertiary drainage system. The rainwater enters the large-capacity storage tank. When the water level exceeds the height of the liquid level sensor, multiple pumps are automatically activated through the electrical controller to quickly discharge the water in the storage tank; when the water level exceeds 20 cm, three drainage pumps The system drains at the same time, the drainage speed is fast, safe and reliable.
