Negative pressure drainage system and drainage method
The invention discloses a negative pressure drainage system and a drainage method. The drainage system comprises a vacuum valve pit, a vacuum pot, a first valve, a water pumping pipe, a vacuum pipeline and an air inlet pipe, wherein a first end of the water pumping pipe extends into the bottom of the vacuum valve pit; a second end of the water pumping pipe is connected with the vacuum pot via the vacuum pipeline; the first valve is arranged between the vacuum valve pit and the vacuum pot; a first end of the air inlet pipe is communicated with the water pumping pipe; a second end of the air inlet pipe is communicated with the atmosphere pressure; an interface between the air inlet pipe and the water pumping pipe is arranged over the second end of the water pumping pipe; water flows in the vacuum valve pit enters the vacuum pot and decreases to a lower limit of a preset liquid level; and after preset time, the first valve is closed. Realistic foundation is laid for theoretical research on the negative pressure drainage system; and an existing system can be simulated, so operation stability can be improved and daily maintenance and management can be facilitated.
