Abstract The invention provides a vacuum preloading single-pump dual-power water-gas separation device and a using method. A first jet device and a second jet device are driven to work through a submersible pump, a vacuum pump and a drainage pump in a traditional water-gas separation technology are replaced, and the water-gas separation effect is achieved. The submersible pump pumps water, the water is sprayed out through the first jet device and the second jet device, vacuum negative pressure is formed in suction chambers of the jet devices, the first jet device pumps the water out through a water outlet of a traditional water-gas separation tank, the second jet device pumps air out through an air outlet of the traditional water-gas separation tank, and under continuous work of the submersible pump, the water-gas separation vacuum preloading foundation reinforcement effect is achieved. The structure that the submersible pump is integrated with the two jet devices to replace the vacuum pump and the drainage pump is ad
