Vacuum pump water-discharging device suitable for tunnel excavation

The invention relates to a vacuum pump water-discharging device suitable for tunnel excavation. The vacuum pump water-discharging device comprises a vacuum pump, wherein the vacuum pump is provided with a water inlet pipe and a water outlet pipe, and the water inlet pipe is communicated with a water suction and filtering assembly through a connecting pipe. The vacuum pump water-discharging device has the advantages that the vacuum pump water-discharging device can discharge out seeped water in a tunnel in time; the problems of poor water-discharging effect and time and labor waste of an existing submerged pump water-discharging device for tunnel excavation and water pump burnout due to poor heat dissipation are solved.
