setting a gas pressure value of the one-way valve, and requiring that the gas flow direction of the one-way valve only flows from the inside to the outside of the single-pile foundation, so that the one-way valve automatically opens a valve to discharge gas in the single-pile foundation when the gas pressure in the single-pile foundation reaches the gas pressure value according to the set gas pressure value, the pressure in the single-pile foundation is reduced, and the gas pressure in the single-pile foundation is controlled to meet the standard requirement.
7. The method for automatically discharging the internal gas of the single pile foundation of the offshore wind turbine generator system according to claim 6, wherein the one-way valve is subjected to a pressurization test, and the method comprises the following specific operations:
sleeving an uninflated balloon at the air outlet of the one-way valve, fastening the balloon and the air outlet of the one-way valve, and inflating and pressurizing the interior of the single-pile foundation through a test hole by using pressurizing equipment; if the inner pressure of the single-pile foundation reaches the set gas pressure value of the one-way valve, the balloon starts to inflate and expand, the test succeeds to prove that the single-pile foundation is sealed to be qualified and the one-way valve meets the requirements, the pressurizing equipment is closed, the experiment is stopped, and the balloon is taken down; if the balloon is not expanded, whether the seal is qualified or not is checked, or whether the one-way valve is intact or not is checked, and the pressurization test is carried out after the problem is eliminated until the test is successful.
8. The method as claimed in claim 6, wherein the rubber hose is fixed on the wall of the tower cylinder and the door of the tower cylinder, and the rubber hose is required to be routed so as not to hinder the operation of workers and the opening and closing of the tower cylinder door.
