Test method for watertight performance test of flood-proof protective air-tight door

A watertight performance test method for a flood-proof protective air-tight door comprises the following steps: step 1, designing a door body, and designing a test cabin according to the size of the door body; 2, a door body is manufactured, a test cabin is built, and the door body is installed on the test cabin; 3, carrying out at least one first air tightness test, at least two water logging tests and at least one ending air tightness test on the door body through the test cabin; and step 4, generating a test report according to the air tightness test and the water logging test. According to the invention, air tightness and water logging tests can be carried out on the flat open type flood-proof protective air-tight door through the test cabin, water head overestimation or water head pressure can be adjusted according to test requirements, test requirements under various different application scenes are met, and the test cabin has the advantages of reasonable structural design, reliable test data and the li
