Description

Technical Field

[0001] The utility model relates to the technical field of plugging devices, in particular to a water-tightness test casing plugging device. Background Art

[0002] The closed water test is also called the water storage test. It needs to be filled with water and the water volume should be sufficient. The water storage depth of the water storage test should not be less than 20 mm, the water storage height is generally 30-40 mm, and the water storage time should not be less than 24 hours. Move downstairs to observe whether there is any water leakage on the roof downstairs. No water leakage is considered qualified. This test is generally performed on the roof, bathroom or room with waterproofing requirements. In the early stage of the water storage test, you should check downstairs once every 1 hour, and in the later stage, check downstairs once every 2-3 hours. If water leakage is found, the water storage test should be stopped immediately, and the waterproof layer should be re-performed. After the treatment is qualified, the water storage test can be carried out again.

[0003] Currently, when conducting a water-tightness test, it is necessary to seal the pipes or reserved pipe holes inside the building to prevent liquid from leaking along the pipes or reserved pipe holes when water is stored. After the water-tightness test, the plugging head needs to be removed from the inside of the pipe or reserved pipe hole. However, since the liquid will increase the resistance between the plugging head and the pipe or reserved pipe hole, it is more difficult to remove the plugging head.

[0004] Therefore, in order to solve the above problems, we propose a water-tight test casing plugging device. Utility Model Content
