Description

Technical Field

[0001] The utility model relates to the technical field of casing plugging, in particular to an adjustable casing hole sealing structure. Background Art

[0002] When civil air defense casing is used in the construction of civil air defense closed exterior walls, all pressure measuring tubes, sampling tubes and compressed air pipes that pass through the wall are directly poured into the closed wall as shown in the figure below. No holes should be reserved for installation. The closed disk of the pipeline should be selected according to the thickness required by the specification, and the closed disk should be welded tightly without any gaps and pinholes, combined with sealing to prevent leakage; when pouring the civil air defense casing, in the existing technology, bolts and flange blind plates are used for sealing before construction. After the mold is removed, the concrete at the connection between the casing mouth and the flange blind plate needs to be broken and re-covered to meet the quality requirements, which increases the working time and generates additional production costs. At present, there are many sizes of civil air defense casings, and the corresponding hole diameters are different. Therefore, it is more troublesome to seal the holes corresponding to each civil air defense casing during the construction process, and the construction flexibility is poor. Utility Model Content
