4. Whether the material of the air defense door meets the design and functional requirements.

5. The perpendicularity of the embedded steel frame on the door frame wall is allowable deviation of 2-5mm. When installing a prefabricated steel frame, bending is not allowed.

6. The concrete of the door frame wall should have the stiffness and strength expected by the design, especially the concrete within the angle steel of the door frame should be dense to achieve the design.

7. After the concrete construction is completed, the door frame on the wall of the civil air defense air defense door frame is in the expected stage of work and its resistance requirements. It should be correct, the frame surface should be flush with the concrete wall, the frame surface should be vertical, and the front frame should be flat and not warped.

8. The sealing tape and sealing ring on the door leaf should be complete and in normal working condition, and the ammonium chain seat should be located on a uniform plumb line.
