[0002] Nowadays, in areas with pipeline equipment, such as water rooms or toilets, it is often necessary to make pipeline shafts to hide the pipeline equipment. The outer facade of the pipeline shaft should be inlaid with the same surface material as the surrounding walls, and inspection ports should be left at the locations where the pipelines are controlled or the equipment is connected. If the location of the inspection ports and the connection structure and surface decoration measures of the inspection doors are inappropriate, it is very easy to cause pipeline devices to be difficult to inspect and replace, to be easily damaged by repeated opening, and the space design to lack an overall aesthetic. After sufficient research and analysis, it was found that the main reason for the above phenomenon is that the inspection doors on the inspection openings are usually purchased finished products. Since the sizes of the finished products are relatively fixed, it is difficult to combine the functionality and decorative aesthetics of the positions reserved, and thus it is unable to meet the overall inspection needs. In addition, the opening components of the finished inspection doors have low structural strength and are prone to deformation, falling, and falling off. Moreover, the surface materials on the finished inspection doors cannot be consistent with the surface materials of the pipe shaft and the wall, thus destroying the overall decorative effect of the wall. Therefore, the inspection opening position is unreasonable, the inspection door connection structure is unreliable, and the decorative measures are improper, which can easily lead to pipeline devices that are difficult to inspect and replace, easy to be damaged by repeated opening, and the space design lacks an overall aesthetic.
