[0002] In the field of biopharmaceuticals, especially in vaccine production cleanrooms, biosafety is paramount, and the requirements for cleanrooms are extremely stringent to ensure their safety. Traditionally, cleanrooms do not have a separate equipment and piping layer; all air ducts, water supply and drainage pipes, cold storage, and greenhouse units are placed in the upper technical mezzanine of the cleanroom. This is particularly problematic for vaccine production facilities, which involve numerous processes and complex piping and drainage systems, including pressurized and non-pressurized toxic water, non-pressurized and non-pressurized non-toxic water, and steam condensate pipes. This leads to overlapping and disorganized construction procedures, hindering project timelines. Furthermore, limited space for maintenance and repair increases the difficulty of maintenance and raises safety risks. Utility Model Content
