[0002] Nowadays, construction projects are booming, and various large-scale buildings are constantly being built and put into use. Now most buildings are equipped with civil air defense projects. Civil air defense projects are mostly in the form of underground garages. Civil air defense doors, blocking doors, lighting, ventilation, water supply and drainage, communication networks and other hardware required for wartime shelters are installed inside. When building civil air defense projects, it is necessary to pour a concrete protective layer. However, the concrete protective layer currently used generally has a low structural strength and cannot withstand strong external impact during use. In addition, the overall structural strength is low, and external noise will also affect people indoors. Utility Model Content
