[0002] ‌‌With the development of domestic independent research and development technology, a series of functional rooms with special requirements have been born according to demand. Such functional rooms are also quite different from conventional walls, such as explosion-proof walls, explosion-proof doors, explosion-proof ceilings, etc. The explosion-proof wall is a specially designed wall structure that is designed to quickly release pressure and energy when an explosion occurs to protect the safety of buildings and personnel. It is usually installed near flammable and explosive areas or in places for storing, producing, and handling explosives. The main purpose of the explosion-proof wall is to guide the destructive force generated by the explosion to a preset safe area through specific design and material selection, so as to reduce damage to the main building structure and the surrounding environment.‌ ‌The main problems in the construction of explosion-proof walls include difficulties in material selection, complex construction technology, inconsistent design standards, difficulties in maintenance and inspection, cost control, and safe operation problems during construction. ‌Explosion-proof walls require materials that can withstand a certain amount of pressure and quickly release pressure in the event of an explosion. The selection of such materials is demanding and costly. The construction of explosion-proof walls requires strict process control, professional construction technology and equipment, and the construction process is complex and time-consuming. The design standards for explosion-proof walls in the market are inconsistent, resulting in differences in design and construction, which affects the quality and safety of the project. The construction cost of explosion-proof walls is high, including material costs, labor costs, and equipment costs, which puts pressure on the project budget.
