Underground civil defense engineering wire pipe with wearing welded steel pipe, by the "People's Air Defense Basement Design Code" 7.4.3 strong provisions.
According to the "People's Air Defense Basement Design Code" stipulates:
Air defense basement has "anti-nuclear weapons, conventional weapons, biological and chemical weapons" and other requirements, electrical piping in and out of the air defense basement must be handled in line with the project's protective, airtight function, these parts of the protective, airtight is quite important, when the piping is not sealed tightly, it can be used to protect the air defense basement. When the pipeline seal is not tight, it will cause air leakage, leakage of poison and other phenomena, and even filtration ventilation indoor form of overpressure.
Pre-embedded pipe in the protection of airtight partition wall should be based on the different levels of engineering resistance, to take the appropriate measures to protect the airtight. Pre-embedded pipe in the airtight wall to take airtight blocking measures.
Through the outer wall, airside wall, protection and confinement partition walls and confinement partition walls of the electrical pre-embedded pipeline should be selected wall thickness of not less than 2.5mm hot-dip galvanized steel pipe. In other parts of the pipeline can be in accordance with the relevant ground building design specifications or provisions of the choice of pipe.
Note: underground human defense project is to protect the wartime personnel and material shelter, people's air defense command, medical rescue and construction of separate underground protective buildings, as well as combined with the ground building construction can be used for wartime air defense basement. People's air defense project is to guard against sudden attacks by the enemy, effective sheltering of personnel and materials, to preserve the war potential of the important facilities.
Expanded information:
Underground air defense project design points:
Air defense basement professional team project, personnel shelter project design, should be the area of shelter according to the "specification" table 3.2.1-2 of the "area standard". "Area standard" to determine the number of sheltering personnel or equipment, not allowed to arbitrarily raise the "area standard", resulting in the number of sheltering personnel or equipment to reduce the width of entrances and exits, protective equipment and wind, water and electricity professional design parameters on the small side, to meet the actual needs of wartime.
Personal defense materials library project should be based on the storage of food, materials, materials, the minimum width of the entrance and exit door 1.5m, for the construction area of more than 2000m protection unit of the main entrance and exit of the materials library should be considered into the forklift, the design drawings should be clear on the vehicular access, the width of the vehicular access to meet the requirements of the passage.
Air defense basement using pile foundation and according to the characteristic value of single pile bearing capacity design, the pile should be counted into the upper wall, column incoming nuclear dynamic load load combination value to check its strength; air defense basement walls, columns should be required by the "norms" counted into the upper building weight and dynamic load load combination value check its strength, piles, walls, columns and so on should be according to the "norms" to check its strength, piles, walls, columns and so on should be according to the "norms". The "code" should be considered in accordance with the provisions of the strength of the material to improve.
