1, the principle of people's air defense project construction. People's air defense project construction should follow the "unified planning, the amount of focus, peace and war, quality first" principle.
2, building to build air defense basement. The People's Air Defense Law stipulates that "new civil buildings in the city, in accordance with the relevant provisions of the state to build a basement that can be used for air defense in wartime."
State regulations: a class of key protective cities (provincial capitals), new civil buildings of more than 10 floors or foundation depth of more than 3 meters, should be built according to the first floor of the ground floor construction of air-raid basement, new construction of other civil buildings, the total floor area of more than 2,000 square meters on the ground, according to the ground floor area of 4-5% of the centralized construction of the air-raid basement; new residential complexes, development zones and economically important. Residential districts, development zones and important economic target areas of civil buildings, according to a one-time planning of the total ground floor construction area of 4-5% of the centralized construction of air defense basement.
The construction of air defense basement in combination with civil buildings is to improve the city's air defense against destruction, preserving the potential for war and the need for living forces. The basic function of the air defense basement is to defend the enemy's sudden air attack, to protect the safety of people's lives and property. The air defense basement can utilize the protective ability of the superstructure, and it has better protective effect against the direct hit of aerial bombs, early nuclear radiation and nuclear fallout. Air-raid basements can also be used to provide engineering support for the troops and militia of the city to maneuver and transport forward and backward, and to fight tunnel battles, barricade battles, and alley battles, and to become an important supplement to the engineering security of urban defense operations. The construction of underground air defense rooms will play an important role in winning the struggle against air raids and urban defense operations. In addition, the construction of air defense basement in combination with civil buildings, but also to enhance the stability of the building, improve the ability of the ground building disaster prevention and resistance to destruction and increase the use of the building area, the need to save land.
3, human defense works are different from ordinary basement. Ordinary basement is built to stabilize the ground building or to achieve a certain purpose, there is no protection level requirements. Air-raid basement is specially designed according to the protection requirements of the air defense project. The difference is:
(1) the human defense basement roof, side walls, floors are thicker than ordinary basement, solid, in addition to load-bearing and a certain resistance to shock waves and conventional bombs blast wave capability.
(2) the human defense basement structure is closed, there are filtering and ventilation equipment, chemical and biological warfare agents, equipment and capabilities, while the ordinary basement does not.
(3) The human defense basement has outdoor safe entrance and exit, while the ordinary basement does not.
(4) The seismic capacity of the human defense basement is better than the ordinary basement. Necessary reinforcement and remodeling of the ordinary basement in wartime can also make it have a certain degree of protective effectiveness.
4, residents should care for human defense works, protection of human defense facilities. The People's Air Defense Law provides that "any organization or individual is prohibited from destroying or encroaching on the people's air defense facilities" and "shall not be affected by the use of air defense works or reduce the protective capacity of the operation". Residents should understand the important role of air defense projects and facilities in air defense and disaster prevention, and care about the integrity and maintenance of air defense projects and facilities, and do the following:
(1) Do not discharge waste gas, waste water, waste residue, etc. into the air defense projects;
(2) Do not produce or store flammable, explosive, poisonous, radioactive or corrosive substances in the air defense projects.
(3) Not to block the entrances and exits of the works, vents, and not to dismantle, use or relocate the alarm equipment of the human defense privately. Users of civil defense works in peacetime should undertake to complete the tasks of peace and war conversion within the specified time. Do not occupy or mixed use of human defense communication frequency and air-raid warning signals, do not abuse the human defense signs.
(4) If you find any damage to human defense facilities, you should stop it immediately and report it to the departments of human defense.
5, the relative safety of the city under the conditions of modern air attack. Since modern air attack mainly strikes important military, political and economic targets with precision, relatively safe places may be:
(1) Pure temples, churches, hospitals, kindergartens, schools, farms, parks, and ordinary bungalow residential areas.
(2) Important targets 100-200 meters away from the place; suburbs, countryside, mountainous areas; secondary disasters can endanger the direction of the upper wind and water; gas stations, oil storage tanks and dangerous goods warehouses more than 1000 meters away from the place.
(3) human defense works and evacuation area.
6, people's air defense construction project approval authority. Large-scale construction projects by the national people's air defense authorities for approval; small and medium-sized construction projects by the people's air defense authorities of the people's governments of the provinces, municipalities and autonomous regions for approval; sporadic projects by the people's air defense of the people's air defense of the key city people's air defense authorities for approval.
7, should be built air-raid basement construction project approval process. Should build air-raid basement construction projects, without the approval of the people's air defense department in charge of the examination and approval, construction, fire and other departments can not handle the relevant procedures. Indeed, because of geological conditions can not build air-raid basement projects, by the people's air defense departments in charge of the examination and approval, according to the provisions of the payment of land construction fees, specific charges by the provinces, autonomous regions and municipalities directly under the central government price authorities in conjunction with the same level of finance, the people's air defense departments in accordance with the local cost of air-raid basement development. In addition to the national provisions of the exemption program, any department or individual shall not be approved to reduce or waive the construction fee.
