Description
Technical field
The invention belongs to water storage and emergency feedwater technology category, is related to a kind of normal, improper or emergent in city planting ductwork
Feedwater and emergency feedwater under water supply conditions, it is the current emergency shelter in China (public affairs such as park, greenery patches, square, stadiums
Cospace) water storage and the supporting technical method of emergency feedwater.
Background technology
World today's disaster takes place frequently, and there is millions of people in the annual whole world, by from earthquake, hurricane, flood, arid etc. from
The influence of right disaster, in addition to these natural calamities, the man-made disaster such as Public Health Emergencies, terrorist incident, war,
All directly threaten the safety of life and property of the mankind.Therefore, think of danger in times of safety, provide for a rainy day, build a number of meet an urgent need and keep away
Difficult place (including shelter constructions and place of taking refuge), just seem particularly there is an urgent need to.Rationally distributed, multiple functional emergency-sheltering
Place, disaster affected people can be made to be succoured in time, effectively treat and make proper arrangements.
Emergency shelter refers in the accident hair such as the issue of the warning information such as earthquake, hurricane, flood, arid or war
After life, town dweller avoids the coming trouble, life temporarily and the temporary transient place of hedging.Typically build in flat sky of certain scale
Spacious field ground, such as park, public lawn, square, sport field；It may also be arranged on and meet certain design requirement, a set pattern
The shelter constructions or the underground space (containing civil defence engineering) of mould.Emergency water supply, emergent Peng Su, emergent lavatory are provided with emergency shelter
All kinds of emergency function areas such as institute, emergency shower, contingency management, emergency lighting, supporting corresponding automatic rescue facilities and equipment, deposit
The emergency materials such as food, medicine.
With continuous expansion and in-depth that countries in the world recognize to city's essence, Safety Cities, the theory in flexible city are got over
More to be recognized by people, the emergency shelter construction of natural calamity and accident is defendd constantly to be put on the agenda,
In China big and medium-sized cities, the construction of emergency shelter is increasingly popularized.By taking Jiangsu Province as an example, end the first half of the year in 2015, the whole province
Building together has center and fixed refuge 423, and the gross area reaches 35,100,000 square metres, and design seating capacity reaches more than 3000
Ten thousand people.So huge service population, no water storage and emergency feedwater device are inconceivable with water feeding method, and the present invention is just
In order to solve this problem, realize this target and carry out.
Meanwhile current Chinese society is also an open society, rally, large-scale recreation increase, these are accepted
Rally, the square of large-scale recreation, stadiums etc., also there is an urgent need to provide the emergent adequate and systematic service such as emergency feedwater.
The content of the invention
The water storage and emergency feedwater device and water feeding method that the present invention is developed based on the principle of plain polder area, the device are put down
When be Municipal pipe network part, in emergency situations, by emergent conversion, emergent life, doctor can be provided rapidly
Treatment water, meet the needs that a large amount of crowds gather.
The resource of water supply part that the present invention is relied on, it is the life that the city planting ductwork of the public spaces such as emergency shelter provides
Drinking water living.The size of water storage device storage water, power and the emergency shelter of water supply capacity accept the emergent of service
Number of taking refuge mutually is coordinated.Emergent water storage device water supply capacity should meet the life that the temporary phase maintenance of more than 3 days is survived substantially
With the water consumption of water and health care rescue water, according to including staff, emergency management and rescue personnel and emergency-sheltering number etc.
In interior crew 80-100 (L/ people d) for each person every day standard, total water consumption is calculated.Water storage device concentrated setting or scattered can be set
Put, and the appropriate to the occasion distribution by Emergency water supply ensuring target of scattering device carries out cooperative arrangement.
The present invention be exactly for usually water storage, calamity when quick Emergency water supply design.
A kind of buried water storage and emergency feedwater device, it is characterised in that including：Water tank (1), water inlet pipe (2), water outlet
