When there is a fire, it is difficult to play its due role; Third, the safety exit is congested.
At present, Chinese residents’ understanding and understanding of fire protection is relatively weak, After a fire, residents’ blind escape behavior is relatively serious, and scientific self rescue and fire-fighting skills are very lacking.
Requirements for fire protection of high-rise buildings in high-rise buildings, the density of residential population is large.
Strengthen the publicity of fire prevention, water supply and drainage.
In order to control the fire in time, it is necessary to formulate a scientific and effective fire water supply and drainage system to improve the ability of fire extinguishing.
The fire water supply and drainage system in residential buildings plays an important role in fire protection, It plays an important role in safeguarding the interests of residents.
The space and area of high-rise residential buildings are relatively crowded.
In recent years, the number of high-rise residential buildings in China has gradually increased, followed by reports of high-rise fire accidents.
Many owners pile up sundries in the corridor, causing the corridor to be congested, making it more difficult for the owners to escape and causing more losses; Fourth, the fire water supply is relatively difficult.
At the same time, in order to improve residents’ awareness of fire safety, efforts should be made from the following aspects: 1.
Improvement measures for fire water supply and drainage system of high-rise residence domestic water and fire water supply of high-rise residence should be set separately, and fire water supply should ensure two-way water supply.
At present, the fire water supply and drainage problems of high-rise residential buildings are more prominent, including: first, the architectural design is unreasonable and the corresponding fire-fighting facilities are not arranged; Second, the fire-fighting facilities and equipment are relatively old and often fail.
For the drainage system, we should actively seek the cooperation of residents, let residents check by themselves or assisted by property management personnel, so as to avoid blockage.
In the process of daily use, pay attention to their inspection to reduce the occurrence of mechanical faults.
They should recognize that the safety of residents is the primary goal.
Relevant construction enterprises should combine the fire water supply and drainage system with the automatic fire alarm system.
During the use of high-rise residential buildings, the property management company shall regularly check whether the fire water supply facilities can work normally to ensure that they always maintain a normal working state.
In reality, its existing problems are also prominent and need to be improved by relevant departments.
They should not reduce the function of fire water supply and drainage due to other pipeline or equipment factors.
If the static pressure requirements cannot be met, a pressure stabilizing pump shall be set.
The places where they are set are mainly elevator halls, stairs, walkways and other public parts.
In the process of work, they should be good at summarizing, find deficiencies in work and correct them in time, so as to make fire water supply and drainage more reasonable and effective.
When the alarm system receives the fire signal, it can start the water supply and drainage system in time, so that it can supply water in time and extinguish the fire at the first time, This modern fire alarm system has also been widely used.
Class I high-rise civil public buildings shall not be less than 0.10MPa.
When there is a fire, it will cause very large loss of personnel and property, which will increase the harm of fire.
In order to ensure the quality of construction, relevant regulatory units should strictly supervise the construction of fire water supply and drainage system, so that the construction standards are fully implemented in accordance with national regulations, In addition, the review of fire water supply and drainage shall be incorporated into the final acceptance work to improve the attention of the construction unit.
3.
4.
The number of casualties in high-rise residential fires can even reach hundreds, resulting in more serious losses, which has sounded the alarm of fire safety to the society and people.
The fire water tanks shall mainly pay attention to the following points: first, the height of high-rise buildings shall be considered when setting the high-rise fire water tanks.
Strictly control the construction of fire water supply and drainage system.
If there are problems, Those responsible will be held accountable.
The limited space is often occupied by parking spaces and various pipelines, so the fire water supply is more difficult.
In the process of construction, regular and irregular inspection system shall be adopted to keep the construction quality at a high level.
The water supply and drainage equipment with problems shall be replaced in time to ensure its use quality.
An effective automatic fire alarm system can also play a very positive role in fire control.
According to the design requirements of relevant equipment, buildings with temporary high-pressure water supply system in building water supply and drainage shall be equipped with fire water tanks.
In the water supply and drainage link, publicity should be strengthened, and relevant departments can bring fire-fighting knowledge and escape skills training to the community, Let residents feel the importance of water supply and drainage and the importance of fire protection, and require relevant units to fully implement the installation and commissioning of fire water supply and drainage, so as to ensure the life safety of residents.
The outlet pipe shall be located below the lowest water level of the high-level fire water tank, and a check valve shall be set to prevent fire water from entering the high-level fire water tank..
Therefore, residents’ fire-fighting awareness should be improved.
Third, the outlet pipe diameter of the high-level fire water tank shall meet the outlet requirements of the design flow of fire water supply, and shall not be less than DN100.
For class I high-rise public buildings, the water volume shall not be less than 36m3, and when the building height is greater than 100m, the water volume shall not be less than 50m ³， When the building height is greater than 150m, it shall not be less than 100m ³。 Second, the setting of high-level fire water tank shall be higher than the fire extinguishing facilities it serves, and its minimum effective water level shall meet the hydrostatic pressure at the most unfavorable point of water fire extinguishing facilities.
Regularly check the fire water supply and drainage system.
5.
Establish an automatic fire alarm system.
In the process of building high-rise houses, construction enterprises are prone to Jerry building.
2.
It shall debug them every quarter, replace the old fire water supply facilities, implement this work to specific personnel, and implement the responsibility system.
In the process of work, relevant design and construction units should increase consideration in this regard.
When the building height is more than 100m, it shall not be less than 0.15Mpa.
