Optimal Design Of Fire Supply System For High Rise Buildings

For the design of fire water supply in high-rise buildings,because of the large pressure of water supply,the strong safety measures of the pipeline and the wide range of water supply technology,the fire is difficult to find in the high-rise building,the fire spread quickly and the people are evacuating.The characteristics determine that the design can not be considered according to the general building.In this paper,the high-rise building fire water supply system as the research object,its optimization research,to ensure maximum safety of high-rise buildings.The paper analyzes the design deviation of fire water tank in the fire water supply design of high-rise buildings,the allocation of high fire water tank can not provide sufficient water pressure,the number of indoor fire hydrant is not clear,and the selection of fire water pump is selected.Then,the correct calculation of the two-way water supply and rational determination of the fire water tank and the high-rise building is put forward.The setting of hydrant and the number of indoor hydrants,and timely updating of fire water use.Connecting with the practice of water supply design,optimizing the system oriented,taking the water supply mode of high-rise buildings as the breakthrough point,and comparing their differences to choose accurately.According to the characteristics of different high-rise buildings,the water supply mode which is the most suitable for water use is chosen to ensure the safety and reliability of the system,and any problem in its link will bring unpredictable loss.Secondly,the economy is discussed from the selection of the indoor fire hydrant equipment and the determination of the parameters of the automatic sprinkler system in order to reduce the cost,the cost and the maintenance cost of the system itself.Through the study of reference literature at home and abroad,the author then optimizes the fire water supply system of high-rise buildings,making the fire water supply system more reliable,safer and more economical in the high-rise building,and achieves the best effect in the engineering example.This paper takes a high-rise dormitory building in Hefei as an example.According to the law and characteristics of the water use of the high-rise dormitory building,the theory is integrated into practice.The optimization analysis is made from the overall stability,the partition selection,the transfer water tank and the pump and so on,and the optimal water supply scheme is calculated with the mathematical model.This paper expounds the problems that designers should master and solve the high-rise building fire water supply design.In order to improve the safety awareness of fire protection design and eliminate the hidden danger of fire water supply network,it is suitable to design and plan the pressure relief valve and automatic sprinkler system to realize the sustainable development of the high-rise building.
