Analysis And Design Of Fire Protection System For A High-rise Building

In recent years,with the rapid development of the social economy,the urban population has also grown dramatically,causing land resources to be tight.Building high-rise buildings and super high-rise buildings has become an important means to solve the urban land resource shortage,and has become a symbol of the rapid development of the city.As a result,high-rise buildings have sprung up.Although high-rise buildings have brought a new working and living environment to human beings,they have also brought a new problem to mankind: the prevention of high-rise building fires and the effective fire-fighting problems.Therefore,the design and optimization design of the fire protection system for high-rise buildings is very important.The automatic sprinkler system is economical and practical,has a simple composition principle,reduces manual intervention and duty,and has a high success rate in the early stage of fire,which can well protect personal safety and property safety.This system is very popular among industrial and civil buildings and has been widely used ever since.This paper compares and analyzes the way of fire water supply system,solves the problem of overpressure in fire water supply system,and completes the hydraulic calculation of fire hydrant water supply system.This paper focuses on the composition and working principle of the automatic sprinkler system,analyzes and compares its control methods,and completes the relevant hydraulic calculations.It provides a theoretical reference for design and engineering personnel in actual design and construction.As the core component,the fire pump determines the success or failure of fire fighting.Through analysis,this paper selects the programmable controller(PLC)as the controller of the fire pump.In order to improve the reliability of the equipment,the monitoring ability of the online fault,and the automation level,the system has added the functions of regular active and standby mutual investment and periodic automatic testing.Improve the reliability of the operation of the fire linkage control system.Taking a high-rise building project as an example,the paper combines theoretical research and applied research to study and optimize the automatic sprinkler system,fire hydrant system,water supply system and control method of the high-rise building fire protection system.The design of fire protection system for high-rise buildings provides a certain reference to achieve the purpose of more perfecting the design of fire protection system for high-rise buildings in China.Through the research of this subject,we have the following understandings of the relevant design specifications for fire protection systems for high-rise buildings in China:1."Fire Code for High-Rise Civil Building Design"(GB50045-2005)and "Code for Fire Protection of Building Design"(GB50016-2012)are based on the fire prevention policy of "prevention first,anti-disintegration",clearly defining the fire protection design and fire management of China's buildings.The requirements summarize the practical experience of fire protection design in China's buildings,extensively solicit opinions from relevantdepartments and units,and refer to the relevant norms of developed countries,with strong versatility and comprehensiveness;2.There are standard inconsistencies in the Code for Fire Protection Design of High-rise Civil Buildings(GB50045-2005)and the Code for Fire Protection of Building Designs(GB50016-2012).For example,the high and multi-level division standards for residential buildings are not uniform;3.In the "Code for Fire Protection Design of High-rise Civil Buildings"(GB50045-2005),the requirements for the setting of fire-fighting and rescue facilities are not clear enough;there are some requirements for fire protection design for fire-fighting water supply systems,indoor and outdoor fire hydrant systems,etc.;4.During the design process,some designers have not paid enough attention to the fire protection of high-rise buildings,resulting in neglecting some hard standards.
