The limit application height of'one pump to the top'water supply mode is discussed,and the concept of'temporary high pressure gravity fire water supply system'is put forward.The feasibility of'temporary high pressure gravity fire water supply system'is studied,and a relatively economical and reasonable design scheme of fire water supply system is discussed for super high-rise buildings or buildings below 170 m.The'temporary high pressure gravity fire water supply system'cancels the independent fire booster pump set in the low area,and the fire system in the low area is supplied by the gravity of the high tank,which simplifies the system form and improves the economy of the system,and has positive significance for the optimization of fire water supply system of such buildings.
