What are the requirements for setting up fire hydrants in high-rise buildings?
The hydrant hydrant should be 1.10M from the ground, and the direction of the water outlet should be downward or perpendicular to the wall of the hydrant.
Hydrant hydrant water pressure should not be greater than 1.00MPa, when greater than 1.00MPa, you should take sub district water supply system. When the outlet pressure of hydrant is greater than 0.50MPa, measures should be taken to reduce the pressure.6, fire hydrant should use the same model specifications. Hydrant hydrant diameter should be 65mm, the length of water should not exceed 25m, nozzle caliber should not be less than 19mm.
The fire hydrant spacing should be calculated, and the high-rise building should be no more than 30m, the podium should not be greater than 50m.
1, fire hydrant should be located in the aisle, near the stairs and other obvious easy to use the place, fire hydrant spacing should ensure that the same floor any part of the two fire hydrant water column, full water column at the same time.2, fire hydrant water column full water column should be determined by hydraulic calculation, and the building height is not more than 100m of high-rise buildings should not be less than 10m; building height more than 100m of high-rise buildings should not be less than 13m.
