The water cannon of the fire hydrant shall be determined by hydraulic calculation, and the building height shall not be less than 10m for high-rise buildings not exceeding 100mm; High-rise buildings with a building height of more than 100m should not be less than 13m. 3. The spacing of fire hydrants should be determined by calculation, and high-rise buildings should not be greater than 30m, and podiums should not be greater than 50m.
Fourth, the height of the fire hydrant mouth from the ground should be the direction of the water outlet of the fire hydrant should be downward or perpendicular to the wall where the fire hydrant is installed. 5. The hydrostatic pressure of the fire hydrant should not be greater than that, and when it is greater, the zonal water supply system should be adopted. When the water outlet pressure of the fire hydrant is greater, a pressure reducing device should be set at the fire hydrant.
6. Fire hydrants should adopt the same model and specifications. The diameter of the bolt mouth of the fire hydrant should be 65mm, the length of the hose should not exceed 25m, and the diameter of the water gun nozzle should not be less than 19mm. 7.
