The invention discloses an ultrahigh-rise building fire
water supply method and a
system thereof. The method comprises the following steps: S1, determining the height and floors of an ultrahigh-rise building, and selecting water transferring positions in the ultrahigh-rise building; S2, arranging
water storage tanks at the water transferring positions, building a
water supply station on the ground, and arranging
water supply pumps in the water supply
station; S3, connecting the water supply pumps with the
water storage tanks through pipelines, connecting the
water storage tanks of the adjacentwater transferring positions through pipelines, and arranging
electric control valves on the pipelines; S4, arranging a
water level monitoring component in each
water storage tank, and electrically connecting the
water level monitoring components, the
electric control valves and the water supply pumps with a
control system; S5, connecting the water storage tanks with fire water supply positions of corresponding floors; and S6, detecting water levels of the water storage tanks through the
water level monitoring components, and controlling the water supply pumps and the
electric control valvesaccording to the water levels so as to ensure sufficient water in the water storage tanks through the
control system. The method can ensure the high-rise fire water and avoid the occurrence of insufficient water supply in case of a
fire hazard.
