Firefighting water supply system for high building

Abstract

The invention provides a firefighting water supply system for a high building, the firefighting water supply system comprises a top layer water tank, a plurality of middle water tanks and a bottom layer water tank which are arranged in the height direction of the building in order from top to bottom, the top layer water tank and the plurality of middle water tanks are connected in order from top to bottom through water supplementing pipelines, a fire fighting water supply pipeline system is connected to the top layer water tank and each middle water tank respectively, a water supply dry pipe is arranged between the bottom layer water tank and the top layer water tank, and a high-pressure pump is arranged between the water supply dry pipe and the bottom layer water tank. According to the firefighting water supply system for the high building, a pump set can be centralized on the base layer of an ultra-high building, a lot of high space of the ultra-high building is saved, and vibrationand noise pollution cannot be caused to the middle floors; at the same time, 'one pump to top' type water supplying is adopted, only one water supply dry pipe is required to be equipped for the system, relay is not needed, and the water supply system is simple and efficient.

Description

technical field [0001] The invention relates to the technical field of water supply for high-rise buildings, in particular to a fire-fighting water supply system for high-rise buildings. Background technique [0002] At present, the water supply system of super high-rise buildings usually adopts the partition water supply method of gravity or pressure, and the fire water supply method inside the super high-rise building mainly includes the partition connection fire water supply method, the parallel partition fire water supply method, and the partition decompression fire water supply method: [0003] 1. Connect the fire water supply system [0004] Such as figure 1 As shown, the connected fire water supply system includes a plurality of fire-fighting pools 20 arranged sequentially from bottom to top according to the height of the floors. The multiple fire-fighting pools 20 are in a sequential connection relationship, and there are transmission pumps 221 between adjacent fire...

AI Technical Summary

Problems solved by technology

[0005] The main disadvantages of the above-mentioned connection to the fire water supply system include: 1) a pump room needs to be installed on the middle floor, and the layout of the pump group and pipelines needs to occupy a lot of valuable high-rise space; 3) The failure of any pump group in any partition will cause the upper partition to fail to supply water normally, and the reliability of the water supply system is low; 4) The equipment layout is scattered, which is not conducive to maintenance and management

[0008] The main disadvantages of the aforementioned parallel partition fire water supply system include: the parallel water supply system will increase the number of water supply risers in the building, consume pipe materials, and increase costs

The disadvantage of this partitioned decompression fire protection water supply system is that it has high requirements for water pump head and water supply pipeline pressure resistance, and this method is only suitable for high-rise buildings no higher than 200 meters
