1.設(shè)置常高壓給水系統(tǒng)并能保證不利點(diǎn)消火栓和自動噴水滅火系統(tǒng)等的水量和水壓的建筑物,，或設(shè)置干式消防豎管的建筑物，可不設(shè)置消防水箱,。
1. Buildings that are equipped with a high-pressure water supply system and can ensure the water volume and pressure of the most unfavorable point fire hydrants and automatic sprinkler systems, or buildings that are equipped with dry fire vertical pipes, may not need to install fire water tanks.
2.設(shè)置臨時高壓給水系統(tǒng)的建筑物應(yīng)設(shè)置消防水箱（包括氣壓水罐,、水塔、分區(qū)給水系統(tǒng)的分區(qū)水箱）,。消防水箱的設(shè)置應(yīng)符合下列規(guī)定,。
2. Buildings with temporary high-pressure water supply systems should be equipped with fire water tanks (including pressurized water tanks, water towers, and partitioned water tanks for partitioned water supply systems). The setting of fire water tanks should comply with the following regulations.
1）重力自流的消防水箱應(yīng)設(shè)置在建筑的部位。
1) The fire water tank for gravity flow should be installed at the highest part of the building.
2）消防水箱應(yīng)儲存10min的消防用水量,。當(dāng)室內(nèi)消防用水量不大于25L/s,，經(jīng)計算消防水箱所需消防儲水量大于12?時，仍可采用12?,；當(dāng)室內(nèi)消防用水量大于25L/s,，經(jīng)計算消防水箱所需消防儲水量大于18?時,，仍可采用18?。
2) The fire water tank should store fire water for 10 minutes. When the indoor fire water consumption is not more than 25L/s, after calculation, the required fire water storage capacity of the fire water tank is greater than 12? When, 12 ° C can still be used?; When the indoor fire water consumption is greater than 25L/s, the calculated fire water storage capacity required for the fire water tank is greater than 18? When, 18 ° C can still be used?.
3）消防用水與其他用水合用的水箱應(yīng)采取消防用水不作他用的技術(shù)措施,。
3) Fire water and other water tanks used for hydration should adopt technical measures that do not use fire water for other purposes.
4）消防水箱可分區(qū)設(shè)置,，并聯(lián)合給水方式的分區(qū)消防水箱容量應(yīng)與高位消防水箱相同。
4) The fire water tank can be divided into zones, and the capacity of the partitioned fire water tank with combined water supply methods should be the same as that of the high-level fire water tank.
5）除串聯(lián)消防給水系統(tǒng)外,，發(fā)生火災(zāi)后由消防水泵供給的消防用水不應(yīng)進(jìn)入消防水箱
,。
5) Except for the connected fire water supply system, the fire water supplied by the fire pump should not enter the fire water tank after a fire occurs.
3.建筑高度不超過100m的高層建筑，其不利點(diǎn)消火栓靜水壓力不應(yīng)低于0.07MPa,；建筑高度超過100m的建筑,，其不利點(diǎn)消火栓靜水壓力不應(yīng)低于0.15MPa。當(dāng)高位消防水箱不能滿足上述靜壓要求時,，應(yīng)設(shè)增壓設(shè)施,。增壓設(shè)施應(yīng)符合下列規(guī)定：
3. For high-rise buildings with a height not exceeding 100m, the most unfavorable point of the fire hydrant's static water pressure should not be less than 0.07MPa; The static water pressure of the fire hydrant at the most unfavorable point of a building with a height exceeding 100m should not be less than 0.15MPa. When the high-level fire water tank cannot meet the above static pressure requirements, pressure boosting facilities should be installed. Boosting facilities should comply with the following regulations:
1）增壓水泵的出水量，對消火栓給水系統(tǒng)不應(yīng)大于5L/s,；對自動噴水滅火系統(tǒng)不應(yīng)大于1L/s,。
1) The water output of the booster pump should not exceed 5L/s for the fire hydrant water supply system; The automatic sprinkler fire extinguishing system should not exceed 1L/s.
2）氣壓水罐的調(diào)節(jié)水容量宜為450L。
2) The regulating water capacity of the pneumatic water tank should be 450L.
4.建筑的室內(nèi)消火栓,、閥門等設(shè)置地點(diǎn)應(yīng)設(shè)置性固定標(biāo)識,。
4. Permanent fixed signs should be set up at the locations where indoor fire hydrants, valves, etc. are installed in buildings.
5.建筑內(nèi)設(shè)置的消防軟管卷盤的間距應(yīng)保證有一股水流能到達(dá)室內(nèi)地面任何部位，消防軟管卷盤的安裝高度應(yīng)便于取用,。
5. The spacing between fire hose reels installed inside the building should ensure that a stream of water can reach any part of the indoor floor, and the installation height of fire hose reels should be easy to access.
