在目前來說,
高位消防水箱的主要作用是提高臨時(shí)高壓給水系統(tǒng)的可能性,并且可以有效地臨時(shí)給水系統(tǒng)的可靠性能和系統(tǒng)化性能,提供系統(tǒng)標(biāo)準(zhǔn)工作性能的標(biāo)準(zhǔn)化程度和火災(zāi)期消防系統(tǒng)所需要的水壓;從而可以有效火災(zāi)發(fā)生后所需要的初期消防用水量。
At the early stage of the degree of standardization and fire in the current international, high fire water tank's main role is to improve the possibility of temporary high pressure water supply system, and can effectively ensure the temporary water supply system reliability and system performance, providing standard system working performance of fire protection systems require pressure; which can effectively ensure the fire occurred after the initial fire with water.
根據(jù)《建筑設(shè)計(jì)消防規(guī)范》的規(guī)定,消防水箱可以儲(chǔ)存10分鐘的儲(chǔ)水量,當(dāng)消防用水量小于低于25毫升的時(shí)候,經(jīng)計(jì)算消防水箱所需消防儲(chǔ)水量大于12m3時(shí),仍可以采用12m3的水箱。
According to the provisions of the "code of fire protection design of buildings", fire water tank can store 10 minutes of water storage, when the fire with water content less than 25 ml, through the calculation of fire water tank for fire water storage than 12m3, still can use 12m3 tank.
高位消防水箱的設(shè)置高度問題
Height of the height of the fire water tank set
根據(jù)有關(guān)部門的規(guī)定:重力自流的消防水箱應(yīng)設(shè)置在建筑的高部位,且要求能滿足不利點(diǎn)消火栓栓口靜壓的要求。高位消防水箱的設(shè)置高度應(yīng)該不利點(diǎn)消火栓靜水壓力。當(dāng)建筑高度不超過100米時(shí),高層建筑消火栓不利點(diǎn)的靜水壓力不應(yīng)低于0.07Mpa;當(dāng)建筑高度超過100米時(shí),高層建筑消火栓不利點(diǎn)的靜水壓力不應(yīng)低于0.15Mpa.因此,高位消防水箱的設(shè)置高度一定要符合靜水壓力的需求和生產(chǎn)標(biāo)準(zhǔn)。
According to the provisions of the relevant departments: gravity fire water tank should set in the highest part of a building and can meet the requirements of the worst point hydrant mouth pressure. High fire tank height should ensure that the most unfavorable point fire hydrant hydrostatic pressure. When the building height not more than 100 meters, high-rise building fire hydrant at the most unfavorable point of hydrostatic pressure should not be less than 0.07MPa; when the building height of more than 100 meters, high-rise building fire hydrant at the most unfavorable point of hydrostatic pressure should not less than 0.15Mpa. so high place fire protection water tank height must be in line with the hydrostatic pressure of demand and production standards.
消防水箱如何防凍?
Height of the height of the fire water tank set.
以下是防凍要求:
The following is an anti freezing requirement:
(1)消防用水與生產(chǎn)、生活用水合用一個(gè)水池時(shí),應(yīng)有消防用水不作他用的技術(shù)措施。
when the fire water and the production and life use a water tank, it should ensure that the fire water is not used as a technical measure for him.
(2)為了火場供水的可靠性,當(dāng)計(jì)算出的消防水池容積小于36m^3時(shí),仍應(yīng)采用36m^3;為了清池、檢修、換水時(shí)的消防應(yīng)急用水,消防水池的總?cè)莘e超過1000m^3(高層建筑消防水池的總?cè)莘e超過50Om^3)時(shí),應(yīng)分設(shè)成兩個(gè)獨(dú)立使用的消防水池。
in order to ensure the reliability of the fire water supply, when calculated the volume of fire water tank is less than 36m^3, still should be the 36m^3; in order to ensure the pool cleaning, maintenance, and water for fire emergency water and fire pool of total volume of more than 1 O00m3 (high-rise building fire water tank
The total volume of more than 50Om^3), should be divided into two independent use of the fire pool.
(3)消防水池的補(bǔ)水時(shí)間,不宜超過48h,缺水地區(qū)可延長至96h。
the fire water pool of the time, should not be more than 48h, water shortage area can be extended to 96h.
(4)消防水池的儲(chǔ)備量包括室外消防用水量時(shí),其水池應(yīng)符合有關(guān)要求。
the amount of water in the fire pool, including the amount of water used for outdoor fire protection, shall be in accordance with the relevant requirements.
(5)消防水池設(shè)計(jì)應(yīng)池內(nèi)水經(jīng)常流動(dòng),以防腐化變質(zhì)。
the design of fire water tank water should ensure that often flow, to prevent corruption.
(6)寒冷地區(qū)的消防水池應(yīng)有防凍設(shè)施口在儲(chǔ)罐區(qū)應(yīng)有易燃,可燃液體不流入消防水池的設(shè)施。
the fire pool in the cold area should be anti freezing facilities in the storage tank area should be guaranteed to be flammable, flammable liquid does not flow into the fire pool facilities.
結(jié)論與建議
Conclusion and suggestion
(1)建議三本規(guī)范對高位消防水箱儲(chǔ)水量和設(shè)置高度采用同一原則,即消防水箱應(yīng)滿足火災(zāi)初期供水不利樓層和部位消防水壓和水量的要求。
it is recommended that the three specifications of the high fire tank water storage and setting height of the same principle, that is, the fire tank should meet the fire early water supply the most unfavorable floor and parts of fire water pressure and water requirements.
(2)
高位消防水箱的儲(chǔ)水量應(yīng)該與實(shí)際的消防火災(zāi)中的供水需求總量來生產(chǎn)制作,建議消防水箱儲(chǔ)水量應(yīng)滿足60s消防系統(tǒng)所需2支水箱和4只噴頭的用水量。
high fire water tank of water storage should be with the actual fire water demand to production, suggested that the fire water storage tank water should meet the 60s fire system required 2 tank and four nozzle of water.
(3)消防水箱設(shè)置高度應(yīng)滿足火災(zāi)初期消防系統(tǒng)不利點(diǎn)所需要的低工作壓力。
the fire water tank setting height should meet the minimum working pressure of the fire protection system at the most unfavorable point.
(4)設(shè)置常高壓給水系統(tǒng)并能不利點(diǎn)消火栓和自動(dòng)噴水滅火系統(tǒng)等的水量和水壓的建筑物,如果出現(xiàn)此種情況可以不設(shè)消防水箱。
set constant high pressure water supply system and to ensure the most unfavorable point fire hydrant and sprinkler system water and water pressure building, if such a situation can not set fire water tank.
