When there are more than 10 indoor fire hydrants and the outdoor fire water consumption is greater than 15L/s, the fire water supply pipeline should be connected in a circular shape, and at least 2 inlet pipes should be connected to the outdoor pipeline network or fire water pump. When one of the inlet pipes experiences an accident, the remaining inlet pipes should still be able to supply all firefighting water.
2.高層建筑應(yīng)設(shè)置獨(dú)立的消防給水系統(tǒng)。室內(nèi)消防豎管應(yīng)連成環(huán)狀,，每根消防豎管的直徑應(yīng)按通過的流量經(jīng)計(jì)算確定,，但不應(yīng)小于DN100。
2. High rise buildings should be equipped with independent fire water supply systems. Indoor fire protection vertical pipes should be connected in a circular shape, and the diameter of each fire protection vertical pipe should be determined by calculation based on the flow rate passed through, but should not be less than DN100.

For unit residential buildings below 3.60m and tower residential buildings below 60m, with no more than 8 households per floor and a building area of no more than 650 square meters, when it is difficult to install two fire vertical pipes, one vertical pipe can be installed, but double valve and double outlet fire hydrants must be used.
4.室內(nèi)消火栓給水管網(wǎng)應(yīng)與自動(dòng)噴水滅火系統(tǒng)的管網(wǎng)分開設(shè)置,；當(dāng)合用消防泵時(shí),，供水管路應(yīng)在報(bào)警閥前分開設(shè)置。
4. The indoor fire hydrant water supply pipe network should be separated from the pipeline network of the automatic sprinkler fire extinguishing system; When using a shared fire pump, the water supply pipeline should be separated before the alarm valve.
5.高層建筑,，設(shè)置室內(nèi)消火栓且層數(shù)超過4層的廠房（倉庫）,，設(shè)置室內(nèi)消火栓且層數(shù)超過5層的公共建筑，其室內(nèi)消火栓給水系統(tǒng)和自動(dòng)噴水滅火系統(tǒng)應(yīng)設(shè)置消防水泵接合器,。
5. For high-rise buildings, factories (warehouses) with indoor fire hydrants and more than 4 floors, and public buildings with indoor fire hydrants and more than 5 floors, their indoor fire hydrant water supply system and automatic sprinkler fire extinguishing system should be equipped with fire pump adapters.
消防水泵接合器應(yīng)設(shè)置在室外便于消防車使用的地點(diǎn),，與室外消火栓或消防水池取水口的距離宜為15~40m。水泵接合器宜采用地上式,，當(dāng)采用地下式水泵接合器時(shí),，應(yīng)有明顯標(biāo)志。
The fire pump adapter should be located outdoors in a location convenient for fire trucks to use, and the distance from the outdoor fire hydrant or fire water tank inlet should be 15-40m. The water pump adapter should be above ground, and when using an underground water pump adapter, there should be clear markings.
消防水泵接合器的數(shù)量應(yīng)按室內(nèi)消防用水量計(jì)算確定,。每個(gè)消防水泵接合器的流量宜按10~15L/s計(jì)算,。消防給水為豎向分區(qū)供水時(shí)，在消防車供水壓力范圍內(nèi)的分區(qū),，應(yīng)分別設(shè)置水泵接合器,。
The number of fire pump couplings should be determined based on the indoor fire water consumption calculation. The flow rate of each fire pump adapter should be calculated at 10-15L/s. When the fire water supply is in vertical zones, water pump couplings should be installed in the zones within the pressure range of the fire truck's water supply.
6.室內(nèi)消防給水管道應(yīng)采用閥門分成若干獨(dú)立段。對(duì)于單層廠房（倉庫）和公共建筑，檢修停止使用的消火栓不應(yīng)超過5個(gè),。對(duì)于多層民用建筑和其他廠房（倉庫）,，室內(nèi)消防給水管道上閥門的布置應(yīng)保證檢修管道時(shí)關(guān)閉的豎管不超過1根，但設(shè)置的豎管超過3根時(shí),，可關(guān)閉2根,；對(duì)于高層民用建筑，當(dāng)豎管超過4根時(shí),，可關(guān)閉不相鄰的兩根,。
6. Indoor fire water supply pipelines should be divided into several independent sections using valves. For single story factory buildings (warehouses) and public buildings, the number of fire hydrants that need to be stopped for maintenance should not exceed 5. For multi story civil buildings and other factories (warehouses), the arrangement of valves on indoor fire water supply pipelines should ensure that no more than one vertical pipe is closed during maintenance, but when more than three vertical pipes are set, two can be closed; For high-rise civil buildings, when there are more than 4 vertical pipes, the two non adjacent pipes can be closed.
閥門應(yīng)保持常開，并應(yīng)有明顯的啟閉標(biāo)志或信號(hào),。
Valves should remain normally open and have clear opening and closing signs or signals.
7.消防用水與其他用水合用的室內(nèi)管道,，當(dāng)其他用水達(dá)到小時(shí)流量時(shí)，應(yīng)仍能保證供應(yīng)全部消防用水,。
7. Indoor pipelines for fire water and other hydration purposes should still be able to supply all fire water when the maximum hourly flow rate of other water is reached.
8.允許直接吸水的市政給水管網(wǎng),，當(dāng)生產(chǎn)、生活用水量達(dá)到且仍能滿足室內(nèi)外消防用水量時(shí),，消防泵宜直接從市政給水管網(wǎng)吸水,。
8. For municipal water supply networks that allow direct water absorption, when the production and domestic water consumption reaches its maximum and can still meet the indoor and outdoor fire water consumption, the fire pump should directly absorb water from the municipal water supply network.
9.嚴(yán)寒和寒冷地區(qū)非采暖的廠房（倉庫）及其他建筑的室內(nèi)消火栓系統(tǒng)，可采用干式系統(tǒng),，但在進(jìn)水管上應(yīng)設(shè)置快速啟閉裝置,，管道處應(yīng)設(shè)置自動(dòng)排氣閥。
9. Indoor fire hydrant systems for non heating factories (warehouses) and other buildings in extremely cold and cold areas can use dry systems, but quick opening and closing devices should be installed on the inlet pipes, and automatic exhaust valves should be installed at the highest point of the pipes.
