室内消防给水管道布置要求

来源:http://www.cx-fire.com/ 日期:2024-03-28

1.室内消火栓超过10个且室外消防用水量大于15L/s时,其消防给水管道应连成环状,且少应有2条进水管与室外管网或消防水泵连接。当其中一条进水管发生事故时,其余的进水管应仍能供应全部消防用水量。

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.高层建筑应设置独立的消防给水系统。室内消防竖管应连成环状,每根消防竖管的直径应按通过的流量经计算确定,但不应小于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.

3.60m以下的单元式住宅建筑和60m以下、每层不超过8户、建筑面积不超过650㎡的塔式住宅建筑,当设两根消防竖管有困难时,可设一根竖管,但必须采用双阀双出口型消火栓。

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.室内消火栓给水管网应与自动喷水灭火系统的管网分开设置;当合用消防泵时,供水管路应在报警阀前分开设置。

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.高层建筑,设置室内消火栓且层数超过4层的厂房(仓库),设置室内消火栓且层数超过5层的公共建筑,其室内消火栓给水系统和自动喷水灭火系统应设置消防水泵接合器。

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.

消防水泵接合器应设置在室外便于消防车使用的地点,与室外消火栓或消防水池取水口的距离宜为15~40m。水泵接合器宜采用地上式,当采用地下式水泵接合器时,应有明显标志。

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.

消防水泵接合器的数量应按室内消防用水量计算确定。每个消防水泵接合器的流量宜按10~15L/s计算。消防给水为竖向分区供水时,在消防车供水压力范围内的分区,应分别设置水泵接合器。

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.室内消防给水管道应采用阀门分成若干独立段。对于单层厂房(仓库)和公共建筑,检修停止使用的消火栓不应超过5个。对于多层民用建筑和其他厂房(仓库),室内消防给水管道上阀门的布置应保证检修管道时关闭的竖管不超过1根,但设置的竖管超过3根时,可关闭2根;对于高层民用建筑,当竖管超过4根时,可关闭不相邻的两根。

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.

阀门应保持常开,并应有明显的启闭标志或信号。

Valves should remain normally open and have clear opening and closing signs or signals.

7.消防用水与其他用水合用的室内管道,当其他用水达到小时流量时,应仍能保证供应全部消防用水。

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.允许直接吸水的市政给水管网,当生产、生活用水量达到且仍能满足室内外消防用水量时,消防泵宜直接从市政给水管网吸水。

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.严寒和寒冷地区非采暖的厂房(仓库)及其他建筑的室内消火栓系统,可采用干式系统,但在进水管上应设置快速启闭装置,管道处应设置自动排气阀。

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.
