How do you mean to install? Or is it the location of the setting or something?
If it is an installation, refer to the installation drawing of the outdoor fire hydrant.
If it is a location, it should be done according to the requirements of the "Code for Fire Protection Design of Buildings".
-
According to what you said, it is necessary to set up an outdoor fire hydrant.
It is also necessary to set up indoor fire hydrants and configure fire extinguishers as required.
The following two conditions need to be met for outdoor fire hydrants not to be installed.
1. Class E plant with fire resistance grade not lower than Grade II and construction area not more than 3000;
2. Residential areas with no more than 500 people and no more than two floors of buildings may not be equipped with an outdoor fire hydrant system.
-
Thanks, well, it looks like it needs to be set up.
-
The low regulations say: the number of people in the residential area does not exceed 500 and the number of floors of the building does not exceed two floors of the residential area, can not be set up fire water supply, I don't know whether this provision applies to this kind of kindergarten project.

Outdoor fire hydrants are mainly used by fire trucks to draw water from the municipal water supply pipe network or outdoor fire water supply pipe network to extinguish fires, and can also be directly connected to water hoses and water guns to extinguish fires.
Fire protection requirements for outdoor fire hydrant arrangement:
1. Setting requirements, the installation of outdoor fire hydrants should be obviously easy to find, convenient for water operation, and underground fire hydrants should also be equipped with obvious fixed signs near the ground. Above-ground fire hydrants are selected for installation on warm ground and cold ground in basements.
2. Road paving, outdoor fire extinguishing in municipal or residential areas. Outdoor fire hydrants should be laid along the road, and when the width of the road exceeds 60m, it should be set on both sides and close to the intersection.
3. The quantity, the number of outdoor fire hydrants should be determined according to its protection radius, the flow rate of Qinglu and the amount of outdoor fire protection, and the flow rate of each fire hydrant should be 10-15L s. For high-rise buildings, municipal fire hydrants within 40m can be included in the number of outdoor fire hydrants in the building; For multi-storey buildings, the municipal fire hydrant protection radius is within 150m, if the fire water consumption is not more than 15L s, the building can not be equipped with an outdoor fire hydrant.
Legal basis] Fire Protection Law of the People's Republic of China
Article 28 No unit or individual shall damage, embezzle, or dismantle or stop using fire-fighting facilities and equipment without authorization, and shall not bury, occupy, or block fire hydrants or occupy fire spacing, and shall not occupy, block, or close evacuation channels, safety exits, and fire truck passages. Doors and windows in crowded places shall not be equipped with obstacles that affect escape and fire fighting and rescue. Article 29 The unit responsible for the maintenance and management of public fire-fighting facilities shall keep the public fire-fighting facilities such as fire water supply, fire communication, and fire truck passage intact and effective.
If the fire brigade may be affected in the construction of roads, power outages, water outages, and communication lines, the relevant units must notify the local fire and rescue agencies in advance. Article 47 Fire trucks and fire boats shall give way to other vehicles, ships and pedestrians when they go to perform fire fighting or emergency rescue tasks on the premise of ensuring safety, and shall not be restricted by driving speed, driving route, driving direction and command signals; Toll roads and bridges are exempt from vehicle tolls.

Dear, I'm glad to answer your <>
Answer: The difference between indoor fire hydrants and outdoor fire hydrants is as follows: 1. The types of indoor fire hydrants are divided into indoor ordinary fire hydrants, vacuum fire hydrants, rotary fire hydrants, and rotary pressure reduction fire hydrants.
Outdoor fire hydrants are divided into underground fire hydrants, above-ground fire hydrants, above-ground anti-collision fire hydrants, and above-ground anti-collision pressure regulating fire hydrants. 2. The appearance difference is that the indoor fire hydrant is generally a 65 caliber water outlet, and the number is one or two. Outdoor fire hydrants generally have three water outlets.
Two of 65 calibers, one of 100, or two of 80 of 150. 3. The location difference indoor fire hydrant is installed in the fire hydrant box, and is generally used in combination with the fire hose, self-rescue reel, water gun and interface. Outdoor fire hydrants are installed in outdoor places and can be directly connected to fire hoses or fire trucks.
4. The difference between water pressure and indoor fire hydrant should be high-pressure or temporary high-pressure water supply system, and the water pressure standard of different floors is different on different occasions, but generally it should not be lower than or exceed, otherwise pressure reduction measures should be taken. Outdoor fire hydrants can be used high pressure, temporary high pressure and low pressure water supply system, the usual operating pressure should not be less than the difference in use, indoor fire hydrant is the indoor pipe network to supply water to the fire site, with valve interface, for factories, warehouses, high-rise buildings, public buildings and ships and other indoor fixed fire protection facilities. Outdoor fire hydrant is a water supply facility set up on the fire water supply pipe network outside the building, which is mainly used by fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network to extinguish fires.
6. The fire extinguishing method is different from the indoor fire hydrant, which is manually connected to the bolt mouth to extinguish the fire, and there is also a fire hydrant button in the fire hydrant box, which can be used to remotely start the fire pump to replenish the fire hydrant. Outdoor fire water supply pipelines can use high-pressure, temporary high-pressure and low-pressure pipelines, and outdoor fire water supply in towns, residential areas, enterprises and institutions generally use low-pressure water supply systems, which are often combined with domestic and production water supply pipelines.
