　　Outdoor fire hydrant

　　Outdoor fire hydrants are water supply facilities installed on the fire water supply network outside buildings, mainly used for fire trucks to draw water from the municipal water supply network or outdoor fire water supply network to extinguish fires. They can also be directly connected to water hoses or water guns to discharge water for extinguishing fires.

　　Therefore, outdoor fire hydrant systems are also one of the important fire-fighting facilities for extinguishing fires.

　　placement location

　　1. Fire hydrants should be placed in public shared spaces such as corridors or halls, usually within the walls of these spaces, and should not be decorated in any way. They should be clearly marked (indicating "fire hydrant") and no obstacles should be placed in front of them to avoid affecting the opening of the fire hydrant door.

　　2. Fire hydrants are generally not installed in rooms (such as private rooms), which does not comply with fire safety regulations and is not conducive to timely rescue by firefighters.

　　Installation Design of Outdoor Fire Hydrants

　　1. The installation design of ground type fire hydrants should consider installing them in the intersection area of the street, in a conspicuous and non obstructive position for pedestrians and vehicles, while also considering maintenance and convenient daily drainage and drainage. Such as along the sidewalk, next to rainwater drainage outlets, and on the side of pedestrian trees. Some ground type fire hydrants, due to their initial installation and subsequent changes in road elevation, bury or block the water outlet of the hydrant with soil, resulting in changes in the water quality inside the hydrant chamber and rusting of the screw rod, affecting the water quality of the pipe network and the service life of the hydrant. 2. Installation design of underground fire hydrants. The design and installation of underground fire hydrants are located in underground well rooms, so the height and plane position of the fire hydrant outlet are key to the convenience of water intake. Considering the water intake connection from the fire department, the height of the outlet from the ground should be controlled at around 30cm, and the plane position of the outlet should be adjacent to the wellhead for maintenance and use convenience. If the fire hydrant well is very deep and the connecting riser of the fire hydrant is too long, the riser should be fixed inside the well to ensure safety during use. 3. For the design of outdoor fire hydrants near super high-rise buildings, the distance between the hydrant and the water pump adapter of the super high-rise building should be considered, so that in case of a fire in the super high-rise building, the fire department can take water and add pump connections within a short distance.

　　4. Due to the influence of planning and other factors, it is common to combine the functions of control valve wells and fire wells into one, commonly known as nested wells. This seems to save planning space and achieve dual functions of one well, but it also brings management drawbacks. Once the fire hydrant needs maintenance, the valve needs to be closed, which will affect the normal downstream water supply. Similarly, when repairing downstream pipelines, closing the valve will affect the normal use of the fire hydrant, and the normal usage rate of the fire hydrant at that location will inevitably decrease. This is extremely unfavorable for the management of the use of fire hydrants for temporary military use. Secondly, because the well has dual functions, and whether the manhole cover is mainly a fire manhole cover or a valve manhole cover brings confusion in management and use, the design should avoid this type of manhole cover as much as possible.
