1. The design of fire hydrant installation should consider installing in the intersection area of the street. In ensuring the eye-catching position without affecting pedestrians and vehicles, maintenance and daily drainage and drainage are convenient at the same time. Such as the sidewalk along the street. Next to the rainwater drain, beside the sidewalk tree. Some ground-type fire hydrants, due to the original installation and later changes in road elevation, buried and blocked the fire hydrant's outlet, which prevented it from draining, resulting in a change in the water quality of the fire hydrant cavity. The service life of fire hydrants. Practice shows that the number of pump couplers must be considered when designing outdoor fire hydrants. One outdoor fire hydrant corresponds to one pump coupler. Some designers consider water pump couplers, and add the number of indoor fire hydrants calculated based on the outdoor fire water consumption to the number of outdoor fire hydrants required by the pump couplers to design outdoor fire hydrants. The number of installations is too large, unrealistic and unreasonable. . In order to facilitate the use of fire trucks, fire hydrants should be evenly arranged along the fire lanes. If they can be arranged on the side of the high-rise civil building on the side of the road, it can prevent the fire truck from rolling the hose to cause the hose to burst. In order to facilitate the fire trucks to take water directly from the fire hydrant, the distance between the fire hydrant and the roadside should not be greater than 2 m; there should be a firefighter's operating site around the fire hydrant, so the distance from the outer wall of the building should not be less than 5 m. At the same time, for ease of use, regulations are stipulated The distance between the fire hydrant and the protected building should not exceed 40 m.
2. Underground fire hydrant installation design. The underground fire hydrant is designed and installed in the underground well, so the height of the fire hydrant outlet and the position of the outlet plane are the key to the convenience of water intake. Considering the water intake of the fire department, the height of the outlet from the ground should be controlled at about 30cm. It is easy to maintain and use. The position of the water outlet should be close to the side of the well. If the fire hydrant well is deep and the riser pipe connected to the fire hydrant is too long, the riser pipe should be fixed in the well to ensure safety in use.
3. For the design of outdoor fire hydrants near the super high-rise building, the distance between the fire hydrant and the pump adapter of the super high-rise building should be considered, so that once the super high-rise building catches fire, the fire department can take water and connect the pump within the shortest distance.
