Fire hydrants: Choose the right place to install

It is generally believed that as soon as the fire truck arrives at the fire, it can immediately extinguish the fire. In actual fact, a considerable number of fire engines equipped with fire brigades are waterless, such as high-power fire fighting vehicles, rescue vehicles, and fire lighting vehicles. They must be used in combination with fire-fighting fire engines. Some fire extinguishing fire trucks, due to their limited carrying capacity, urgently need to search for water sources during fire extinguishing. At this time, the fire hydrant exerted a huge water supply function.
However, in real life, due to weak fire safety awareness of some units and individuals, there is a wide variety of fire hydrants being damaged, either missing "arms" or "legs", and some fire hydrants located near the main street are occupied and buried by construction projects; Some fire hydrants were surrounded by vehicles, stalls, etc., and they could not be connected. Some of them were even interrupted by water supply, which seriously threatened the smooth development of fire fighting. Once a fire broke out, these fire hydrants would not be able to play their due role. So the correct installation of fire hydrant can play its role.
Installation points
Fire hydrants: Connected to fire water supply systems or water supply systems, with on-off valves and one or more outlets are used to supply water to fire hoses or to fire trucks. Fire hydrant is divided into indoor fire hydrant and outdoor fire hydrant.
When indoor and outdoor fire hydrants are directly supplied by municipal water supply pipes and independent fire water supply systems are used, backflow preventers shall be provided at the interface with the municipal water supply pipe network.
The dry water hydration system should not be filled for more than 3 minutes.
The number of outdoor fire hydrants should be determined based on comprehensive calculation of fire hydrants' protection radius and outdoor fire hydrant fire-fighting water consumption. The output of each outdoor fire hydrant should be calculated at 15 L/s, and the distance from the protection target should be within 5 to 40 m. , can be included in the number of outdoor fire hydrant.
Outdoor fire hydrants should be evenly arranged along high-rise buildings, and should not be centrally arranged on one side of a building. The number of outdoor fire hydrants on the side of a high-rise building's rescue surface should not be less than two.
An outdoor fire hydrant should be installed in front of the backflow preventer from the inlet pipe of the municipal water supply network.
The fire water supply pipe network application valve is divided into several independent sections, and the number of fire hydrants in each section should not exceed five.
The distance between the outdoor fire hydrant and the fire pump adapter shall not be less than 15m and not more than 40m.
Selection points
1. When the building is within the protection radius of the municipal fire hydrant within 150m and the fire-fighting water consumption does not exceed 15L/s, no outdoor fire hydrant may be provided.
2. Outdoor fire hydrants should be evenly arranged along high-rise buildings and should not be concentrated on one side of the building.
3, civil air defense project outdoor fire fighter from the civil air defense project entrance should not be less than 5m.
4. The outdoor fire hydrant of the parking lot should be set along the parking lot, and it should not be less than 7m from the nearest row of cars, and not less than 15m from the gas station or library.
5, outdoor fire hydrant should be set in a place convenient for fire engines.
6, the outdoor fire hydrant should adopt the ground type, when using the underground fire hydrant, there should be obvious signs. The underground area is used in cold areas, and the ground type is adopted in non-cold areas, and the anti-collision type is available in ground conditions.
7. Outdoor ground type fire hydrants shall have a diameter of 150mm or 100mm and two bolts with a diameter of 65mm. Outdoor underground fire hydrants shall have one each with a diameter of 100 and 65 mm.
8. The protection radius of outdoor fire hydrants should not exceed 150m, and the spacing should not exceed 120m.
9, outdoor fire hydrant from the roadside should not exceed 2m, from the house exterior wall should not be less than 5m.

Nonwoven Geotextiles

Polypropylene PP fabric non woven geotextile for geobag road landfill mine projects is used to separate,filter,reinforce, protect or drain. Geotextiles are commenly used to separate layers like clay and drainage and to protect liner from damage. Polyester Filament Needle Punched Geotextile was made from virgin polyester chips, the continous filament was extruded from
polyester chip by machine directly by spunbond process. Pet Long Fiber Nonwoven Geotextile punch together to get the stable 3D
with highter strength fabric. so Nonwoven Geotextile Fiber has high strength, good creep property excellent and erosion
resistance, aging-resistance and heat resistance.
