The height of the bolt from the ground is.

An above-ground fire hydrant is an outdoor above-ground fire water supply facility. It is used to supply water to fire trucks or directly connect with hoses and water guns to extinguish fires, and is a special facility for outdoor fire water supply. The upper part of it is exposed to the ground, and the logo is obvious, making it easy to use.

It is composed of valve body, elbow, valve seat, valve disc, drain valve, valve stem and interface and other parts.

Above-ground fire hydrants are an essential fire-fighting equipment in cities, especially in urban areas and areas with fewer rivers to ensure fire water supply. Factories and mines, warehouses, docks, freight yards, high-rise buildings, public places and other densely populated areas should be installed if conditions permit.

It is widely believed that as soon as a fire truck arrives at the fire scene, it can immediately come out with water to extinguish the fire. In fact, a considerable part of the fire trucks equipped in the fire brigade do not carry water, such as lifting fire trucks, emergency rescue vehicles, fire lighting vehicles, etc., which must be used in conjunction with fire extinguishing fire trucks.

Some firefighting fire trucks also urgently need to find water sources when extinguishing fires due to their limited water capacity. At this time, the fire hydrant plays a huge role in the supply of water.

However, in real life, due to the weak awareness of fire safety of some units and individuals, fire hydrants have been damaged in a variety of ways, either missing "arms" or missing "legs", and some fire hydrants located next to the main streets have been occupied and buried by construction projects; Some fire hydrants are so enclosed by vehicles and stalls that they cannot be connected at all, and some even have their water supply cut off.

Outdoor fire hydrants.

According to point 3 in the building regulations, the distance between fire hydrants shall not be greater than 120m; Point 4: The protection radius of the fire hydrant shall not be greater than 150m;

Indoor fire hydrants: According to point 5 of the building regulations, the spacing of indoor fire hydrants should be determined by calculation. The spacing of indoor fire hydrants in high-rise workshops (warehouses), high-bay warehouses and Class A and B workshops should not be greater than 30m; In other single-storey and multi-storey buildings, the spacing of indoor fire hydrants should not be demolished at 50m

In high gauge: The spacing of fire hydrants should be determined by calculations, and high-rise buildings.

It should not be larger than 30m, and the podium should not be larger than 50m

In addition, there are many other regulations, which are detailed in the construction regulations and high regulations.

Summary. Hello dear, your question is as follows: Generally speaking, the distance from the ground is about to be controlled in meters, and the specific size of the fire box should be determined, so that the calculation of the height will be more accurate.

For example, when the center of the fire hydrant hole is 15 cm, if it is calculated according to this, the installation height of the fire box can be controlled at about 80 cm. I hope mine can help you, and I wish you a happy life and a healthy, happy and uplifting day every day

How many meters should the height of the fire hydrant be from the ground?

Hello, I have seen your question, I am sorting out the answer, it takes time to type, please be patient for a while

Hello dear, your question is as follows: Generally speaking, the distance from the ground is about to be controlled in meters, and the specific size of the fire box should be determined, so that the height will be more accurate to calculate the slag socks. For example, when the loss of the central limb beam of the fire hydrant hole is 15 cm, if it is calculated according to this, the installation height of the fire box can be controlled at about 80 cm.

I hope that I can help you, and I wish you a happy life and a healthy, happy and uplifting day

How many meters should the height of an outdoor fire hydrant be from the ground?

Hello dear, your question is as follows: outdoor fire hydrants are generally installed on the ground, and the height of the fire hydrants on the ground is usually at the height of the ground rock Bo meters. If the silver wax is installed on the wall, the height is at the height of meters from the ground.

The installation distance of the fire hydrant needs to be determined according to the local fire code and standards. Normally, the installation distance of the fire hydrant should meet the following requirements:

The fire hydrant should not be more than 30 meters away from the external wall of the building, and generally not less than 20 meters.

The distance between fire hydrants should be determined according to the actual local situation and fire regulations, but in general, the distance between two adjacent fire hydrants should not exceed 90 meters.

Fire hydrants should be set up on the ground and kept as far away as possible from obstacles, such as cars, telephone poles, etc.

Fire hydrants should be clearly marked so that firefighters can find them quickly.

Therefore, the specific installation distance of how many meters is required for a fire hydrant needs to be determined in combination with the specific local conditions and specifications, and the above principles need to be observed in general.
