At the beginning of the year, Xiao Bian saw a piece of news that introduced: "Fire engines cannot come in! If a fire burns a newly renovated new house, who is going to lose?" One due to the width and the road of the fire truck The wide problem has affected the containment of fire and caused huge economic losses!
So today Xiao Bian came to talk with everyone about the width of the fire engine?
Fire truck
1. How long is the length, width and height of a fire truck a safe value?
The length, width and height of a fire truck are a decisive factor influencing the capacity of a fire lane. The average length of a fire truck is greater than or close to 10m, the height is nearly 4m, and the width is nearly 2.5m. Article 6.0.2 of the Regulation and Article 4.3.4 of the High Regulations stipulate that the net height and the net width of a fire lane passing through a building shall not be less than 4m, that is, the dimensions of various firefighting vehicles used in China. And ok. Considering that the speed of fire engines is generally faster, a certain safety factor should be ensured in the width of buildings when passing through buildings, facilitating the rapid passage of vehicles, reaching the fire field, and successfully entering the battle.
The fire-fighting lanes should be well-planned, the road surface loads should be too small, the pipelines under the roads should be buried too shallow, and the ditches should be light-covered, and they should not be able to withstand the passage of large-scale fire engines. In addition, as can be seen from the above table, because the length of the body and the minimum turning diameter of the large-scale fire engine are too large, the return carriageway of the fire lane is set to be 12×12m and obviously cannot pass through, and a larger area of ​​return is required. In order to meet the requirements for use, this should be determined according to the actual large-scale fire trucks in the area.
2. Requirements for setting up fire lanes in built-up areas
The built-up areas, especially the old urban areas, are often due to historical reasons, poor traffic conditions, insufficient water for firefighting, and mixed small factories and warehouses in flammable buildings. The old town in a small town is also often a bustling business district. It is considered a “golden locationâ€. Residents open stores and set up booths. The roads are occupied. Temporary buildings and stalls are connected and the passage is narrow. Once a fire occurs, it is easy to form a fire. . Fire-fighting lanes are generally set up in built-up areas. Fire lanes should always be kept unblocked, and no unit or individual is allowed to occupy fire-fighting lanes to build houses, piles, or booths. The intensively combustible buildings in existing towns must be combined with the overall urban planning, and be gradually transformed, and conditions can be contiguous to transform. The fire lanes are generally not allowed to park other vehicles. It is necessary to discourage residents from constructing illegal buildings and stacking items.
