【 Weak current College 】 all project requirements in the fire channel

1. fire-fighting channel requires

Fire engines of length, width and height are the fire truck road capacity in a decisive factor. General length of the engine are greater than or close to the height of nearly 4m 10m, width near 2.5m. Buildings》 first 6.0.2 and resistance of the section 4.3.4 provision across buildings fire truck road whose height and width £ 4m should not be less than, is in accordance with the domestic use of all fire-fighting vehicle dimensions. Taking into account the relatively rapid fire engine speed in General, through the building width should guarantee of safety, easy quick passage of vehicles, arrived at the scene, smoothly into the battle.

Fire truck road to comprehensive, pavement loads too small, the road following piping buried too shallow, ditch the use of light cover, etc., are not able to bear large fire engines. In addition, you can see from the above table, due to the large truck body length and minimum turning diameter is too large, the fire truck road carriage return field is set to 12 × 12m apparently closed, need to set the more widespread carriage return field to meet the requirements, it shall be adjusted according to the local situation is equipped with a large truck.

2, the built-up area of the setting requires fire road

Built-up area especially in the old town are often due to historical reasons, traffic conditions, fire service, inflammable building concentrated areas also hybrid small factories, warehouses, and residential canine cross. The small town of old town, as well as the bustling business district, is often regarded as the "golden section", residents look for shop, pavement occupied, temporary buildings, booth adjacent to channel narrow, in the event of fire, the fire-prone. Built-up area generally has a fire truck road, fire truck road should always be free, and no unit or individual consuming fire channel on housing, heap, look. Building on existing towns flammable concentrations to combine urban master planning, and gradually to transformation, conditional can make even slices. Fire truck road vehicles may be parked in General, to discourage other residents do not build illegal construction, stacked items.

3, factory, warehouse, yard, tank area and large public buildings fire truck road set requirements

According to the fire-fighting squadron in practice that put out the fire, as reflected in the large factories, warehouses, yard, tank farm fires, burning extremely fast, blaze, put out the fire lasted longer, if you do not have a fire ring carriageways and flat ground, causing fire vehicles not only into, inevitably, the fire engines to block close to the fire, therefore, factories, warehouses should set fire road. A, b, r factory covers an area of more than 3000 square meters or a, b, r warehouse footprint more than 1500 square meters, along the two long sides set for truck traffic and a width of not less than the flat-ground 6m. Flammable and combustible materials open yard area, liquefied gas tank farm, a, b, c liquid tank farm, should be set fire truck road or made available to the passage of fire trucks and a width of not less than the flat-ground 6m.

More than 3000-seat stadium, over 2000-seat halls and covers an area of more than 3000 square metres of galleries and other large public buildings, for building large, floor space, personnel and intensive, in order to fight the fire and when ease of evacuation, yishe ring of fire road.

4, skyscraper fire truck road set requirements

As the pace of urbanization is speeding up, increasing tension in urban areas, contributing to the construction of tall buildings. Many high-rise construction, fire safety design considerations not week and other reasons, there are many inherent dangers, the fires have occurred from time to time, with heavy losses.

To create the fire suppression, security building convenient conditions of security, you should set the ring around a high-rise building fire road. But regardless of the size of the building are called circular fire truck road do have difficulty, two buildings along the long side set the driveway. To prevent fire effect fire engine building elements onto a normal job, fire truck road road distance to wall constructed 5m. Fire truck road and between high buildings, should not prevent a fire apparatus operations set of trees, overhead pipeline, etc.

5. set the practical aspects of fire road

5 1: buildings》 and the doctrine on the street is more than the total length of 150m or buildings, to set more than 220m through building a fire road. Building does not have internal courtyard, surrounded by a ring of fire road, also needs to be set through the building's fire engine?
A: to set fire truck road, otherwise detrimental to fire suppression.
5? 2: a L-shaped construction of high-rise buildings, the total length of about 170m, along the main street of the length of the street along the 120m (district road) of length is set to cross the 50m building fire truck road?
A: buildings》 and the relevant provisions of the regulations is considered to meet the requirements for fire fighting and evacuation, the length of the two wings without restriction. The building as long as more than part of the street is located connectivity 80m streets and inner court of the pedestrian passageway, you do not have to set up a fire road.

6, fire truck road planning should be aware of other problems

Fire truck road planning, in addition to buildings》 and the relevant provisions of the regulations, you should also note the following issues:
1 fire truck road should meet the requirements of disaster relief and evacuation, their width should make sure that both sides of the trunk since the collapse of the housing disaster fire still impassable.
Within 2 blocks should be reasonable planning, construction and reconstruction of fire road. Fire channel width, spacing, and turning radius and so should be the symbol-related provisions required to ensure the smooth flow of fire fighting vehicles.
3 there are rivers, railways, through the city should take additional bridges measures to ensure the smooth flow of the engine.
4 fire trucks channel completed, no entity or individual, mining or occupied. As urban construction, you must temporarily mining or occupation is, approved unit must promptly notify fire monitoring bodies.
