消防车道设计规范（Code for design of fire lane）消防车道设计规范(Code for design of fire lane)Tall (refers to the ten and ten layers above the house.) Buildingfire lane design requirements: low layer, multi-layer, high-rise residential residential area should be equipped with fire lanes, the turning radius should not be less than 6m. The surrounding high-rise residential should has a circular driveway, the turning radius shouldnot be less than 12m (in some places is 9 meters). Around 1 of high-rise buildings, should set up a fire ring road. When there are difficulties with ring lane, two long side along the high-rise building set fire road. When the high-rise buildings along the length of more than 150m or the total length of more than 220m, should be through the fire lane of high-rise building is arranged in a proper position. High-rise buildings should be equipped with pedestrian streets and communicated with the inner courtyard, a distance not more than 80m between channels. 2 high-rise building courtyard or patio, while the short side length of more than 24m, should be equipped with fire lane into the inner court or patio. 3 for the fire water natural water and fire water, should set the fire lane. 4 fire lane width should not be less than 4.00m. The firelane from the high-rise building external wall is larger than 5.00m, the fire lane over below 4.00m range should not be obstacles. At the end of the 5 type fire lane should be equipped with back lanes or enter the field, enter the field of not less than 15m * 15m. Large fire trucksenter the field should not be less than 18m * 18m. The fire lanepipeline and Angou, should be able to withstand the pressure of fire fighting vehicles. 6 through the fire lane of the high-rise building,its width and height clearance shall not be less than 4.00m. Between the 7 fire lane and high-rise buildings, should not hinder the operation of setting firetruck climbing trees, overhead lines etc.. 8 general fire truck length is greater than or equal to the height of 10m, near 4m, width of nearly 2.5m. Climbing surface fire fire climbing surface called fire climbing high-rise building surface, fire platform, a fire truck near the top of the main building, carry out fire truck climbing, and firefighters into the high-rise building, fire fighting, rescue trapped in the building facade. According to the national code for fire protection design of buildings, high-rise buildings must be set fire climbing surface, and not for other purposes. Set the fire climbing surface is required in order to ensure the operation of the fire take a car, the high-rise residential households timely rescue, therefore, fire climbing surface should be close to the residential function of the stairs, when there are difficulties, climbing surface should be close to each residential balcony or window. High-rise residential should set the climbing surface fire, and should meet the following criteria: 1 residential tower fire climbing facial should not be less than residential surrounding 1/4 length; a long edge length of climbing surface fire 2 unit, corridor style residential should not be less than3 of the housing; the fire climbing surface should be close toresidential or public stairs the balcony and window; 4 side fireclimbing surface of the podium, the building height should be no more than 5m, and the depth should not exceed 5 4m; the fire climbing surface should not be designed with tall trees shall not hinder climbing between 6 glass curtain wall climbing surface and building a large area. 7 inthe range of climbing surface should be a safe exit building. 8, high-rise residential should be on one side of the climbing surface, combined with the fire lane is not less than a fire climbing venues, each stand high fire area should not be less than 15mx8m.9, fire uprise venues shall comply with the following provisions:from fire uprise venues exterior walls of the house should not be less than 5m, the outer points to fire climb the edges of the horizontal distance should not be greater than 10m; no fire stand high ramp, the ramp slope should be less than 15%; the use of municipal roads as fire climbing venues, the green the tram network, overhead lines, dyeing and other facilities shall not affect the fire truck stop, operation. Thefire lane 10, high-rise residential, should avoid the fire stand high underground pipelines, ditch, pond, septic tank fireThe car load of underground facilities, layout, fire climbing venues fire lane in underground buildings when calculating the weight of thecar should consider the fire take a load of floor of underground buildings. For the ecological fire channel base design requirements: (1). The foundation soil shall be compacted layer by layer,Density should reach more than 85%: belong to the similar silt layer, should be filled blocks or even replacement of sand and compacted to dense density should meet the general requirements of concrete fire lane based bearing (Note: refer to the local fire vehicle traffic design standards). (2) 150mm thick sand layer. The specific practice is: 20%,20 35mm sand gravel diameter 70%, 10% soil mix, flat rolled to dense (or even local sand can be). The fire lane gravel layer and stable layer powder practices should be referred to the local fire lane design standard. (3). Set the 80mm thick stable layer (as working layer) approach is: Clay gravel, coarse sand, 10% 30% 60% and add organic fertilizer amount, stir evenly, spreading in the bearing layer is compacted on the compacted, can be used as thebase board grass. (4). If the base and a little organic fertilizer, artificial grass paving board, according to the size of the fire channel selection to products. (5). Complete the grass planting board after pavement should be in the groove in grass grid filling is slightlyhigher than that of grass planting soil 6mm. (6). In the upper soil planting turf grass planting board or sprinkled turf grass seed, to beon the surface layer of soil compaction of turf grass, waterconservation for grass survival after the vehicle can pass.==================================== fire channelrequirements of fire engines in length and width and height is a decisive factor affecting the fire lane capacity. General fire truck length is greater than or equal to the height of 10m, near 4m, width ofnearly 2.5m. "Building regulations" article 4.3.4 and article 6.0.2 of the "high regulation" provisions of the fire lane through building the height and width of not less than 4m, is in accordance with the various dimensions of fire vehicles for domestic use and determined. Considering the car speed is generally faster, through building width should ensure the safety factor, to facilitate the rapid transit vehicles, arrived at the scene, successfully put into battle. The fire lane should be comprehensive, the road load is too small, the road below pipe buried shallow ditches with light cover etc., can bear large fire truck traffic. In addition, as can be seen from the table, due to the large fire truck body length and minimum turning diameter is too large, therefore, enter the field set the fire lane for 12 * 12m was impassable, enter the field to set a larger area to meet the use requirements, it shall be determined according to the local actual equipped with large fire engines. 2, built-up area fire lane setting requirements of the built-up area especially in old urban areas often dueto historical reasons, poor traffic conditions, fire water supply shortage in the inflammable built-up areas is also mixed with small factories, warehouses, and residential cross. The old city area of small towns, but also often is a bustling business district, is regarded as "lots of gold", the residents shop sale, road occupied, temporary buildings, booth adjacent to a narrow channel, once the fire, easy to form huoshaolianying. The built-up area in general has the fire lane,the fire lane should be kept open, any units and individuals areforbidden to occupy the fire channel, take the house heap, shetan. The existing urban built-up areas with combustible overall urban planning, gradually change, conditions can be modified. The fire lane is generally not parked other vehicles, to dissuade residents not to build illegal buildings, piled up in goods. 3, factory, warehouse, yard, storage area and large public building fire lane set requirementsAccording to the fire squadron in the fire fighting practice reflect the larger area of the factory, warehouse, yard, tank fire, burning fast, fierce fire, fire fighting over a long period of time, if there is nofire ring lane and Esplanade, is bound to cause fire vehicles not only into, is bound to cause blockage, so that fire engines to near the fire, therefore, factories and warehouses should set the fire lane. A a, B and C plant covers an area of over 3000 square meters or a B C warehouse covers an area of over 1500 square meters,For the passage of fire engines and a width of not less than 6m ofthe Esplanade set along the two long side. Flammable and combustible materials open yard area, liquefied gas tank, a, B and C liquid storage tank zone should be set fire lanes orfor the passage of a fire truck and a width of not less than 6m ofthe esplanade. More than 3000 seat stadium, more than 2000 seats in the synagogues and covers an area of over 3000 square meters of exhibition hall and other large public buildings, because the construction of large volume, large area, and personnel intensive, in order to facilitate the occurrence of fire fighting and evacuation, are advised to set up a ringof fire lane. 4, high-rise building fire lane set requirements with the city the pace continues to accelerate, city land increasingly tense, promote the construction of high-rise building. Many high-rise buildings, the fire protection design of inconsiderate and other reasons, there are many inherent risks, fires have occurred, suffered heavy losses. Forfire fighting and rescue work to create convenient conditions, guarantee the safety of the building, should be set around the fire lane in high-rise buildings around. But regardless of the building size, will be required to ring the fire lane have difficulty, two long side buildings along the lane is set. In order to prevent the fire building collapse influence the normal operation of fire lane, Lane from the fire wall should be 5m. Between the fire lane and high-rise buildings, should not hinder the operation of setting fire truck climbing trees, overheadlines etc.. 5 practical problems, set the fire Lane 5? 1 to ask: "building regulations" and "high regulation" provisions along the length of more than the total length of 150m or the building of more than 220m, to be set up through the building of the fire lane. No building courtyard, surrounded by a ring of fire lane, the fire lane also need to set up through the building? Answer: to set the fire lane, or not conducive to fire fighting. 5? 2: a L type of high-rise buildings, building a total length of about 170m, along thestreet length of 120m, along the street (Road area) the length is50m, to set up the fire lane through the building? Answer: "building regulations" and "high regulation" the relevant provisions areconsidered to meet the requirements of fire fighting and evacuation under the premise of not to limit the length of the wings. The buildings along the street as long as more than 80m part of connected streets and walkways to the inner court, without setting up the fire lane. Other issues should pay attention to fire fire Lane 6, Lane planning planning, in addition to the relevant provisions in the "building regulations" and "high regulation", should also pay attention to the following problems: 1 fire lane should meet the disaster relief and evacuation requirements, its width should ensure that the roads on both sides of houses affected after the collapse of the fire truck can still pass through. 2 districts shall reasonably plan the construction and renovation of the fire lane. Fire channel width, spacing and turning radius are the symbols of the requirements, ensure the fire vehicle smoothly. There are 3 city through rivers, railways, bridges and other measures should be taken to add, ensure unblocked fire truck.4 fire channel is completed, any units or individuals, are not allowed to occupy or dig. Due to urban construction, must be temporary mining or occupation is approved, units must promptly notify the public security fire supervision mechanism. First, for the ecological fire channel base design requirements: (1). The soil should be tamped density should reach more than 85%: belong to the similar silt layer, should be filled blocks or even replacement of sand and compacted to dense density should meet the general requirements of concrete fire lane basedbearing (Note: according to the local fire vehicle traffic design standards). (2) 150mm thick sand layer. The specific practice is: 20%,20 35mm sand gravel diameter 70%, 10% soil mix, flat rolled to dense (or even local sand can be). The fire lane gravel layer and stable layer powder practices should be referred to the local fire lane design standard. (3). Set the 80mm thick stable layer (as working layer) approach is: Clay gravel, coarse sand, 10% 30% 60% and add organic fertilizer amount, stir evenly, spreading in the bearing layer is compacted,Compacted, can be used as the base board grass. (4). If the base and a little organic fertilizer, artificial grass paving board, according to the size of the fire channel selection to products. (5). Complete the grass planting board after pavement should be in the groove in grassgrid filling is slightly higher than that of grass planting soil 6mm. (6). In the upper soil planting turf grass planting board or sprinkled turf grass seed, to be on the surface layer of soil compaction of turf grass, water conservation for grass survival after the vehicle can pass.。
