What is the standard slope of the fire lane?
4.3.1 longitudinal slope of road1 control indexes for longitudinal slope of residential area are shown in table 4.3. 1.2, the base motor vehicle lane is connected with the urban road. When the slope is large, a buffer section should be set up, and the urban road space should not be occupied.3 in the difficult areas with large topographic gradients, the longitudinal slope of the road should be no more than 11%, the slope length should not exceed lOOm, and the road surface should be anti skidding measures.
4 when the terrain elevation large base road longitudinal slope and slope length is more than 10%, more than 30m, should be set on foot ladder on one side of the road, every step of not less than 3, each stairway rose 1.2 ~ 1.5m should set the rest platform width not less than 1.5m; ladderway continuously increases more than 5m, should be set the rest of the platform. Should also set the turning platform, its width is not less than the width of the ramp stairway, and attached to a bicycle ramp beside.5, the pedestrian road at all levels of the residential area should consider barrier free design, the sidewalk longitudinal slope should not be greater than 2.5%, in the pedestrian walkway, steps should be equipped with wheelchair ramps and handrails.There is a table in the above regulations, can not paste
Other specifications provide for the road. The fire lane is the same as other lanes. There is no special regulation for the lane slope in the fire codeSuggest that you design according to < < national civil engineering design technical measure > > construction (2003) Regulation DesignOther specifications also have requirements, but are too scattered to find easily
