The director asked the question the first two days. I went back to the Internet and checked. But not the correct answer, one said, "fire lane width of not less than 3.5 meters, the distance from the top of the high-rise building is 4 meters, generally 5 meters."." There is a saying "planning version 2006 requires all fire lane width of 3.5 meters to 4 meters". Who knows the answer to the question?. The best fire brigade's brother, and their answers should not be wrong.
The ring fire lane should have at least two lanes connected to other lanes. The end fire lane shall be provided with a return lane or a return field of no less than 12 * 12m2. The size of the return field used for large fire engines shall not be less than 15 * 15m2. The fire lane pipe and drain should be able to withstand the pressure of large fire truck.
The fire lane width should not be less than 3.5m, over the road in case of pipe rack, stack frame and other obstacles, the height of not less than 4m.
The fire lane through the building of the door, the height and width of not less than 4m; gate stack between the width of not less than 3.5m. ?Be careful：Fire lane need to meet the fire fighting work, therefore, fire lane layout should consider fire fighting work, a certain distance from the building is required.
