Distance between the entrance and exit of underground pedestrian passage and the building

If it refers to the distance between the pedestrian exit and the building, the residential entrance (motor vehicle entrance and pedestrian entrance) cannot be designed according to an independent law alone.

Generally speaking, we should refer to the following aspects: 1. Consider the following normative factors: Article 4. 1.5 of General Principles for Design of Civil Buildings (GB50352-2005) stipulates that "the location of motor vehicle entrances and exits in the base should meet the following requirements: the intersection of main roads in large and medium-sized cities should not be less than 70 meters away from the intersection of road red lines".

Article 8.0.5. 1 Code for Planning and Design of Urban Residential Areas (GB 50 180-93 (2002 Edition)) stipulates: "There should be at least two residents on the main roads in residential areas; The main roads in residential areas should be connected with peripheral roads in at least two directions; The distance between the motor vehicle lane and the migrant population should not be less than 150m. When the length of the building along the street exceeds 150m, a fire truck passage of not less than 4m×4m shall be set. The spacing between pedestrian exits should not exceed 80 meters. When the building length exceeds 80m, a pedestrian passage should be added on the ground floor. 2. Considering the late property management factors, reasonably arrange the number of entrances and exits, and control the labor cost of security. 3. Consider the flow of people and vehicles near the entrance and exit of the residential area, and avoid arranging the entrance and exit in the position of traffic congestion. At the same time, it is necessary to avoid traffic accident-prone areas, which is conducive to the timely arrival of fire, medical, public security and other vehicles in an emergency. 4. Consider the convenience of residents' travel, such as the actual demand of getting to the bus stop quickly.
