The design and planning of the old residential parking lot, and the construction scheme of the underground parking lot?

Construction scheme of lining underground parking lot:

I. Standard parking space dimensions, underground parking space dimensions, and the application of standard parking space dimensions in parking lots.

Two, the standard size of the parking space (refers to the private car space in the community, garage, how much is the size of the private car space)

1. Straight parking, the standard size of parking space is 2.5m * 5.3m.

2. The standard size of the parking space is 2.8 meters *6 meters, and the inclination Angle is 60 ° 3. Proximity barrier marker: A marker used to indicate the presence of a fixed obstacle on the road surface

1. Obstacle in middle of dual carriageway

2. Obstacle in the middle of four lanes

3. Obstacle in the middle of the second lane in the same direction

Deceleration line: it is used to remind you that this section should slow down and drive carefully.

China's building code on the garage, parking lot design standards are more complex, divided into four levels, although there is no provision for the so-called "standard parking space size", but stipulates the corresponding minimum to meet the size. If the car is not 6 meters long and the car width is not more than 1.8 meters, the distance between the car and the car is not less than 0.5 meters, the distance between the car and the wall and the parking end is not less than 0.5 meters; If the length of the car is more than 6 meters but not more than 8 meters, and the width of the car is more than 1.8 meters but not more than 2.2 meters, the distance between the cars is not less than 0.7 meters, etc. The corresponding specification of the entry section is to meet the need of one vehicle turning around once, which actually provides different dimensions for different types of parking lots. Therefore, for parking lots mainly for small cars, the size of the parking space is mostly 2.5-2.7 ×5~6, and the width of the single-lane rotary lane is not less than 3.5 meters, and the double-lane is not less than 5 meters. In addition, the parking lot is marked with a special parking lot marked with special paint, otherwise it will lead to reflective, thus affecting the identification of the driver, so as to eventually lead to traffic accidents. Special parking lot marking special marking process is divided into hot melt and room temperature cold coating.

Hotmelt line:

1, film thickness: 1.2-1.5mm; No adhesion, drying time less than 5min;

2. Appearance: the coating is clean and bright, resistant to the sun and temperature difference, does not change color, strong reflectance at night.

3. Traffic markings are safety facilities composed of road markings, arrows, text, elevation markings and roadside contour marks, etc., which are used to control and guide traffic. Cold coating line: 1, film thickness: 0.12-0.15mm; No stick tire, drying time less than 30min;

2. Appearance: uniform coating thickness, clear color, sun resistance and temperature difference, no discoloration.

3. Traffic markings are safety facilities composed of road markings, arrows, text, elevation markings and roadside contour marks, etc., which are used to control and guide traffic.
