The green belt 1 adjacent to the building includes multiple green areas. The green areas correspond to the windows of the occupants on the first floor of the building, and the spaces between the green areas correspond to the unit doors, which are the access areas of the unit doors. For example, if there are five units in total, there can be six Block green area.

There are green belts 1 on both sides of the access road to ensure the greening construction of the community and improve the environment of the community. At the same time, there is a first waterproof cloth 1.3 and a first drainage pipe 1.5, etc., the drainage effect is good, whether it is heavy rain or plant watering, it not only avoids the plant from being flooded, but also drains the water in time to avoid the accumulation of water near the building and avoid the first floor being too humid .

The access road includes the undisturbed soil layer 4.1, the second cushion layer 4.2, the second water-collecting layer 4.4, the drainage asphalt layer 4.5 and the pavement layer laid in sequence from bottom to top. There is a second waterproof cloth 4.3, the second water collecting layer 4.4 is in the shape of an inverted triangle, and its bottom edge is the same as the width of the permeable cement stabilized gravel layer. A transverse drainage pipe 6 is arranged in the cushion layer 4.2, and the longitudinal water collecting pipe 5 is communicated with the drainage ditch 2 through the transverse drainage pipe 6. The transverse drains 6 are located in the first water collecting layer 1.2 and/or in the second cushion layer 4.2. The longitudinal water collecting pipes 5 are located in the first water collecting layer 1.2 and/or in the second cushion layer 4.2. The longitudinal water collecting pipe 5 and the horizontal drainage pipe 6 are all pressure-resistant pipes with a diameter of 75 to 150 mm. The surface of the vertical water collecting pipe 5 has holes of 10 to 15 mm in diameter, and the opening rate is 20 to 35%. The longitudinal water collecting pipe 5 is covered with nylon mesh and Geotextile. The interval between the horizontal drainage pipes 6 is 0.8m. Drainage asphalt layer 4.5 adopts multi-void drainage asphalt mixture PAC-13, the second cushion layer 4.2 is filled with pond slag, the second aquifer layer 4.4 is a gravel aquifer layer, or the second aquifer layer 4.4 is compacted with gravel and rubble made.

The pavement layer includes sidewalks and two wheel lanes. The sidewalks include a permeable cement mortar layer 7.1 laid on the drainage asphalt layer 4.5 and a permeable brick layer 7.2 laid on the permeable cement mortar layer 7.1. The permeable brick layer 7.2 is between the bricks. The gap is 2.5-3.5cm, and the gap is filled with cement mortar; the wheel track includes the medium-grain asphalt concrete layer 8.1 laid on the drainage asphalt layer 4.5 and the fine-grain asphalt concrete layer laid on the medium-grain asphalt concrete layer 8.1. 8.2.
