Background

Along with the development of urbanization, the soil that can plant green planting now is less relatively, in order to let the environment in city more graceful, carries out green planting on the roof of building gradually and plants, but current roof structure, it is when planting green planting, and waterproof and watering are the key that hinders green planting growth in roof, and current roof structure can not satisfy the planting of green planting of large tracts of land.

Disclosure of Invention

To the above problem, the utility model provides a green roof of environment-friendly, it plants green planting on a large scale on the roof, has promoted the green coverage rate of planting in city, and has done the waterproof on roof, ensures that green planting can self-absorption water, guarantees green healthy growth of planting.

An environment-friendly green roof, its characterized in that: it includes the building roofing, the periphery of building roofing is provided with the wall body, the central zone of building roofing is vegetation coverage area, vegetation coverage area's periphery is provided with the brick wall, the height of brick wall is higher than the planting soil layer of vegetation coverage area's top layer, the bottom of brick wall is provided with the outlet, the outlet communicate to the escape canal that forms between brick wall and the wall body, be provided with the water inlet of at least one perpendicular rainwater fill of arranging in the region of escape canal, vegetation coverage area has arranged planting soil layer, ecological porous fiber cotton layer, geotechnological cloth, drainage blanket, root resistance puncture waterproof layer from the top down in order, the drainage blanket communicates to the escape canal through the outlet.

It is further characterized in that:

an overflow port is arranged at the position of the wall body, which is not higher than the upper plane of the planting soil layer, so that water in the drainage ditch can overflow in time when the rainwater hopper drains unsmoothly;

the top of the building roof is sequentially provided with a leveling layer, a common waterproof layer and a root penetration resistant waterproof layer from bottom to top;

the rabbets of the common waterproof layer and the root penetration resistant waterproof layer respectively extend to the lower part of the wall body corresponding to the overflow port, so that the waterproof performance of the whole building roof is ensured to be good;

the thickness of the root puncture resistant waterproof layer is 8 mm;

the thickness of the drainage layer is 11 mm;

the ecological porous fiber cotton layer and the planting soil layer are the same in thickness and are both 40 mm.

After adopting above-mentioned technical scheme, green planting is planted in planting the soil layer, the cotton layer of ecological porous fibre adsorbs the rainwater of living rainy day, reach the saturation back, the rainwater passes through the rainwater fill behind the drainage ditch entering along the drainage blanket, when dry fine day, the intraformational root of planting the soil layer plant absorbs the intraformational water of ecological porous fibre cotton, carry out healthy growth, it plants green planting on a large scale on the roof, the green coverage rate of planting in city has been promoted, and the waterproof on roof has been done, ensure that green planting can be from absorbing water, guarantee the healthy growth of green planting.

Drawings

Fig. 1 is a schematic top view structure of the present invention;

FIG. 2 is a schematic view of section A-A of FIG. 1;

the names corresponding to the sequence numbers in the figure are as follows:

the ecological planting and greening system comprises a building roof 1, a wall 2, a vegetation coverage area 3, a planting soil layer 31, an ecological porous fiber cotton layer 32, a permeable geotextile 33, a drainage layer 34, a root-piercing-resistant waterproof layer 35, a brick wall 4, a drainage opening 5, a drainage ditch 6, a rainwater hopper 7, an overflow opening 8, a leveling layer 9, a common waterproof layer 10 and a green plant 11.

Detailed Description

An environment-friendly green roof, as shown in fig. 1 and fig. 2: it includes building roof 1, the periphery of building roof 1 is provided with wall body 2, the central zone of building roof 1 is vegetation cover area 3, the periphery of vegetation cover area 3 is provided with brick wall 4, the planting soil layer 31 of the top layer that highly is higher than vegetation cover area 3 of brick wall 4, the bottom of brick wall 4 is provided with outlet 5, outlet 5 communicates to the escape canal 6 that forms between brick wall 4 and the wall body 2, be provided with the water inlet of at least one perpendicular rainwater fill 7 of arranging in the region of escape canal 6, vegetation cover area 3 has arranged planting soil layer 31 from the top down in order, ecological porous fiber cotton layer 32, the geotechnological cloth 33 that permeates water, drainage blanket 34, root resistance waterproof layer 35, drainage blanket 34 communicates to escape canal 6 through outlet 5.

An overflow port 8 is arranged at the position of the wall body 2 which is not higher than the upper plane of the planting soil layer 31, and ensures that water in the drainage ditch 6 overflows in time when the rainwater hopper 7 drains unsmoothly;
