Description

Drainage system for green roof planting area

technical field

The utility model relates to a roof greening drainage structure, in particular to a drainage system for a roof greening planting area.

Background technique

Due to the rapid development of the city, thousands of high-rise buildings have been erected one after another, the city has taken on a new look, and there is a modern urban atmosphere everywhere. However, the development of cities has also greatly reduced the area of green areas, and the heat island effect has become more and more significant.

Therefore, urbanites living in cities generally like to travel, especially those living in metropolises prefer to travel and get in touch with nature. Green mountains and green waters, red flowers and green leaves, strong negative ions, and fresh air with a little grass smell are the longing and yearning of every urbanite.

Waterproofing and drainage treatment are one of the necessary prerequisites for roof greening. The traditional drainage method uses masonry tiles (such as pebbles, etc.) Increased the load of the building, but also has a certain construction difficulty.

Utility model content

In view of the above-mentioned shortcomings in the prior art, the purpose of this utility model is to provide a drainage system for roof greening and planting areas, which can realize drainage, energy saving, investment saving, and reduce the load of buildings.

In order to achieve the above object, the utility model adopts the following technical solutions:

The drainage system of the roof green planting area includes, from bottom to top, a waterproof layer laid on the roof, a steel concrete leveling layer poured on the waterproof membrane layer, a ceramsite drainage layer laid on the steel concrete leveling layer, The polyester non-woven fabric water filter layer laid on the ceramsite drainage layer, the lightweight planting soil layer covered on the polyester non-woven fabric water filter layer, and multiple drainage blind pipes are arranged in the ceramsite drainage layer.

The average distance between the blind drainage pipes is 2m.

The ceramsite diameter of the ceramsite drainage layer is 8-12mm.

The thickness of the ceramsite drainage layer is 120mm.

The output ends of the blind drainage pipes are collectively connected to the gutter located on one side of the planting area.

In the above technical solution, the drainage system of the green roof planting area of the present utility model includes, from bottom to top, a waterproof layer laid on the roof, a steel concrete leveling layer poured on the waterproof coil layer, and a steel concrete leveling layer laid on the steel concrete layer. The ceramsite drainage layer on the leveling layer, the polyester non-woven fabric water filter layer laid on the ceramsite drainage layer, the light planting soil layer covered on the polyester non-woven fabric water filter layer, and the ceramsite drainage layer There are also multiple drainage blind pipes arranged. By using ceramsite as the drainage layer, the load on the roof can be reduced, and the filling amount of planting soil can be increased, thereby expanding the load capacity of the roof. In addition, by placing a drainage blind pipe in the ceramsite layer, rainwater or irrigation water enters the blind pipe through the ceramsite drainage layer, and then is discharged into the gutter through the blind pipe, so as to realize effective drainage of green roofs.

Description of drawings

Fig. 1 is the structural cross-sectional view of the drainage system of the green roof planting area of the present invention;

Fig. 2 is a partial sectional view of the drainage system of the present invention.

Detailed ways

The technical scheme of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

Please combine with Fig. 1-Fig. 2, the drainage system of the green roof planting area of the present utility model is from bottom to top, mainly including the waterproof layer 2 laid on the roof 1, and the steel concrete leveling layer poured on the waterproof coiled material layer 3. The ceramsite drainage layer 4 laid on the steel concrete leveling layer 3, the polyester non-woven fabric water filter layer 5 laid on the ceramsite drainage layer 4, the polyester non-woven fabric water filter layer 5 covered The light planting soil layer 6, and a row of multiple blind drainage pipes 7 are also arranged in the ceramsite drainage layer 4.

The use of ceramsite as the drainage layer to replace the original cobblestone and other materials is based on its good drainage performance, which is lighter, can reduce the load on the roof 1, and can increase the filling amount of planting soil by 7-8 cm , thereby expanding the load capacity of the roof 1.

Wherein, the diameter of the ceramsite used in the ceramsite drainage layer 4 is 8-12mm, and the thickness of the ceramsite drainage layer 4 is 120mm.

The average interval between the blind drainage pipes 7 is 2m, and the output ends of the blind drainage pipes 7 are collectively connected to the gutter located on one side of the planting area, so that the rainwater or irrigation water that enters the blind pipes through the ceramsite drainage layer can be collected. , concentratedly drained into the gutter by the blind pipe, so as to realize the effective drainage of the roof 1 greenery.

In addition, it is worth noting that the construction sequence of the drainage layer should be carried out step by step from the inside to the outside, first place the drainage blind pipe 7, then spread ceramsite, cover with polyester non-woven fabric and then cover with soil, preferably 5m Advance slowly. It cannot be paved all at one time and then covered with soil in a concentrated manner, which will easily damage the drainage system and eventually affect drainage.

In summary, adopting the drainage system of the roof 1 green planting area of the present utility model can well reduce the load on the roof 1, and can increase the filling amount of the planting soil. In addition, by placing the drainage system in the ceramsite layer In the blind pipe, rainwater or irrigation water enters the blind pipe through the ceramsite, and then is discharged into the gutter through the blind pipe, so as to realize the effective drainage of the roof 1 greenery.

Those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the utility model, rather than as a limitation to the utility model, as long as within the spirit of the utility model, the above-mentioned The changes and modifications of the embodiments will all fall within the scope of the claims of the present utility model.
