Description

Root-blocking and waterproof structure for green roof planting

technical field

The utility model relates to a waterproof structure for roof greening, in particular to a root-blocking waterproof structure for roof greening and planting.

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 root-blocking waterproof structure for roof greening and planting, 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 root-blocking waterproof structure of the roof greening planting includes a waterproof coiled material layer laid on the roof, a steel concrete leveling layer poured on the waterproof coiled material layer, a drainage board laid on the steel concrete leveling layer located in the planting area, The polyester non-woven filter layer laid on the drainage board, and the lightweight planting soil covered on the polyester non-woven filter layer.

The drainage board adopts a HIPS drainage board, and a plurality of conical bosses are uniformly arranged on the board surface, and water storage nests are formed between the conical bosses.

Perlite is filled in the water storage nest.

The waterproof coiled material layer adopts SBS modified asphalt waterproof coiled material with two-layer composite copper base.

The steel concrete leveling layer has a thickness of 50mm and is equipped with a reinforcing mesh inside.

The anti-height of the four sides of the polyester non-woven fabric water filter layer is 100mm.

In the above technical solution, the root-blocking waterproof structure for green roof planting of the present invention includes a waterproof coiled material layer laid on the roof, a steel concrete leveling layer poured on the waterproof coiled material layer, and a steel concrete leveling layer laid on the planting area. The drainage board on the steel concrete leveling layer, the polyester non-woven fabric water filter layer laid on the drain board, and the lightweight planting soil covered on the polyester non-woven fabric water filter layer. Drainage boards are used to replace the traditional cobblestone water filter layer, which can achieve beneficial effects such as drainage, energy saving, investment saving, and building load reduction. In addition, the SBS modified asphalt root waterproofing membrane with composite copper base is used. When the plant roots are exposed to the copper ions in the composite copper matrix, they will turn to find other ways to continue to grow, so as to achieve effective root resistance.

Detailed ways

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

Please refer to Fig. 1 to Fig. 2, the root-blocking waterproof structure of the roof greening planting of the present utility model is from bottom to top, mainly including the waterproof coiled material layer 10 laid on the roof 1, the waterproof coiled material layer 10 poured on the Steel concrete leveling layer 11, drainage board 12 laid on the steel concrete leveling layer 11 located in the planting area, polyester non-woven fabric water filter layer 13 laid on the drainage board 12, polyester non-woven fabric water filter layer Light planting soil 14 on layer 13.

in:

The waterproof membrane layer 10 can be formed by laying SBS modified asphalt waterproof membrane with two layers of composite copper base. The SBS modified asphalt waterproofing membrane using the composite copper base not only has the advantages of waterproof and anti-leakage, but also has several other advantages:

1. When the plant roots come into contact with the copper ions in the composite copper base, they will turn to find other ways to continue to grow, thus effectively preventing the roots;

2. Copper and polyester conform to each other, maintaining the performance of the polyester base, the tensile strength reaches 800N/5cm, and the elongation reaches 40%;

3. The elongation rate is large, so that the material has an ideal anti-deformation ability and can adapt to the deformation of different structures;

4. High tensile strength is beneficial for the material to adapt to the deformation of the structure and avoid material tearing.

The steel concrete leveling layer 11 has a thickness of 50mm, and is equipped with a steel mesh inside to increase the tensile strength.

The drainage board 12 can be a HIPS drainage board 12, and a plurality of conical bosses 121 are evenly arranged on the board surface, so that a water storage nest 122 is formed between the conical bosses 121, and the drainage of the channels is smooth. A small amount of perlite can be filled in the water storage nest 122 on the plate, and the soil-proof layer needs to suppress the water storage nest 122 and cover the water filter layer to prevent the soil particles from passing through, thereby avoiding the blockage of the drainage channel.

Described polyester non-woven fabric water filter layer 13 adopts 120g/m ² The polyester non-woven fabric is laid and forms, and its surroundings need to be reversed, and the height of the upper reverse is 100mm (A place among Fig. 1).

To sum up, the root-blocking waterproof structure of the roof green planting of the present utility model is used to replace the traditional cobblestone water filter layer by using the drainage board 12, which can play a role in drainage, energy saving, investment saving, and reduction of building loads. In addition, when the SBS modified asphalt root waterproofing membrane with composite copper base is used, when the plant roots come into contact with the copper ions in the composite copper base, they will turn to find other ways to continue to grow, so as to achieve effective root resistance. It is used for high-altitude green planting construction on various roofs or other buildings.

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.
