Technical Field

[0001] The utility model relates to a drainage structure, in particular to a drainage structure applied to a planting roof. Background Art

[0002] With the development of cities, urban greening issues have attracted more and more attention. As a new type of greening method, green roofs can not only beautify cities, but also protect the environment, save energy and reduce emissions.

[0003] Green roofs can effectively isolate outdoor natural factors such as high temperature, low temperature, wind, rain, etc., improve the insulation performance of houses, and extend the life of houses. Therefore, they are widely used in the construction industry. However, with traditional construction methods, the structural stability of green roofs is poor, and it is difficult to ensure that there will be no leakage during the service life. Therefore, there is a need for a drainage structure that can ensure smooth drainage of green roofs to prevent blockage and leakage. Utility Model Content

[0021] Example

[0022] Reference Figure 1 and Figure 2The present embodiment relates to a drainage structure applied to a green roof, including a structural layer 1, a water circulation system 2 arranged on the structural layer 1, masonry 3 stacked on both sides of the water circulation system 2, and a drainage pipe 4 buried at the bottom of the masonry 3; the drainage pipe 4 is connected to both sides of the masonry 3; the pit on the side of the masonry 3 is filled with planting soil 5, and plants are planted on the surface of the planting soil 5.

[0023] The structure piles up masonry 3 on both sides of the water circulation system 2 to form a drainage ditch 23, so that excess rainwater in the planting soil 5 is discharged into the drainage ditch 23 through the drainage pipe 4 and is collected by the water circulation system 2, thereby preventing the problem of excessive rainwater in the planting soil 5 remaining for a long time and causing leakage.

[0024] The upper ends of the masonry 3 on both sides of the water circulation system 2 are provided with perforated covers 6 for rainwater to flow into the gutter. Rainwater can flow into the gutter through the perforated covers 6 and be collected by the water circulation system 2, thereby preventing excessive rainwater from accumulating on the upper surface of the plants, allowing the rainwater to be quickly discharged to prevent leakage problems.

[0025] The water circulation system 2 is arranged on the structural layer 1 through the waterproof sealing paste 7 to prevent rainwater in the drainage ditch from leaking through the gap between the water circulation system 2 and the structural layer 1.

[0026] A drainage board 8 is provided at the outer bottom of the masonry 3, and the drainage board 8 is provided on the upper part of the drainage pipe 4. The drainage board 8 is used to receive excess rainwater in the planting soil 5, so that the rainwater is collected by the drainage board 8 and discharged into the drainage ditch 23 through the drainage pipe 4, and recycled by the water circulation system 2.

[0027] An isolation layer 9 is provided between the drainage board 8 and the planting soil 5. The isolation layer 9 serves to prevent the root system from damaging the structure and to protect the roof layer.

[0028] A graded stone 10 is provided between the drainage board 8 and the planting soil 5. The graded stone 10 has good water permeability, which can make rainwater flow onto the drainage board 8 more easily, thereby better collecting excess rainwater in the planting soil 5.

[0029] One end of the drain pipe 4 which is the same as the outer side of the masonry 3 is provided with a filter layer 11. The filter layer 11 can prevent the drain pipe 4 from being blocked by mud.

[0030] An angle iron 12 is fixed to the upper end of the masonry 3, and the cover plate 6 with holes can be opened or covered on the angle iron 12. A plurality of angle irons 12 form a wellhead, and the cover plate 6 with holes can be opened or covered on the wellhead. The cover plate 6 with holes can be a grate.

[0031] The angle iron 12 is fixed to the upper end of the masonry 3 through the steel bar 13. One end of the steel bar 13 is embedded in the upper end of the masonry 3, and the other end is connected to the angle iron 12, so that the angle iron 12 is fixed to the masonry 3.

[0032] The construction process of this utility model is as follows:

[0033] Before the construction of the planted roof, the water circulation system 2 is constructed according to the characteristics of the site. First, the building structure layer 100 is completed, and then the water circulation system 2 is waterproofed and sealed with a waterproof sealant. When installing the embedded drain pipe 4, the drainage board 8 is first installed on the upper part of the drain pipe 4 to receive excess rainwater so that the rainwater can be recycled. After the water circulation system 2 itself is waterproofed, the masonry 3 is built on both sides, and the drain pipe 4 is embedded; after reaching the height of the masonry, the masonry is stopped, and then the masonry structure is waterproofed; graded stones 10 are added at the contact surface with the planting soil 5 for drainage treatment, and an isolation layer 9 is added for differentiation and isolation; the filter layer 11 is used for filtration, and after the treatment is completed, it is connected with the embedded drain pipe 4 to realize the collection of rainwater. The built drainage ditch 23 has pre-embedded angle irons 12 and steel bars 13 on the top, and is connected to the upper capping material 16 with concrete 14 and cement mortar 15; after the entire structure is completed, the decorative surface can be constructed, and finally the planting soil 5 is piled and leveled; after the construction is completed, the vegetation can be planted.

[0034] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
