DETAILED DESCRIPTION

[0026] The water storage type roof planting structure will be specifically introduced below in combination with the drawings and specific embodiments.

[0027] The water storage type roof planting structure comprises a water storage unit 3, loose material 4 and water filtering layer 5 arranged in a planting pool 1.

[0028] The planting pool 1 is built on the building roof deck with the existing waterproof layer 2, and the inner wall and bottom of the planting pool 1 are provided with the waterproof layer 2, and 2cm-thick waterproof mortar can be applied.

[0029] First, the water storage unit 3 layer is laid at the bottom of the planting pool 1, specifically: a single row of water storage units 3 is laid at both ends of the planting pool 1, and multiple rows of closely connected water storage units 3 are laid at the middle of the planting pool 1. The water storage units 3 at the middle are at least 2 rows, and preferably 3 rows. And there are intervals between the single row and multiple rows of water storage units 3, and between the multiple rows and multiple rows of water storage units 3. Preferably, the size of the single row of water storage units 3 is 90×25×8cm, and the interval is preferably 30cm.

[0030] The water storage unit 3 is a hollow box, the top surface is a closed cover plate, and a plurality of water inlet holes 9 are arranged on the cover plate. Preferably, the water inlet hole 9 is a circular hole with a diameter of 2cm, and the center distance between adjacent two circular holes is 6cm, which facilitates the water in the soil to seep into the cavity of the water storage unit 3. A plurality of parallel partitions 11 are suspended on the bottom surface of the cover plate, which divide the inner cavity of the water storage unit 3 into a plurality of water storage unit cells. And the height of the partition 11 is less than the height of the box, that is, the bottom end of the partition 11 is suspended, and adjacent unit cells are communicated through the bottom end of the partition 11. Preferably, the suspended height is 3cm. The water outlet hole 10 is arranged on the side surface of the box, and preferably, each unit cell is respectively provided with a water outlet hole 10, and the water outlet hole 10 is preferably a slot with a size of 3×5cm.

[0031] Preferably, the size of the water storage unit 3 is 90×75×8cm, and the material can be plastic, metal, etc., which is formed by mold or welded in the factory at one time.

[0032] The side wall of the planting pool 1 is provided with a plurality of drainage openings 8, and the bottom of the drainage opening 8 is flush with the top of the water storage unit 3 layer. And in the planting pool 1, a plurality of filter stones 7, preferably gravel, are stacked at the drainage opening, which facilitates the water flow into the drainage opening 8 and does not form blockage. Preferably, the drainage opening 8 is a plastic drainage pipe with a diameter of 5cm, or a square drainage hole with a size of 4-5cm.

[0033] The filter layer 5 is laid on the water storage unit 3, gravel and exposed pool bottom, and extends upward along the pool wall side to the filling height; the filter layer 5 can be selected from non-woven fabric or other water-permeable materials. The space between the water storage units 3 (the top of the filter layer 5) is filled with loose material 4, which can be selected from coal cinder or loose sandy soil.

[0034] The planting soil 6 is filled on the top of the filter layer 5 and the loose material 4. The filter layer 5 is used to prevent the planting soil 6 from flowing into the water storage unit 3. The water in the water storage unit 3 can penetrate into the planting soil 6 through the capillary action of the loose material 4.
