Specific embodiment

Illustrate specific embodiment of the present utility model with reference to the accompanying drawings and examples, but following embodiment only uses It is described in detail the utility model, does not limit the scope of the utility model in any way.Involved in following embodiment The devices such as unit module components, structure, mechanism or sensor are then unless otherwise instructed conventional commercial product.

Embodiment: as Figure 1-Figure 5, a kind of roof greening circulation, including roof 1, greening unit 2 and circulation Water tank 3, multiple greening units 2 are obliquely installed along 1 gradient direction of roof on roof 1 with same intervals, and the fixation of cyclic water tank 3 is set It is placed in 1 side of roof, is equipped with sparge pipe 4 in the top that greening unit 2 is located at high-order one end, sparge pipe 4 is equipped with spray head 5, And one end of sparge pipe 4 is connected with the water circulating pump (not shown) being set in cyclic water tank 3, is located at low level in greening unit 2 The roof 1 of one end is equipped with guiding gutter 6, and guiding gutter 6 is connected after running through 1 side wall of roof with the water inlet of cyclic water tank 3.

In the present embodiment, greening unit 2 is trapezoidal greening groove 7 including upper end opening, cross section, in the greening groove 7 Successively along roof, 1 gradient direction is provided tiltedly with waterproof layer 8, drainage layer 9, water conservation layer 10, filter layer 11 and plantation layer from top to bottom 12, plantation 12 upper surface of layer is 1.5~3.5cm lower than 7 cell wall of greening groove；Drainage rack 13, drainage are equipped in the upper surface of drainage layer 9 Frame 13 is equipped with several drainage troughs 14, is equipped with several diversion pipes 15 in water conservation layer 10, which is located at drainage trough 14 Surface；The both ends of greening groove 7 are equipped with baffle 16, and the upper surface of baffle 16 is 1~1.5cm higher than plantation layer 12, and greening groove 7 The upper baffle 16 in low level one end is equipped with conduction hole 17 corresponding with drainage trough 14, which is located at guiding gutter 6 Top.

Cyclic water tank 3 includes water storage cavity 18 and precipitating chamber 19, and water storage cavity 18 and precipitating 19 volumetric ratio of chamber are 5:1, water storage cavity Partition 20 is equipped between 18 and precipitating chamber 19, the top of partition 20 is equipped with strainer 21.

The operate with method of above-mentioned roof greening circulation is as follows:

In rainy season, most of flow to along the gradient of the rainwater afforested in unit 2 afforests the lower one end of unit 2, and It after rainwater covers baffle 16, overflows in guiding gutter 6, is flowed into cyclic water tank 3 further along guiding gutter 6, come together in cyclic water tank 3 Interior rainwater is first precipitated in precipitating chamber 19, and sediment deposition passes through in precipitating 19 bottom of chamber, the rainwater on precipitating 19 top of chamber Enter in water storage cavity 18 after the filtering of strainer 21 and stores, the irrigation for later period greening unit 2；Meanwhile the rain of fraction Water infiltrates into downwards 10 top of water conservation layer, and a part is stored in plantation layer 12 in the part rainwater, for green plants Growth, a part pass through water conservation layer 10 by diversion pipe 15 and flow into the drainage trough 14 on drainage rack 13, and along drainage trough 14 Conduction hole 17 on baffle 16 flows into guiding gutter 6.

In dry season, the rainwater in water storage cavity 18 enters in sparge pipe 4 under the action of water circulating pump, and by spray head 5 Spray function is in high-order one end to greening unit 2 and carries out trickle irrigation, is seeped to plantation layer 12 under water a part that trickle irrigation comes out For the growth of green plants, other end flowing of a part along the gradient to greening unit 2, to complete to entire greening unit 2 irrigation.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field Other modifications or equivalent replacement that those of ordinary skill makes the technical solution of the utility model, it is practical without departing from this The spirit and scope of new technique scheme should all cover in the scope of the claims of the utility model.
