Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 and 2, a multi-azimuth drainage grass planting ditch comprises a grass planting ditch body, a row of curbstones 1 are arranged on road surfaces 3 at two sides of the grass planting ditch body, hydrophobic holes 2 are formed at the bottom ends of the curbstones 1, the number and the intervals of the hydrophobic holes 2 are determined according to actual conditions, and rainwater on the road surfaces 3 is drained into the grass planting ditch through the hydrophobic holes 2; this internal pond 5 of keeping in that has buried a plurality of open-tops underground of grass ditch, 5 openings of every pond of keeping in lean on with the bottom of a hydrophobic hole 2 along leaning on under being close to one side on road surface 3, pond 5 and the hydrophobic hole 2 one-to-one of keeping in promptly, the rainwater through hydrophobic hole 2 is discharged into and is kept in pond 5, pond 5 of keeping in is through burying underground in this internal conduit 4 intercommunication municipal rainwater pipeline of grass ditch, can directly discharge the rainwater into municipal rainwater pipeline through conduit 4, the drainage is efficient.

The water inlet end of the water conveying pipeline 4 is provided with the filtering device 6 which can filter rainwater, as shown in figure 3, the filtering device 6 can filter the rainwater, the water outlet end of the water conveying pipeline 4 is provided with the anti-reverse irrigation device 14 which is a one-way door and can be opened and closed in one way, and when the rainfall is too large, the rainwater discharged by municipal administration can be prevented from being reversely irrigated.

The grass planting ditch comprises a ditch body, wherein an intercepting scour prevention layer, a planting layer, a first purification layer, a second water purification layer and a reservoir are sequentially arranged on the ditch body from top to bottom, a one-way reverse osmosis pipe 12 is laid in the second water purification layer, the reverse osmosis pipe 12 is communicated with the reservoir, and the reverse osmosis pipe 12 is used for discharging water purified by the water purification layer into the reservoir 13 through an osmotic pressure principle and irrigating vegetation on a road surface 3; wherein the interception scour prevention layer is a cobblestone layer 7, the planting layer is a soil layer 8, the first purification layer is a charcoal layer 10, and the second water purification layer is a gravel layer 11; in order to prevent soil particles from sinking down, a geotextile 9 is laid between the lower soil layer 8 and the charcoal layer 10.

Above-mentioned pond 5 of keeping in buries in the interception scour prevention in situ, and conduit 4 buries in the second water purification layer underground, and the second water purification layer is worn out to conduit 4's the end of intaking, passes first purification layer in proper order and plants the layer, penetrates interception scour prevention layer and 5 intercommunications of pond of keeping in.

When a small amount of rainfall occurs, part of rainwater falling on the cobblestone layer 7 is absorbed by vegetation and partially seeps downwards, the rainwater is purified by the purification layer and then is stored in the reservoir 13 through the reverse seepage pipe 12, the rainwater falling on the road surface 3 is drained to the temporary storage pool 5 through the drainage holes 2, and the temporary storage pool 5 is directly drained to a municipal rainwater pipeline through the water pipeline 4; during a large amount of rainfall, the rainwater part that falls into cobblestone layer 7 is absorbed by the vegetation, and the part is oozed down, is deposited in cistern 13 through anti-infiltration pipe 12 after purifying the layer, and the rainwater that falls into road surface 3 passes through hydrophobic hole 2 to the pond 5 drainage of keeping in, and pond 5 of keeping in directly drains to municipal rainwater pipeline through conduit 4, if the pond 5 of keeping in amount of exceeding the opening, the rainwater of overflow outflow directly discharges into cobblestone layer 7.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
