Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description. In the preferred embodiments, the terms "upper", "lower", "left", "right", "middle" and "a" are used for the sake of clarity only, and are not intended to limit the scope of the invention, its relative relationship between the terms and their derivatives, and the scope of the invention should be understood as being limited by the claims.

As shown in figure 1, the utility model provides an ecological grass planting ditch system in sponge city, which comprises a planting soil layer 1, a filter layer 2 and an original soil layer 3 which are arranged from top to bottom in sequence, a penetration pipe 4 which is arranged in the filter layer 2 and the planting soil layer 1, and a drain pipe 5 which is arranged in the original soil layer 3, wherein the surface of the planting soil layer 1 is sunken downwards to form a grass ditch for planting vegetation, one end of the penetration pipe 4 penetrates out of the planting soil layer 1 upwards to form a water overflow port 6, the other end of the penetration pipe 4 is communicated with the drain pipe 5 downwards, the pipe wall of the penetration pipe 4 in the filter layer 2 is provided with a plurality of small holes, surface runoff at two sides of the grass ditch can be gathered in the grass ditch when raining, the planting soil layer 1, the filter layer 2, and the vegetation planted on the planting soil layer 1 can effectively relieve the rain drainage and storage, and can treat runoff pollution. This ecological grass planting ditch system in sponge city's simple structure, area is little, and easy to maintain, and can use in urban landscape design in a large number, moreover, this ecological grass planting ditch system in sponge city has not only satisfied the demand of drainage, has ornamental value moreover.

The utility model discloses ecological grass planting ditch system in sponge city's theory of operation as follows:

when the rainwater amount is less, namely the rainwater gathered in the grass ditch is less than the infiltration speed of the rainwater in the grass ditch, all the rainwater infiltrated in the filter layer 2 permeates into the permeation tube 4 again and is finally discharged through the drain pipe 5; when the rainwater volume is great, assemble when the rainwater that gathers in the grass ditch promptly is greater than the infiltration speed of rainwater in the grass ditch, partial rainwater forms ponding in the grass ditch, can flow into gap 6 when ponding height reaches gap 6, makes ponding discharge fast to avoid appearing the waterlogging. The drain pipe 5 may be connected to a municipal sewage irrigation canal, although it is also possible to drain water to an external river or pond.

In a concrete implementation, filter layer 2 is gravel, cobble, or the mixture of gravel and cobble, and this filter layer 2 clearance is big, and retaining capacity is strong to can do benefit to the growth of planting vegetation on soil horizon 1, gravel or cobble with be formed with the infiltration clearance between the aperture of infiltration pipe 4, when the rainfall is big, do benefit to rainwater infiltration pipe 4, thereby arrange outside the acceleration rainwater, prevent ponding on the grass ditch. The vertical setting of infiltration pipe 4, and the quantity of infiltration pipe 4 is many, and many infiltration pipes 4 set up along the length direction interval of grass ditch, set up the interval of infiltration pipe 4 according to the drainage ability selectivity to satisfy the demand of drainage.

In another embodiment, the hardened surface 7 is on both sides of the grass furrow, and the hardened surface 7 has an inclined slope so that the runoff direction of the surface is towards the grass furrow. The hardened ground 7 is a pedestrian road, a driveway or a square, for example, can be used as a green belt for dividing a motor vehicle from a pedestrian road, and simultaneously utilizes plants to filter and precipitate pollution (oil stains, particulate matters and the like) on the motor vehicle road surface, and simultaneously relieves the problem of rainstorm and water accumulation of the area over the years. Specifically, the slope of the hardened surface 7 is 3-5 degrees, and of course, the slope of the hardened surface 7 with other specific values can be set according to actual requirements, which is not illustrated here.

Specifically, the both sides of grass ditch and the junction of sclerosis earth's surface 7 are equipped with kerbstone 8, be equipped with inlet 9 or diversion trench on the kerbstone 8, the runoff of sclerosis earth's surface 7 flows in along inlet 9 or diversion trench in the grass ditch, the design of this structure is in order to avoid surface ponding, the accessible is followed inlet 9 or diversion trench with rainwater leading-in the grass ditch fast. The overflow gap 6 is higher than the bottom of the grass ditch and lower than the diversion hole 9 or the diversion groove, and the overflow gap 6 is covered with a filtering grate.

In specific implementation, the depth of the grass ditch is not less than 100mm, the thickness of the planting soil layer 1 at the bottom of the grass ditch is 100-300mm, and the thickness of the filter layer 2 is 400-500 mm.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many changes and modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
