Specific embodiment
With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
It is clear, be fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole realities
Example is applied, based on the embodiment in the utility model, those of ordinary skill in the art institute without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model embodiment provides a kind of grass planting ditch for sponge city, grass planting ditch interval is set
Between greenery patches 10 between Zhi highways 11 and pavement 12, herbaceous plant and xylophyta can also be planted on grass planting ditch, is had
The effect of landscape.Grass planting ditch is disposed with vegetable layer 1, planting soil layer 2, sandy gravel stratum 4, half layer of sand 5 and naturally plain from the top down
Soil layer 6, rainwater from vegetable layer 1 gradually downward deeply, flow through planting soil layer 2, sandy gravel stratum 4, half layer of sand 5 until naturally element soil layer 6,
Wherein planting soil layer 2, sandy gravel stratum 4, half layer of sand 5 are respectively provided with rainwater the effect of filtration, purification.
In specific embodiment of the utility model, 1 concave camber of vegetable layer, both sides and the greenery patches 10 of vegetable layer 1
Upper surface it is concordant, be conducive to rainwater and flow to grass planting ditch, and deposited in the vegetable layer 1 of grass planting ditch.Ladder is provided on vegetable layer 1
Platform 9, halfpace 9 at least 8, halfpace 9 is made of side and plane, and the plane of halfpace 9 is parallel to the upper surface in greenery patches, halfpace 9
Side along the upper surface of vegetable layer 1 diagonally downward.The design of halfpace 9 increases upper end residence time of the rainwater in vegetable layer 1,
Shared the pressure of the water suction of the lowest part of vegetable layer 1, infiltration, water purification, it is ensured that the water suction of entire grass planting ditch, infiltration, water purification and
The ability of water storage maximizes.
In specific embodiment of the utility model, it is provided on the side that greenery patches 10 is in contact with grass planting ditch higher than vegetation
First draining soakaway trench 8 of layer 1, one end connection municipal drain of the first draining soakaway trench 8, the first draining soakaway trench 8 are set
There are 2~5.When amount of rainfall is excessive or encounters flood, because the water-holding capacity of grass planting ditch is limited, rainwater is in grass planting
The vegetable layer 1 of ditch largely deposits, and the recess of vegetable layer 1 is caused to be full of water, at this moment the first draining soakaway trench 8 just plays draining
Effect, the drainage pipeline that the water being deposited in vegetable layer 1 will be delivered directly to city by the first draining soakaway trench 8 works as plant
When the water surface of water in tegillum 1 is less than the first draining soakaway trench 8, remaining rainwater will be absorbed water by grass planting ditch, after purified treatment,
Two draining soakaway trench 7 are finally flowed into, enter municipal drainpipe from the second draining soakaway trench 7.
As a preferred embodiment of the utility model, the width of grass planting ditch is equal to the width in greenery patches 10, the length of grass planting ditch
For 6~12m, the distance of upper surface to the lower surface of half layer of sand 5 of vegetable layer 1 is 40~60cm.
As another preferred embodiment of the utility model, the infiltration on the first draining soakaway trench 8 and the second draining soakaway trench 7
Earth-retaining layer is provided on hole, earth-retaining layer is to ensure that the water in the first draining soakaway trench 8 and the second draining soakaway trench 7 can be smoothly
To exosmosis, but external soil cannot enter in pipe.The inlet of first draining soakaway trench 8 and the second draining soakaway trench 7
It is provided with filter screen, filter screen is the house refuse for stopping city, such as food pack, pericarp etc. enter the first draining and seep water
In 8 and second draining soakaway trench 7 of pipe, it is ensured that the flow in pipe is all smooth.
As another preferred embodiment of the utility model, geotextiles 3, half sand are provided between planting soil layer 2 and sandy gravel stratum 4
The second draining soakaway trench 7 is provided in layer 5, the second draining soakaway trench 7 is arranged parallel to each other, and one end converges and connects municipal row
Water pipe.Sandy gravel stratum 4 is filtered deep rainwater purification, and half layer of sand, 5 one side is filtered rainwater purification, on the other hand
The flow velocity of flow is reduced, extends residence time of the water in 4 and half layer of sand 5 of sandy gravel stratum, plays better clean-up effect.Geotextiles
3 be that the native of planting soil layer 2 in order to prevent is adulterated into sandy gravel stratum 4.
In conclusion the utility model has the advantages of simple structure, rainwater is longer in the residence time of vegetable layer, has and more preferably inhales
Water, infiltration, water storage and the ability of water purification, while there is more superior drainability.
Disclosed above is only the preferred embodiment of the utility model, and still, the utility model embodiment is not limited to
This, the changes that any person skilled in the art can think of should all fall into the scope of protection of the utility model.
