It is preferred that, intensive kind is implanted with single file hedgerow on the linkage section, and plant height is higher than 30cm.
Compared with prior art, the utility model has the advantages that：
Recessed greenery patches structure of the present utility model is using the sand setting effect for cutting dirty section, for the mud carried in Initial Runoff
Husky, impurity is retained；Simultaneously by the single file shrub zone closely planted in connect band, intercept the rubbish floated in runoff and hang
Float；The plant for the recessed greenery patches main part that adequately protects, has ensured the Runoff for entering recessed machine non-isolated band；Cut
Impurity, the pollutant stayed is easily cleared up, under the theory for meeting sponge urban construction, it is ensured that city appearance environment is unaffected.
Brief description of the drawings
By reading the detailed description made with reference to the following drawings to non-limiting example, other spies of the present utility model
Levy, objects and advantages will become more apparent upon：
Fig. 1 is the floor plan of the recessed greenery patches structure of the utility model；
Fig. 2 is the structural representation in the recessed greenery patches of the utility model；
Wherein, 1 is cuts dirty section, and 2 be curb, and 3 be shrub, and 4 be stormwater overflow mouthful, and 5 be plantation soil layer, and 6 be coating,
7 be gravel layer, and 8 be layer of sand, and 9 be curb osculum, and 10 be road, and 11 be pavement, and 12 be linkage section, and 13 be lower concave segment.
Embodiment
The utility model is described in detail with reference to embodiment.Following examples will be helpful to the technology of this area
Personnel further understand the utility model, but do not limit the utility model in any form.It should be pointed out that to this area
For those of ordinary skill, without departing from the concept of the premise utility, it can also make certain adjustments and improvements.These
Belong to protection domain of the present utility model.
Embodiment
The present embodiment is related to a kind of concave herbaceous field structure applied to both sides of the road machine non-isolated band.As shown in figure 1, flat
Face figure is from top to bottom followed successively by car lane, machine non-isolated band and bicycle lane.As shown in Fig. 2 concave herbaceous field structure is set
On machine non-isolated band between road 10 and pavement 11, include section dirty section 1, a lower concave segment 13 and the company of the two of both sides
Connect section 12.Wherein cut dirty section 1 and be disposed in proximity to the side of curb 2, and it is closely coupled with the inwall of curb 2；Cut under dirty section 1 is in
Concavity, recessed depth is 5cm~10cm with respect to the plane of road 10；Dirty section 1 is cut by poor (infiltration coefficient≤1 × 10 of water permeable ability-6m/
S) backfill is tamped, and whole segment length is unilateral wide to ensure that the runoff into machine non-isolated band is cutting the minimum of the dirty seepage flow of section 1
Degree accounts for 15%~20% of integrated machine non-isolated with bandwidth；Cut the strong vegetation of durability against pollution such as dirty a kind of plant greens grass of section；Cut dirty section
The lower end that 1 peak should be open with curb 2 is flushed, and the pollution concentration that effectively can be flowed into curb osculum 9 is high, carry
The Initial Runoff of silt carries out precipitation of damming.
The intensive kind of linkage section 12 of described section of dirty section 1 and lower concave segment 13 is implanted with single file hedgerow, based on shrub 3.In runoff
The larger solid pollutant of volume (rubbish and suspension of floating) can effectively be intercepted by the distinctive tight structure of hedgerow limb.It is logical
Cross and cut dirty section 1 and the R. concomitans of hedgerow, the silt, the rubbish of floating and suspension during rainfall entrained by Initial Runoff are cut
Stay, it is ensured that enter the basic water quality of the lower runoff of concave segment 13, and ensured the normal growth of the lower vegetation of concave segment 13, it is to avoid rubbish enters
Enter the lower concave segment 13 of machine non-isolated band and influence city appearance environment, increase the difficulty and cost of greening maintenance.
Lower concave segment 13 be located at recessed machine non-isolated band centre position, width account for machine non-isolated with bandwidth 60%~
70%, it is the main part of concave herbaceous field structure, is that rainfall runoff enters to blend the main place of purification.The recessed depth of lower concave segment 13
The relative plane of road 10 of degree is 150mm~250mm；Green land spreading structure is divided into four layers in lower concave segment 13, is respectively from top to bottom：
Coating 6, plantation soil layer 5, layer of sand 8, gravel layer 7, can further purify, infiltrate the relatively low rainfall runoff of pollution concentration.It is recessed
13 minimum points of section, less than the dirty minimum point of section 1 is cut, are that rainfall runoff remittance speed exceedes entering for concave herbaceous field when rainfall intensity is larger
Ability is oozed, to avoid region ponding excessive, one stormwater overflow mouthful 4, the rain are set every 10~15m on the lower center line of concave segment 13
Water overfall 4 is connected with subsurface stormwater pipeline；Stormwater overflow mouthful 4 absolute altitudes are flush to the plane of road 10, i.e. the inner product of concave segment 13 instantly
When water depth exceedes 10 plane of road, stormwater overflow mouthful 4 collects excessive runoff, and is discharged by municipal storm sewer.
As to the preferred of above-mentioned technical proposal, using having opening, or the curb 2 with water permeable ability, and
Opening lowest point absolute altitude cuts the dirty peak absolute altitude of section 1 higher than the recessed greenery patches.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on substantive content of the present utility model.
