Description
Technical field
The utility model is related to a kind of grass planting ditch structures.
Background technology
The fast development of urbanization has driven sustained economic growth, promotes all-side social progress, while also bringing tight
The heavy rain product damage caused by waterlogging evil of weight.Heavy rain product damage caused by waterlogging evil damages direct economy caused by urban water conservancy, agricultural, traffic, industry etc.
Lose it is inestimable, while the problems such as being broken out by human mortality, epidemic disease to society bring huge impact, caused by provide naturally
Source is reduced, environmental pollution and ecological degradation degree are even more to be difficult to estimate.
The reason of urban storm product damage caused by waterlogging evil is caused mainly to have reason of both weather and urban construction.From weather angle
For, due to global warming, water cycle generates variation, and rainfall spatial and temporal distributions are uneven, and city is caused heavy rain product damage caused by waterlogging occur
Evil；For urban construction angle, mainly urban architecture and hardening area is excessive, and vegetation coverage is too low or by broken
Bad, the water suction in city, water retention are poor, and followed by the drainability of pumping equipment is insufficient, rebuilds light pipe.
Utility model content
The purpose of this utility model is to be directed to the above shortcoming, provides a kind of grass planting ditch structure.
Scheme is a kind of grass planting ditch structure used by the utility model solves technical problem, including irrigation canals and ditches, the irrigation canals and ditches
It is inside provided with overflow well, trench bottom is laid with rainwater and transfers pipeline, and rainwater transfers pipeline connection overflow bottom side, the ditch
Divot, planting soil layer, medium-sand seam, the first geotextile layer, metalling, the second geotextiles are from top to bottom disposed in canal
Layer, rammed earth layer, the overflow well upper end are pierced by divot, and overflow well is located at the side setting in the part region of metalling
There is the water-permeable pipe inside connection overflow well.
Further, first geotextile layer is anti-seepage geotextile layer.
Further, second geotextile layer is filtering geotextile layer or anti-seepage geotextile layer.
Further, upper circumference offers several permeable holes in the water-permeable pipe.
Further, the overflow well upper end is provided with grille mesh cover.
Further, the grain size of the medium coarse sand in the medium-sand seam is less than 5 millimeters.
Further, the grain size of the rubble in the metalling is 5~20 millimeters.
Compared with prior art, the utility model has the advantages that：Simple in structure, reasonable design is beautified the environment,
Rainwater can be effectively detained, promote the infiltration of soil, slow down the flow velocity of rainwater, conserve water and soil, cutting down run-off reduces instantaneous flood
Peak flow, meanwhile, rainwater can be recycled.
Description of the drawings
The utility model patent is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
In figure：
1- divots；2- planting soil layers；3- medium-sand seams；The first geotextile layers of 4-；5- metallings；The second geotextiles of 6-
Layer；7- rammed earth layers；8- overflow wells；9- grade elevations；10- water-permeable pipes；11- rainwater connecting tubes.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of grass planting ditch structure, including irrigation canals and ditches, it is provided with overflow well in the irrigation canals and ditches, trench bottom is laid with
Rainwater transfers pipeline, and rainwater transfers pipeline connection overflow bottom side, turf is from top to bottom disposed in the irrigation canals and ditches
Layer, planting soil layer, medium-sand seam, the first geotextile layer, metalling, the second geotextile layer, rammed earth layer, on the overflow well
End is pierced by divot, and the side that overflow well is located at the part region of metalling is provided with the water-permeable pipe being connected to inside overflow well.
In the present embodiment, first geotextile layer is anti-seepage geotextile layer.
In the present embodiment, second geotextile layer is filtering geotextile layer or anti-seepage geotextile layer, the second geotextiles
Layer setting is less than 3m in bottom of trench, from building and uses anti-seepage geotextile, and other bottoms of trench are using filtering geotextiles.
In the present embodiment, upper circumference offers several permeable holes in the water-permeable pipe.
In the present embodiment, the overflow well upper end is provided with grille mesh cover.
In the present embodiment, the grain size of the medium coarse sand in the medium-sand seam is less than 5 millimeters.
In the present embodiment, the grain size of the rubble in the metalling is 5~20 millimeters.
In the present embodiment, the preferable soil filter layer of water penetration is used, while being laid with rainwater in trench bottom and having turned
Defeated pipeline substantially increases infiltration, transmission, delay and the detergent power of rainwater, reduces damage of the water logging to vegetation, improve
The utilizing status of rainwater plays a good role to the collection of rainwater, and has beautified environment, and the drying of grass planting ditch is kept to make
Tremendous contribution.Grass planting ditch can effectively be detained rainwater, promote the infiltration of soil.Meanwhile it can also slow down the stream of rainwater
Speed conserves water and soil, and cuts down run-off.Grass planting ditch also plays preferable effect for the removal and migration of pollutant.Grass planting ditch
Divot covers the surface of shallow ridges, and the expense spent is relatively low, while management operating is convenient.Grass planting ditch has both landscape ornamental value
Can, it can substitute traditional rain drainage pipe, delivering rainwater in certain areas.Grass planting ditch is to the main table of the reduction of runoff
It is now the reduction of the reduction and runoff peak value of runoff volume.The reduction of runoff volume is mainly shown as：When rainfall is smaller, grass planting
Ditch is mainly based on soil permeability；When the rainfall of moderate strength, grass planting ditch mainly to reduce flow velocity, is cut down based on runoff；It is high-strength
When spending rainfall, grass planting ditch is mainly to transfer based on the characteristic of rainwater.
Above-listed preferred embodiment has been further described the purpose of this utility model, technical solution and advantage,
It should be understood that the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this practicality
Within novel protection domain.
