Detailed description of the invention
Below in conjunction with specific embodiment, described online ecological vegetation infiltration shallow ridges is described further, stillProtection domain of the present utility model is not limited to this.
Embodiment 1
A kind of online ecological vegetation infiltration shallow ridges, it comprises infiltration shallow ridges section that continuous alternate cycles arranges 1, twoHeavy weir body section 2 and delaying basin section 3; After every 100m infiltration shallow ridges section 1, set gradually the double weir body section 2 of long 2mDelaying basin section 3 with 20m; Described infiltration shallow ridges section 1 comprises hard shallow ridges and the shallow ridges with slope vegetation protection; DescribedThe contiguous car lane of hard shallow ridges; The described shallow ridges next-door neighbour hard shallow ridges with slope vegetation protection, and be divided into successively mildDistrict 4, sloped region A5, buffering area 6, sloped region B7 and bottom of trench 8; The cross section of described infiltration shallow ridges section 1 certainlyUpper and under be followed successively by vegetable layer, from embedded ecological brick layer, plantation soil layer, geotechnological layer of cloth, rubble packing layer A, brokenHardcore layer B, waterproofing geomembrane; In the middle of described rubble packing layer B, bury diameter 6cm Water penetrative flexible pipe underground.
The radius of described hard shallow ridges is 5cm. The section gradient of described sloped region A and sloped region B is all designed to4:5. Described sloped region A5, buffering area 6, sloped region B7 and bottom of trench 8 formations have the trapezoidal of two-stage step;Trapezoidal aggregate depth 40cm, bottom width 40cm; Described planting soil layer depth 30cm, the dark 10cm of rubble packing layer A, rubbleThe dark 20cm of packing layer B.
Hard shallow ridges: contiguous car lane, the rainfall that is 2-3mm for intensity, plays the dirt of preliminary filtration rainwaterDye the effect of thing, and relatively better clean, in the time of rainfall intensity >=3mm, rainwater flows to darker Glassed swale, canReduce through flow velocity.
The shallow ridges section gradient with slope vegetation protection: can improve body of wall resistance to capsizing. Shallow ridges with slope vegetation protection:Cross is installed from embedded ecological brick on it, compared with parabolic type shallow ridges convenient construction, can be better, keep more lastinglyShallow ridges form; Bottom of trench below is provided with the dark planting soil of 30cm, lays anti-seepage geotextile, prevents that planting soil is with under rainwaterInfiltrate in rubble packing layer, intercept sand gravel and filter; 10cm rubble filler A, 20cm rubble packing layer B,Waterproofing geomembrane is laid by lower floor, and effectively catching sandslide, buries diameter 6cm underground in rubble packing layer B permeable softPipe, the rainwater vegetation infiltration shallow ridges of flowing through, the biologic packing materials such as gravitational settling, vegetation, planting soil and gravel,Under the actings in conjunction such as geotextiles is filtered, permeates, absorbed, the interior biomembrane degraded of biologic packing material, remove rain water pollutant,Reach the object of collecting rainwater and controlling runoff pollution. After filtering, rain water-harvesting, in Water penetrative flexible pipe, is further receivedCollect to device for collecting rain water and again utilize. When bottom of trench is anhydrous, in Water penetrative flexible pipe, rainwater is upwards supported and is planted through osmosisGrown water.
From embedded ecological brick: can be by domatic shallow ridges N facet, ecological brick rough surface, the abrasive resistance of being decomposed intoStrengthen, resist rainwater impact property and strengthen. Can prevent that rainwater is to the washing away of Glassed swale furrow bank, simultaneously coarseSurface further increases antiscour intensity, and holds back part rain and impurity; On it, reserved ecological hole, can plant and plantThing, forms duplicate protection, ensures the integrality of Glassed swale, and on facet, the soil body, vegetation is stable, reachesWhole domatic stablizing, solves the soil losses problem of original ecological revetment. The permanent rainfall runoff flow that reduces,Plant grows fine, and breaks away from the poor adverse effect of traditional gutter landscape effect, with the perfect knot of periphery Afforestation LandscapeClose.
The height 20cm of described double weir body section, wide 90-110cm, the long 100cm of single-stage; Body two ends, every grade of weir are darkEnter bottom of trench 8; Weir surface layer comprises packed plantation argillic horizon and rubble packing layer C, and its both sides are sprinkled with easy sward seed;Rubble packing layer C below is also provided with packed rubble packing layer D; Yan Ti lower floor comprises the plantation that 30cm is dark successivelySoil layer, geotechnological layer of cloth, dark rubble packing layer F and the waterproofing geomembrane of rubble packing layer E, 20cm that 10cm is darkLayer; Every grade of weir body has 4 hold-down bars to be inserted to rubble packing layer F from top layer, ensures weir body safety and firmness; Rubble is filled outIn the middle of bed of material F, bury diameter 8cm Water penetrative flexible pipe underground. Microorganism and the shape had by packed rubble packing layer DThe vegetation growing on the biomembrane becoming and packed plantation clay further purifies water body.
Double weir body: shallow ridges is goed deep at body two ends, every grade of weir. Flood is walked top layer, and when rainfall is larger, rainwater passes throughTrapezoidal shallow ridges district, reduces through flow velocity through double weir body, and little Shui Zou lower floor intercepts rainwater and directly flows to delaying basin,After the infiltration of infiltration shallow ridges, double weir body is processed, import device for collecting rain water through Water penetrative flexible pipe, improve pollutantTreatment effect.
The cross section of described delaying basin section be all followed successively by from top to bottom vegetable layer, from embedded ecological brick layer, plantation soil layer,Geotechnique's layer of cloth, rubble filler X layer, rubble filler Y layer and waterproofing geomembrane; The dark 50cm of trapezoidal delaying basin, ditchEnd planting soil layer depth 30cm, the dark 30cm of rubble filler X, the dark 40cm of rubble filler Y, described rubble filler Y layerCentre is buried diameter 8cm Water penetrative flexible pipe underground.
Delaying basin: cost is low relatively, construction is simple. Extend the rainwater time of staying, rainwater is after the body of weir under flow velocityFall 1) utilize Action of Gravity Field, by elementary removings such as particle, organic matter, metals; 2) by algae in pond andMuskeg absorption, removes the rain water pollutants such as hydro carbons; 3) by absorption such as bottom of trench below gravel, cobblesProperty solid packing and upper attached microbial colony thereof the biomembrane that forms, produce stronger suction-operated and carry out biology and fallSeparate, thus purifying water body. Between planting soil Hole and graded broken stone, hole is that condition has been created in water and soil exchange, largeWhen rain, in shallow ridges, water storage permeates downwards, makes full use of the capacity of flood storage of vegetation, soil and rubble, postpones heavy rainThe flood peak time, precipitation gulf Nei Jing top layer vegetation and below the multi-filtering such as gravel, rain water pollutant is entered oneStep absorbs degraded, and after precipitation, filtration, infiltration, absorption, rainwater is arranged with certain flow through Water penetrative flexible pipe againTo device for collecting rain water or lead to municipal drainage pipeline, further purify recycling.
