Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As it is shown in figure 1, the household refuse landfill sites closing structure that this utility model is a kind of twice laid, it is disposed with basal layer 1, basic supporting layer 2, exhaust level 3, impervious barrier 4, drainage blanket 5 and vegetable layer 6 from lower to upper.
Described basal layer 1 is the junk-heap body after shaping, when junk-heap body plastic operation excavation, takes inclined plane delamination operation, and the rubbish dug out to backfill in time, ensures that the fillings such as the crack because junk-heap body differential settlement causes, ditch, cavity are closely knit.
Described junk-heap body answers compaction in layers, uses special compactor to be compacted, and compacted density is more than 800kg/m3, and the end face gradient of junk-heap body is not less than 5%.Setting table stepwise closing slope when the grade of side slope of described junk-heap body is more than 10%, the width of described step is not less than 2m, and height is not more than 5m, and the grade of side slope of described step is not preferably greater than 1:3.
Described basic supporting layer 2 for building waste and is laid on whole basal layer 1 top, and whole Closure cover system is played support, Stabilization by basic supporting layer 2, for resisting the destruction to Closure cover system of the junk-heap body differential settlement.The laying depth of described basic supporting layer 2 is at 250 ~ 300mm, and the particle size of building waste, at 80mm ~ 150mm, fills dregs of incinerator between the gap of described building waste.During concrete operations, should first lay building waste, more uniformly fill space with dregs of incinerator, ensure building waste layer surfacing no concave-convex simultaneously, with tamper-proof topsoil work composite, this layer simultaneously works as the effect of auxiliary exhaust.
Described exhaust level 3 is the mixture of slag and gravel, and volume mixture ratio is 3 ~ 4:1, and wherein the particle diameter of slag is 30-50mm at 5 ~ 10mm, the particle diameter of gravel at 30 ~ 50mm, the thickness of described exhaust level 3, and infiltration coefficient is more than 1 × 10-2cm/s.When being embodied as, should first lay gravel, more uniformly fill space with dregs of incinerator；It is positioned at exhaust level 3 at side slope to be substituted by the thickness soil engineering composite drainage network not less than 6.0mm.
Described impervious barrier 4 includes the main impervious barrier on upper strata and the secondary impervious barrier of bottom, and described time impervious barrier is stirred formed by dregs of incinerator, flyash, clay and four kinds of material mixing of mud, and infiltration coefficient is less than 1 × 10-5cm/s.After pretreatment, the weight of each composition material is joined for waste incineration slag 1-3 part, flyash 1-2 part, clay 1-5 part, mud 1-5 part.
Wherein dregs of incinerator pretreatment operation: removed by metallics therein by magnetic plant, is then passed through disintegrating machine and carries out broken screening, it is ensured that the particle diameter of dregs of incinerator is respectively less than 5mm.
The pretreatment operation of described flyash: pulverize flyash, removes the particle diameter granule more than 5mm.
The pretreatment operation of described clay: pulverize clay, removes the particle diameter granule more than 5mm.The pretreatment operation of described mud: municipal sludge is carried out simple dehydration, moisture content is 80% ~ 85%.
Secondary impervious barrier, while ensureing antiseepage coefficient and reducing cohesive soil consumption, can effectively be disposed for waste incineration residue, municipal sludge and flyash the like waste and provide a kind of approach.
Described main impervious barrier is HDPE geomembrane thick for 1.0 ~ 1.5mm or the LLDPE geomembrane of 1.0 ~ 1.5mm thickness, and infiltration coefficient is less than 1 × 10-7cm/s.HDPE geomembrane or LLDPE geomembrane use double slit sweat soldering and the mode of single seam extruding welding, and the lap width of seam is: sweat soldering 100mm ± 20mm, extruding welding 75mm ± 20mm.
Described drainage blanket 5 is made up of 300mm thickness cobble or 300mm thickness gravel or the thickness soil engineering composite drainage network not less than 6.0mm is constituted, and to realize the smooth and easy guide of rainwater, if selecting cobble or gravel, then should arrange one layer of 200g/m on 300mm lead layer2Geotechnique's filter screen, as loaded filter, prevents cobble, gravel drainage blanket generation silting, the soil engineering composite drainage network not less than 6.0mm of the slope drainage layer application simultaneously from replacing.
If selecting soil engineering composite drainage network to make drainage blanket, its web-roll core is 6.0mm earthwork grid, and the top and the bottom of web-roll core are all covered with filament nonwoven geotextiles, and filament nonwoven geotextiles is not less than 200g/m2.Rainwater can flow into web-roll core after being filtered by filament nonwoven geotextiles, and the most quickly guide is gone out.Meanwhile, the web-roll core of soil engineering composite drainage network has certain longitudinal tensile strength, can ensure the stability of closing structure to greatest extent.
Described vegetable layer 6 is made up of the support soil layer of bottom and the nutrition soil layer on upper strata, supports that soil layer is constituted by being compacted soil layer, and thickness is more than 450mm, and infiltration coefficient is more than 1 × 10-4cm/s.Nutrition soil layer is made up of common soil and mineralized waste fertile soil, thickness should be greater than 150mm, mineralized waste fertile soil adding proportion is 25%～50%, and described vegetable layer 6, for the addition of mineralized waste soil layer humous, utilizes for the mineralized waste fertile soil after resettlement and provides effective way.
Nutrition soil layer answers compaction in layers, greening of closing can be planted with turf and the shrub with certain economic value, should not plant the high megaphanerophyte that root system penetration power is strong, vegetation selects rationally to select according to situations such as local edaphic condition, climate rainfall condition, temperature lights.
This utility model can reduce the impact of landfill pollutant confrontation surrounding to greatest extent, provide a kind of approach for municipal sludge, incineration residue, flyash, the disposal of mineralized waste fertile soil the like waste simultaneously, the quality that refuse landfill sealing covers can not only be ensured, meet all technical closed, improve the bad border of refuse landfill the most greatly, achieve ecological, environmental protective, save land resource simultaneously.
Embodiment described above is only the preferred embodiment lifted by absolutely proving this utility model, and protection domain of the present utility model is not limited to this.The equivalent that those skilled in the art are made on the basis of this utility model substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
