Detailed description of the invention
The utility model is described in further detail with specific embodiment 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 shown in Figure 1 to Figure 3; this utility model is a kind of leakage preventing structure of dilatation after Sanitary Landfill closes; described leakage preventing structure is arranged on shaping heap body 6; described leakage preventing structure includes dilatation impervious barrier 2, dilatation protective layer 3, closing impervious barrier 4 and the landfill gas guide layer 5 set gradually from top to bottom; described landfill gas guide layer 5 is arranged on the top of shaping heap body 6, and the top of described dilatation impervious barrier 2 is landfill heap body 1 after dilatation.
Leakage preventing structure of the present utility model has the advantages such as reasonability, safety, feasibility, and waste burying can obtain Optimum utilization, and unit are amount of landfill is higher, and construction cost is relatively low.
Need shaping heap body 6 is dealt with, it is ensured that shaping heap body 6 should be dried, smooth, compacting, the grade of side slope of shaping heap body 6 is not more than 1:3, and landfill absolute altitude often promotes 5m and should arrange one and be not less than the wide platform of 2m.
Described landfill gas guide layer 5 is disposed with ground floor geotechnique's filter screen 51, cobble lead layer 52, second layer geotechnique's filter screen 53 and pp geo textiles 54 from top to bottom, or directly uses soil engineering composite drainage network to construct in side slope.
In the present embodiment; the thickness of described cobble lead layer 52 is not less than 300mm; pp geo textiles 54 is preferably high-ductility polypropylene geotextiles; because the Organic substance in house refuse heap body is more; easily react under the effect of microorganism; differential settlement can be caused, use high-ductility polypropylene geotextiles can slow down the impact of differential settlement, the structure on protection upper strata.
Described closing impervious barrier 4 uses the matte HDPE(HighDensityPolyethylene that thickness is not less than 1.0mm, high density polyethylene (HDPE)) geomembrane or the thickness LLDPE(linear low density polyethylene (LLDPE) not less than 1.0mm) geomembrane constructs.
Described dilatation protective layer 3 is reinforced earth gauze pad and argillic horizon composition; described thickness of clay soil is 0.3m to 0.5m; the reinforced earth gauze pad of high intensity can play the effect of " pulling "; stably protect soil layer; it is thick that described argillic horizon is generally 0.3m～0.5m; should smooth, compacting, free from flaw, without loosening the soil, without hydrops and sharp object, and the longitudinal and transverse gradient is set according to the requirement of landfill gas guide layer.
Described dilatation impervious barrier 2 is disposed with geotechnique filter screen sealing coat 21, percolate guide cobble 22, soil engineering composite drainage network 23, filament nonwoven geotextiles protective layer 24, antiseepage HDPE geomembrane 25, GCL auxiliary seepage proof layer 26 from top to bottom.
In the present embodiment, the thickness of described percolate guide cobble 22 is not less than 300mm.The thickness of described antiseepage HDPE geomembrane 25 is not less than 1.5mm.And dilatation impervious barrier 2 must is fulfilled for resistance control and the collection of percolate and guide demand.
Leakage preventing structure of the present utility model is all use HDPE geomembrane as main impervious material, is because this structure and there is extremely low permeability, its infiltration coefficient≤1.0 × 10-13gcm/(cm2SPa), being a kind of flexibility, nontoxic, environmentally protective waterproofer, and do not have any material to dissolve under normal temperature condition, service life was up to 80～100 years.
Finally, the top of described dilatation impervious barrier 2 is landfill heap body 1 after dilatation, needs layered rolling when carrying out heap body landfill, covers in time, and landfill side slope not should be greater than 1:3.
The landfill gas of shaping heap body can be collected by leakage preventing structure of the present utility model, it is ensured that the landfill area of dilatation will not be adversely affected by the junk-heap body under closing impervious barrier；Meanwhile, composite anti-penetrating structure is used, it is ensured that the house refuse of new landfill will not leak, and pollutes environment, and can be collected its percolate produced.
And this utility model makes newly-built landfill yard need not carries out addressing, decrease the waste of land resource again, also alleviate that bring due to newly-built landfill yard with common people contradictions 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.
