Abstract
The utility model discloses a landfill surface sealing system which is sequentially provided with a surface layer, a protective layer, a drainage layer, an impermeable layer and an exhaust layer from top to bottom. The surface layer has a land restoration function, the protective layer is used for preventing plants or animals on the upper layer from damaging the lower layer, the drainage layer can effectively reduce drainage pressure on the impermeable layer on the lower portion, the impermeable layer can effectively prevent permeable water from flowing into landfill rubbish, and the exhaust layer is mainly used for controlling gas of a landfill to prevent high-pressure gas from damaging the impermeable layer. In a word, the landfill surface sealing system is good in sealing effect and has an exhaust function, and the service life of the landfill surface sealing system is prolonged.
Description
Technical field
The utility model relates to a kind of sealing system, especially relates to a kind of landfill yard surface sealed system, belongs to solid waste processing system technical field.
Background technology
The processing mode of solid waste is a lot, and wherein, landfill disposal has that technique is simple, cost is lower, is applicable to the advantage of polytype solid waste, and still, the subject matter of this kind of processing mode is the collection control problem of percolate.In actual application process, its sealing system is unsatisfactory, once destroy, also be difficult to order, and due to the raising of Dui Huan Jing Ran control criterion, its disposal costs also constantly increases, and this brings the difficulty in very large application to the disposal options of this kind of solid waste undoubtedly.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide the landfill yard surface sealed system of a kind of good sealing effect, long service life.
For achieving the above object, the utility model is to realize by following technical scheme:
A kind of landfill yard surface sealed system, is characterized in that, is sequentially set with from top to bottom top layer, topping, drainage blanket, impervious barrier and exhaust level.
Further, in described top layer, be also provided with surface water key-course.
The material on described top layer is humus soil.And the thickness on described top layer is greater than 60cm.
The material of described topping is natural soil or gravel.
The permeability rate of described drainage blanket is greater than 10
-2cm/s, gradient is greater than 4%.
The thickness of described impervious barrier is greater than 60cm, and its material is for being HPDE film.
Described exhaust level material is any in sand, gravel, earthwork grid.And in the exhaust level of stating, be also provided with gas guide pipeline.
And further, between described top layer and topping, between topping and drainage blanket, between drainage blanket and impervious barrier, and between impervious barrier and exhaust level, being provided with separation layer, the material of described separation layer is geotextiles.
The beneficial effects of the utility model are: top layer described in the utility model has land restoration function; described topping is the destruction to lower floor for the protection of plant or the animal etc. on upper strata; described drainage blanket can effectively reduce the book pressure of the impervious barrier to bottom; described impervious barrier can effectively prevent that the water infiltrating from entering in landfill refuse; described exhaust level is mainly used in controlling the gas of landfill yard; avoid the destruction of gases at high pressure to impervious barrier; in a word; the utility model good sealing effect; and the function that has exhaust concurrently, has extended application life.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model one embodiment.
In figure, main Reference numeral implication is:
1, top layer 2, topping 3, drainage blanket
4, impervious barrier 5, exhaust level 6, separation layer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is carried out to concrete introduction.
Fig. 1 is the structural representation of the utility model one embodiment.
As shown in Figure 1: a kind of landfill yard surface sealed system, is sequentially set with top layer 1, topping 2, drainage blanket 3, impervious barrier 4 and exhaust level 5 from top to bottom.Wherein, in described top layer 1, be also provided with surface water key-course, and the material on described top layer 1 is humus soil, and its thickness is greater than 60cm, in the present embodiment, its thickness is 75cm.And the material of described topping 2 is natural soil, certainly, it can be also gravel.In addition, the permeability rate of described drainage blanket 3 is greater than 10
-2cm/s, gradient is greater than 4%.The thickness of described impervious barrier is greater than 60cm, and in the present embodiment, its thickness is 65cm, and its material is for being HPDE film.Described exhaust level 5 materials are sand, and it can be also gravel or earthwork grid certainly, and is also provided with gas guide pipeline in the exhaust level 5 of stating.
In addition, in the present embodiment, between described top layer 1 and topping 2, between topping 2 and drainage blanket 3, between drainage blanket 3 and impervious barrier 4, and be provided with separation layer 6 between impervious barrier 4 and exhaust level 5, and the material of described separation layer 6 is geotextiles.
Top layer 1 described in the utility model has land restoration function; described topping 2 is the destruction to lower floor for the protection of plant or the animal etc. on upper strata; described drainage blanket 3 can effectively reduce the book pressure of the impervious barrier to bottom; described impervious barrier 4 can effectively prevent that the water infiltrating from entering in landfill refuse; described exhaust level 5 is mainly used in controlling the gas of landfill yard; avoid the destruction of gases at high pressure to impervious barrier; in a word; the utility model good sealing effect; and the function that has exhaust concurrently, has extended application life.
The utility model is illustrated and should be appreciated that above-described embodiment does not limit the utility model in any form according to above-described embodiment, and all employings are equal to replaces or the technical scheme that obtains of equivalent transformation mode, within all dropping on protection domain of the present utility model.
