Abstract
The invention discloses a landfill surface filling system. The landfill surface filling system is sequentially provided with a surface layer, a protection layer, a drainage layer, an anti-seepage layer and an exhaust layer from top to bottom. The surface layer has the land restoration function, the protection layer is used for protecting the lower layer against damage caused by plants or animals or the like on the upper layer, the drainage layer can effectively reduce pressure on the lower anti-seepage layer, the anti-seepage layer can effectively prevent seeping water from entering buried waste, and the exhaust layer is mainly used for controlling gas of a landfill and avoiding damage to the anti-seepage layer caused by high pressure gas. In short, the landfill surface sealing system is good in sealing effect and has the exhaust function, and service life is prolonged.
Description
Technical field
The present invention relates to a kind of sealing system, especially relate to a kind of landfill yard surface sealed system, belong 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.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention 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 present invention is achieved by the following technical solutions:
A 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 invention has the beneficial effects as follows: top layer of the present invention has land restoration function; described topping is for the protection of the plant on upper strata or the destruction of animal Deng Dui lower floor; described drainage blanket can effectively reduce the book pressure to the impervious barrier of 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; good sealing effect of the present invention; and the function that has exhaust concurrently, has extended application life.
