Abstract
The utility model provides a kind of landfill slopes protective layer structure, the slope protection layer (3) tiled by packed rubble is arranged on the impervious barrier (2) of side slope above to protect impervious barrier, packed rubble is the cloth bag (31) filling rubble, the particle diameter of packed rubble is d, wherein 2cm≤d≤4cm; Cloth bag is non-woven geotextile bag.Compared with prior art, can effectively avoid after being provided with slope protection layer in rubbish (5) landfill process, impervious barrier is punctured by sharppointed article and is damaged, slope protection layer simultaneously (3) is tiled by packed rubble and is formed, packed rubble impurity is few, go out even if slope protection layer does not have trash flow under the washing away of rainwater or percolate yet, blocking percolate discharge guiding pipe, and do not absorb water, slope protection layer is avoided to absorb water in a large number in rainy period increase slope load, in addition, crushed stone is stablized, after being soaked by rainwater, also can not deform and the side slope of different gradient can be adapted to.
Description
Technical field
The utility model relates to technical field of domestic garbage treatment, particularly a kind of landfill slopes protective layer structure.
Background technology
When carrying out garbage loading embeading, in order to prevent poisonous and hazardous contaminants soil and groundwater source in percolate, needing rubbish and surrounding formation to separate, namely separating with soil and groundwater.In order to reach this purpose, refuse landfill needs to arrange impervious barrier on waste burying, is generally lay antiseepage film, by rubbish and surrounding formation completely isolated, stop percolate to permeate the ground and landfill yard surrounding soil and underground water polluted.After rubbish is transported to landfill yard, be poured in waste burying, by earth mover, rubbish is bulldozed, and adopt rolling machine to carry out compacting, landfill height successively raises along with the increase of quantity of refuse, easily damage impervious barrier with compacting process being bulldozed of rubbish, the sharp object especially in rubbish can puncture impervious barrier.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of landfill slopes protective layer structure protecting impervious barrier.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of landfill slopes protective layer structure, to protect impervious barrier above the impervious barrier that the described slope protection layer tiled by packed rubble is arranged on side slope, described packed rubble is the cloth bag filling rubble, the particle diameter of the rubble of described packed rubble is d, wherein 2cm≤d≤4cm; Described cloth bag is non-woven geotextile bag.
Further, the suture of described cloth bag is polyester thread.
Further, described cloth bag is of a size of 80 × 50cm.
Compared with prior art, by arranging slope protection Rotating fields on the impervious barrier of side slope, impervious barrier is avoided to be punctured by sharp object in garbage loading embeading process and be damaged, slope protection layer is tiled by packed rubble and forms, packed rubble impurity is few, be not easy to block percolate discharge guiding pipe, its good water permeability, slope protection layer is avoided to absorb water in a large number in rainy period and increase slope load, the impervious barrier causing slope protection layer to be even inconjunction with lower floor slippage or cave in together, and the Stability Analysis of Structures of rubble, after being soaked by rainwater, also can not deform, the side slope of different gradient can be adapted to.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is explained in further detail.
Fig. 1 is the waste burying cross section structure schematic diagram after being provided with the utility model protective layer structure.
Fig. 2 is the structural representation of the cloth bag of packed rubble in the utility model protective layer structure.
Detailed description of the invention
As shown in Figure 1; soil basal layer 1, impervious barrier 2, guide layer 4 is provided with from bottom to top successively above the place of waste burying; and after being provided with slope protection layer, above the sidewall side slope of waste burying, be provided with soil basal layer 1, impervious barrier 2, slope protection layer 3 from bottom to top successively.5, rubbish is deposited in the enclosing region of guide layer 4 and slope protection layer 3 formation.
It is to be protected the impervious barrier 2 of side slope that the sidewall side slope of waste burying arranges slope protection layer 3.Prevent being bulldozed and compacting process at rubbish 5, in rubbish 5, sharp object easily punctures the impervious barrier 2 of side slope and damages impervious barrier 2.Slope protection layer 3 is tiled by packed rubble to form, and packed rubble is then for filling the cloth bag 31 of rubble.Packed rubble is adopted to be because the impurity of packed rubble is few, even if slope protection layer 3, under the souring of rainwater or rubbish 5 percolate, does not have trash flow yet and goes out, block percolate discharge guiding pipe, cause the paralysis of percolate guide system like this.
Secondly, the good water permeability of packed rubble, not easily absorbs water; can avoid in rainy period because topping 3 absorbs water in a large number; the load significantly increasing side slope causes topping 3 slippage or caves in, impervious barrier 2 slump together of even related lower floor, causes impervious barrier 2 large area to be destroyed.In addition, the Stability Analysis of Structures of rubble, rains after period soaked by rainwater, also can not deform and can adapt to the side slope of different gradient.When the packed rubble of on-the-spot tiling is as slope protection layer 3, rubble can be loaded at the scene to cloth bag 31 li, then sew up sack, then tile.
After practical operation, the particle diameter of rubble is d, and as 2cm≤d≤4cm, the slope protection layer 3 tiled by packed rubble has optimum efficiency.The calcium carbonate of rubble is w, and preferred version is w≤10%.Because slope protection layer 3 often exposes to the sun and rain, therefore select the cloth bag 31 of packed rubble for non-woven geotextile bag, the good penetrability of non-woven geotextile bag, high temperature resistant, ageing-resistant, corrosion-resistant, can antiultraviolet, be not easy breakage, increase the service life.As shown in Figure 2, the sack polyester thread 32 of cloth bag 31 unites by a seam, and the intensity of polyester thread 32 is high, heat resistance and abrasion resistance good, when being well suited for exposing to the sun and rain for slope protection layer 3.Can also determine according to site environments such as the gradient of side slope and the degree of depth size selecting cloth bag 31, preferred version is, cloth bag 31 is of a size of 80 × 50cm.
Claims (3)
1. a landfill slopes protective layer structure, it is characterized in that, the described slope protection layer (3) tiled by packed rubble is arranged on the impervious barrier (2) of side slope above to protect impervious barrier (2), described packed rubble is the cloth bag (31) filling rubble, the particle diameter of the rubble of described packed rubble is d, wherein 2cm≤d≤4cm; Described cloth bag (31) is non-woven geotextile bag.
