Description

Side slope seepage-proofing structure of refuse landfill

Technical Field

The utility model belongs to the technical field of refuse landfills, and particularly relates to a side slope seepage-proofing structure of a refuse landfill.

Background

The refuse landfill is generally treated by adopting a layered earthing and landfill mode, and a layer of loess is covered after a layer of refuse is piled up, so that the pollution of the refuse is easily reduced. The construction of the refuse landfill comprises the procedures of site selection, design and construction, landfill waste entry conditions, operation, field sealing, post maintenance and management, pollutant control and monitoring and the like.

The refuse landfill has higher requirements on the anti-seepage structure, and the ecological environment near the refuse landfill is influenced among the anti-seepage effects.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides the side slope seepage-proofing structure of the refuse landfill, which improves the seepage-proofing property of refuse penetrating fluid and avoids polluting soil through the arrangement of the seepage-proofing system layer, and avoids the occurrence of retention by timely treating the seepage through the seepage treatment system.

The technical scheme adopted by the utility model is as follows: the utility model relates to a side slope seepage-proofing structure of a refuse landfill, which comprises the refuse landfill, a compacted base layer, a soil seepage-proofing layer, a seepage-proofing system layer and a leachate treatment system, wherein the compacted base layer, the soil seepage-proofing layer and the seepage-proofing system layer are arranged in the refuse landfill from bottom to top, the leachate treatment system is arranged close to the refuse landfill, and the seepage-proofing system layer is sequentially provided with a GLC cushion layer, a HDPE film layer, a geosynthetic layer and a covering soil layer from bottom to top.

Further, the geosynthetic layer comprises a lower geotechnical composite drainage net, a geomembrane and an upper geotechnical composite drainage net which are sequentially arranged from bottom to top.

And furthermore, a leachate collecting system is arranged on the soil impermeable layer and is connected with the leachate treatment system.

Further, the control range of the overlapping width of the GLC cushion layer is 250 +/-50 mm.

Furthermore, the GLC cushion layer close to the side slope in the refuse landfill is lapped and pressed on the GLC cushion layer close to the center of the refuse landfill.

The utility model with the structure has the following beneficial effects: according to the side slope seepage-proofing structure of the refuse landfill, the seepage-proofing performance of the refuse penetrating fluid is improved through the arrangement of the seepage-proofing system layer, the pollution to the soil is avoided, and the leachate is treated in time through the leachate treatment system, so that the accumulation is avoided.
